I lost 180 pounds and my skin started to sag once i got into my mid 40's. I wanted to do something and have been researching what can be done about it. This is a really light clean serum with a pleasant smell hardly any at all but you can tell its good quailty. Has no oder and a small amount goes along way. I have freckles that become more noticeable in sun light. This Serum along qith vitamin c has started to fade them and my skin is radiant. I used this with a Dr. Pen Microneedling I purchased off Amazon. Noticed smoother skin, less wrinkles, in about 3 weeks. My skin is also taut and firmer than before. Soon I'll be ordering a hydra Pen!
I am completely shocked right now! My poor skin has become so tired and stressed looking after going through a bad divorce. I’m also a smoker too I admit. So after doing hours of homework and also being on a tight budget now, I decided to try using a micro-needling stamp and chose this as the first thing to put on right after using the stamp. I received both items and went for it yesterday. When I finished stamping and had tomato face/neck, I applied this and fell asleep in my recliner for about 3 hours before I woke up realizing I’d dozed off. When I got up and walked by the mirror I was like no way!! I wasn’t expecting anything at all other than my skin feeling a little better. But just doing these together one time is amazing! Wow! It’s got me excited to keep doing this regularly now to see what will be the result in 3 months! I also plan to add a vitamin C serum as well. I haven’t been pumped about something like this in a very long time!By the way, my pictures are untouched, except for blocking out my eyes in the first one -which is showing my skin earlier yesterday -and the result I woke up to!! (also untouched other than a zit I had on my nose lol!!!!)
I’ve struggled with maintaining a consistent texture and keeping my skin clear, especially when switching between morning and night routines. I was looking for a hyaluronic acid that wasn't too sticky but actually delivered deep hydration.The first thing I noticed about the Cosmedica Pure Hyaluronic Acid Serum is the consistency. It’s very lightweight and absorbs almost instantly. Unlike other serums I’ve tried, it doesn't leave a tacky residue, which makes it perfect for layering under my morning makeup or a heavier night cream.This has become a "must-have" for two main reasons:Smoothness: My skin feels significantly softer to the touch. It plumps up those fine dehydration lines instantly.Clarity: The biggest surprise was how it helps keep my skin blemish-free. I apply it at night, and by the morning, my skin looks noticeably clearer and more "calm." It seems to balance my skin so I don't get those random breakouts.Pros:Very lightweight and non-greasy.Doesn't pill under other skincare products or makeup.Visible improvement in skin clarity by morning.Fragrance-free (great for sensitive skin).Cons:Because it absorbs so fast, you have to be quick with your application! I find it works best when applied to slightly damp skinThe Verdict:If you want a simple, effective serum that actually improves your skin texture while you sleep, this is it. It’s great for anyone who wants clear, "glass-like" skin without spending a fortune.
Excellent
If the packaging is accurate this contains PURE Hyuralonic acid. It is rapidly absorbed.
I’ve used Hyaluronic Acid on my face twice a day for three or four years and it’s made an excellent difference in the texture of my skin along will eliminating visible fine line. For years I struggled with adult acne. Not any more it’s gone. One thing I really had been looking for was a non fragrance product. This is perfect.
Feels so good on my face, I recently started my skin care journey and I have been using this twice daily and my skin has never felt so good, it's hydrated and shiny.
This is the best brand of this product I have come across.
Love this stuff! Ive been using it for several months and it's still more than half full! Its helped a lot with my dry spots. I no longer have to worry about cracking under my nose or flaking under my makeup. It doesn't take much to cover the whole face and neck and if you tap it on the skin it drys very quickly without making it feel tight on the skin.The price is great for the quality and quantity of this product. I will definitely buy this again.
Funciona
Holds moisture in and is good combined with a face cream.
I use it every time I get out of the shower it has improved my golfer’s arms.Give it a try.
Got this as a cheaper alternative to the LaRoche Posay B5 serum. I love that one, but wanted to see if there was something a bit cheaper. This came up in a couple dupe reviews. It's the most similar alternative to the LRP serum in how it feels going on. I'm not sure if it hydrates quite as well, but it's close. The only drawback is that it smells terrible! Enough that I wouldn't purchase it again, even at this pricepoint. I've thought about adding a scented oil to it, but not sure if that would alter the formula.
I decided to try the Beauty Box Hyaluronic Acid Serum mainly because of the good reviews, and as someone with dry, sensitive, and acne-prone skin, I’m always careful about ingredients. So far, I do like it, but there are a few things worth mentioning.First — hyaluronic acid works BEST on damp skin. If you apply it on dry skin, it can actually make your skin feel even drier. I always apply this right after washing my face while my skin is still slightly damp, then follow with moisturizer, and it works much better that way.The serum itself feels lighter and a bit thinner compared to other hyaluronic acid serums I’ve tried, but it still layers nicely under moisturizer and makeup. It also has a distinct medical-type scent, which personally made me feel like the product was more trustworthy and ingredient-focused rather than heavily fragranced.Overall, it seems like a decent option, especially if you have sensitive or acne-prone skin and want something simple. Just make sure you’re using it correctly on damp skin for the best results.
tbh, when I decided it was time to start looking for products for a better face-care regimen, I wasn't enthusiastic. I'm allergic to many ingredients used in skin and hair care products, and past experience has shown it requires months of research for me to find a product that's clean enough for my needs. That's the main reason I decided to look for products that contain the main, essential ingredients I was looking for, like HLA.When I found this product only had 3 ingredients, Distilled Water, Hyaluronic Acid, and Benzylalcohol-DHA, I decided to give it a tentative try. I was relieved when I tested it every other day for the first week and didn't react to it, even more relieved when I used it 4 consecutive days the 2nd week without a reaction!This has become the main ingredient in my face care routine! It's thin, lightweight, spreads quickly and easily, and absorbs within a minute by itself. It also mixes with other skin care serums and lotions well, so it's easy to customize my skin care regimen to my needs. I appreciate that it doesn't block pores, so my skin can sweat as it needs to without my ending up with "stuff" running into my eyes.Since adding this to my skin care regimen, I've noticed better texture, more plumpness, and more even tone. I've also noticed how those facial features worsen if I get in a rush and don't use this product for a few days during the week... 0.0 I'll definitely keep purchasing as long as the product's ingredients don't change!
I'm older. My skin is changing. Wrinkles, bags and dry skin. Oh yes, they're freakin' happening. Hyaluronic Acid sounded like it might be one of the answers I was looking for. It seemed to be in everything that was coming out in 2019 but I don't really like to buy products with a boatload of ingredients I don't need. I like to give my skin what it needs on any given day and not overload it with duplicated ingredients or unneeded ones.So that led me to trying to figure out how you use hyaluronic acid in skin care. What does it do, how does it do it, what will affect its performance? And that can be kind of overwhelming, but it basically boils down to this. It needs moisture (I'm talking good ol' water) to work. Or at least access to it. HA's (I don't want to spell it every time) primary function when it comes to skin care is its ability to carry (bind) 1000's of times its weight in water. It's why it's one of the most moisturizing agents known to science. So you think, great I'll just slap it on my face and I'll be good to go. Yeah, not so much.It matters when you put it on, what you put on after it, and the climate where you live. After I clean my face & do my wash-off GA peel, the FIRST serum I reach for is the hyaluronic acid. (This is the night time routine. Putting this on in a dry climate during the day will DRY you out.) I don't spread it all over my face. I put 2-3 drops in the palm of my hand, and with a finger I tap it into the areas I want to target with it. For me, that's under my eyes, my eyelids and around my mouth and ON my lips. Be careful around the eye area. I don't take it up right under the eye or close to the eye on the lid area. I don't rub it in my eye area either, just to be safe. I always tap, placing it in the area farthest from the eye first and tapping toward the eye. I've never gotten any in my eye, so I don't know if it stings or not. HA is an ingredient that is included in some treatments for the eyes, so I imagine it's probably safe.....but I'm not a doctor or a chemist so.....yeah, use good judgement on your own body? Anyway, it also comes in a pill form to be taken as a supplement (it is naturally occurring in the human body) so I don't have a problem using it on my lips and mouth area. I've got fine lines there that need plumping. After that I continue with the rest of my serums & moisturizer.There are a few things you can't do if you're living in a dry climate and one thing YOU MUST DO in order for this to work. Avoid putting any products on your face that are occlusive, meaning anything that basically seals your face. Think oils or heavy moisturizing creams that some people use to lock in the products so they have the best chance at absorbing into the skin. This creates a barrier that defeats the purpose of using HA. It needs access to moisture, and if it can't get it, it will take it from the closest possible place.....your skin. Which is why some people say it dries their face out. So you're probably wondering how it's going to possibly work in a dry climate? As I said, it's part of my night routine and it's what I do right before I go to bed. On my bedside table I have a humidifier (mine has a spout on it that allows me to control the direction) that blows a cool mist over my head all night. Anyone who's living in a dry climate should do this for their skin, whether you're using HA or not. It's the absolute best thing I've ever done for my skin. In the lip area, I still use a sleeping mask over the HA some nights, I just make sure it's not something that's got a heavy occlusive oil in it. You can google the ingredients in the product to find out if they're a barrier to moisture or not. There is no scent to HA, it's a safe ingredient to use in skin care, it does amazing things for your skin, and ANYONE can use it.....it just might require a few tweaks depending on where you live.
I'm in my late 20s and I want to delay wrinkles and other signs of aging before they show up. I've researched a lot and found out that delaying the signs of aging and preventing them is the way to go to stay "youthful" as long as possible. And in fact, people should start taking care of their skin in their 20s because it's easier to keep a smooth, wrinkle free skin rather than trying to erase or hide wrinkles and other imperfections.I started using this product about two months or so ago when I saw lines around my eyes and on my forehead. I see a lot of my peers who are still in their 20s, but look like they're in their 30s and 40s. They look tired and have lines all over their faces that weren't there before. First off, I've tried to consciously stay out of the sun if I could help it. I use sunblock if I can't avoid the sun. My peers didn't really care for that when we were younger and the sun damage on their skin is obvious. Their skin looks dry, cracked, tan but old. I say this because if you want the best benefit from using this product, you should try to stay out of the sun and use sunblock if you can't.Also, this product works really well with a moisturizer. I apply this product first on clean skin and let it dry for a minute. Then I apply Neutrogena Rapid Wrinkle Repair for Night because it's a moisturizer and also has retinol, which really helps with skin repair (wrinkles and uneven tone), smooths skin by promoting new growth, and also helps keeps my skin clear from acne. Once a week, I do a 1 minute glycolic peel (30%) then rinse off and apply hylauronic acid and just a simple moisturizer on top. I skip retinol products that night because it will burn/sting the newly treated skin. Also skip anything that would sting if you are somehow still using any other products like salicylic acid, etc. The glycolic peel makes a huge difference. I could tell the first time I used it that my skin was softer, smoother, more even toned, and just feels better. Read up about it for sure before using it because it can be strong. It's supposed to help peel away dead skin and stimulate new smooth skin. It seems to do that for me.But these products I'm talking about like retinol and glycolic peel will make your skin sensitive to the sun and will easily make you burn. So, definitely stay out of the sun if you can help it, use sunblock, a hat, and whatever else you can do to avoid sun exposure. Otherwise, your skin won't look great and it will all be for nothing. But if you take care of your skin consistently and follow directions well, you will see a big difference. It's like exercise. You have to do it everyday, but you won't see a big difference until after some time. I wish I took pictures of my skin before I started my regimen. I'd really love to show what has changed for me.Also, I recently got married and was showing people my wedding photos. A lot of people assumed I was the "baby" in my family. Just looking at photos, they thought I was the youngest out of all my sisters (also my bridesmaids). I am 7 years older than one of my sisters and 10 years older than the youngest. People were blown away and actually felt bad for my sisters. And I can still hang out with my siblings and their friends if I need to. Their friends also mistake me as someone closer to their age and wouldn't believe I'm much older than they are.
I just ordered this here because of the price. I've used this product before and really like it. If you want to reduce the appearance of lines and wrinkles, this will do it. It hydrates the top layers of your skin and plumps them up so your lines get smoothed out. Works brilliantly for that. It does dry your skin if you use too much, so go easy with it. I also had skin irritation when I used too much, slight burning and redness. But with the right moisturizer, this isn't a problem. I also want permanent change in my skin, so I have experimented with a whole lot of products and now have a great, affordable anti-aging skin care regimen.First, I beg to differ with the other commenters here that you can't reduce lines and wrinkles. Yes you can. It's more difficult if you are addicted to sun or cigarettes - they are the worst for your skin (alcohol isn't great either), but I had deep crevices on my forehead, heavy lines around my eyes and lips and they are gone. Not anymore. In addition to this product (this is the best hyaluronic acid product), I made a daily ritual of a retinol cream at night - best results were from RoC Retinol Correxion Deep Wrinkle Night Cream, 1 Ounce - this product in the morning, and morning and night I use my all time, never live without, the one thing I would pack for a desert island, Bel Essence All-Natural Anti-Wrinkle Treatment - Intensive Anti Aging, Facial Lift Skin Care Formula - 1.5oz. The retinol helps your skin turn over faster so that helps eliminates lines and wrinkles. The hyaluronic acid plumps up your skin so they aren't as noticeable, and the bel essence gives your skin the vitamins, fatty acids, omega 3's and 6's that are needed to build healthy new skin, minus the lines, wrinkles and dark spots. The bel essence also relieves the harshness of using retinol and hyaluronic acid, especially if you have dry to sensitive skin like me. I was shocked that an all natural product could erase wrinkles, but the bel essence is fabulous and even when I stop using the Roc for a while, the bel essence keeps working on the lines and dark spots. Only product I have ever used that gave consistent and permanent results. Add weekly exfoliating (I use a clay mask), and my skin is now, after a year, so smooth, soft, and skin tone is so great, that the only make up I wear is blush and mascara. I started seeing some instant results, the bel essence and hyaluronic acid hydrated my skin immediately and made it look good, but after a couple of months, I was seeing permanent change. I use the same regimen on my neck and hands, and I get compliments all the time about how young I look, how soft my skin is and that I have a glow to my skin. The lines on my neck are gone, and my hands don't look like old lady crepe skin. I look better than I did 10 years ago. The right combination of products makes all the difference.
This is an in-depth review of this serum, which I use in my 5-Step Japanese Skincare Routine. This is the third step in the process, with the order being: cleanser, toner, serum, eye cream, face cream. I have never used a serum before and was initially intimidated by the word "acid" and the fact that it came in a medicinal looking dropper bottle. But so far I have really enjoyed this addition to my daily skincare routine. Not only do I have combination skin due to my Japanese-American genetics, but I'm also allergic to everything and live in both dry, cold Colorado and hot, humid Georgia. I've been hunting a whole set of products to create the ultimate skincare package. We all have hyaluronic acid in our bodies already, but is generally taken as a supplement to help with joints. Instead of injecting this into my knees, I'm patting it all over my face to help with dry skin. It's supposed to be great for people with eczema or skin problems. I'm using it to help prevent signs of aging, and to improve my combination skin and overall skin tone.PROS:- gentle on sensitive skin (I didn't have a horrible reaction)- helps trap moisture in your skin after your clean and use a toner- can mix it with other nighttime serums- has an initially oily texture that quickly absorbs into skin in dry weather (instant moisture relief!)- has helped with my poor dry hands- evens out skin tone- some lightening affects (or it has relieved my skin of any existing redness?)- no acne or blemishes formed- comes in a handy glass bottle with a rubber dropper- no dye, just a natural clear liquidCONS:- a bit expensive, and lasts maybe a month or so if you're using it generously- takes a while to soak in (you have to keep patting your face with your palms into it absorbs)- a bit tacky in humidity (not to bad if you use it after a shower at night, but in mornings it might affect your makeup)- takes a while to see a difference, especially if you're not applying it evenly- doesn't contain vitamin c, which is supposed to help you absorb/process it better- if you spill any, it's a pain to clean out of clothingOVERALL:I love what hyaluronic acid does for my skin. It really helps to lock in moisture and works well once you get the hang of patting it evenly into your skin. However, it is a bit pricey, which is why I knocked it down a star. But I will buy it again, though perhaps one that includes Vitamin C to help my skin absorb and process the acid more efficiently. There are apparently no studies that prove hyaluronic acid works. I see subtle differences in my skin tone, but not my pores, wrinkles, or tightness of skin. I believe this serum could be used for everyday maintenance, aging prevention in skin, and overall brightness and clarity. But if you're looking to reverse skin aging, wrinkles, or loose skin then you'll need to mix this serum in with another cream that does the trick. Think of this as a booster to your existing skincare routine.
