Honest reviews

This irritated my skin badly..Dry and Itchy

I hope I don’t receive the backlash for my review like some other "low" star reviewers have. I am NOT a competitor, DO NOT sell Vitamin C serums or work for any company that does. This is an honest review for the product, not the seller (they seem to provide excellent customer service). I do feel compelled to leave my review however, even if not great because of the experience I had. I use reviews frequently when purchasing products and hope that mine will help others.I was excited to try this product as before I purchased it I researched the full ingredients (listed in the questions area) and it seems like all the ingredients are excellent for skin care and signs of aging. This is a thicker serum than others I have tried, has a bit of a smell (not really unpleasant) and comes in a bottle with a dropper.Day 1: When I first applied the serum, I felt an unpleasant stinging (which I think they say means its working) so I went through this unpleasant experience (even though it only lasted a couple of minutes). But then my cheeks, forehead and neck got bright red. I thought "ok, its just penetrating into my skin and will go away". Some of the redness on my cheeks did subside after applying my moisturizer, but not on my neck or forehead. I had a red rash there all day. And it only got worse as the day went on. My skin felt dry and irritated all day and I mean dry like PARCHED! My makeup looked like it was "sitting on my face" not blended and natural like usual. My face was so itchy and my eyes watered all day long, I felt like I wanted to scratch my face off! I did NOT apply this product under my eyes (I’ve learned the hard way not to do that with a new product) so I just used it on my face and neck. I did not change my skin care routine in any way except for changing from my other Vitamin C serum to use this one.Day 3: (skipped Day 2 because I read to use the product every other day if you experience irritation). Applied the serum after cleansing, here comes the unpleasant stinging feeling again. At this point, I thought to myself, why am I putting something on my face that feels so bad? Come on skin, adjust and let this work! Nope, red cheeks, forehead & neck again, moisturize, subsides a bit. Again, dry and itchy all day. What was more worrisome, is when I looked in the mirror later in the day my face looked kinda grayish and my pores and some lines under my eyes looked so pronounced (still did not use this product under my eyes). WTH? Luckily I was home that day as I would have been embarrassed to be in public, but was a bit shocked & worried as to why my face looked so bad with such discoloration.Day 5: (again skipping a day). Same routine, same irritation. Not sure why I’m doing this.Day 6: (Actually night.) I decided I wasn’t going to use this in my morning routine anymore, but thought I would use it instead in my nightly skin care. (wash face, serum, moisturize). Again stinging and redness. Woke up in the middle of the night and had to wash my face over and over trying to get it off because I couldn’t sleep due to the itchiness.Day 7: Back to my other tried and true serum. No stinging, no redness, NO ITCHING! Hydrated all day, skin thanks me 🙂 (And I can apply that one under my eyes (which is where many of us need to for fine lines))I only used this product once a day (whether morning or night) and I only used the product 4 times as I simply couldn’t use it anymore. I did return them in a week (purchased 2, one for me & one for my mom, but did not give one to my mom after the experience I had). I did receive my refund immediately though, so I am happy about that. Just want to add that this is the 3rd Vitamin C serum I have tried, and I am sticking with the one that has provided results ,does not irritate my skin and I can use twice a day. I had only tried this one as I had read that L-Ascorbic Acid is suppose to be the best for skin results, however I am seeing results with the Sodium ascorbyl phosphate serum and I will stick with that one. FYI, I am in my mid-40s, have combination skin, have never had acne (occasional pimple before using Vitamin C serums), no sensitive skin or other issues. I do believe that some products work for some and don’t for others, so if this one doesn’t work for you, don’t give up. If it does work for you, then fantastic! Personally, I have had results with another brand.

OUI Vitamin C Serum with E and Hyaluronic Acid

I’ve used this product every night with a firming moisturizer over it for about 2 weeks now and cannot tell any difference in my appearance of wrinkles / fine lines, tightness of the skin, nor the slightest disappearance or fading of some of my sun spots, as QUI proclaims it will do. Maybe I need to use it longer, but I’m surely not going to order an additional supply, even at a discount, as they are pressuring me to do, until this bottle is gone and I see some better results. The serum is a very thin liquid and hard to apply – it feels like it is watered down. I’ve been using Neutrogena Rapid Wrinkle Repair in combination with the Olay Pro-X Hydra Firming Cream at night in the past and got better results than with the OUI serum + moisturizer. I am a 73-year old single woman and, in addition to keeping fit, I have always practiced good nutrition and skin care throughout my life, So everybody guesses me as much younger, Naturally, I expect a new product to show a little more drastic results than the proven creams I’ve been using. But OUI does not seem to show any more improvements. Also, the price seems to be almost too reasonable for what it is supposed to do. I think I’ll stick to my previous stuff.

Smells

I’m not fond of this serum. It smells… it’s very watery, so I need to put about a ten drops into my curled palm and try to put it onto my face, then smell it all night. After two weeks of use, I didn’t notice any changes so I stopped using it. It’s just worth the hassle to me.

noticed a difference in one night

I just purchased this product. I used it after i derma-rolled my face. It stings bad but the sensation goes away. The following morning i noticed my face was brighter and soft. Also the active acne and pimples have subsided a little. I gave it 4 stars for now, but I’ll re-review it when i notice a huge difference later. I would recommend it as a normal face serum (not only for after dema-rolling sessions) for daily use.

Loved I but could not use for long …

I loved the ingredients and consistency of this product. What a great formula! Unfortunately I only had a pleasure of using it for a week or so and then dropped the bottle and it broke being the glass, so there went my summer time investment and sun damage reversal … All of the ingredients are powerful antioxidants and this formula is moisturizing without being too heavy or oily

Great product for mature skin

I am 53 years old and have been using for 2 weeks. This product has made the texture of my skin soft and supple. I didn’t have any bad reactions such as tingling or breakout. I plan to continue using the bottle I bought and will buy more. I haven’t noticed any significant changes in my wrinkles or fine lines, but I didn’t expect to after 2+ weeks. I would recommend this product to anyone (male or female). I think the price is fair too.Update:2 additional weeks have passed and I continue to use the product nightly. It’s humid this time of year, and I haven’t needed to use a moisturizer with this product, though I am sure to use a moisturizer when fall/winter returns. My wrinkles and lines are not fine, so I haven’t noticed much improvement in that area yet, but I have noticed that my freckles from the sun have lightened up considerably, and my skin does feel soft and healthy. I have adult acne and this product seems to speed up the healing process. I plan to continue using this product as part of my daily regiment.

great serum and great price

This serum is a winner. My skin loves these three ingredients: E, C and HA. The price was right for such a power-packed serum.It’s nice to have one serum for all three.

I love this product!!

I have tried lots of Vitamin C Serums and this one seems to be the best and for the price you can’t go wrong. I have noticed a difference after a few applications. I ordered it some time ago but didn’t try it until about ten days ago. I shouldn’t have waited. My skin does not feel very moisturized. The lines close to my eyes are diminishing. . A couple of very fine lines are no longer there. The company sent me an email and gave me instructions on the best application which I find very impressive. I will continue to use this product because for the short time I have used it I see unbelievable results. I have used some pricey items in the past but this one does wonders. If anyone is on the fence on this product, don’t be. Give it a try. It is definitely worth it.

Great results

I have been using the product every morning and evening I immediately saw difference in my skin, I am very pleased with the results so far and will continue to use it. I have already purchased another bottle so that I can keep one in my bedroom and one in my bathroom so I don’t forget to use it thank you

I was very pleased with this product

I was very pleased with this product. The shipping was very quick. The packaging is excellent. And unlike many products the instructions are detailed. I have faith that the product is fresh and it is what it is supposed to be. I have no sensitivity to this product. I am even able to use it twice a day. My skin is looking fresh and healthy. I will continue buying this brand.

EXCEPTIONAL PRODUCT!

Adding this product to my facial regime was a great choice. I have been using other Vitamin C products but they do not the added ingredients this one has. I believe this product has helped to improve my skin above & beyond the other products I’m using. I would recommend giving it a try. I have not experienced any sensitivity issues but please note I do not have sensitive skin. I’m in my 60’s and spent most of my years in the sun & this product has truly helped in improving the overall look of my skin.
