TL/DR: great price for the clinically validated quality, I see no validity in complaints, follow-up with moisturizer after 1 minute to entirely eliminate residual (minor!) tackiness, AWESOME for healing scars.I've been using this on surgery scars. In October 2023, I had surgery on my scalp. The surgery itself went well, but the aftercare I received was *awful*. I ended up with several truly atrocious scars that were —lobster— red. My PCP recommended vitamin C serum to remove the redness and help with the healing process, as it would also boost collagen production. My skin tone has dramatically improved!! Thanks to this serum, you have to reeeally know where to look to see my scalp scars, rather than them being visible from across the room!So I HAPPILY purchased this again for my hysterectomy scars as soon as it was safe to apply it. (Do not apply to broken skin!) The rich blood supply to the scalp makes healing occur fairly quickly (if you're getting proper care). The pigmentation correction on my hysterectomy scars is taking a little longer given their location. I can't believe it took me so long to consider it. But I also have a very prominent red scar on my wrist from a type of benign growth that was removed. That scar is still the most pigmented, but it's THE BEST it's looked in MANY years. It's seemed to help with flattening the scar, too?? CAVEAT: I don't know if vitamin C is capable of flattening scars; it may be a coincidence. It also reduces blemish redness when I get an acne flare. I'm REALLY happy with my results for each use.I purchased this the first time after failed attempts at finding a high quality, high percentage vitamin C serum that didn't dry on like sticky, thick, and gooey egg-like film that never absorbed. Vichy's serum had come across my Amazon suggestions a number of times while I was experimenting with cheaper (and inferior) products. The price tag of Vichy "seemed" high, so I avoided buying it for a couple months. But I got tired of looking like I had dried egg whites in my hair and gave this a try. I learned this is in the price range you can expect to pay for true quality. I think it is very competitively priced for its caliber.Yes, you can buy cheaper vitamin C serums, but you get what you pay for. The cheap ones are gooey and never absorb into your skin, don't have the same high percentage of vitamin C (some are obviously so low they don't even disclose the percentage), and are very diluted with a needlessly and extremely long list of ingredients. This ingredient list is modest and very well-appointed, with true therapeutic levels of the ingredients, all of which are clinically researched to be effective.Many clinical studies indicate that the best range for vitamin C topicals is 10-20%, with no significant effectiveness above 20%. So the Vichy vitamin C serum at 15-16% (I've been purchasing it since it was originally 15% and now it is 16%) is the perfect therapeutic range.For those complaining about tackiness on the skin... It's vitamin C y'all!! :-/ A tiny bit of tackiness is to be expected! Don't dump it on! Wait 1 minute after patting it on for it to seep into the skin, and follow-up with your favorite moisturizer. The -mildly- tacky skin feel disappears ENTIRELY after moisturizer is applied. I also feel that it boosts the hydration of my moisturizer.I really have -no- idea why some people are complaining about the applicator top. The applicator base screws on and fits snuggly. It's extremely effective at controlling the flow of product, which allows for easy application. The tiny screw off cap on the applicator tip doesn't leak.

Vichy is an amazing line, I have used several of their products. This vitiman c is excellent. 16% vitamin c really helps with skin discolorations and brights .makes my skin glowy. Esthestician recommended.

I hadn’t tried Vichy product until this serum and I’m finding myself to be pleased with my purchase. It’s an ultra light liquid formula and absorbs easily into my skin. This formula has no scent, which I like as so many Vitamin C serums out there are scented and not always pleasantly. My complexion appears to be fairly luminous and healthy since beginning use of this serum. Application doesn’t sting, or feel harsh on my face. I do feel slight tingles when applying my moisturizer over it, nothing unpleasant, tells me it is effective serum really. Looking forward to continued use.

I’ve been using this for more than 4 months. It worked great starting out. After a while, it’s not working as great. Probably not suitable for my skin, but the product works.

I love this line of products. I have noticed a change in my skins texture, firmness and brightness. The brown spots on my cheek are fading. I started with the moisture serum and c cream, then came back for the c serum and the meno 5 bi serum. My face feels so clean and fresh after using the products and am definitely seeing a positive change. I also like the dispensing of the product with the twist on cap. I wanted to address the many complaints from people with the C serum. Many say it is not a full bottle and complain thinking they are cheated out of the product or received a used product I wanted to tell any potential purchaser that the c brightness serum is 20 ml in the same size bottle as the meno 5 bi serum which is 30 ml. I’m sure the manufacturer uses the same bottle with different fills to save having many different size bottles You are getting the full amount of 20 ml in the c serum. The products are wonderful

This serum delivers excellent results during the first week after opening, remains moderately effective for another week, but begins to lose stability by the third week. Like most vitamin C formulations packaged in bottles, it oxidizes quickly when exposed to light and air. An airless pump would significantly extend its shelf life and preserve potency—something many major brands still surprisingly overlook.By week three or four, the serum typically turns a darker orange. This color shift signals oxidation: as ascorbic acid breaks down, it loses antioxidant effectiveness and can temporarily stain the skin with an orange tint. This effect usually fades within a day or two, but it’s a clear indicator the product is no longer delivering the intended benefits.Until this serum is reformulated with better packaging, I’ll be relying on options that come in airtight or airless containers to maintain true vitamin C efficacy.
