VICHYRadiance Duo, Skin Care Set with LiftActiv 16% Vitamin C Serum & LiftActiv B3 Niacinamide Serum, Gift Set for Brightening, Dark Spots & Wrinkles

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.

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

Very lightweight, definitely has helped my skin with brightness. I love that you mix it unlike other brands. Doesnt have a scent to me and very absorbent. Overall it my go too vitamin C serum

Okay I have bought this product three time. Usually lasts me about three months with consistent use (once a day in the morning after washing my face). One thing I will say is that I think the potency goes down after about a month (month and a half). I definitely notice the liquid turning a bit more amber and the smell fading. I love the product but I think because it’s vitamin c the amount though appreciated ends up not being as effective for how long you can use it.

This serum is like my morning’s ABC.. tradition. I can’t exist without it!It brightens my skin and has a great impact on my facial skin vigor.

Terrible Experience – Caused Irritation and BreakoutsI had a very disappointing experience with this product. Shortly after using it, my skin broke out badly and developed red marks and irritation that took days to calm down. I followed the directions exactly and didn’t use anything else new in my routine, so I’m confident this product was the cause. I would not recommend it for sensitive or acne prone skin. Very frustrating and not worth the risk.

Watery consistency makes it hard to apply, and it's a sensory nightmare of stickiness and pilling on the skin. I really dislike this

Good quality, vitamin C face serum that is not too sticky and absorbs very well into the skin. I use it in the morning and it soaks in very smoothly and nice.
