- Reviewed in the United States on April 5, 2025Color: Vitamin 23% Peptide SetVerified PurchaseI am almost 54 years old. As a child I had many sunburns with bubbles and the skin of my chest had always had creases wrinkles, freckles and sun damage. Not pretty. Always rough to the touch. Recently I noticed something popping up that looks like a melanoma. So I took a paste of L ascorbic acid and gave myself a chemical burn.
Unintentionally. After the burn healed, the skin on my chest had improved, buy had a rough texture. Because L Asciorbic acid is associated with fighting melanoma, I researched Korean, vitamin C, l-ascorbic acid skin care. And this product appeared. No other product (and let me tell you I have hundreds of items I’ve spent over $100) has repaired my skin as effectively as this one in a short period of time. It has returned the brightness that I had from youth, it has softened the skin on my chest. It’s removing sun damage and fine lines. The only problem with this product is the vitamin C smells very bad. Like urine or dog food. If you want your skin to glow and you want to fight aging while also combating melanoma, this product is for you.
One last thing, the vitamin C vile ingredient list is not in English. They need to correct this.

Reviewed in the United States on April 22, 2025Color: Vitamin 23% Peptide SetVerified PurchaseEl suero peptide realmente no he visto mucha diferencia, por otro lado vitamina C da muy buena hidratación a mi piel seca y sirve para piel sensible, es aceite pero se absorbe fácilmente y no es grasosa me gusta mucho.
- Reviewed in the United States on March 10, 2025Color: Vitamin 23% Peptide SetVerified PurchaseI’ve used both the vit c and peptide serum for about 5 weeks now.
I’ve tried lots of low cost products before (many products from the ordinary etc) but haven’t seen much difference.
These definitely made a difference - way more radiant skin, more even tone and texture, less sebum, more hydrated.
I did use it with a red light panel (hooga) I was trying for the first time too, so that may have also helped.
I definitely used a lot - 5-6 pumps peptide first followed by 5-6 drops vit c, twice a day, both morning and night, followed by moisturizer. I don’t use any other skin products, except sunblock occasionally.
The vitamin c only lasted abt 5 weeks (I just repurchased)
The peptide bottle is still at least 2/3 full after 5 weeks.
- Reviewed in the United States on April 17, 2025Color: Vitamin 23% Peptide SetVerified PurchaseI like it, but can be a little bit intense for your sensitive skin, I recommend to use just for two or three days in a week
- Reviewed in the United States on April 15, 2025Color: Snail 96% Peptide SetVerified PurchaseI don't know whether or not this works, but if it's what my wife wants to try - why not? She does have youthful looking skin though :)

- Reviewed in the United States on April 2, 2025Color: Snail 96% Peptide SetVerified PurchaseIncredible skin care. I am a 70 yr old who does take care of her skin. Been using Trentinoin cream for 10 years and I thought my skin looked good...until I tried this snail mucin and it took my skin to the next level. It was not expensive and it works with my other skin care products...highly recommend.
