20% Vitamin C Serum, 1 fl oz (30 ml)

This product has a really good quality I already used the whole thing and I think my skin benefited a lot from it I applied it every morning It’s gentle and non irritant as my skin can get a bit sensitive Just make sure to use sunscreen along with it

It's one of the best vitamin C serums on iHerb. I put it on clean face before my day/night cream and I like my face with it. It should be kept in the fridge after opening,

I felt this was a great quality serum. Love the high concentration of my favorite type of vitamin C, and also the inclusion of ferulic acid.

This Vitamin C is the best I’ve tried, the strength is perfect and gives a healthy glow. I’ll definitely buy it again and again. I notice the difference gradually. Quality is great, just make sure to keep it away from heat. Scent is mild, easy to use and absorbs quickly. I recommend it, the best for its price.

I’ve been using the Asteri 20% Vitamin C Serum for several weeks, and it has made a noticeable difference in my skin’s brightness and texture. The formula feels light, absorbs fast, and layers well under sunscreen and moisturizer. After consistent use, my complexion looks more even, smoother, and visibly more radiant.Good size and package for 2month use

I have rosacea and dehydrated/dry skin, and Cos de Baha is my go-to vitamin C serum, it is the only one I have tried that reduces redness. It was out of stock, so I tried a couple of other vitamin C products. I bought the Asutra because of the clean and natural ingredients, but I did not like it, it seemed to make my face more red. It also didn't have any brightening or smoothing effects. Maybe it would work better for other skin types, but it was not for me.

Vitamin C Serum has become a staple in my skincare routine and for sensitive skin with gentle touch and composition of and benefits and helps to reduce the appearance of dark spots and uneven skin tone. The serum is lightweight and absorbs quickly, leaving my skin feeling refreshed and hydrated texture and overall radiance since I started using it. Highly recommend for anyone looking to boost their skincare regimen with a powerful antioxidant.

Non irritating formula making it ideal for sensitive reactive skin, no scent, very gentle on the skin, size is more than enough for a good two months I use it morning and night I saw big difference in lightening dark spots within two weeks

I've tried a lot of vitamin C serums, but this one from Asutra is my new favorite. It has a lightweight texture that absorbs quickly and doesn't leave my skin feeling sticky. After a few weeks of use, I've noticed my complexion is brighter and my dark spots have definitely faded. It's a fantastic, effective product that I look forward to using every morning.

Good product. It has 20% Vitamin C. Good for everyday use.
