Refresh AHA BHA Vitamin C Booster Serum

The COSRX Vitamin C Booster Serum has been a game-changer for my skincare routine. Its lightweight formula absorbs quickly, leaving my skin feeling refreshed and radiant. I've noticed a visible improvement in my skin tone and a reduction in dark spots. The serum is gentle and hasn't caused any irritation. While the packaging is simple, the product itself delivers impressive results. A must-try for anyone looking to brighten their complexion and achieve a more even skin tone.

An excellent serum has helped in reducing darks spots and smoothing out skin texture. The consistency is watery but the ingredients are effective. It seems a small amount but lasts a while you only need a little as it’s so watery it spreads quite evenly. It is fragrance free so there is no scent and it doesn’t cause irritation. I use it at night as it is an AHA. It’s gentle on your skin so good for sensitive skin.

This product is from good quality. The size of the package is smaller then a hand. The smell is good, and have no scent. It’s a good care for your skin, and has benefit in protection from sun if you apply a sunscreen the morning after using it. The frequency of use- every day in my evening routine. I have a sensitive skin and it’s gentle enough for me. The ingredients in the product are good for anti aging and the absorption into skin is really fast

The composition is very good. The scent is not strong and very gentle upon application. Easily absorbed into the skin and leaves no sticky residues. It can benefit not only people who have acne-prone skin but also those with sensitive skin with acnes. The price at iHerb makes it an affordable product with high quality ingredients. The packaging is non-tinted glass bottle, and the dropper is of high quality. I love keeping it in the fridge, and when I use it, it's very soothing to the touch!
i love korean skincare vitamin c serum, its a little bit expensive than i usually bought "western" cheaper vitamin c serum. its clear water visually and little bit thicker in texture but the most impressive to me is that the serum doesnt gunk up when you apply it with other skincare on your skin unlike a cheaper western product with to much silicon in it to make the serum thicker.packaging is very nice, no strong scent which i hate when they put perfume in any skincare. its not very strong this is good for sensitive skin.
I love this booster. When I use it I notice that the spots on my face fade and my skin looks visibly smoother. I was in the store recently and some random dude caught a glance at me and said “you got good skin!!” He looked surprised and then just walked away. That made me feel so good because I still battle hormonal acne, but these products have evened the playing field. It’s so much more manageable and my skin is so much smoother.
Purchased for fine lines on my forehead. Recommend product. *Definitely Do Your Research For Your Skin Type* RECOMMEND SELLER! EXCELLENT COMMUNICATION. FAST SHIPPING AND PACKAGING ON POINT
I LOVE all COSRX creams and toners, work great for my skin, and decrease wrinkles, I love light texture, this serum I use it in evening mostly, following with cosrx sunblock (which is new on iherb). Perfect quality, good package. Great for hot season and winter time. Amazing moisturizer, feel good all day. At night I use hyaluronic cream
