Great starter Vit C product. Would highly recommend for beginners as it's a derivative and not direct -> less irritation and interactions with other acids. Repurchased multiple times.

the best affordable vitamin c serum u can get, period. u see ACTUAL improvement in ur hyperpigmentation, no fragrance, no oily residue, absorbs quickly, has a water like texture, save for every skin type, should i say more?
Great price, great ingredients, fresh. I notice the effects in my skin. Big but not for sensitive skin. I am an stubborn girl so I made it work. For a long time my morning routine was this and a lot of Centella and oat and hidrating essences just to stop my skin from reacting. Now I can use it without worrying but I need a calming essence immediately after it.
