Great bottle with nice pump, doesn't leave skin too sticky, evens out skin tone effectively!
Earlier this year, I used this product in conjunction with a salicylic acid cleanser, benzoyl peroxide spot treatment, and patchy sunscreen application, then proceeded to get frustrated about why this serum seemed to make my breakouts worse! So glad I've learned about and researched Vitamin C since then - I picked up this serum again recently and have actually started to see it work its magic (since I now apply it consistently once per day and without other strong actives, and follow it with a hydrating SPF moisturiser). I'm currently layering it with a niacinamide serum, which hasn't been an issue yet, although I've noticed people online tend to be on the fence about this combo - in any case I think the best rule is listen to your skin and do your own research :)
This is one of my favourite vitamin C serums for hyperpigmentation. The dark spots and acne scars on my face have faded over time. Be sure to use a good sunscreen over the serum so the efficacy of the vitamin C doesn't deteriorate.
This is a lightweight brightening serum that brightens and hydrate the skin when use twice daily. Love it.
