Amazing on my hyperpigmentation bought this on a whim so happy I did
Light, non-greasy serum. Helped brighten my skin tone after a few weeks of use. Great for dark spots.
This item is effective but works really slow. I’m on my second bottle and I think I’ll be using more going forward! It’s not sticky and absorbs fast and works very well.
I believe this started working from the first application. My small wrinkles are much less noticeable.
What it does for me: I’ve been using this for a month now as part of a new skin care routine and I find it does brighten my skin and it helps with dark spot correction. I use it under my moisturizing sun-screen in the mornings and evening moisturizer at night. I avoid the eye and mouth area. So far, pretty good. Hopefully with continued use I’ll see improved skin elasticity. As for anti-aging? Well, who knows how this product will achieve that. I live in hope.
