Don't love the consistency
If you do add more than one layer, it gets pretty sticky/tacky, so layering on more moisturizer and SPF can get tricky--particularly if you plan on putting on makeup. I also think that there are better products out there for discoloration.

Discoloration serum review
[This review was collected as part of a promotion.] I have problems with hyperpigmentation and was happy to find this serum. I have been using the serum for about two weeks and feel like it’s working already. I hope I can see more results using it long-term.

Effective and Gentle!
I don't use this on my face. I actually use it on my abdomen to fade discoloration of surgical scars. It has a nice light texture and doesn't feel sticky. I use it every day in the morning and at night I apply retinol. The combination of the two products has really done a nice job at lightening the discoloration of my scars. I also love that there are multiple active ingredients for fading discoloration so it's a great all in one serum!

Amazing but start slow
I have been using this since May and I will say its nice to have a product that addresses all sides of hyperpigmentation especially for black people. Very well formulated and a huge bottle. I use it 4x a week once a day. I have reactive super sensitive acne prone skin and eczema so I definitely purged. I started off slow 1x a week for 2 weeks the went up from there. You have to be serious about using sunscreen and a hat. Any serum will take a while to work nothing is magic in a bottle but if youre patient its worth it for older marks. New marks barely leave a mark and goes away fast. I combined mine with microneedling and my skin looks wayyyy different.

Doesn't make any change
I finished the whole bottle but didn't notice any change for my darkspot. Good thing is I didn't breakout.
