Did a patch test on my arm to see if it works for hyperpigmentation - tried for 3 days (once a day) and my arm had small pimples/ irritation bumps! I never have breakouts on my body.
Don’t know if the concentrations are too potent (even for the body) or the formulation is just bad.

I think this is one of the best serums for hyperpigmentation IF you are a BEGINNER (keep that in mind), I have sensitive skin and I find it very soothing but didn’t see much results.
Also this serum is quite sticky so I recommend you that after you apply it on your face, leave it for 10-15 minutes so your skin can fully absorb the product. Then you can use other products as you wish. Hope it Show more
