This works as well as hydroquinone has for me without any irritation. It took about 6-8 wks to lighten my pigmentation (freckles/ sunspots, not melisma) but once it did it was significant. I will add that I’ve been using retinol/ retin a products for years so I’m sure that helped as far as tolerance goes. Will definitely repurchase!
I’m very impressed with this product! I’m still adjusting how often I should use per week due to some sensitivity, but the results have been excellent thus far.
