I bought this serum last year when the pandemic hit, because my skin would break out a lot. I had maskne and a lot of dark spots. Then I began to use this product. I loved the smell (it’s citrusy) and how easy it is to apply, it doesn’t leave the skin sticky and doesn’t cause any more break outs, which is fantastic in itself. I started to see a difference on my skin about a month into using it, because my skin looked dewy and a lot of the dark spots I had for literally YEARS were so much smaller or completely gone. This is why I highly recommend this product for Acneprone skin types and anyone who has dark spots.
