I've been using glycolic acid for years and it has been wonderful. I only use a cheap one (superdrug) and it has helped significantly with the tone of my skin.
I'm going through some...hormonal changes...and recently I'm finding that despite using it regularly my skin is more prone to spots and fine lines.
I'm wondering whether I need to change my skincare routine but have no idea what to try next.
Would welcome your ideas oh wise women of MN.
