Lactic acid – always the bridesmaid for the more hyped glycolic acid – is my first choice of alpha hydroxy acid for all manner of reasons. It exfoliates without stripping or stinging (its bigger molecule size makes it particularly well tolerated by even sensitive skins), can stimulate collagen and ceramide production to firm, plump and protect mature skins, has antibacterial properties for more problematic ones, and binds with water to keep every type more hydrated. Lactic also imparts an unmistakable glow to the complexion and deflakes rough areas brilliantly.
I’ve always loved it, but have rarely been so spoilt for choice. Beauty Pie’s new Youthbomb Extreme Retinal Triple Renewal Serum (£49 to members) is their best formula in some time, which goes some way to justify its high (for Beauty Pie) price point.
