Exfoliating, plumping and hydrating, the best products will leave your skin glowing without costing a fortune

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.

Hydrated skin and some trips to the gym – I’ll be embracing better beauty habits next year

I’m not given to making new year resolutions, but by coincidence I have recently made a number of pledges to adopt better beauty habits. I believe that even someone in this job, who already moisturises and UV protects religiously, can still find areas for improvement.

Once again, I have pledged to drink more (or indeed some) water. After decades of tea dependency, I never find myself thirsty in the way others describe, and so force myself to hydrate only for the sake of my skin (to which it makes a noticeable difference) and well, aliveness. To this end, I’ve bought one of those ridiculously enormous mugs influencers drain several times daily, and hope to make my way through perhaps one by bedtime.
