No longer just for the chemically courageous, today’s formulations are as sophisticated as they are effective, offering a bespoke approach to every skin concern – from dullness and fine lines to acne and pigmentation. Whether you’re craving the glass-skin effect of glycolic acid, the plumping prowess of hyaluronic, or the blemish-busting magic of salicylic, the right acid can supercharge your routine.
But tread wisely: the wrong concentration or a too heavy hand, can lead to irritation and sensitivity. Here, we break down the skincare acids you need in your routine, decoding their benefits plus Lydia, our beauty editor, shares the top picks from her skincare routine:
Salicylic Acid
A go-to for oily and acne-prone skin, salicylic acid (a BHA) penetrates deep into pores, dissolving excess oil and unclogging congestion. It reduces breakouts, blackheads, and whiteheads while soothing inflammation. With antibacterial properties, it combats acne-causing bacteria, refining texture and leaving skin clearer, smoother, and less prone to flare-ups.
LYDIA’S PICK:
Paula’s Choice, Skin Perfecting 2% BHA Liquid Exfoliant, £35
I’ve never found anything to beat this for unclogging pores and tightening them. My teen has just started stealing it too and it’s working wonders on their hormonal breakouts.
Azelaic Acid
A multitasking marvel, azelaic acid is renowned for brightening dull complexions, fading hyperpigmentation, and tackling acne. It has antibacterial and anti-inflammatory properties, making it ideal for sensitive, redness-prone skin, including rosacea. Unlike harsher acids, it gently exfoliates while strengthening the skin barrier, ensuring a luminous glow without irritation.
LYDIA’S PICK:
Naturium, Azelaic Acid 10%, £22
I’ve only just added this into my skincare routine a couple of times a week and the glow shot it has given my dull winter skin is remarkable.
Glycolic Acid
As the smallest alpha-hydroxy acid (AHA), glycolic acid penetrates deeply to exfoliate, increase cell turnover, and stimulate collagen. It smooths fine lines, fades dark spots, and enhances radiance. Perfect for dull, textured skin, it refines pores and improves elasticity – though those with sensitive skin should use it sparingly to avoid irritation.
LYDIA’S PICK:
Kate Somerville, Exfolikate Cleanser, £39
I adore the intensive mask treatment version of this too, but the daily wash with lactic and glycolic acids, paired with a trio of fruit enzymes really helps to dissolve those dead skin cells and leave skin bright, soft but not tight and dry.
Vitamin C (Ascorbic Acid)
A powerhouse antioxidant, Vitamin C brightens skin, evens tone and combats free radical damage from pollution and UV exposure. It boosts collagen, reducing fine lines and enhancing firmness. With consistent use, it can fade dark spots and hyperpigmentation, revealing a lit-from-within glow. Best paired with SPF for maximum skin protection.
LYDIA’S PICK:
Sunday Riley, CEO Afterglow, £60
Another winter skin saviour, the sunshine hue of this lightweight gel-cream from Sunday Riley is so quenching under make-up and wakes my skin up in the morning.
Hyaluronic Acid
A hydration saviour, hyaluronic acid attracts and retains moisture, plumping skin and softening fine lines. It strengthens the skin barrier, ensuring lasting hydration for all skin types. Lightweight yet intensely nourishing, it delivers a dewy, youthful complexion, making it a must-have for both dry and oily skin alike.
LYDIA’S PICK:
Vichy, Mineral 89 Hyaluronic Acid Hydrating Serum, £28
I add two pumps of this mineral-rich hydrating serum to damp skin to really lock in moisture to my dry, wind-chapped skin. It leaves it noticeably dewy and plumper.
