Oily skin and enlarged pores: getting a refined texture back
Shine by midday, visible pores, blemishes: combination to oily skin calls for a methodical approach — exfoliate wisely, regulate without stripping. The Belweder routine.
The classic mistake: stripping the skin
Faced with shine, the reflex is to dry the skin out — detergent cleansers, alcohol, abrasive scrubs. It’s counterproductive: under attack, the skin compensates by producing more sebum, and a vicious circle sets in. Modern dermatology prefers regulation to stripping, with two complementary families of actives. Exfoliating acids first: salicylic acid (BHA), being oil-soluble, is the only one able to penetrate the pore and unclog it from the inside — it’s the benchmark active against blackheads and shine; mandelic acid (AHA), with its larger and therefore gentler molecule, smooths the skin texture on the surface without irritating, ideal for alternating or for sensitive skin. Niacinamide (vitamin B3) next: it regulates sebum production, visibly tightens pores and strengthens the barrier — the ally that lets you exfoliate without weakening the skin. The key is to go step by step: introduce the acids two to three evenings a week, observe, then increase. And never forget that even oily skin needs hydration — water, not oil.
