What is activated charcoal in skincare?
Activated charcoal is carbon – usually from coconut shells, bamboo or wood – that has been heated and treated to riddle it with microscopic pores. That processing gives a single gram an enormous internal surface area, which is what makes it such an effective adsorbent.
It binds molecules to its surface rather than absorbing them into itself. In medicine this is genuinely powerful: activated charcoal is given orally in poisoning cases precisely because it traps toxins so efficiently.
What skin concerns does activated charcoal treat?
On skin the claims outrun the evidence. It sits on the surface and can lift some oil and surface grime, which suits oily and congested skin, and it gives cleansers and masks their visual appeal.
What it does not do is draw impurities out of pores or detoxify skin – charcoal cannot reach inside a follicle, and skin does not hold toxins that need extracting. Peel-off charcoal masks are worth avoiding outright: they remove vellus hair and surface skin along with the plug, and irritate more than they clear.
What ingredients are best paired with activated charcoal?
In a wash-off mask it works best alongside clay – kaolin or bentonite – which genuinely absorbs sebum, plus soothing ingredients like colloidal oatmeal or aloe to offset the dryness.
For the results people buy charcoal for, salicylic acid and niacinamide do far more: one clears inside the pore, the other regulates oil at source. Treat charcoal as a pleasant weekly cleanse rather than a treatment. Take our Skin Quiz.
What is melasma?
Melasma is a common form of acquired hyperpigmentation that appears as symmetrical brown or greyish-brown patches, most often across the cheeks, forehead, upper lip and jawline. It develops when melanocytes – the pigment-producing cells in the skin – become overactive and deposit excess melanin into the epidermis, the dermis, or both.
It is far more common in women and in medium to deeper skin tones, and it behaves as a chronic, relapsing condition rather than a one-off mark – which is why management matters as much as treatment.
What causes melasma?
Three triggers dominate: ultraviolet and visible light exposure, hormonal change (pregnancy, oral contraceptives and hormone therapy – hence its nickname, the mask of pregnancy), and genetic predisposition.
Heat, visible light from sunlight and screens, inflammation from harsh products or aggressive procedures, and certain medications all make existing patches worse. Because the triggers are ongoing, melasma typically fades and returns rather than clearing permanently.
What ingredients are best for melasma?
Daily broad-spectrum sunscreen is non-negotiable, and a tinted mineral SPF containing iron oxides is best because it also screens the visible light that drives pigment production.
On top of that, the most evidence-backed actives are tranexamic acid, azelaic acid, niacinamide, vitamin C, alpha arbutin, kojic acid, liquorice root extract, retinoids and gentle alpha-hydroxy acids. Avoid harsh scrubs and strong heat, both of which can rebound the pigment. Take our Skin Quiz to build a routine around your skin tone and triggers.
