About this ingredient

Activated Charcoal (Carbo Activatus) is a porous form of carbon with high specific surface (up to 1500 m²/g). Produced by pyrolysis of organic feedstock (coconut shell, wood, peat) followed by activation with steam or chemical reagents. Mechanism. Powerful adsorbent: binds organic molecules, sebum, surface debris, and pigments from the skin surface via van der Waals forces. Acts only on the surface – does not penetrate the epidermis. In the gut, medical use is for poisoning and gas; on skin, the effect is strictly external. Where applied. Cleansing peel-off masks, cleansing foams, soaps for oily and acne-prone skin (1–5%), toothpaste, deodorants. Brands: Origins Clear Improvement, Boscia Luminizing Charcoal, many K-beauty masks; in Spain – Sesderma Charcoal Detox Mask, Mesoestetic Cosmelan Detox. Evidence base. Few RCTs; the main base is that activated charcoal's adsorbent properties have been known since the early 20th century. Skin benefit is limited to the cleansing effect of the mask – there is no real 'detoxification' of the body through the skin (toxins clear via liver and kidneys). The dark color produces a visually dramatic 'dirt on the mask' effect – a psychological bonus. Safety. CIR confirmed safety of activated charcoal in cosmetics. Hypoallergenic, non-irritating, non-comedogenic. No systemic action. Pregnancy and lactation – safe. Acceptable at any stage. Oral activated charcoal in pregnancy is used without restriction for gas. Particularly suitable for. Oily and combination skin, acne-prone, enlarged pores. Charcoal masks 1–2× per week. Not for dry skin or for compromised barrier (atopy, rosacea flare).
