Extract of the green single-cell alga Chlorella vulgaris. Contains chlorophylls, carotenoids, peptides, and beta-glucan. Marketing promotes it as a detox/anti-pollution active, but clinical skin evidence is limited – most data come from in-vitro studies. Pregnancy-safe.
Topical application
DVery weak or conflicting data.
Antioxidant activity is documented in vitro; controlled human skin trials are scarce. Detox and anti-pollution claims are weakly supported. Traffic light YELLOW – a niche ingredient with overstated reputation.
Chlorella vulgaris is a single-cell green microalga of the Chlorellaceae family. It is known as a nutraceutical and food supplement thanks to its very high content of chlorophyll, carotenoids, protein (40-60%), and B-group vitamins. In cosmetics it is used as an aqueous or glycolic extract of enzymatically lysed cells. INCI: Chlorella Vulgaris Extract. Marketed cosmetic effects. Manufacturers promote the extract as: • antioxidant (chlorophylls, carotenoids); • anti-pollution (binds heavy metals); • skin detox (absorbs toxins); • collagen synthesis stimulator (via peptide fractions). Actual evidence. In fibroblast and keratinocyte cultures, chlorella extract shows antioxidant activity and stimulates collagen I/III synthesis. However, controlled human skin trials are scarce – most published RCTs concern oral chlorella for metabolic outcomes, not topical cosmetic use. The claimed skin-detox effect is mechanistically unconvincing: there is no evidence that topical chlorophyll can pull dust or PM2.5 out of the skin. Pregnancy safety. Topical use is safe. Systemic absorption through intact skin is minimal. Oral chlorella during pregnancy is controversial (potential anticoagulant interactions, theoretical immune-activation risk), but this does not apply to cosmetic use of the extract. Skin tolerance. Low irritation and allergen profile. Non-comedogenic. Suitable for most skin types. The dark green tint can color a formula – manufacturers typically work with a decolorized fraction.
