CBD in cosmetics: what the skin does with it and what the law allows

The European Commission's CosIng database is the official inventory of authorised cosmetic ingredients. CBD was listed there in February 2021, under the designations "Cannabidiol" and "Cannabis sativa leaf extract". In 2024, the Commission extended that authorisation to hemp leaves for cosmetic use. The practical consequence: a CBD cosmetic falls under European regulation 1223/2009, and not under the more restrictive regime for food supplements (Novel Food).

The skin is an effective barrier against the penetration of most molecules. CBD, being lipophilic, partially crosses the stratum corneum, with absorption localised in the superficial layers and no significant systemic passage at common cosmetic doses. That is why a topical application does not normally trigger a positive saliva screening for THC. The skin also has its own endocannabinoid system, with CB1 and CB2 receptors present on keratinocytes and cutaneous immune cells, which fuels scientific interest in this ingredient without demonstrating a clinical benefit.

Cosmetic claims are governed by regulation 1223/2009. A CBD cosmetic may present itself as "moisturising", "soothing for sensitive skin" or a "care ritual". It may never, on the other hand, claim an "anti-inflammatory", "healing" or "pain-relieving" effect: such wording would amount to a therapeutic claim, reclassifying the product as a medicine and exposing the brand to penalties from the DGCCRF. In 2024-2025, more than 1,200 inspections found an infringement rate of about 15 %, relating mainly to these non-compliant claims.

Four points deserve checking before purchase. The THC content must stay below the acceptable contamination threshold. The full INCI list must appear on the label, with CBD designated as "Cannabidiol" or as a compliant hemp extract. Potential allergens (limonene, linalool, geraniol) must be listed above certain concentrations. Finally, the absence of cannabinoids banned since June 2024 (HHC, H4CBD, THCP and derivatives, classified as narcotics by the ANSM) must be documented by the seller on request. Our CBD buying guide sets out these criteria for every format.

Can topical CBD make a saliva test positive?

Very unlikely with normal cosmetic use: the skin penetration of CBD is superficial and the systemic passage of THC (present only in traces) remains negligible. Take care in the event of heavy, repeated use over a large area.

Is there a recommended cosmetic dosage?

No European authority has set a threshold. CBD cosmetics on the market range from 0.5 % to 5 % CBD depending on their purpose, with no validated dose-effect relationship for topical uses.

Is CBD effective against eczema or acne?

No European authority recognises such effectiveness, and any claim of this kind is prohibited. Preliminary studies exist on cutaneous inflammatory pathways, but they remain insufficient. Consult a dermatologist if you have a condition.

Can pregnant women use a CBD cosmetic?

The precautionary principle applies: in June 2025 ANSES proposed classifying CBD as presumed toxic for reproduction. Even with low skin absorption, the advice of a healthcare professional is recommended.
