Skin penetration of CoQ10 in the rat.

: Skin penetration of coenzyme Q10 (CoQ10) was investigated after topical treatment in the rat. The drug was suspended in olive oil and administered at two different concentrations. Coenzyme levels were found to be directly related to the concentrations employed and the contact time. CoQ10 topical treatment might therefore be proposed as a good pharmacological tool in dermatology and cosmetology.
