No Cosmetics Retinol Serum

Hello Abt1, thank you for your question. Retinol Serum is formulated with 2% retinoids and 0.01% retinol in order to be best tolerated by the skin and as effective as possible. For further information, however, we recommend that you do not use our retinol serum during pregnancy or while breast-feeding. And remember to protect yourself from the sun when using retinol. Sincerely, your M-Infoline team
