Specifically formulated for oily, blemish-prone and sensitive skin in adults and teenagers. Effaclar has been through rigorous dermatological testing to ensure it is suitable for use on even the most sensitive skin.Enriched with argilla & kaolin. Argilla gently absorbs sebum from the skin's surface without over-drying or causing micro-inflammation of the sebaceous glands. Kaolin helps to target and remove sebum from deep inside the skin - helping to mattify skin over time.
