Hi and thanks for your query,
Bio oil is good and Medema certainly contains sulphur and steroids
. This drug can have the effect of causing some bleaching of your skin or causing a change in skin color. This might affect some collagen
fibres in the skin and have negative systemic effects if not used appropriately.
My suggestion is you taking an appointment with a dermatologist
. He is better placed to clinically evaluate you, prescribe appropriate drugs that he can easily monitor.
Thanks and hope this helps,
