It’s Psoriasis Awareness Week and while this condition is not necessarily one which can be treated with beauty products, the research around it unearths some interesting discoveries around skin itself.

For example, a recent study at Rockefeller University showed that stem cells in the skin remember an injury, helping them close recurring wounds faster.

This discovery could advance treatment in psoriasis and the skin in general, especially issues like sun damage, inflammation and premature ageing.
