Many people have cottoned on to the fact that acids like glycolic, lactic and salycilic acid can help keep your skin looking young and fresh by creating a glow which can only come from great exfoliation. However, if you’re not following up your exfoliating treatments with an spf then you could be doing more harm than good. These products exfoliate the skin, encouraging skin cell turnover. That means that the cells at the top of the dermis are younger and therefore more vulnerable to sum damage. So, if you don’t use a sunscreen whilst using these products you’re more at risk of developing wrinkles, age spots and even skin cancer. So don’t forget that SPF!
