Smoking actually affects acne. It increases an inflammatory cytokine called interleukin 1a and this is a trigger of blackheads and acne. There is a very strong correlation in female adult acne and smoking.
Nicotine has been shown to have a hyperkeratizing effect. This means it makes your skin massively overproduce skin cells. These cells end up clogging the top of the follicle leading to breakouts.
With acne skins who smoke they have a predominance of micro and macro comedones with only a few inflammatory lesions.
The best products to help address this is Roccoco Botanicals Clarifying C Serum and Roccoco Botanicals Mandelic + Fusion. Both are available in clinic.
Even with the best products in the world lifestyle factors limit results of products.
