Summary

Beta Hydroxy Acids, primarily salicylic acid, are oil-soluble chemical exfoliants that penetrate pores to remove dead skin cells and reduce inflammation. From a healthspan perspective, they primarily address 'inflammaging' and photoaging in the skin by improving texture, reducing fine lines, and maintaining the integrity of the skin barrier, the body's first line of defense against pathogens and environmental damage.

Purpose
