The client has oily, sensitive skin and cystic acne caused in part by free radical damage. Free radicals' highly reactive molecules contribute to the development and exacerbation of cystic acne on the face. They are often formed due to various factors like inflammation, UV exposure, chemicals in skincare products and pollution. In the context of cystic acne, free radicals can impact the skin in the following ways:

1. Skincare products with harsh or irritating chemicals can disrupt the skin's natural barrier, triggering inflammation. This inflammation generates free radicals, which lead to oxidative stress and damage skin cells and lipids.
   
   The resulting imbalance in sebum production and the inflammation can clog pores, creating an environment conducive to cystic acne formation.
   
   
2. Oxidative stress: Free radicals can cause oxidative stress in the skin, which damages skin cells and lipids. This oxidative stress can disrupt the normal processes of sebum production, making the skin more prone to clogged pores, a precursor to cystic acne.
   
   
3. Impaired healing: Free radicals can interfere with the skin's ability to heal and repair itself, making it harder for the body to resolve existing cystic acne lesions and prevent new ones from forming.
