The Science Behind Silymarin CF
Targeted Antioxidant Protection
While all vitamin C serums offer protection from free radicals, Silymarin CF is specifically designed to combat oil oxidation—a newly recognised contributor to blemish formation. When excess oil oxidises, it creates damaging free radicals that can irritate pores and accelerate signs of ageing. This formula addresses that process at the source.
Regulate Oil and Prevent Breakouts
Silymarin, an antioxidant extracted from milk thistle, helps reduce the oxidative stress caused by sebum buildup. Paired with salicylic acid, this serum helps to regulate oil production, improve skin clarity, and reduce the likelihood of blemishes and visible pores—without drying or stripping the skin.
Ideal Pairing With Aesthetic Treatments
Silymarin CF complements a wide range of professional retexturing treatments such as chemical peels, microneedling, and light therapies. These procedures help reduce sebum production and increase skin turnover—while Silymarin CF enhances results by protecting the skin from oxidative damage and boosting post-treatment clarity.
