DermoPurifyer Triple Effect Serum
Product info
Triple Effect Serum for blemish-prone skin with post-acne marks.
Acne is a fact of life for a huge cross-section of society. It affects up to 95% of adolescents and 40% of adults1. Many people experience post-acne marks (Post-inflammatory hyperpigmentation or PIH for short) long after the acute acne has vanished. After tackling blemishes, they are still stuck fighting their post-acne marks, which can persist for several years or even a decade2 with the sun aggravating the symptoms.
About 1 in 2 people experience post-acne marks. Men and women are equally susceptible, and all skin types can get post-acne marks, although it is more prevalent in darker tones of skin3.
Eucerin DermoPure Triple Effect Serum with patented Thiamidol enables you to finally beat blemishes and post-acne marks with 3 key factors:
1 Anti-marks: Patented Thiamidol acts at the root cause of hyperpigmentation to reduce persistent post-acne marks and prevent their appearance.
2 Anti-blemish: Salicylic Acid effectively reduces blemishes and Licochalcone A helps to prevent new blemishes from appearing.
3 Anti-shine: Sebum Regulating Technology delivers a long-lasting dry, matt finish.
The Triple Effect Serum has enhanced efficacy when used together with the Eucerin DermoPure Protective Fluid SPF 30. In fact, respondents in our studies report that the products not only improved their lives and provided relief, but also have the highest efficacy against post-acne marks of any products they have ever tried. “The combination beats post-acne marks,” say 95% of users4.
