Eucerin Dermo Purifyer Post Blemish Protective Fluid SPF 30 enables you to prevent blemishes and finally beat post-acne marks with 3 key factors. UVA/B filters protect from sun-induced darkening of post-acne marks and prevent their appearance. Antibacterial Decanediol helps to prevent blemishes and Licochalcone A soothes irritations. Anti-shine Sebum Regulating Technology delivers a long-lasting, dry, matt finish. Licochalcone A is a powerful antioxidant, anti-inflammatory and skin-soothing ingredient. When used in skincare products, Licochalcone A works to reduce inflammation and neutralize free radicals that negatively influence skin cells and accelerate the aging process. It helps to protect the deeper epidermal skin layers from sun-induced effects. Decandiol (Decylene Glycol) is a moisturising ingredient with anti-bacterial properties. It is known to fight bacteria such as Cutibacterium acnes (which is involved in the development of acne) and Staphylococcus aureus (which plays an important role in Atopic Dermatitis). Long after the acute acne has faded, up to 50% of people experience post-acne markings (also known as post-inflammatory hyperpigmentation or PIH), which can last up to 5 years. Acne accompanied by PIH is often more emotionally and physically burdensome than acne alone. Now, thanks to Eucerin, victory is visible. Eucerin DermoPurifyer Protective Fluid SPF 30 is the solution for acne-prone skin with post-acne marks. Formulated with SPF to protect marks from darkening due to sun exposure.
