The Eucerin DermoPurifyer Triple Effect Serum contains actives that address acne-prone skin with post-acne marks in 3 effective ways:
1. Anti-marks: Patented Thiamidol visibly reduces persistent post-acne marks and prevents their appearance

Thiamidol acts at the root cause of hyperpigmentation by inhibiting melanin production in skin so existing dark spots fade and fewer new dark spots form. It now has been included in the new Triple Effect Serum tailored for acne-prone skin. It was clinically proven to effectively reduce post-acne marks and prevent their formation. The first results are visible after just two weeks and improve continuously with regular use.
2. Anti-blemish: Signature DermoPurifyer ingredients Licochalcone A and Salicylic Acid effectively reduce blemishes and prevent new ones from appearing

Licochalcone A is a powerful anti-inflammatory that works against micro-inflammation, soothes irritation and helps to reduce redness. Additionally, it has been shown that it inhibits C. acnes Biofilm-associated lipase activity (in vitro). Salicylic Acid has a comedolytic effect and addresses hyperkeratosis: It removes dead skin cells and softens skin to help prevent blocked pores. It also has antibacterial properties.
3. Anti-shine: Sebum-regulating technology with mattifying pigments give a long-lasting, dry, matt finish

The Triple Effect Serum visibly reduces and prevents 1) persistent post-acne marks and 2) blemishes, and 3) controls shine. By helping to accelerate the post-acne marks fading time, Triple Effect Serum provides physical & emotional relief that improves the quality of life.
Enhanced efficacy when used in combination with the
DermoPurifyer Protective Fluid SPF 30.

Hi Mash.
Thank you for your enquiry. The recommendation on the use of this product is the following: Pat the serum or gently rub onto the skin. Excessive spreading may lead to pilling. Frequent rubbing motion will rub off the formulation from the skin. It is also vitally important to allow the formula to sink into the skin. It is recommended that you wait at least 60 second before the next skin routine step. The formula has very effective ingredients and it is not therefore necessary, to use a large amount of it when doing the application. The correct amount is 1 pump only. This would be the case for the Protective Fluid as well. We hope that this will assist and thank you again for taking the trouble to get in touch.

Hi Tee.
Thank you for your enquiry. We would recommend that you wait about 10 minutes after applying the Triple Effect Serum, after which you should be able to apply the Protective Fluid SPF 30.
