Protective Fluid SPF 30 for blemish-prone skin
Blemish-prone skin is a reality of life for a huge cross-section of society. It affects up to 95% of adolescents and 40% of adults(1). Many people experience post-inflammatory hyperpigmentation or PIH for short, long after the acute blemishes has vanished. After tackling blemishes, they are still stuck fighting their post-blemish marks, which can persist for several years or even a decade(2). Those post-blemish marks left behind after blemishes heal can be even more aggravating and emotionally distressing than the initial blemish itself.
About 1 in 2 people experience post-blemish marks. Men and women are equally susceptible, and all skin types can get them, although it is more prevalent in darker tones of skin(3). Learn more about acne scarring.

How Eucerin DermoPurifyer Protective Fluid works
The DermoPurifyer Protective Fluid SPF30 contains actives that address blemish-prone skin with post-blemish marks in 3 effective ways:
1. Prevents post-inflammatory hyperpigmentation: SPF 30 UVA/B filters protect from sun-induced darkening of post-blemish marks and prevent their appearance
2. Anti-blemish: Antibacterial Decanediol helps to prevent blemishes and Licochalcone A soothes irritations
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). Decanediol further prevents bacterial growth of C. acnes.
3. Anti-shine: Sebum-regulating technology with Carnitine and mattifying pigments deliver a long-lasting, dry, matte finish
Sebum-regulating technology with L-Carnitine reduces excess sebum production (known as seborrhoea).
The Protective Fluid SPF 30 visibly protects from sun-induced darkening of post-blemish marks and prevents their appearance. It prevents blemishes and controls shine.
Complements efficacy of Triple effect serum by helping to accelerate the post-blemish marks fading time to provides physical & emotional relief that improves the quality of life.
Enhanced efficacy when used together with DermoPurifyer Triple Effect Serum.

FAQ (8)

What is post-inflammatory hyperpigmentation (or PIH for short)?
PIH is a type of hyperpigmentation of the skin that is mainly triggered by the way skin regenerates after inflammation. It can affect the face and body, typically especially UV-exposed areas, and appears as flat spots of hyper-colouration. These range in colour from pink to red, brown or black, depending on skin tone and the depth of hyper-colouration. The root cause is increased melanin production, the pigment that defines the colour of a person’s skin, which is stimulated by inflammatory factors. The blemish triggers melanocytes – the melanin-producing cells – to release excessive melanosomes (pigment granules). The excessive pigment granules darken and discolour the formerly stressed area. Once initial blemishes have subsided, spots of hyper-colouration, so-called post-blemish marks, can remain.
Additionally, sun exposure can aggravate PIH symptoms, darkening the affected patches and prolonging the time it takes for them to fade. Most blemish-related PIH will eventually fade over time, but it can take several years or even a decade until it is fully gone*.

Who is affected by post-blemish marks?
Post-inflammatory hyperpigmentation is common among many blemish prone skin sufferers since a root cause for this is inflammation. Those marks left behind after blemishes heal can be even more aggravating and emotionally distressing than the original blemishes. Men and women are equally susceptible, and all skin types can get post-inflammatory hyperpigmentation, although it is more prevalent in darker tones of skin, with over 65% of the Black Americans experiencing it, followed by 53% of Hispanics, 47% of Asians and 25% of Caucasians*. This means that we need effective and tolerable skincare fighting both blemishes and post-inflammatory hyperpigmentation for consumers all over the world.

How can post-blemish marks be prevented?
PIH is mainly triggered by the way skin regenerates after an inflammation. To prevent it, though there are no guarantees, avoid picking at or pressing your pimples. The best prevention is, however, to target blemish-related PIH at the root, meaning preventing blemishes from appearing and getting inflamed. Use a mild but effective cleanser and use light, non-comedogenic skincare with anti-inflammatory ingredients, like Licochalcone A and keratolytic Salicylic acid, which are used in our Eucerin® DermoPurifyer Triple Effect Serum to prevent pores from clogging.
Additionally, sun exposure can aggravate PIH symptoms, so we recommend sun protection. Limit the time you spend in the sun and keep out of the sun during its most intense hours. Wear protective clothing and sun hats whenever possible and apply a sun protection factor of at least 30, to protect marks from darkening and help prevent new marks from appearing. -
What makes the DermoPurifyer Protective Fluid SPF 30 so effective on blemish-prone skin?
With a high sun protection factor (SPF) of 30 plus UVA, it effectively protects from harmful ultraviolet rays, which contribute to darkening of post-blemish marks and prolonging the time for them to fade. In addition, it contains antibacterial Decanediol, which helps to prevent blemishes, and Licochalcone A to soothe irritation. It also contains Sebum-regulating technology to leave the skin with a long-lasting matte and non-shiny look.

What is the benefit of using both DermoPurifyer products together?
The products have enhanced efficacy when used in combination. This is one of the findings of our product-in-use study, among other user responses. In an eight-week study, three groups of 100 volunteers each tested the products: one group used Eucerin® DermoPurifyer Triple Effect Serum alone, one group used Eucerin® DermoPurifyer Protective Fluid SPF 30 alone, while the third group used a regimen of the two products in combination.
After eight weeks, the scores for the regimen cell were the strongest – after regular usage twice daily, volunteers even agreed that it has the highest efficacy of any solution they’ve ever tried* In fact, 95% of users say the combination finally beats their post-blemish marks*.
*Product in use study with 100 volunteers, eight weeks of regular usage twice daily. -
Is exposure to sunlight after applying the products a problem?
No, there is no issue regarding the products in combination with sun exposure. At the same time, skin areas prone to post-inflammatory hyperpigmentation should limit sun exposure, as sun exposure can aggravate symptoms, darkening the affected patches and prolonging the time it can take for them to fade. This is why we recommend using our Eucerin® DermoPurifyer Protective Fluid SPF 30 in addition to the Triple Effect Serum since it includes broad-spectrum ultraviolet radiation filters that protect from both UVA and UVB rays.
