The main cause for blemishes is an excessive sebum production, known as seborrhea, and mostly an abnormal thickening of the external layers of skin. The professional word is hyperkeratosis, which leads to an inadequate desquamation of dead cells. Both in combination cause a clogging of pores, known as comedones: black- or whiteheads in simple terms. These clogged pores are the perfect environment for bacteria (mostly Cutibacterium acnes). Visible inflammation and redness are also most likely to occur. Whether prominent or smaller, pimples are always perceived as a nuisance.

AHA stands for alpha hydroxy acids. These natural substances are found in fruits, among other things, which is why they are also known as fruit acids. The most important AHAs in skin care include glycolic acid, mandelic acid and lactic acid. They work mainly on the skin surface, supporting cell renewal and dissolving dead skin cells. Glycolic Acid helps with oily, blemished skin, as it exfoliates the skin. BHA (beta hydroxy acid) is Salicylic Acid. The fat-soluble substance penetrates deeper into the skin layers than AHAs do. It penetrates the pores, cleansing the sebaceous gland ducts from the inside and thus freeing them from excess sebum. At the same time, it has an anti-inflammatory effect that reduces redness.
Because AHAs are less effective in exfoliation, but therefore gentler, we use more of them. In addition, they usually also have a moisturizing effect. BHA is very effective in exfoliation, so we don’t need much of it. Also, salicylic acid has antibacterial effect.

Salicylic Acid for instance is one of the longest used medicinally. Used externally, it has a primarily corneal dissolving effect, which explains its use in acne and cornification disorders. Human skin regenerates continuously. Older skin cells die, keratinize and eventually exfoliate. This exfoliation is promoted by externally applied salicylic acid. It has a keratolytic efficacy, what means it forces the horny cells of the outermost skin layer to break up and peel off. It frees the pores from impurities and supports the skin’s own natural renewal process.

The NIVEA DERMA Skin Clear Chemical Exfoliator, our hero product, contains in total eight percent of the acid complex. In this dosage, the active ingredient can be used long-term without hesitation.

Niacinamide is a water-soluble derivate of Vitamin B3. It is considered to be particularly well tolerated in skin care and suitable for reducing oily skin. Combination and oily skin prone to blemishes benefits from the anti-inflammatory and sebum-regulating action of Niacinamide. Another invaluable advantage in skin care is that you can combine it with other ingredients.

The products are particularly effective and mild at the same time. The users will experience clear, renewed skin in just seven days. Different kinds of problems like blackheads, whiteheads and pimples, as well as redness and dryness are a thing of the past.

Absolutely. We have tested all our products in clinical studies to have a dermatologist evaluate the blemish fighting and preventing properties of our products as well as their good skin compatibility. But in the end, it is not the expert who should be satisfied, but our consumer. So, we additionally set up a study1 to ask for their feedback. And we could clearly see that the products help with fighting blemishes. 107 consumers tested our Chemical Exfoliator on a daily basis. 93% confirmed a visibly clearer complexion in just seven days. After four weeks 93% confirm that blemishes are visibly reduced.
