What determines my skin type?

The term skin type describes the condition of the skin and is also referred to as skin condition in dermacomsmetics. The skin condition can change over time and depends on many internal and external factors. Everyone inherits a basic skin condition through their genes, but this condition can develop differently from that of their parents due to various factors.

With age, the skin usually becomes drier, impurities subside and pigmentation spots form. Exposure to sunlight, extreme climatic conditions, dry air, hormonal influences, diseases, medication and many other factors affect the skin and its behavior. Therefore, cosmetic skin care must always be adapted to the current skin needs.

Picture with the word: Oily skin

What is oily skin?

Oily skin is characterized by increased sebum and sweat production and produces an oily film, especially on the chin, forehead and nose. The skin tends to have large pores and blackheads, which can also develop into acne if predisposed to it. Oily skin usually goes hand in hand with oily hair. The oily skin condition usually appears from puberty onwards and normalizes in the course of life, whereby the oily condition is only limited to the T-zone (combination skin). This skin condition is very rare after the age of 50. The positive aspect of this skin condition is the strong robustness and resistance against acids, alkaline solutions and solar radiation. Despite its robustness, oily skin also needs the right care in order to adapt to the normal skin condition.

How to care for oily skin?


Aim: Slowing down the excessive production of sebum, allowing the sebum to drain away evenly, binding the excess fat on the skin and preventing blackheads by avoiding comedogenic substances.

Cleansing: Betaines, ether sulphates and similar ionic surfactants are suitable for cleansing the face. They have a drying effect and an antibacterial effect due to a slightly acidic pH value of 5.5. Shower or bath oils with refattening agents are rather unsuitable. A peeling can be carried out several times a week to open blackheads and absorb skin fat. However, the skin should not be irritated. Fat-absorbing masks are also effective.

Toning: A mixture with a 30% alcohol content and antibacterial, anti-inflammatory and astringent (astringent) active ingredients is suitable as a facial toner. After cleansing, the toner is evenly distributed over the face with a cloth or cotton pad.

Care: As skin care, a hydrogel or O/W cream with a high emulsifier content and little fat is suitable for absorbing the excess sebum. Antiseptics, anti-inflammatory substances like allantoin and keratolytic substances like salicylic acid which refine the skin texture are suitable active agents. For the night care the day care product cane be used, a special night care is not necessary. During the cold months it is recommended to use additional moisture concentrates to counteract the dehydration caused by the dry room air.
