Impure skin is caused by excess production of sebum and excessive cell production. Products with ingredients that regulate sebum production, as well as regular peeling in line with given skin conditions, can help reduce impurities.

Enlarged pores are usually found in oily skin – but also in impure skin. The condition is caused by excessive sebum production. If the pore (i.e. the sebaceous gland follicle channel) is blocked, it will enlarge and horny cells will collect at the entrance. Pore cleansing and pore-refining ingredients, as well as ingredients that regulate sebum production, are recommended for treating enlarged pores.

Reddening / couperose have a variety of causes. Couperose can form from reddened skin. Couperose skin is characterized by burst capillaries, usually in the nose and cheek areas. Ingredients that reduce reddening and special products for couperose can help here. It is also recommended that external measures be taken to support skin thickness and skin resistance.

Pigment modifications / pigment spots usually form as a result of excessive exposure of the skin to UV radiation. Here, skin appears spotty, uneven, and old. Sometimes, however, pigment modifications can be caused by hormones, in which case unattractive spots usually appear on the forehead and cheeks. Scars and acne scars can also cause pigment disorders. It is recommended here that ingredients that lighten the skin be applied. Additionally, a product offering a high degree of sun protection can be used on a daily basis as a preventive measure.

Keratosis (so-called "chicken skin") mainly affects people whose skin is prone to dryness. Keratosis can be congenital or it can be acquired either through permanently dry skin or excessive exposure to UV radiation (actinic keratosis). It usually occurs on the extensor side of the upper arms and thighs as an irregularity of the horny layer with numerous rough papules. Anti-inflammatory ingredients and those that counteract horny layer irregularities help improve the skin's rough appearance here.

UV stress manifests itself in many different ways – e.g. in the form of pigment disorders, lines and wrinkles, a loss of elasticity, reddening, enlarged pores, etc. It is important here to optimally protect the skin against further damage by consistently utilizing products with a high sun protection factor, effectively addressing specific skin conditions, peeling the skin in order to make it easier for young skin cells to rise to the surface, stimulating new collagen production, and strengthening the skin barrier.

Ageing skin is also viewed by us as a skin condition, whereby each type of skin ages differently. For example, normal and dry skin develop lines and wrinkles that are more pronounced than those of oily and combination skin, and the ageing process also begins earlier with the former types of skin. Ageing skin is marked by, among other things, a loss of elasticity, increasing lines, ever-deeper wrinkles, and an uneven complexion. The natural ageing process is often accelerated by excessive UV radiation exposure. Sunlight has many different negative effects on skin. These effects manifest themselves in the form of pigment disorders, dry skin, lines and wrinkles, a loss of elasticity, reddening, and enlarged pores. It is important to provide the skin with daily protection against UV radiation and to use products with ingredients that stimulate collagen synthesis. One of the main goals here is to achieve skin cell regeneration by means of peelings in line with given skin conditions.
