Skin care and cleansing. Basic principle: As little degreasing of the skin as possible! As little irritating cleansing agents as possible, i.e. sparing use of soaps or syndets. No use of liquid soaps, as there is a risk of over-abundant and thus useless use. Instead, use soap bars or syndet-containing washings; soaping the armpits, groin and genitals, the anal region, the feet and, in the case of obese people, the abdominal folds is generally sufficient. Rinse thoroughly so that no irritating "soap residues" are left behind. Mild cleansing of the body skin with hydrophilic body oils (mixable with water). Hereby a sufficient cleansing effect and at the same time moisturising care is achieved. Instead of hydrophilic oils also O/W emulsions may be used (e.g. Abitima Lotion, Excipial U Hydrolotio, Sebamed Lotion). Briefly shower the skin, apply and distribute the emulsion on the moist skin, shower again briefly, the remaining emulsion film will not be perceived as unpleasant.
Baths: Baths are important and recommended for skin care. Different bath additives depending on the skin condition (see Pityriasis rubra pilaris, table 1). Oil or bran baths (see bran extract below) are helpful for eczematized and irritated skin. The patient should be familiarized with the therapy modalities and be able to prepare the baths himself, e.g. oil baths as"Cleopatra bath" or bran baths. In Kneipp books milk whey or camomile oil baths are recommended. Immediately after the bath therapy and other washing procedures, the ointments are applied to the still moist skin. This enables the skin to store moisture for a long time. The fat content of the ointments depends on the individual "skin sensation" of the patients. All variations are possible here. Good effects are achieved with saline, urea or propylene glycol containing ointments R146.
