Dry skin is characterized by a lack of the appropriate amount of water in the most superficial layer of the skin, the epidermis. Dry skin also contains a lower amount of natural lipids such as ceramides. The skin tends to get dryer with age and environmental factors, such as humidity and temperature, have a profound effect on the dryness of the skin. Cold, dry and heated air affects the skin by evaporating moisture and therefore, dry skin is very common during the winter period in Scandinavian countries. Dry skin has a greater need for help than normal skin does and can become sensitive and perceived as tight and irritated.
Treat dry skin gently and use skincare formulated with humectants (water-binding molecules) that can bind water inside the skin. Examples are glycerine, erythriol, urea, low concentrations of lactic acid or the building stone of Hyaluronic acid i.e. N-acetylglucosamine. Also, look for ceramides since dry skin have less of these natural lipids.
Since dry skin often is sensitive, be careful what you expose your skin to. Limit the number of ingredients that the skin can react to and try to use as minimalistic formulas as possible - free from fragrance, glycols, alcohol, preservatives such as formaldehyde donors and phenoxyethanol.
Use a mild cleansing cream in the evening, skip the cleansing step in the morning and avoid harsh cleansers containing, for example, Sodium Laurate Sulphate (SLS).
Be careful with high concentrated treatments/masks with acids (especially AHA &BHA).
Severely dry skin is called xerosis and is considered a disease that needs clinical evaluation by a dermatologist. Clinically dry skin can also be linked to eczema and atopic dermatitis. If you suffer from severely dry skin, we recommend that you book an appointment with a dermatologist and it is not recommended to experiment on your own with cosmetic solutions.
