Six key ingredients that support winter skin

The following ingredients are often recommended by skin experts for dry sensitive winter skin.

Ectoine is a protective ingredient that helps skin cope with environmental stress such as cold wind and dry air.

It supports the area around skin cells and helps reduce redness tightness and discomfort caused by winter conditions.

Ectoine based moisturizers are helpful before going outside or spending a long time in heated indoor spaces.

2 Trehalose

Trehalose is known as an ingredient found in so called resurrection plants.

It binds water and forms a light protective film on the skin so it is very useful for relieving winter dryness and rough texture.

If your skin feels tight right after cleansing or your cheeks become flaky in winter a cream containing trehalose can help.

3 Phytosphingosine

Phytosphingosine is a precursor of ceramides which are a key part of the skin barrier.

It supports barrier recovery when the skin has become fragile due to cold dry weather and frequent irritation.

This type of cream is suitable when skin feels sore or stings easily and small blemishes appear more often than usual.

4 Lactobionic acid PHA

Lactobionic acid belongs to the PHA group and offers very gentle exfoliation.

It smooths the surface of the skin while keeping moisture in place so it is ideal for winter when harsh acids are too strong.

If makeup does not sit well and skin feels rough a PHA toner can help to refine texture without strong irritation.

5 Glyceryl glucoside

Glyceryl glucoside supports the water channels inside the skin often called aquaporins and helps improve inner dryness.

It is especially helpful when the surface looks fine but the skin feels empty and tight from within.

These creams give a long lasting hydrated feeling and are suitable for people who struggle with inner dryness throughout winter.

6 Carnosine

Carnosine is a support ingredient for firmness and resistance to stress.

It helps the skin cope with dryness and environmental factors that can speed up visible aging and dullness.
