Winter skin, summer skin: what really changes

Skin is not immutable. It constantly reacts to its environment. In Canada, where the contrasts between summer and winter are marked, these variations are particularly noticeable.

In winter, cold outdoor air and indoor heating significantly reduce ambient humidity. Under these conditions, the skin loses its natural moisture more easily. This phenomenon is well-documented: the skin barrier becomes more vulnerable, and transepidermal water loss increases. The skin doesn't lack water in the strict sense; it simply retains it less effectively.

Conversely, during the summer, the humidity in the air and the increased activity of the sebaceous glands help to maintain a certain balance. The skin recovers more quickly, even when exposed to the sun or heat.

This is why the skin's needs vary with the seasons. In winter, it's not about doing more, but doing things differently. Adapt your routine, prioritize comfort, support the skin barrier, and avoid excesses. Simple adjustments, guided by the context rather than by a desire for correction.

What changes / What remains

What changes in winter

• The humidity in the air decreases sharply

• The skin barrier retains water less effectively.

• The skin becomes more reactive to temperature variations

• Skin comfort requires more attention

What remains

• The skin continues to regulate itself naturally

• Basic needs do not change

• Simple actions remain the most effective

• Consistency matters more than intensity

Adapting your care in winter does not mean “doing more”, but working with the context .

Observing these changes allows you to develop a more balanced relationship with your skin. A relationship that takes into account the environment, the climate, and the rhythm of the seasons. Without dramatizing, without overinterpreting, simply by listening to what is there.

At Selv, skincare is based on this logic of adaptation. Not to transform the skin, but to support it, season after season, with consistency and respect.
