How Sleep Deprivation May Affect Skin Barrier and Elasticity
Original title: 잠 못 자면 피부가 왜 이상해질까
When sleep is insufficient, cortisol levels may rise — and this can affect skin barrier function and elasticity over time, making a supportive nighttime skincare routine an important part of overall skin condition care.

Main Summary
After a night of poor sleep, you may notice that your skin feels dull, tight, or puffy the next morning. This is not simply a result of fatigue — it may be connected to what happens to the skin during sleep.
When sleep is insufficient, cortisol — the body's stress hormone — may increase. Elevated cortisol can affect the components that make up the skin barrier, which may in turn impact the skin's ability to retain moisture and maintain elasticity. The skin's natural nighttime activity may also be less effective when rest is inadequate.
Based on this relationship between sleep and skin condition, DR.COHEN emphasizes the importance of a supportive evening routine — one that helps keep the skin barrier comfortable and well-hydrated. EG ACTIVE+ Protein Cream, formulated with EGF-related ingredients and a protein complex, can be incorporated into a nighttime routine as part of skin condition care.
DR.COHEN's Perspective
DR.COHEN views skin condition management in two phases: defending against daytime stressors, and supporting the skin during nighttime rest.
Sleep is a time when the skin is away from external triggers and can settle into a comfortable state. DR.COHEN therefore emphasizes that supporting skin barrier care and hydration as part of the evening routine is important. EG ACTIVE+ Protein Cream can be used as the finishing step of a nighttime skincare routine.
DR.COHEN's nighttime routine philosophy follows this flow: skin barrier care → hydration support → elasticity care → comfortable overnight skin condition management.

A. An evening routine can be structured as: cleansing → hydrating toner → functional serum → finishing cream. Prioritizing skin barrier care and hydration in the evening is especially helpful.
Q. Is DR.COHEN EG ACTIVE+ Protein Cream suitable for nighttime use?

Expression Cautions
- ⚠Avoid 'skin regenerates during sleep' — use 'the skin may benefit from a comfortable, settled state during rest' instead.
- ⚠Avoid emotionally charged phrases like 'cortisol ruins your skin' — state 'increased cortisol may affect skin barrier function' as a research-informed explanation.
- ⚠Avoid claims like 'just sleeping well fixes your skin' — use 'adequate sleep may support skin condition management' instead.
