Dryness & Dehydration
Tightness and dryness are the telltale signs of dry and dehydrated skin. But, these two conditions with similar symptoms have very different triggers at a cellular level.
What’s the difference between dry skin, and dehydrated skin?
Dry skin, or alipoid skin, generally refers to skin that is lacking in oil. Dehydrated skin is characterized by lack of moisture (water) in the Stratum Corneum. This explains why even oily skin can experience dehydration. As mentioned, dehydration is a lack of water, not oil. This means sebaceous oil activity can still be normal or even overactive in dehydrated skin. Both dry and dehydrated skin can experience:
- Irritation, inflammation and itchiness.
- A feeling of tightness or tautness.
- A look or feel of roughness.
- Slight to severe flaking and scaling.
- Fine lines, cracks that can sometimes bleed and severe redness.
One of the biggest consequences is an increase in sensitivity, as dryness and dehydration are precursors to sensitized skin.
