dryness and dehydration
overviewback to top
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. Learn the difference and find your products for hydrated, healthier skin.
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.

what are the top three causes of dry, dehydrated skin?
Intrinsic aging is the normal process of physical change over time that’s more about genetics than lifestyle. (Lifestyle-induced aging is known as premature aging.) Activity of the sebaceous glands responsible for oil secretions tend to decrease with age, and the skin’s natural hydrators decline over the years. Aging also may cause blood flow to the skin to decrease, causing a drop in sebum production.
Weather / Environmental Elements
Prolonged exposure to the sun causes water to evaporate from skin, which is why sunburnt skin requires more moisturization than unexposed areas. Likewise, cold winds, air conditioning units, forced air heating and low temperatures can also dry out skin, contributing to premature aging.
The trend of fat-free diets can deprive our bodies of skin-friendly Essential Fatty Acids (EFAs). This deficiency can result in chronic itching, dryness, scaling, thinning and can lead to an imbalance in prostaglandins (chemical messengers that do many things, such as control inflammation). Excess intake of alcoholic beverages and certain medications (such as nasal decongestants) can also contribute to dry skin.
