It is common to have the misconception that dry and dehydrated skin essentially means the same thing. But in actual fact, there is a difference between dry and dehydrated skin.
When your skin is dry, it means that your skin is not producing sufficient sebum. Dry skin tends to have small pores due to the lack of oil being produced in the skin. When your skin is dry, it is unable to retain moisture. This is because the skin requires oil to hold on to moisture which often make it look rough and flaky, resulting in the appearance of wrinkles and fine lines. Dry skin also tends to be more inflamed and easily irritated, this could lead to a series of chain reaction where your skin ends up having a lack of collagen and elastin breakdown.
On the other hand, dehydration means that your skin lacks water content, but may still produce oil. You do not need to have dry skin to have dehydrated skin. In fact, people with oily and combination skin can have dehydrated skin as well. It may be genetic or caused by external factors. Dehydrated skin generally feels tight and can form fine lines easily due to the surface cells lacking water that normally makes the surface smoother. If looked closely through a magnifying glass, dehydrated skin has tiny triangular fine lines. Dehydrated skin is common among those with oily and acne-prone skin who use harsh products that strip the skin of water.
So, get rid of the misconception and remember to take note of these little differences in order to find the best matching skin care products for your skin!
