Dry skin is a skin type characterised by a lack of natural moisture and oil. It often feels tight, rough, or flaky texture and may feel uncomfortable and appear dull. Dry skin can be caused by various factors, such as genetics, environmental conditions, aging, or improper skincare routines. The skin's limited oil production makes it challenging to retain moisture, leading to dryness and a compromised moisture barrier.
Dehydrated skin is a skin condition that can affect any skin type, including oily or combination skin. Unlike dry skin, which is a skin type, dehydration refers to a lack of water content in the skin. It can appear dull, feel tight, and show signs of increased sensitivity, and is often a temporary condition caused by external factors, such as weather, diet, lifestyle, or the use of drying skincare products.
Key Differences: While dry skin is a skin type determined by genetics and oil production, dehydrated skin is a condition resulting from external factors that lead to water loss in the skin. Dry skin lacks natural oils, which compromises the skin's ability to retain moisture, while dehydrated skin lacks water content. Dry skin tends to have a consistent texture throughout, while dehydrated skin can exhibit oily or dry patches in different areas.
