The Importance of Hydration

Internal Hydration: The Foundation of Skin Health

Drinking water supports overall bodily functions, including digestion, circulation, and nutrient absorption, all of which indirectly benefit the skin. However, the direct impact of water intake on skin hydration is nuanced. Forefront Dermatology. MDPI

A study published in the National Institutes of Health found that increasing daily water intake improved skin hydration in individuals who previously consumed low amounts of water. Participants who added 2 liters of water daily experienced enhanced skin hydration levels. PMC

Conversely, dermatologists like Dr. Nour Kibbi and Dr. Carolyn Jacobs note that for well-hydrated individuals, additional water consumption may not significantly affect skin moisture levels. They emphasize that the skin's ability to retain moisture largely depends on its lipid barrier, which isn't directly influenced by water intake. Health

Topical Hydration: Strengthening the Skin Barrier

Topical hydration is crucial for maintaining the skin's moisture barrier. Products containing humectants like hyaluronic acid and glycerin attract water to the skin, while occlusives like ceramides and petrolatum lock in moisture. This combination helps prevent transepidermal water loss (TEWL), keeping the skin supple and resilient. Health Wikipedia

Dermatologist Dr. Kate Shuster highlights that well-hydrated skin is more elastic and less prone to dryness and irritation .galendermatology.com
