Why Does Skin Need Moisturizing?
The outer layer of skin needs to maintain an ideal water content of about 20-30% to stay soft, smooth, and healthy. Dry environments, over-cleansing, or a damaged skin barrier can lead to moisture loss, which causes tightness, flaking, and increased sensitivity. Hence, effective moisturizing prepares for other skincare steps.
3 Core Moisturizing Ingredients
Humectants (e.g., hyaluronic acid, glycerin): Act like sponges to “draw” moisture from the air and deeper skin layers, providing instant hydration to the surface.
Occlusives (e.g., squalane, mineral oil): Form a protective film on the skin’s surface to prevent water evaporation and lock in moisture physically.
Emollients (e.g., ceramides, fatty acids): Fill gaps between skin cells, smooth texture, and help strengthen the skin’s natural barrier.
Where Are Moisturizing Ingredients Used?
In basic skincare products: face creams, serums, body lotions, etc.
In basic cosmetics: makeup, primers,and foundations.
Of course, they can also be used in shampoos and conditioners, as well as aftershave care and oral moisturizing products.
