What are the hydrating skincare ingredients that will actually help moisturise dry, dull skin?
First, you need to know that there is a difference between MOISTURISING and HYDRATING ingredients. Hydrating ingredients literally add hydration—water—into the skin. Moisturizing ingredients, on the other hand, help keep that hydration in the skin by preventing trans-epidermal water loss (TEWL), the process by which water evaporates from your skin.
You can sk me: what do I need? To MOISTURIZE or HYDRATE my skin? Or may be both?
The right combination of hydrating and moisturizing ingredients will depend on your skin type. Skin that tends to be dry will likely need both hydrating and moisturizing ingredients, whereas with oily skin, more occlusive moisturizing ingredients may cause breakouts.
To help you figure out what to look for, check out some of the most common moisturizing and hydrating skin-care ingredients, recommended by dermatologists:
Glycerin is a humectant, meaning that it draws water to itself. Putting it on your skin helps draw water to the skin.
This ingredient can hold up to 1,000 times its own weight in water. Because it’s present in your body naturally, it’s very unlikely to cause any sort of irritation, so those with sensitive skin should feel comfortable using it within a hand or face cream.
Ceramides are an important part of the stratum corneum, the skin’s natural protective barrier. They exist between your skin cells, helping to seal the barrier shut, which both keeps hydration in and keeps potential irritants out.
I guess these three are the most well-known products.
