Does oily skin need a moisturizer?
Oily skin is prone to excess sebum production, so the main aim of treating this type of skin is to reduce shininess and stickiness on the surface of the skin. Because of this, some people with oily skin prefer not to use moisturizer as they feel it could make their skin even oilier.
Is it true?
Skin hydration depends on how much water the epidermis can keep in. Even if the skin feels oily and sticky due to unwanted oil production, it can become dehydrated if the epidermis doesn’t retain enough water.
Moisturizers play a role not just to increase the skin oil, but to seal moisturizing agents into the skin in order to stop the skin water loss. In this way they help to prevent skin dryness and offer protection for the skin. For oily skin, a moisturizer will hydrate the skin’s surface and help control sebum production, forming an effective barrier and stop over-production of oil.
Moisturizers for oily skin should be chosen to hydrate the skin as well as to control the sebum production. Jojoba oil or squalane oil can be suitable for this type of skin even though they are oil based, as they partly have the same composition of sebum. In this way they are absorbed well into the skin and can help to inhibit the production of natural oils. Other than that, light textured moisturizers such as hydration milk lotion or hydrating gel that are not rich in oil base would be recommended for oily skin types.
