What is it and what is it used for?SkinCeuticals Oil Shield is a sunscreen that can also minimize the appearance of oiliness on the skin, for a drier appearance. This product is made with two active ingredients: silica gel and a broad-spectrum sunscreen. First of all, the sun is largely responsible for skin conditions such as sunburn, premature aging and other more serious problems. It emits two types of radiation: UVA and UVB. UVA radiation is the most common, accounting for 95%, but it is also responsible for directly damaging the most exposed cells. Therefore, it contributes to the appearance of wrinkles over time. UVB radiation, on the other hand, causes sunburn. Both types can lead to the appearance of age spots. Therefore, the SPF 50 protection of this cream can greatly help mitigate these effects. These radiations are measured on a frequency spectrum, so the higher the SPF value, the more protected the skin will be. Secondly, silica concentrates directly in the pores and oils of the skin. These are two very important and decisive factors in the health and appearance of the skin. This is due to the following reasons: The pores in our skin allow it to breathe and perform its normal functions. These pores tend to become blocked due to thick skin secretions or environmental pollutants. Regardless of the cause, this can lead to irritation, inflammation, and even acne. Excess sebum is responsible for the oily appearance of the skin. This skin type is very prone to acne at any time. Therefore, silica has the ability to absorb sebum and largely close pores to control its production. Who is it for? It is suitable for people with normal, normal to oily, oily or combination skin.
