On information gathered by the COF of Almería, the BBC interviewed Justine Kluk, a member of the British Association of Dermatologists. The expert highlights the six essential components in a moisturizer . “Know your role and keep them in mind will help customers successfully choose the next product you will buy , ” says Kluk.
The Sun Protection facto is the number indicating the time can be exposed skin (protected) without burning due to sunlight . Kluk explains that “every morning using a moisturizer with an SPF of 30 or higher retards the signs of skin aging and reduces the chances of developing skin cancer.” There are also cosmetics including FPS, but warns dermatologist to be sure that this is a product with broad spectrum protection to protect the skin from UVA and UVB rays.
UVB rays are the cause of skin burns, while UVA are associated with long – term skin damage and directly with skin cancer. Sunlight is the main source of ultraviolet radiation and major risk factor for most skin cancers.
“Their main benefit is that neutralize the damage that make your skin free radicals , ” says Kluk. Free radicals are molecules with unpaired electrons and therefore unstable. They form in many body processes, by metabolism or by the immune system when attacking viruses and bacteria, but also by environmental factors such as pollution or ultraviolet rays.
Kluk clear that “the antioxidants should be applied immediately after cleaning the skin for absorption best”. The expert also recommends sera with vitamin C.
Retinol belongs to the family of retinoids, derivatives of vitamin A. “erases dark spots and fine lines , evens skin tone and closes pores” says dermatologist. Although experts agree that this ingredient needs to adapt to the skin of each person , so it is advisable to start your application before the summer months once or twice a week and at night. Eventually you may increase the dose to make safe use daily.
It is not recommended to start treatment of retinol during the summer because this component may make the skin more sensitive to the sun . Kluk says that ” it is better to apply creams with retinol overnight and then in the morning using a moisturizer with sunscreen.” For that retinol is effective and skin changes are visible, they must spend at least 12 weeks “in which flaking and redness are part of the process”, according to experts.
AHAs are alpha hydroxy acids, which sometimes contained in cosmetics labels as glycolic acid or salicylic acid . “I prefer to include them in products to clean the face , ” says Kluk. Environmental factors and stress, besides the sun, causing a gradual slowdown in the rate of cell turnover and skin aging. The aha ” prevent dead skin cells accumulate so that basically function as an exfoliant . Also prevent the pores are blocked and bring light to the face , “says Kluk.
Collagen is a protein molecule secreted by connective tissue cells. It is the most abundant component in the skin and bones, “but after serving 26 years begin to decline collagen levels , ” said the specialist. Decreases up to 1 percent each year, affecting the smoothness of the skin.
Including peptides in cosmetics “are basically protein fragments that are used to increase the level of collagen and to return the firmer and smoother skin , ” says Kluk. This type of compounds are mainly in the specific eye creams . On labels, “should look like matrixyl”.
Hyaluronic acid is a humectant compound “which means that retains water molecules lapiel ” according to the expert. Kluk recommended to apply as a night cream, because it is the perfect choice to moisturize the skin before going to bed. Creams based on hyaluronic acid are available in all formats and at different prices.
