People usually worry about UVA and UVB rays, but what about the visible light? Visible light is transmitted by fluorescent lamps, such as those that illuminate indoor environments, artificial lighting, computer light and the clarity that enters through the window.
How Does Visible Light Affect Skin?
Computer light and fluorescent lamps can cause pigmentation and melasma (dark spots) and also accelerate the aging of the skin. Visible light is able to produce free radicals, which cause changes in cells, especially melanocytes (pigmentation cells) and fibroblasts (collagen producers).
Although exposure to visible indoor light is far less harmful than exposure to sunlight, experts say that everyone should protect themselves, especially people who are under skin treatments (such as peeling and laser) or have diseases triggered by the sun (such as lupus).
Of course, if you stay one day or another without protection, it will not cause any damage to your skin. The problem is this exposure without long-term protection.
What to use to protect yourself from visible light?
The only type of product that blocks the effect of visible light on the skin is the physical filters, which reflect and disperse light energy, building a physical barrier to solar radiation.
It can be a facial base or that thicker filter (which leaves white), which has zinc particles and acts as a protective film that prevents radiation from overlying the skin.
In addition to the facial base can also be used face powder or powder base. Ideally, makeup has a protective factor between 10 and 20 – it does not need more than that. But if you are exposed to sunlight, use a sunscreen before applying the base.
Besides the facial base, other ways to protect yourself from computer light are the protectors of color, bb cream, and cc cream. These products also form a protective layer on the skin, avoiding the damage caused by light. They are great for use during the day because they already have sun protection.
