Definition: A spray, cream, gel or powder that provides protection against the sun’s harmful ultra-violet A (UVA) radiation, which causes cellular-level damage, and ultra-violet B (UVB) radiation, which causes surface-layer sunburns and pigment changes. Chemical sunscreens absorb the sun’s rays while mineral-based blockers reflect the rays away from the skin. To measure the amount of protection from UVB rays a sunscreen can offer, formulas are labeled with a sun protection factor (SPF) number, which determines the length of time someone can stay in the sun without sunscreen before receiving a sunburn. However, in 2012, the FDA mandated that all sunscreens go through reformulation to receive a broad-spectrum label that declares its ability to protect against UVA and UVB rays.
Benefits: All experts would agree with Hernandez, who says, “The sun is the number-one aging element in the world.” Once sun damage occurs at the cellular level, it’s incredibly hard to reverse, so prevention is key. And since sun damage from earlier years doesn’t present until late 30s and 40s, it’s always the right time to protect against future damage.
Frequency: To be applied each morning only. (Violet Says: Sunblock only lasts two to three hours, after which your skin becomes more prone to UVA and UVB sun damage. Reapply accordingly.)
Order of application: If your daily moisturizer does not include an SPF of 30 or higher, add on an extra layer of sunscreen following your face cream.
