Is Tinted Sunscreen Better Than Regular Sunscreen?
Everyday we are exposed to harmful UV rays - UVA which has a role to play in photo aging, UVB which is responsible for immediate pigment darkening, sunburns, and skin cancer, and visible light like blue light emitted from light bulbs, TV screens, laptops, computers, and mobile phones.
Blue light can cause exacerbation of certain pigmentary disorders such as melasma and post inflammatory hyperpigmentation. For a sunscreen to protect against blue light, it has to be visible on the skin.
Regular sunscreens, however, are formulated as nano-sized (smaller) particles to minimize the white appearance on the skin. Because of the very small particles of regular sunscreens, they are invisible on the skin and thus cannot protect against blue light.
On the other hand, tinted sunscreen contains iron oxides apart from zinc oxide and titanium dioxide that create the visible, skin tone color that can reflect away visible light like blue light.
Using tinted sunscreen, such as SUZANOBAGIMD Tinted Physical Defense SPF50, especially for patients with melasma and post-inflammatory hyperpigmentation has an advantage of protection from both sunlight and blue light as well as instant skin-evening glow.
