BENEFITS OF TINTED SUNSCREENS BEYOND A PRETTY GLOW

Tinted Sunscreens are currently popular. These formulations of mineral-based sunscreen have a colour foundation added that can help balance out skin tone while shielding your skin. Additionally, they may benefit some skin problems because of their capacity to block visible light. Could you finally say goodbye to unattractive sunscreen stains?

How does visible light influence your skin? What is it?

The electromagnetic spectrum includes both visible light and ultraviolet (UV) radiation. UVA, UVB, and UVC are the 3 different wavelengths that make up UV light. The main wavelengths that penetrate the skin’s surface are UVA and UVB because UVC is largely absorbed by the ozone layer. UV rays’ negative effects on skin have a long history of being studied. While UVB has been linked to sunburns and skin cancer, UVA is mostly to blame for premature skin ageing. Sunlight is the main source of UV radiation.

The sun also produces visible light. It is the region of the electromagnetic spectrum that the human eye is capable of seeing. Additionally, artificial sources such as screens, lightbulbs, and medical equipment may produce visible light. At certain wavelengths, visible light has various skin-related therapeutic purposes, such as healing superficial blood vessels, getting rid of undesirable hair, treating acne, and treating precancerous skin problems.

Visible light can harm your skin just as much as UV light, but it penetrates far deeper into the skin. For instance, melasma and post-inflammatory hyperpigmentation have both been linked to visible light’s potential to exacerbate these illnesses of excessive skin pigmentation (dark spots). According to one study, visible light—especially in persons with dark skin tones—caused more obvious, long-lasting hyperpigmentation than UVA alone. This may be especially true for blue light, which appears to stimulate pigment formation more than other visible light spectrum wavelengths (the kind released by gadget screens).

Certain skin issues may be helped by tinted sunscreens

Tinted sunscreens serve to protect your skin from both natural and artificial light while giving you an instant, skin-evening glow.

An increasing number of studies show that those who are prone to hyperpigmentation or melasma may benefit most from using tinted sunscreens. This is because they can filter visible light, which is known to make certain diseases worse. Broad-spectrum sunscreens without a tint have been found to be less effective than tinted sunscreens at preventing melasma relapses. Additionally, it has been demonstrated that tinted sunscreens can lessen hyperpigmentation both on the skin’s surface and under a microscope. Blue light seems to be blocked very well by iron oxide in particular.

Elements in tinted sunscreen

UVA and UVB filters are present in broad-spectrum, untinted sunscreens, however visible light filters are not present in these products. It must be possible to see the sunscreen on skin for it to filter visible light. What’s wrong? Broad-spectrum, untinted sunscreens have their particles “nanosized” (made smaller) to help lessen the white appearance of sunscreen. As a result, since non-tinted sunscreens are designed to be invisible on skin, they cannot prevent visible light.

In tinted sunscreens, pigmentary titanium dioxides and iron oxides are used in addition to broad-spectrum mineral UV filters like zinc oxide and titanium dioxide to produce the skin-tone hue that can reflect away visible light. In order to produce a tinted sunscreen that can be matched to any skin tone, pigmentary titanium dioxide is combined with various ratios of black, red, and yellow iron oxides.

Despite the fact that these pigments are regarded as inactive, iron oxides found in mascara products have been linked to two reports of allergic responses. Other than that, these substances seem to be well tolerated.

What qualities should a tinted sunscreen have?

Selecting a broad-spectrum, tinted sunscreen may help prevent ageing skin damage (due to UVA and UVB filters), avoid skin alterations that can cause cancer, and prevent excessive pigmentation (thanks to the colour base that blocks visible light).

Nowadays, it’s easy to buy tinted sunscreens in retail stores or online. Choose a tinted sunscreen that contains iron oxide if you are prone to hyperpigmentation or melasma (you may find it on the ingredient list).
