Harnessing the Power of UV Filters in Sunscreens: Defense Against Sun Damage

Exposure to the environment plays an integral role in skin aging. It is estimated that 80% of the signs of aging seen on the skin is a result of long-term sun exposure.

UV filters will reflect or absorb UVA and/or UVB radiation from the sun.

This protects the skin from sunburn, but also from destruction of the skin barrier, inflammation, collagen degradation, and uneven skin tone (hyperpigmentation).

UV filters are essential ingredients in every skincare regime.


Understanding UV Filters in Sunscreen: Protection from Harmful Radiation

UV filters reflect or absorb UV radiation to provide protection from the sun.

The Science Behind Effective Sun Protection: Which UV Filter Works Best?

Sunlight contains both UVA and UVB radiation. UVA radiation (320-360nm) penetrates the skin deeper than UVB radiation (290-320nm) and causes premature aging (via collagen destruction).

However, UVB radiation is responsible for sunburn. Altogether, exposure to UV radiation causes damage to DNA, impairment of the skin barrier, dehydration, suppression of the immune system, and skin aging.

Exploring UV Filter Sunscreen for Comprehensive Sun Protection

It is estimated that 80% of the signs of aging seen on the skin, come from long-term exposure to UV radiation.¹ In addition, some cosmeceutical active ingredients can make the skin more sensitive to the sun.

Therefore, it is essential that all skincare regimes contain broad-spectrum daily sunscreen with UV filters.

Chemical UV Filters in Sunscreens: Unraveling Their Role in Sun Protection Formulation

UV filters can be categorised as organic (chemical) or inorganic (mineral). Organic filters will absorb UV radiation, while inorganic filters will reflect or scatter UV radiation.

UV filters can protect against UVA radiation, UVB radiation, or both.² In skincare formulation, is it essential to combine UV filters to provide protection against UVA and UVB radiation (broad spectrum sunscreens) as this will protect from burning and aging.


What are UV filter sunscreens, and how do they differ from other types of sunscreens?

UV filter sunscreens contain active ingredients that either absorb or reflect UV radiation to protect the skin from the sun's harmful rays.

These sunscreens are categorized based on their UV filters, which can be organic (chemical) or inorganic (mineral).

Which sunscreen is most effective at blocking UV light, and what factors should be considered when choosing a sunscreen?

The effectiveness of a sunscreen in blocking UV light depends on its UV filters and formulation.

Broad-spectrum sunscreens containing a combination of UV filters offer the most comprehensive protection against both UVA and UVB radiation.

When choosing a sunscreen, consider factors such as SPF level, skin type, and any specific needs, such as UV filter hair products for additional protection.
