PHOTOAGING AND SUN PROTECTION: WHY UVA DEFENSE IS ESSENTIAL TO PREVENT SKIN AGING

Dr. Gabbanini – Quality Control Manager, BeC Natura

When we think about sunscreens, the first thing that comes to mind is the prevention of sunburn. For decades, sun care products have been used to protect the skin from erythema caused by ultraviolet radiation, allowing safer exposure to the sun.

However, scientific and medical evidence has shown that sun protection is important not only to prevent sunburn but also as an essential tool in combating photoaging, the premature aging of the skin caused by chronic exposure to sunlight.

UVB Rays: the main cause of sunburn

UVB rays are highly energetic and are absorbed by the outermost layers of the skin. These rays are responsible for redness and the typical sunburn reaction.

Paradoxically, pain and erythema represent an important defense mechanism of the body, warning us that it is time to stop sun exposure before more serious damage occurs.

UVA rays and photoaging: the invisible enemy of the skin

The true culprits behind skin photoaging are UVA rays.

Although less energetic than UVB rays, UVA radiation penetrates much deeper into the dermis. For this reason, it can cause progressive and often irreversible damage.

Prolonged exposure to UVA rays impairs the function of fibroblasts, the cells responsible for producing collagen and elastin, two essential components that maintain the skin's firmness, elasticity, and youthful appearance.

Over time, this process contributes to:

• Premature wrinkles

• Loss of skin firmness and elasticity

• Skin sagging

• Dark spots and pigmentation irregularities

• Dull and uneven complexion

• Increased risk of photocarcinogenesis

Photoaging is therefore one of the leading causes of visible skin aging and can be prevented through responsible sun exposure and the use of effective sun protection products.

How to choose an effective sunscreen

When selecting a sunscreen, it is important not to focus solely on the SPF value, which indicates protection against UVB rays.

Consumers should also look for the circled UVA symbol on the packaging.

This symbol guarantees that the product provides balanced protection against UVA radiation thanks to the presence of specific filters capable of blocking the wavelengths primarily responsible for photoaging and deeper skin damage.

Comprehensive UVA and UVB protection is now considered essential for preserving the health and beauty of the skin over time.

Sun protection: a daily preventive measure

Sun protection should not be regarded as a product to be used only during summer holidays.

UVA rays are present throughout the year and can penetrate clouds and window glass. For this reason, dermatologists and skin care experts recommend applying adequate protection every day, especially to the face and other frequently exposed areas.

Taking care of the skin today means investing in its future health, helping to delay the appearance of visible signs of aging while maintaining its radiance, elasticity, and even tone.
