The sun, the silent cause of skin aging

Skin aging—premature aging of the skin caused by sun exposure—is responsible for about 80% of the visible signs of aging : wrinkles , loss of firmness, pigment spots , uneven skin tone.

The cause is ultraviolet (UV) rays. There are two main types:

UVB rays are the cause of sunburn. Their action is immediate but superficial.

UVA rays penetrate deep into the skin. They damage collagen and elastin fibers, generate oxidative stress, and cause micro-inflammations that ultimately degrade skin quality. All this without pain or redness, but with lasting effects.

It is this chronic exposure to UVA rays — even moderate — which, over the years, visibly accelerates skin aging.

Facial sunscreen: an essential ally for preserving the skin's youthfulness

Applying sunscreen with SPF 50 daily is one of the most effective ways to slow the appearance of signs of aging. Good protection:

• Preserves collagen and elastin by blocking UVA rays.
• Limits cellular oxidation , avoiding the overproduction of free radicals
• Prevents the appearance of pigment spots , which indicate a disruption of melanin.
• Protects sensitized or weakened skin, particularly after dermatological treatments or in cases of pigmentation disorders such as melasma.
  
  

A routine to adopt all year round, even in the city

UVA rays are present all year round, whatever the weather: they pass through clouds and windows and are active 365 days a year. This is why applying a broad-spectrum (UVA + UVB) facial sunscreen every day is recommended, in summer and winter, at the seaside and in the city.

This gesture is not reserved for long exposures: everyday light is enough to impact the skin — walking in the street, working near a window, driving… All these moments expose the skin, sometimes without us being aware of it.

This is why it is recommended to apply SPF every morning , even outside periods of direct exposure.

However, there's no need to change your entire beauty routine: at Aime, we've designed an SPF moisturizer that's effective, gentle, and sensory , and will easily fit into your skincare routine . Its fluid, non-greasy texture, invisible on the skin, allows for easy application before makeup . Thanks to its hydrating active ingredients, the Daily SPF Care can be applied directly after your serum and replace your day cream. A gesture that quickly becomes a new reflex—and one that pays off in the long run. Because effective sun protection can (also) be pleasant to wear!
