Leti AT4 Atopic Skin Defense Photoprotect SPF50 is a daily sun protection product specially formulated to meet the needs of atopic skin, characterized by a weakened skin barrier and increased sensitivity to environmental agents. Its formula incorporates a combination of photostable sunscreens that provides very high SPF50 protection against UVB radiation and broad-spectrum protection against UVA rays. In addition, it helps protect the skin from the effects of infrared A (IR-A) radiation and high-energy visible light (HEVL), factors associated with oxidative stress and skin aging. Apply generously to dry or damp skin before sun exposure. Reapply frequently, especially after swimming, heavy sweating, or towel drying, to maintain the level of protection. Avoid contact with eyes. Babies and young children should be kept away from direct sunlight. An insufficient amount of product significantly reduces the level of protection. The exclusive Pro-Caspase-14 System Complex technology helps stimulate the synthesis of filaggrin and caspase-14, proteins essential for the integrity of the skin barrier and for the skin's natural photoprotection mechanisms. This action helps reduce the vulnerability of atopic skin to sun exposure and aids in preventing damage induced by UV radiation. The formula is enriched with Shea Extract, recognized for its antioxidant properties, helping to neutralize free radicals and protect the skin against oxidative stress caused by sun exposure, pollution, sand, perspiration and other external agents. Its texture adapts to application on dry or wet skin, spreading easily and providing comfort without compromising the effectiveness of sun protection. It is suitable for daily use by the whole family, including babies, children and adults with atopic or very dry skin. The product is hypoallergenic, paraben-free and tested under dermatological and pediatric control.
