Ultra Light Daily UV Defense Aqua Gel SPF 50 PA++++

It is estimated that sunscreen with a level of SPF 50 is capable of filtering out around 98% of UVB rays, with approximately 2% reaching the skin. SPF 30, on the other hand, filters out 96.7% of UVB rays.¹ While the difference may seem insignificant, every boost of protection can contribute to the overall health and appearance of your skin.

The efficacy of an SPF 50 facial sunscreen generally lasts for up to two hours. If you are spending time indoors and away from direct sunlight, reapplication may not be required as frequently. However, during outdoor exposure or when engaging in activities that cause sweating, sunscreen should be reapplied more often, typically every two hours.

Kiehl's Ultra-Light Daily Facial Sunscreen has been created for all skin types, including sensitive skin. One of the key skincare ingredients in Ultra Light Daily UV Defense SPF 50 PA++++ is Vitamin E, which is typically used in moisturising skincare products to nourish the skin. This SPF 50 sunscreen is also formulated with glycerin - a well-known humectant that helps lock moisture into the skin, making it suitable for individuals prone to sensitivity and dryness.

Kiehl’s Ultra Light Daily UV Defense SPF 50 helps support anti‑ageing by protecting the skin from daily UVA and UVB exposure, which contributes to premature skin ageing. UVB rays primarily affect the skin’s surface and are associated with sunburn and visible photodamage, while UVA rays penetrate deeper into the skin and contribute to the gradual development of fine lines, wrinkles, uneven skin tone, dullness, dark spots, sun spots, and reduced elasticity over time. By providing broad‑spectrum SPF 50 protection, this sunscreen helps limit UV‑related skin damage when used consistently. As part of a daily skincare routine, ongoing use may help minimise the visible signs of ageing associated with sun exposure.

SPF 50 facial sunscreen should be applied every morning, approximately 20 minutes before sun exposure. For continued protection, sunscreen should be reapplied every two hours, or sooner if its efficacy is reduced by activities such as swimming, sweating, playing sport, or towel‑drying the skin.
