Even though the Sun powers our lives, and is an essential component of our sustenance, a slight rise in temperature or increased glare can make life uncomfortable. Every Summer, owing to a heat wave in India, temperatures soar all over the country and people feel the heat and are curious about the adverse effect that sunlight has on skin.
Photo aging and higher UV exposure
UV radiation, which is a part of the spectrum of light emitted by the sun, consisting of UVA & UVB rays, is considered to have a significant impact on the skin upon prolonged exposure on a daily basis. The UVB rays are partially absorbed by the ozone layer covering the Earth. In recent years, the ozone layer has been depleted steadily because of increased emission of Green House Gases. Thus, more UVB rays are hitting the skin than ever before. UVB rays are responsible for such skin conditions as melanoma, basal cell carcinoma and certain types of skin cancers. UVA rays cause a phenomenon known as ‘photo aging’, or premature skin aging due to sun damage. Long term exposure to UVA rays can cause skin cancer, sun allergies and other phototoxic reactions. UVA radiation penetrates deeper into human skin than UVB rays, even inside the dermal layer, to cause dryness, wrinkles and spotting. UVA radiation, may also generate free radicals, damage the lipids and proteins in the skin, and hasten the onset of photo aging. The penetration of UVA rays inside the skin does not have immediate visible effects, but the damage is long term.
Protecting the skin from photo aging
Wearing protective clothing and liberal amounts of sunscreen with an optimum SPF factor and PA factor can stop photo aging in its tracks. Contrary to popular perception, being indoors does not necessarily help – UVA rays can penetrate glass. Therefore, as long as you are exposed to bright light for an extended period of time, it is advisable to also put on sunscreen. But your skin needs its own personal UVA and UVB barrier which can guard you against elastin.
The fundamental elements of the dermis, the elastic fibers – which are mostly made up of elastin and provide the skin with its biomechanical properties and firmness – are particularly affected by sunlight. BASF Beauty Creation experts discovered a process triggered in response to UV light which upsets the balance of these fibres: too much elastin and too little LOX-L enzyme to assemble it into functional elastic fibres. This imbalance then leads to accumulation of non-functional elastin, which groups together in aggregates and cannot be naturally removed. The skin loses its elasticity, lines deepen and run together: this is known as solar elastosis.
With our expertise in elastic fibres, we have designed a witch-hazel leaf extract that stimulates LOX-L, restoring the balance and thus the cycle of functioning elastic fibre synthesis. In addition to the sun protection of UV filters, Lys’Sun™ preserves the skin from the imbalances caused by sunlight and helps restore its youthful appearance, repairing damage to fibres in the dermis. Lines are reduced and the skin recovers its firmness.
Regular use of Lys’ Sun reverses the effects of solar elastosis, and also removes fine lines. The cream restores the skin’s elastic fibres by preventing harmful UVA rays from disrupting the processes of skin renewal.
Sun protection applies to people from all ages, genders and nationality wishing to keep their skin healthy. BASF offers 360⁰ all rounded high efficient sun protection solutions. We provide an extensive array of top quality UV filters (Tinosorb® and Uvinul®) together with other cosmetic ingredients for sunscreen formulations. No one needs to hide under the sun any longer.
