Sun-Damaged Skin Prevention - People use sunscreens based on certain rules but recent scientific findings tend to counteract these. You need to update yourself about the use of sunscreens based on the recent findings.
Sunscreens are substances and materials that protect skin from ultraviolet radiation. They are available in the form of lotions, creams, gels, spray and ointments that can be applied to the skin. The list includes sticks that can be used on the nose and eyelids, sunglasses, moisturisers, certain types of sun protection clothing and film screens that can be fixed on the windows of cars, rooms and offices.
People have been using sunscreens for quite some time and are aware of the rules governing their usage, quantities to be used and how often to apply when you are out in the sun. Based on scientific studies, it is time to update knowledge on sunscreen usage strategies. Given below are some of the updates, contrasting the old knowledge with the current information.
- Old knowledge: Suggests one to apply a broad spectrum UVA/UVB sunscreen with SPF (Sun Protection Factor) 15, half an hour before leaving the house. The Current information is that in addition to SPF 15 one should add an antioxidant enriched moisturiser like idebenone, as the sun generates free radicals that break down collagen and elastin fibres.
- Old information: Putting on a T-shirt as a cover up to protect you from the sun is not good enough. Current information: Wearing dark colours and tightly woven fabrics at peak sunlight hours is necessary. Fabrics have UPF (ultraviolet protection factor) ratings and a 30 is required to meet the US Skin Cancer Foundation Seal of Recommendation.

The backs of the hands also face a lot of damage from holding the steering wheel. A non-stick spray can cover up these places and protect one fully.
- Old knowledge: being in the sun is healthy and 20 minutes of exposure three times a week allows the body to produce vitamin D. Current information: Vitamin D is necessary to keep bones healthy and boost the immune system, but supplements are the safest way of getting them, without exposing the body to the sun that could cause cellular damage, aging skin and cancer.
