In and Out of Sunscreen Uses: How Much, How Often and More

The harmful effects of UV rays (UVA and UVB) are known to all. UVA can prove to be a great nemesis for flawless skin, accelerating the skin ageing process. The skin loses its radiance and appears saggy and wrinkled. UVB affects the skin superficially, resulting in sunburns and skin tans. At times, overexposure to UV rays can produce Carcinogenic (skin cancer) effects. Use of a good quality sunscreen is more of a necessity than luxury. The effectiveness of a sunscreen can be enhanced several folds if one knows the ins and outs of its use.

1. Sunscreens with different SPF (Sun Protection Factor) numbers are available in the market. SPF provides intense protection from the UVB rays. An overall skin protection can only be achieved when the harmful effects from both UVA and UVB can be controlled and minimised. Do not judge a sunscreen by its price tag. An expensive sunscreen is not necessarily an effective sunscreen. Go for the sunscreen that covers a Broad Spectrum.
2. Many people do not get the usage of the sunscreen right. Sunscreen cannot work miracles. Applying it only once a day will not solve the purpose. Often, your work might require you to be in the sun for a longer period of time. Under such circumstances, use the sunscreen every two to three hours.
3. Application of sunscreen at regular intervals is also effective for people who are more into swimming and water related activities. This usage is beneficial for people who sweat profusely. For sensitive skin, it is best to consult a dermatologist before using any sunscreen.
4. Applying excess amounts of sunscreen will not provide your skin with any extra protection. A generous quantity of sunscreen can also do the trick. The quality matters more than the quantity.
5. Sunscreens can be Mineral (Zinc Oxide and Titanium Oxide) or Synthetic (Oxybenzone, Avobenzone) active. In case of Mineral sunscreen, one can step outside immediately after its application.
6. In case of synthetic sunscreen actives, immediate exposure to sunlight might fail to provide the desired protection. For better results, apply the sunscreen 25 - 30 minutes prior to an outside venture.
7. Being at home does not guarantee protection from sunrays. You can still be susceptible to the harmful UV rays. Use sunscreen daily, even when at home.
8. If you are into makeup, use sunscreen once you are fully done with the makeup.
9. Sunscreen is not only meant for bright, sunny days. This misconception can affect your skin in the long run. Apply sunscreen regularly, irrespective of the weather outside.

Sunscreen, if used accurately will keep a lot of skin problems and sunburns at bay.
