Application of sunscreens with a sun protection factor 30 (SPF30) prior to exposure to sunlight is likely to delay the onset of skin cancer, finds a new research.

The study, conducted on mice, showed that sunscreens are known to prevent skin from burning when exposed to UV sunlight, which is a major risk factor for melanoma — most serious form of skin cancer.

However, it has not been possible to test whether sunscreens prevent melanoma because these are generally manufactured as cosmetics and tested in human volunteers or synthetic skin models.

“We have developed a mouse model that allows us to test the ability of a sunscreen to not only prevent burns but also to prevent melanoma,” said lead researcher Christin Burd, assistant professor at the Ohio State University.

“This is a remarkable accomplishment. We hope that this model will lead to breakthroughs in melanoma prevention,” he added.

Burd and colleagues previously reported in Cancer Discovery, a journal of the AACR, the development of this mouse melanoma model.

The researchers genetically engineered mice and found that if they exposed these to a single dose of ultraviolet-B (UVB) light one day after applying the SPF30 chemical 4-hydroxytamoxifen (4OHT) to the skin, melanomas appeared much more rapidly, and there were many more tumours.

The researchers then used the mouse model to test the ability of a number of sunscreens labeled SPF30 to prevent melanoma.

The sunscreens, which contained a range of UV-blocking agents, were applied to the mice prior to exposure to the UVB light. All the sunscreens delayed melanoma onset and reduced tumour incidence.

“Melanoma-free survival was reduced by 80 percent, to about five weeks,” said Burd.

There are ample brands offering sunscreens in different forms, but you need to know your skin type before you spend a hefty amount on the product. So, make sure you buy the right kind of sunscreen, say experts.

Aashmeen Munjaal, celebrity make-up artist and Bharti Taneja, Director of Alps Beauty Clinic and Academy have shared some tips:

* Sun protection creams for face have to be of really fine quality. Rather than going for too many sun block creams, you need to choose light weighted mist spray and have a thin layer. For your body you can use thick layered sunscreen.

Lotions and sun-guards containing SPF (Sun Protection Factor) 20 to 35 are suitable for Indian skin types.

The rays of the sun affect the fair complexion easily. Lotions having SPF 30 is the best for people having a fair or wheatish complexion. In case you have a dark complexion, you should opt for lotions that contain SPF 20.

If you reside near the coastal regions or are going on a vacation to the beach, you should choose a sunscreen lotions containing SPF 30 to 50.

Sometimes for buying that sun screen you need to pay extra which equally hit your pockets. But after 50 SPF all sun screen are same in their effects.

* There are sunscreen lotions that are waterproof or water-resistant, which means that after the application of the lotion, even if you wash your face with water, the lotion will not wear off.

Waterproof sunscreen lotions will last up to 80 minutes in water and water-resistant sunscreen lotions can last up to 40 minutes in water. These kind of sunscreen lotions are best for swimmers.

* You need to identify if your skin is allergic to certain sunscreen. Different sunscreens have different ingredients so don’t be afraid of trying new sun screen.

* If you have oily skin make sure you use gel based sunscreen or sun foundations — soufflé based, mousse based, powder based and water based.

If you have very dry skin, you can blindly go for oily sun screen which has some greasy or oily effect in it. It will eventually hydrate your skin besides protecting you from the sun.

For sensitive skin, avoid aphelia ingredients in skin. Also test the product on your skin at the back of your ear lobe. If there is no reaction you can continue with same sun screen. (Bollywood Country)
