Sunscreen. What’s the difference between a physical and a chemical sunscreen? Which is better? Does sunscreen really cause cancer?
There are two kinds of sunscreens: physical and chemical. Physical sunscreen reflects the sun’s rays away from the skin using white pigments, whereas chemical sunscreens absorb the rays to themselves and turn them into thermal energy. Chemical protection is achieved by synthetic compounds – physical sunscreen is obtained from nature. Physical sun protection works immediately after application and doesn’t fade but chemical protection requires about 20 minutes before working and you have to reapply it since it fades in the UV-light.
Many are sensitive to sun lotions and in most of the cases the cause is chemical compounds. Titanium dioxide used in natural organic cosmetics is less allergenic and therefore physical sunscreen may be better for sensitive skin. Physical sunscreens can also contain zinc, which isn’t considered a sunscreen agent anymore but is a great ingredient to the skin anyway. It protects and heals the skin and works for acne and baby skin.
I’ve used both chemical and physical sunscreens and needless to say the chemical ones tend to be nicer to use. They are lightweight, they absorb quickly and they don’t leave a white cast. But they can clog pores and irritate the skin. The Internet is controversial about their impact on human health and the natural environment and there are even some studies that say they can cause breast cancer. So considering all the pros and cons I would prefer physical sunscreen over them. Physical suncreens are safer, less allergenic and more efficient.
Biosolis is a certified organic sun protection line. They have products with light protection (SPF6 Oil) and products with higher SPF all the way to SPF50. My favourite product from them is Sun Milk with SPF15. It’s a light fluid so it’s easy to apply and it absorbs quickly. It still offers a great protection and I didn’t burn myself once using this in Rhodes. At first I just used the lotion all over my face and body but now I’ve switched to using the Face Cream with SPF30. It’s thicker than the SPF15 but offers even more effective protection. Physical sunscreens such as these need some time to absorb and they feel a bit sticky at first. After a while they are absorbed into the skin and do not leave a white cast. They are waterproof and I haven’t had to reapply these during the day. It’s quite nice actually since I don’t have to worry about sunscreen during the day. I just have to apply it once in the morning.
These sunscreens contain all natural ingredients besides the obvious zinc and titanium oxide. The basis is made from Aloe Vera which is a great ingredient for all skin types. It soothes, moisturises and is suitable for oily skin as well. The products also contains natural oils such as karanjula oil and sunflower seed oil. These Biosolis sunscreens were sent to me for my trip in Rhodes and I’ve been using them almost every day after that. Out of these three my favourites are the SPF30 and the SPF15.
