Sun Block Lotion: Shielding the Skin from UV
Vitamin D is one of the important nutrients that can come primarily from the sun's rays. Exposing the skin to the sun for at least fifteen minutes a day can help in the production of Vitamin D, which is needed for the absorption of calcium and bone development. To get the natural Vitamin D at no cost, it is important to expose the skin to the sunlight. However, it is also important to note that overexposure to the sun's rays could lead to premature aging and sunburn. When the ultraviolet radiation could penetrate to the skin, mutation of DNA may occur. Skin cancer could develop from UV exposure.
To avoid sunburns and to prevent the skin from ultraviolet radiation exposure, it may be helpful not to go outdoors when the sun is up especially at midday and early afternoon. If wanting to get the Vitamin D from the sun, it may be wise to go out early in the morning when ultraviolet radiation may not be too intense. However, it is totally avoidable not to indulge in some activities particularly on a fine sunny day. To protect the skin from UV rays and to avoid getting sun burns, it may be helpful to apply sun block lotion.
Sun block lotion is one of the popular forms of skin protection from ultraviolet radiation. This topical product could contain ingredients which inhibit UV radiation to penetrate.
In choosing sun block lotions, it is significant to know the ingredients that could be helpful in blocking UV rays. Zinc oxide and titanium oxide are two compounds which have to be applied in some sun block lotions. These compounds are opaque materials and are known to be physical blockers of UVB and UVA. Chemical compounds are other ingredients of a sun block lotion which may have the property to block UV rays.
A sun block lotion is rated in SPF. The higher the sun protection factor it has, the more effective it can be in blocking UV radiations A and B. The lotion can be applied all over the body including the face. However, it is helpful to check if the lotion is safe to be applied on the face as some people may experience allergic reactions. It is then important to see a dermatologist about sun block lotion products for safety reason.
Sun block lotion could help in preventing sun burns. However, it is helpful to consult a dermatologist regarding the safety of a particular sun block lotion and its effectiveness to prevent sun burns and skin cancer.
