Protecting the skin from sun is vital in skin care routine. An overexposure to the sun can do a great deal of damage to the skin. It leads to sagging skin, wrinkles, sun burn, sun tan, heat stroke and also skin cancer.
Wear sunscreen as part of skin care, to protect the skin from these skin damages.
Sunscreens are the protective agents to prevent the sun’s ultraviolet rays from reaching the skin and minimizing the possibility of having skin problems.
The sun’s ultraviolet (UV) rays are in three forms: UVA, UVB and UVC. The UVA and UVB rays deeply penetrate the skin causing skin damages whereas UVC rays cannot penetrate the ozone layer.
The sunscreen can be a lotion , cream, gel or spray. Sunscreen lotion is well suited when exposure to the sun is more. Cream is best for less exposure.
The sunscreens contain an active ingredient called SPF for sun protection. SPF means sun protection factor that allows tanning with tolerable sun exposure. A sun protection factor tells how long the skin is protected from being burnt through UV rays.
This factor of sunscreens usually differs based on the skin type and the sun intensity. So, determine the right SPF factor easily using this equation. To use the equation, determine how long it normally takes for you to get burnt in the sun without protection. For instance, a light skin takes twenty minutes to produce redness on the skin. `
Now, multiply the time with the SPF of the sunscreen. In other words, multiply twenty minutes with the SPF 15 (an example) and find the result as three hundred. It is the time that the skin is protected from sun burn. So, with SPF 15, a light skinned individual can stay protected for about five hours.
It is very beneficial to wear sunscreens, especially in the summer time while going out.
However, most of the dermatologists are advising to wear sunscreens if you are going to expose to the sun more than twenty minutes. Also, they are recommending to wear sunscreen all through the year to stay away from skin cancer. As sunscreen can act as a barricade to solar radiation, wear sunscreen before thirty minutes of your sun exposure.
Selecting the sunscreen lotion is completely based on skin type. The sunscreens come in wide varieties to pick from. Knowing your skin type can help to select the right sunscreen. However, while selecting a sunscreen lotion, prefer broad spectrum sunscreens. This is because it protects the skin from the ultraviolet rays, especially the UVA and UVB rays. Also, ensure that it contains SPF (sun protection factor) 15 or more, as it indicates the goodness of sunscreen in sifting out the solar radiations.
Avoid sunscreen lotions that contain benzophenone, as it is absorbed easily by the skin and causes skin itchiness and allergies.
In addition to skin protection, lip care is also essential. So, wear sunscreen with lip salves. Sunscreen with SPF of thirty with broad spectrum is more efficient in protecting the lips from sun exposure.
As no sunscreen can give total protection, it is good to re-apply the sunscreen regularly for every two hours if you are swimming, sweating or exposing to sun extremely.
