Importance of sunscreen, its type, and homemade sunscreen recipes
Sunscreen is the essential part of your personal skin care routine. Exposure to the sun damages the skin. It can lead to many skin problems like wrinkles, premature aging, freckles, and blemishes. In addition to these problems, other effects can include sunburn and skin cancer. Sunlight consists of two types of harmful rays:
- Ultraviolet rays A (UVA)
- Ultraviolet B (UVB) rays
UVA rays (the rays of aging) are the longest rays in the spectrum, passing through window glass and penetrating deeper into the dermis, the thickest layer of skin. UVA rays can cause suppression of the immune system and damage at the cellular level that affects the immune system’s ability to protect the skin against the signs of aging. UVB rays are the shortest rays, which are blocked by window glass and are responsible for burns. These rays are also known as fiery rays.
The application of sunscreen is very essential to protect your skin from these skin problems. The sunscreen should be applied generously to the entire exposed part of your body 15 to 30 minutes before going out in the sun to allow enough time for absorption. The frequency of sunscreen application will increase in cases of excessive sweating and swimming and in humid and tropical climates. It should also be applied on cloudy days, as up to 80% of ultraviolet rays can pass through clouds. Applying sunscreen is beneficial for your skin if you apply it to areas that are not covered with clothing, even if you are not going to leave the house. An adequate amount of sunscreen can protect your skin from premature aging, freckles, and blemishes. People with sensitive skin should apply sunscreen with SPF-30 or higher, as their skin burns more quickly.
There are two types of sunscreen. One type of sunscreen that absorbs harmful UV rays is also known as chemical sunscreen, and another type of sunscreen blocks or deflects UV rays to prevent skin damage. These types of sunscreens are called physical (organic) sunscreens. The chemical screen contains chemical or synthetic filters. Chemical ingredients in sunscreen can degrade rays and render them ineffective. A safe alternative to chemical sunscreens is in the form of organic / natural sunscreens. Organic sunscreen contains plant ingredients that nourish and protect the skin. Zinc Oxide and Titanium Dioxide are the main ingredients in physical sunscreen that block / deflect the sun’s rays. Zinc oxide is quite safe for the skin, as the FDA has classified it as a category I product.
