RAD SHIELD Mineral Sunscreen SPF30

The main difference between UV-A and UV-B rays lies in their wavelength, penetration depth, and biological effects:

Wavelength: UV-A: 320–400 nanometers (longer wavelength) and UV-B: 280–320 nanometers (shorter wavelength)

Penetration: UV-A penetrates deeper into the skin, reaching the dermis. It's responsible for skin aging and wrinkling. UV-B primarily affects the outer skin layers (epidermis). It causes sunburn and can directly damage DNA, contributing to skin cancer.

Proportion in Sunlight: UV-A makes up about 95% of the UV radiation reaching the Earth. UV-B accounts for around 5%, but is more intense and biologically active.

Protection: Sunscreens and sunglasses usually specify whether they offer broad-spectrum protection, which means they block both UV-A and UV-B.

Protecting your skin from sun damage is crucial for preventing premature aging, sunburn, and skin cancer. Here are some simple, effective tips:

The #1 rule is to use sunscreen consistently on a daily basis. Rain or shine as UV rays are still harmful when the sun is not shining bright.

Choose a broad-spectrum sunscreen with SPF 30 or higher and reapply frequently. Apply 15–30 minutes before going outside and reapply every 2 hours or after swimming/sweating.

Seek Shade and avoid direct sun exposure between 10 a.m. and 4 p.m. when UV rays are strongest. Wear Protective Clothing such as Long-sleeved shirts, wide-brimmed hats, and sunglasses to help block UV rays. Look for clothes labeled with UPF (Ultraviolet Protection Factor).

Be Extra Cautious Near Water, Snow, and Sand. These surfaces reflect sunlight, increasing UV exposure. Avoid Tanning Beds as they emit harmful UV radiation that increases the risk of skin cancer.

Don’t Rely on Makeup Alone. Even if it has SPF, makeup usually doesn’t provide enough coverage—layer it over actual sunscreen.

Make a habit of checking the UV Index. Use weather apps or websites to monitor daily UV levels and plan accordingly.

Apply liberally and evenly to the face, neck and body before sun exposure. Reapply every 1-2 hours to maintain best protection especially after swimming, perspiring or drying off with a towel. recommended to use in combination with your daily Vitamin A step up skincare for best results and most effective protection.

SPF stands for Sun Protection Factor and UVB protection is measured/indicated by a product's SPF rating only. The number tells you how long the sun’s UVB rays will take to redden the appearance of your skin if you apply the sunscreen exactly as directed
compared with the same amount of time and same area of skin without sunscreen.
The minimum time it takes for reddening of the skin is referred to as
Minimal Erythemal Dose (MED).
