New tips and tools to keep skin beautiful all year long

 

Sunblocks and sunscreens: Sunscreens chemically absorb UV rays, sunblocks physically deflect them. Sunscreen has long blocked UVB effectively, but until recently provided less UVA protection. New ingredients such as octylcrylene and the benzophenones have improved sunscreen's defenses against shorter UVA rays, and the revolutionary chemical avobenzone (Parsol 1789) works against all UVA wavelengths.

Sunscreens that say "broad-spectrum" can protect the skin from both UVA and UVB rays. Sunscreens come in lotions, gels, creams, and ointments. *Triple digit SPF

SPF 100 is in the market now! Doctors say the difference in protection between SPF 30 and 100 is negligible, others argue every little bit helps. Most people do not use enough sunblock (about a shot-glassful for the body) as often as 2 hours.

 * The Sweat Factor
Perspiration glistens, so it attracts more light onto skin. It also washes regular sunscreen off the skin. Comparison shows that those who wore water-and sweat-resistant SPF 70 had no burn after four hours, unlike those using a classic SPF 15. *Your TimetableLotions with chemical sunscreen , need to be applied 30 minutes before stepping in the sun. If you need immediate defense, opt for physical blockers such as zinc oxide.  Ultraviolet light rays (UVA and UVB)The sunlight that reaches the earth has ultraviolet A and ultraviolet B (UVA and UVB) rays. These ultraviolet rays are the main causes of damage to the skin from the sun. UVA and UVB rays affect the skin's sensitivity to sun exposure in different ways.  UVA: ·         Can pass through window glass. ·         Is not affected by a change in altitude or weather. ·         Is present all day and every day of the year. ·         Penetrates deep into skin layers. ·         Is 5% of the sun's rays. ·         Is 20 times more abundant than UVB rays. ·         Affects long-term skin damage. UVB: ·         Cannot pass through window glass. ·         Causes sunburn. ·         Causes tanning. ·         This ray only has the strength to penetrate the epidermis.·         Helps the body with normal vitamin D production. ·         Varies with the season. It is more intense in the summer than in the winter. ·         Varies with weather conditions. ·         Is more intense at midday than in the morning or late afternoon. ·         Is more intense at high altitudes and near the equator. ·         Is 0.5% of the sun's rays. ·         Is protected against by the sun protection factor (SPF) in sunscreens. ·         Is related to more than 90% of nonmelanoma skin cancer.
