Can Wrinkles Be Prevented?
Wrinkles that are due to UV damage of the skin can be reduced by the application of Sunscreens.
The best way to prevent sun-damaged skin and skin cancers and to reduce wrinkles in any case is to avoid episodes of excessive sun exposure, particularly during the hours of 10am to 4pm when sunlight pours down 80% of its total daily UV rays. Reflective surfaces, such as sand, concrete, and white-painted areas should be avoided.
Clouds or overcast coinditions do not filter harmful rays and therefore provide minimal protection and in some cases may intensify UVB rays. The intensity of UV rays depends on the angle of the sun, not heat or brightness. Sun lamps and tanning beds provide mostly UVA rays, and some experts believe that 15 to 30 minutes at a tanning salon are as dangerous as a day spent in the sun.
Sunscreens and sunblocks, used generously, represent an important part of anti-ageing skin care!
Any sunscreen should contain a wide spectrum of UVA-blocking ingredients, which include butyl methoxydibenzoyl-methane (also called avobenzone or Parsol 1789), dioxybenzone, oxybenzone, sulisobenzone, methyl anthranilate, octocrylene, and octyl methoxycinnamate or ethylhexyl p-methoxycinnamate. Assuming the same ingredients are used, inexpensive products work as well as expensive ones. Waterproof formulas last for about 40 minutes in the water, whereas water-resistant formulas last half as long. Sunblocks prevent nearly all UVA and UVB rays from reaching the skin, but to be fully protective they must contain zinc oxide or titanium dioxide.
