Sun Protection

Skin Seriously.


Sun Damage

Sun damage can be cause immediate effects such as sunburn (UVB rays) but can also cause damage which may not be immediately evident (UVA rays) wrinkles, age spots, broken capillaries, milia, and skin cancers. Even 1 sunburn or 1 time using a tanning bed can dramatically increase a person’s risk of developing skin cancer. There is no safe ultraviolet light and there is no safe way to tan.


Sun Protective Clothing

Aside from avoiding the sun particularly from 10 AM to 2 PM when the sun’s rays are the strongest, the safest sun protection is UV protective clothing. There are many companies that sell UV protective clothing. The degree of protection is measured in UPF rather than SPF units. Like sunscreens a UPF 30-50 is optimal. Umbrellas for the beach or at the pool are also helpful.



Sunscreens work by absorbing or reflecting the sun’s rays to protect you from damage. The SPF reflects the degree of protection against UVB rays (the burning rays). There is no accurate measure of UVA protection, but any sunscreen with broad spectrum coverage indicates it blocks against UVA. Sunscreen must be applied every 2 hours and more frequently if you are sweating or in water. An SPF 30 to 50 sunscreen is optimal. Higher SPFs do not add a significant degree of protection and tend to be much more expensive.

Sunscreens come in many forms and everyone should be able to find a sunscreen which they can use. Spray sunscreens are not sticky or greasy which is another reason people avoid wearing sunscreens. The best sunscreens for sensitive skin are chemical free containing only zinc and titanium. Stick sunscreens do not drip into children’s or athletes eyes which is a common complaint. Zinc containing sunscreens are best for people who tend to get dark marks on their skin when they are exposed to sunlight. Sunscreens with zinc and or genistein are best for people who have rashes due to sun exposure.
