| Answer: |
Most SPFs of 15 or higher will protect against both UVA and UVB rays. Known as broad-spectrum sunscreens, these products contain titanium dioxide. Other active sunscreens are zinc oxide, oxybenzone. While sunscreen helps to minimize damaging sunburns, it doesn't completely prevent tanning or burning and should be reapplied every one to two hours. |
| Answer: |
To be labeled “waterproof” or “very water resistant”, a sunscreen must maintain the same SPF level for 80 minutes in water or after perspiring.
Soon the word “waterproof” will be disappearing from package labels and may be replaced by the term “very water resistant”. The words “water resistant” on a label mean that the sunscreen maintains the same SPF level for 40 minutes in water or after perspiring.

UVA and UVB rays are different wavelengths of ultraviolet (UV) light from the sun. Both types are invisible and can cause skin cancer. UVA rays are the most plentiful. They penetrate into the deeper layers of the skin and can cause invisible photodamage, which may appear a few years later as lines, wrinkles or dark spots. UVA rays are not only responsible for aging effects; they can also contribute to sunburn and skin cancer. UVB rays are the primary cause for the redness and blistering of sunburns. Sun exposure can cause melanoma, one of the most dangerous types of skin cancer. |
| Answer: |
A wrinkle is defined as a crease or furrow in the skin caused by the natural process of aging, by excessive exposure to the sun's damaging rays, or environmental insults. For example, if you look in the mirror and see crow’s-feet around your eyes, these are wrinkles. If you stretch a wrinkle in the crow's-feet area, you will still see it. However, a fine line (or “expression line“) is a small wrinkle that may be caused by the contraction of facial muscles during smiling or frowning. When you stretch the skin of a fine line, the lines are barely visible. When these muscles contract, they pull the skin in, causing a line. And the muscles controlling frown lines between the brows may contract even when the muscle is resting, causing deep lines — which could result in the start of a wrinkle. |

To help protect your skin from the damaging rays of the sun, dermatologists recommend wearing a broad-spectrum sunscreen with a sun protection factor (SPF) of 15 or higher every day in all seasons…in summer and winter, on both cloudy and clear days. A broad-spectrum sunscreen helps protect your skin from both UVA (aging) and UVB (burning) rays. UVA rays are believed to be responsible for photoaging — the damage that occurs to the skin from many years of exposure to the sun. It's important to protect your skin from incidental sun exposure like while you're driving in the car, walking outside, etc.Apply sunscreen to all exposed skin, including lips, ears, backs of hands, and neck. Apply sunscreen generously and evenly before going in the sun, and reapply frequently after swimming, exercising, or sweating. It's also important to look for a sunscreen product that is water resistant. |
