What is Mederma Spf 30? Uses, warnings & side effects

Most sunscreens are applied about 15 to 30 minutes before you go out into the sun. Sunscreens that contain PABA should be used about 1 to 2 hours before sun exposure. There are many different kinds of sunscreens, so instructions may change with each product. Always read and follow the instructions on the package label.

Use the sunscreen on your skin only. Do not get it in your eyes, nose, or mouth. Do not use the spray on your face. A sunscreen stick or lip balm especially made for your face is easy to use.

Apply a thick layer of sunscreen to all skin areas exposed to the sun. Reapply the sunscreen at least every 2 hours or more often, or after swimming, towel drying, or heavy sweating.

If the sunscreen contains alcohol, you should not use it near a fire or if you are smoking.

Topical application routeAsk your pharmacist or doctor how to dispose of the medicine container and any leftover or expired medicine.

Keep all medicine out of the reach of children. Never share your medicine with anyone.

Talk with your doctor if you have had an allergic reaction to a sunscreen. Even if you have had an allergic reaction to one sunscreen, you still may be able to use another sunscreen that contains different ingredients.

Sunscreens work by either absorbing or reflecting the sun's ultraviolet radiation (UVR). UVR causes skin cancer, sunburns, and premature aging of the skin (wrinkles and dry, thinning skin). Clouds will filter some UVR, but not all. You will still need to use sunscreen even when it is cloudy.

You should not use sunscreens on children younger than 6 months of age without checking first with your child's doctor. Children younger than 6 months of age may absorb sunscreen through their skin into their bodies. It is best to keep babies younger than 6 months of age out of the sun. If this cannot be avoided, lightweight clothes and a hat may help protect a baby from the sun.

To prevent skin damage, avoid being in the sun between the hours of 10 AM and 3 PM, when the sun's rays are strongest.

Sunscreens are rated by SPFs (sun protection factors). Use a sunscreen with an SPF of at least 15. Children older than 6 months of age should wear a sunscreen of broad spectrum and with SPF 15 or higher when outdoors. If you need more protection or have fair skin, an SPF of 20 to 30 (or higher) can be used. You can also protect your skin by wearing a hat, sunglasses, and lightweight clothes.

UVR can reflect off of light surfaces such as sand and snow. Wear a sunscreen when you are out in the snow to keep from getting a sunburn.

Sunscreens that contain PABA may permanently stain your clothing yellow.
