Some people even suffer from serious allergic reactions like intense itching and rashes.  The allergic reaction can be caused due to the harsh chemicals found in sunscreen like preservatives and fragrances.

You can even purchase sunscreens that have a label, “hypoallergenic.” If you are not sure about the allergic reactions that may be caused by a sunscreen product, do a patch test done by a dermatologist. You can make use of sunscreens that contain zinc oxide, as they are less allergic.

Precautions to Follow while using a sunscreen

As there are so many side effects of sunscreen, you must follow some precautions while using the sunscreen. If any type of skin irritation or rash develops, stop using the sunscreen immediately and consult with your doctor. Sunscreen agents consist of aminobenzoic acid, padimate O, proximate, or lisadimate may lighten colored fabrics and make them look pale yellow.

Along with using sunscreen, you must not go out under the sun from 10 in the morning to 2 in the afternoon when the sun’s rays are at their strongest. Take extra care on overcast or cloudy days and when you are near reflective surfaces like sand, water, concrete, or snow, as these surfaces can show the sun’s damaging rays.

When you go out under the sun, make sure you wear protective clothing like a full-sleeved shirt, long pants, and a hat. You must also wear sunglasses to protect your eyes from any kind of sun damage. Avoid tanning parlors and sunlamps as these can cause harm to the eyes and skin.

Tips to Choose the Right Sunscreen

Always choose a sunscreen that comes with a “broad spectrum” protection. Sunscreens with this specific label protect against both UVA and UVB rays from the sun. Every sunscreen protects against UVB rays, which is one of the main causes of skin cancers and sunburn.

But UVA rays from the sun also contribute to premature aging and skin cancer. Very few products that pass through a specific test are labeled as “broad spectrum.” Products that do not fall under the category “broad spectrum” carry a warning. It says that they are only helpful in protecting against sunburn, and not just skin aging or skin cancer.

Ensure your sunscreen has a sun protection factor (SPF) of 30 or more. The SPF number is the level of protection which the sunscreen offers against the harmful UVB rays. The higher the SPF number, the more is the protection, but the higher you go, the small the disparity becomes.

SPF 15 sunscreens filter nearly 93% of UVB rays, whereas SPF 30 sunscreens filter nearly 97%, SPF 50 sunscreens nearly 98%, and SPF 100 about 99%. None of the sunscreens can protect you totally.

You must have come across water-resistant sunscreens. Keep in mind that water-resistant does not mean waterproof. None of the sunscreens available in the market are waterproof. If you find that a sunscreen’s label says itself to be water-resistant, then it must clarify whether it can last for 40 minutes or say, 80 minutes while sweating or swimming.

For achieving the best results, you must reapply sunscreen every 2 hours or more often if you sweat a lot or you are into swimming. However, you must be aware of the side effects of sunscreen before doing so. Generally, sunscreen rubs off when you dry yourself with a towel, so you need to put on a good amount of sunscreen.

The newer the sunscreen, the better will be the result. Before buying a sunscreen, make sure you check its manufacturing date. Sunscreen contains ingredients that get damaged quickly. Therefore, it is always better to buy fresh sunscreen. Try to buy one at a time instead of stocking it in your closet.

Always buy a creamy sunscreen rather than a powder or spray. Powder and spray sunscreens are mineral-based and consist of nanoparticles. These can get into our bloodstream which in turn can cause several health issues. Try to avoid such products and always buy cream-based sunscreens.

Now as you are aware of the side effects of sunscreen, keep these things in mind before applying sunscreen so that it will not affect your skin.
