Side Effects of Sunscreen

Here are some of the side effects of sunscreen:

1. Allergic Reactions

Sunscreens include some chemicals that can cause skin irritation such as redness, swelling, irritation, and itching. Some people develop severe allergic reactions with rashes and intense itching. This allergic reaction can be the result of chemicals found in sunscreens like fragrances and preservatives. PABA is ideally used in many commercial sunscreens that can cause a high rate of allergic reactions. Hence, this is getting removed from many popular sunscreens of reputed brands(1), (2).

You can even buy sunscreens with the label ‘hypoallergenic’. Sunscreens that don’t contain PABA are often labeled, but some other chemicals can lead to an allergic problem (3). If you are not sure about the allergic reaction that may be caused by a sunscreen product, get a patch test done by a dermatologist. You can use sunscreens that contain zinc oxide, as they are less allergic.

2. Sunscreens Can Make Acne Worse

If you have acne-prone skin, some chemicals in the sunscreen product can worsen your problem. To get rid of this side effect of sunscreen, you can choose non-comedogenic and non-oily sunscreens. It is suggested to use a sunscreen best suited for your skin type. Avoid using body sunscreens on the face, as these are too heavy (4).

3. Eye Irritation

Getting sunscreen into the eye can cause pain and irritation. This can also lead to burning and temporary sensitivity to light. Some claim that chemical sunscreens can also cause blindness. If the sunscreen gets into the eyes, rinse them thoroughly with cool water or see your doctor (5).

4. Increases The Risk Of Breast Cancer

Sunscreen includes ingredients that can have estrogenic effects on breast cancer cells. Some sunscreens can have effects on blood estrogens levels. Avoid using chemical sunscreens on your children, as their skin tends to absorb the chemicals instantly (6).

5. Pain in Hairy Areas

There are varieties of sunscreen that can be confusing to choose from. They are also available in many forms like gels, lotions, sprays, ointments, creams, and wax sticks. It is your personal choice to choose the type of sunscreen. Gels are best for hairy areas like the scalp or the male chest. Some sunscreens can lead to tightening or drying of the skin and can cause pain in hairy areas.

6. Pus in the Hair Follicles

This is a rare side effect that occurs. However, it is not usually due to sunscreen. You need to consult a dermatologist immediately if you are experiencing any pain or discomfort.

Tips To Avoid The Side Effects Caused By Sunscreen:

  • Wash off and stop using the sunscreen if it causes redness or irritation.
  • Talk to your doctor or seek the pharmacist’s advice about using a new sunscreen.
  • Reapply sunscreen every 2 hours if you are outside for long periods.
  • If you are using the lip balm form of sunscreen, apply it on the lip area only.
  • Choose Sunscreen for your children very wisely.
  • Avoid using sunscreen on kids younger than 6 months.
  • Choose oil-free and non-comedogenic sunscreen if you have oily skin.

Sunscreen is an integral part of your skin care routine. However, not all sunscreens may be good for your skin. Some may cause serious side effects due to the ingredients used to make them. Sunscreens may cause allergic reactions, worsen acne, affect blood-estrogen levels, tighten your skin, and cause pus-filled blisters. You may have to follow the tips mentioned above to get rid of sunscreen’s side effects. It is always best to use chemical-free sunscreens to avoid allergic reactions. Always do a patch test before using any new product.
