Sunscreens include some chemicals that can cause skin irritation such as redness, swelling, dryness, irritation, peeling of the skin, 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. PABAi  An organic compound that is used to generate vitamin B9 (folic acid) and treat certain autoimmune diseases.  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.

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.

Since we have discussed tips to prevent sunscreen side effects, let’s address a hot question: Is Oxybenzone in sunscreens harmful or safe? Scroll down to read.

Is Oxybenzone In Sunscreen Safe?

Oxybenzone is a common ingredient in sunscreens that helps shield the skin from harmful UVA and UVB radiation linked to skin cancer (7). It absorbs these rays, transforms them into heat, and releases them from the skin, reducing the risk of DNA damage (8).

However, oxybenzone is somewhat controversial due to claims of being a “potential hormone disruptor” (9). It is said to interfere with the endocrine system that regulates various biological processes. Yet, the clinical significance of these concerns remains inconclusive.

While some studies suggest possible issues, most sunscreens are generally considered safe for human health. Still, if there are worries, mineral filters can be a good alternative. Consult a dermatologist to check if oxybenzone will suit your skin type.
