Sunscreen is vital for protecting the skin from harmful UV rays. However, for individuals with sensitive skin, choosing the right product can be difficult. While sunscreens are generally safe, some people may experience redness, itching, or rashes after use. In some cases, sunlight exposure combined with certain sunscreen ingredients can trigger allergic reactions or skin sensitivity.

The symptoms of sun allergy are:

  • Red, itchy rashes
  • Hives
  • Swelling
  • Scaling
  • Pain
  • Blisters
  • Raised bumpy areas

Types of Sunscreens: Chemical vs Physical

Chemical sunscreens absorb UV rays and convert them into heat through a chemical reaction, reducing their harmful effects. Ingredients like oxybenzone and avobenzone are commonly used but may irritate sensitive skin.

Physical (mineral) sunscreens, containing zinc oxide or titanium dioxide, sit on the skin’s surface and deflect UV rays. These often leave a white cast and are frequently used by athletes, like cricketers, on sun-exposed areas.

Sunscreens Can Be Of Two Types:

Chemical Sunscreen: These types of sunscreens absorb the UV radiation and alter the rays of the sun into less harmful ones. The active ingredients cause a chemical reaction that converts the UV light into heat making it less harmful to the skin.

Physical (Mineral) Sunscreen: These sunscreens block and deflect the rays from the skin. It gives a whitish appearance. It is commonly applied by cricketers on the nose and cheeks.

Contents In The Sunscreen That One May Be Allergic To:

  • One of the most common ingredients in sunscreens is called Oxybenzone. Oxybenzone is an endocrine disrupting chemical which means it is a chemical that disrupts the hormones in your body. It is responsible in clinical trials for increased rates of melonoma. It is also linked to hormone disruption, allergies, cell damage and skin cancer.
  • Avobenzone: It breaks down into free radicals on exposure to sunlight which accumulates in the body. This accelerates the aging process and increases the risk of harmful illnesses such as cancer.
  • Octinoxate: It is readily absorbed by the skin. It is known to cause hormone disruption. It can cause premature aging as it produces free radicals that can damage skin and cells.
  • Retinyl Palmitate: When exposed to suns UV rays, the retinol compounds break down and produce destructive free radicals that are toxic to cells, damage DNA, and may lead to cancer.
  • Homosalate: It accumulates in our body, becomes toxic and disrupts our hormones.
  • Valates: They are dangerous compounds that affect fertility.
  • Parabens: They are commonly used as preservatives. They can induce allergic reaction, hormone disruption, developmental and reproductive toxicity.
  • Fragrances: There are various artificial chemical fragrances added to make the sunscreen smell good which may not be beneficial to us.

Some Helpful Tips And Tricks:

- Always do a patch test before using any new sunscreen or product on the skin. If you do not see any allergy symptoms within a day you are not allergic to that sunscreen.

- In case you observe any itchy sensation or redness or rash immediately wash off the product.
