Chemical sunscreens are a common type of sunscreen applied to protect the skin against the damaging ultraviolet (UV) rays. Chemical sunscreens do not sit on the surface of the skin like mineral sunscreens, but instead are absorbed into the skin and convert UV rays to heat, which is dispersed by the body. Although these products are useful in preventing sunburn and minimizing the risk of skin cancer, one should be conscious of the mechanism of action and the possible reactions they can trigger in certain people.
What are Chemical Sunscreens?
The active ingredients in chemical sunscreens include oxybenzone, avobenzone, octinoxate, and homosalate. These chemicals enter the outermost layer of the skin and create a barrier that absorbs UV radiations. This will aid in avoiding DNA damage which may result in early aging, sunburn and even skin cancers.
Common Symptoms and Responses
Even though chemical sunscreens are deemed safe to use by the majority of people, there are individuals who might develop skin sensitivity or allergies. The common symptoms are:
- Redness and irritation: In some cases, the skin can become red, itchy, or inflamed, especially when the person has sensitive skin.
- Stinging or burning: There can be a tingling or burning sensation, particularly around the eyes or on broken skin.
- Rashes or hives: The allergic reactions may appear as small bumps or hives, which may be a sign of sensitivity to one or more of the active ingredients.
- Hyperpigmentation: Prolonged usage may cause uneven skin complexion in sensitive persons.
In case you observe any of these symptoms, it is important to discontinue using the product and consult a professional.
When Should You Use Chemical Sunscreen?
The selection of the appropriate sunscreen should be based on your skin type, the level of activity and individual sensitivities. For example, people with sensitive or acne-prone skin can use alternatives like mineral sunscreens. Nevertheless, normal-skinned individuals who spend time outdoors tend to find chemical sunscreens to be lightweight, fast-absorbing, and water-resistant, which is convenient and effective.
