When choosing sunscreen for sensitive skin, it's important to avoid certain ingredients that can cause irritation, allergic reactions, or clogged pores. One of the main culprits is fragrance—both natural and synthetic scents can be harsh on delicate skin, leading to redness or itching. Even if the product smells nice, added fragrance doesn’t provide any skin benefits and is best avoided if you’re prone to sensitivity.

Another group of ingredients to watch out for are chemical UV filters like oxybenzone, avobenzone, octinoxate, and homosalate. These ingredients absorb UV rays and convert them into heat, but they can also trigger allergic reactions or stinging sensations, especially around the eyes. Oxybenzone, in particular, has been linked to hormonal disruption and skin irritation in many cases.

Alcohol-based ingredients, especially denatured alcohol or SD alcohol, are also harsh on sensitive skin. While they’re sometimes used to help products dry quickly or feel lightweight, they can strip the skin's natural moisture barrier and cause dryness, flaking, or a burning sensation. It’s better to opt for sunscreens with hydrating, soothing ingredients like aloe vera, glycerin, or hyaluronic acid instead.

Lastly, avoid preservatives like parabens and methylisothiazolinone, which can provoke reactions in sensitive skin. Look for sunscreens labeled "mineral" or "physical" with active ingredients like zinc oxide or titanium dioxide. These ingredients sit on the skin's surface and reflect UV rays, making them less likely to irritate and ideal for people with sensitive or reactive skin types.
