Which Ingredients to Avoid in Your Sunscreen
Sunscreen is essential for protecting your skin from the harmful effects of UV radiation. However, not all sunscreens are created equal. Some sunscreens contain ingredients that can irritate the skin, clog pores, or even cause long-term harm. Understanding which ingredients to avoid can help you make a safer, more informed choice for your skincare routine. Here’s a breakdown of the most common sunscreen ingredients to steer clear of.
1. Oxybenzone
Oxybenzone is a chemical sunscreen agent commonly used to absorb UV radiation. While it is effective at protecting the skin from UV rays, oxybenzone has been linked to skin irritation, hormone disruption, and allergic reactions. It can also be absorbed into the bloodstream, which raises concerns about its potential long-term effects on health. For individuals with sensitive skin or those looking to avoid chemical exposure, oxybenzone is best avoided.
Why to Avoid:
-
Can cause skin irritation and allergic reactions.
-
Absorbed into the bloodstream, raising health concerns.
-
Linked to hormone disruption.
2. Avobenzone
Avobenzone is another chemical sunscreen agent that absorbs UVA rays. Though it is effective, avobenzone can break down quickly when exposed to sunlight, making it less stable than other sunscreen ingredients. This instability can reduce the overall effectiveness of the sunscreen, meaning you may not get the full protection you expect.

Why to Avoid:
-
Instability in sunlight can reduce sunscreen effectiveness.
-
May require frequent reapplication to ensure proper protection.
3. Homosalate
Homosalate is used in many sunscreens to help absorb UVB rays. However, it has been identified as a potential hormone disruptor. It can also be absorbed through the skin and accumulate in the body over time. Although more research is needed, it’s better to err on the side of caution and avoid sunscreens with homosalate, particularly if you have sensitive or acne-prone skin.
Why to Avoid:
-
Potential hormone-disrupting effects.
-
Can accumulate in the body over time.
4. Octinoxate (Octyl Methoxycinnamate)
Octinoxate is another common sunscreen ingredient that absorbs UVB rays. However, this ingredient has raised concerns due to its potential to disrupt hormones and impact coral reefs. It can also irritate sensitive skin and cause allergic reactions. Additionally, like other chemical sunscreens, octinoxate can be absorbed into the bloodstream, which is why many people with sensitive skin opt to avoid it.
Why to Avoid:
-
Linked to hormone disruption.
-
Potential environmental impact (harmful to coral reefs).
-
Can irritate sensitive skin.
5. Octocrylene
Octocrylene is used in sunscreens as a stabilizer and UV filter. While it is effective, it can cause skin irritation and may clog pores, which can lead to breakouts. Additionally, it has been found to accumulate in the skin over time, which raises concerns for long-term use. People with sensitive or acne-prone skin should avoid sunscreens that contain octocrylene.
Why to Avoid:
-
Can cause skin irritation and breakouts.
-
Has the potential to clog pores.
-
May accumulate in the skin over time.
6. PABA (Para-Aminobenzoic Acid)
PABA was once a popular sunscreen ingredient, but it is now rarely used due to its potential to cause skin irritation, allergies, and sensitivity to the sun. While it is effective at blocking UVB rays, PABA can cause redness, itching, and even staining of clothes. Many people with sensitive skin choose to avoid sunscreens containing PABA for a more gentle, non-irritating option.
Why to Avoid:
-
Can cause allergic reactions and skin irritation.
-
Can increase sensitivity to the sun.
-
Stains clothing.
7. Fragrance
Fragrance is commonly added to sunscreens to enhance the scent, but it can be a significant irritant, especially for sensitive skin types. Fragrances, whether synthetic or natural, can cause redness, itching, and allergic reactions. If you have sensitive skin or are prone to eczema or other skin conditions, it’s best to avoid sunscreens with added fragrance.
Why to Avoid:
-
Can cause skin irritation and allergic reactions.
-
May exacerbate existing skin conditions like eczema or rosacea.
-
Often contains synthetic chemicals that can irritate the skin.
8. Parabens
Parabens are preservatives commonly used in cosmetics and sunscreens to extend shelf life. However, parabens are known endocrine disruptors, meaning they can interfere with hormone function. They have been linked to health problems such as reproductive issues and an increased risk of breast cancer. For safer skincare, opt for paraben-free sunscreens.
Why to Avoid:
-
Known endocrine disruptors.
-
Can cause hormonal imbalances.
-
Associated with an increased risk of certain cancers.
9. Butyl Methoxydibenzoylmethane (also known as Avobenzone)
While avobenzone is a good UV filter, it’s often combined with other chemicals that can make it less stable, especially in the presence of sunlight. It is prone to degradation, which reduces the effectiveness of the sunscreen over time. This instability makes it less ideal for prolonged sun exposure.
Why to Avoid:
-
Less stable and can degrade quickly in sunlight.
-
Reduced effectiveness over time.
Conclusion
When selecting sunscreen, it’s essential to be aware of the ingredients that may cause irritation or health concerns. Oxybenzone, octinoxate, homosalate, and PABA are just a few ingredients that can cause skin irritation, hormone disruption, or environmental damage. Opting for mineral sunscreens with ingredients like zinc oxide and titanium dioxide can provide effective, gentle protection without the risks associated with chemical sunscreens. Always check the ingredients list and choose sunscreens that align with your skin’s needs to ensure both protection and safety.
