不含防腐剂的防晒霜

PABA (Para-Aminobenzoic Acid) and parabens have traditionally been used in sunscreens for their UV-filtering capabilities and preservative properties, respectively. However, with growing concerns over skin sensitivities and the potential health risks associated with these chemicals, the demand for safer alternatives has risen.

A significant portion of individuals with allergic contact dermatitis show reactions to PABA and parabens. Studies suggest that around 4% of people with this condition test positive for allergies to parabens. While less common today due to reduced usage, PABA-related sensitivities were once more prevalent.

For those with allergies to PABA and parabens, it's essential to be aware of other preservatives used in sunscreens that might cause cross-reactions. Certain chemicals, such as benzophenones and cinnamates, can act similarly to PABA, while some preservatives may share properties with parabens. We'll explore which substances to steer clear of to ensure your sunscreen is truly safe for your allergy-prone skin.

If you are allergic to parabens, here is a list of other preservatives in sunscreen that you can use. Note that all of these do not meet clean beauty standards but are alternatives to parabens if you are paraben allergic:

Ethylhexylglycerin - A mild preservative derived from glycerin, ethylhexylglycerin is not only effective against bacteria but also enhances the skin feel of products, making it a popular choice in clean beauty formulations.

Phenoxyethanol - Recognized for its broad-spectrum antimicrobial properties, phenoxyethanol is a commonly used alternative in clean beauty products to protect against bacteria and fungi, though used in concentrations deemed safe (typically under 1%).

Vitamin E (Tocopherol) - Often used for its antioxidant properties, Vitamin E can also help preserve the integrity of a product by protecting it from oxidation, a natural process that can degrade sunscreen ingredients over time.

Natural Extracts - Certain clean beauty brands might utilize extracts from plants with preservative properties, such as grapefruit seed extract (Citrus Grandis) and rosemary extract (Rosmarinus Officinalis), which offer antimicrobial benefits and can contribute to the product's overall effectiveness and stability.

Caprylyl Glycol - An alcohol derived from caprylic acid, caprylyl glycol is used for its antimicrobial properties and as a humectant and skin conditioning agent, often found in formulations that prioritize safer, more natural ingredients.

Sorbic Acid and Salicylic Acid - These organic acids are sometimes used for their antimicrobial properties, protecting products from spoilage and extending their shelf life.
