That’s right—not all skin care products are safe to use while you’re pregnant. Common items to avoid include topical retinoids1, high-dose salicylic acid (found in peels and oral medications), and oxybenzone (commonly found in chemical sunscreens). Although, London-based dermatologist Aamna Adel, MBBS, MRCP, took to TikTok to share one “underrated” chemical exfoliant that is pregnancy-safe: azelaic acid. Adel considers azelaic acid an underrated pick because it can help ease many of the same skin concerns as other chemical exfoliants. Specifically, azelaic acid has the power to treat acne, post-breakout inflammation, and rosacea, and it’s safe to use during pregnancy, according to the American Academy of Dermatology. Not to mention, studies have shown azelaic acid to be a comparable acne treatment to certain retinoids. In one study of comedonal acne2, 20% azelaic acid cream was equally as effective as 0.05% tretinoin cream in reducing the number of comedones and with respect to the overall response. What’s more, azelaic acid cream was better tolerated and caused fewer local side effects (think irritation, dryness, and redness) than the topical retinoid. Clinical studies have shown that azelaic acid is also effective at treating rosacea3. Suffice it to say, we agree that this chemical exfoliant is underrated in the skin care space, especially for those who are pregnant. If you’re looking for an OTC product, we recommend the Naturium Azelaic Acid Emulsion or The Ordinary Azelaic Acid 10% Suspension Cream. If you’re looking to treat acne, you might want to see a dermatologist first, as you may need a prescription-grade product with a higher concentration to see results.
