The Great Retinoid Debate: Are They Safe for Pregnant Women?
In the world of skincare, retinoids have become a hot topic, but when it comes to pregnancy, the advice gets murky. With so many conflicting opinions, it's no wonder expectant mothers are left confused.
Pregnancy is a time of overwhelming advice, from what to eat to what medications to avoid. Skincare, however, seems to be a grey area. While some products are deemed safe, others are a big no-no. Enter retinoids, a family of ingredients that have skyrocketed in popularity, but are they safe during pregnancy?
Retinoids are like the superheroes of skincare, tackling everything from acne to wrinkles. But here's where it gets controversial: these powerful ingredients have different forms, and their safety during pregnancy varies.
Understanding Retinoids
Retinoids are essentially derivatives of vitamin A, and they're the go-to ingredients for a multitude of skin concerns. "They're the gold standard," says Michelle Wong, a chemist and science communicator. But what exactly are these retinoids, and how do they work?
The most potent retinoids are prescription-only drugs like isotretinoin (taken orally) and tretinoin (applied to the skin) for severe acne. Then there are pharmacist-only products with adapalene, and the more accessible "over-the-counter" retinoids like retinal and retinol, which are found in topical creams at lower concentrations.
The Safety Debate
It's widely accepted that oral retinoids are a big no-no during pregnancy due to the risk of birth defects. This warning is clearly stated on packaging and drug information leaflets. But what about topical retinoids? Here's where the advice gets confusing.
NSW Health's Mothersafe advises that OTC retinoid creams are safe for pregnant women due to their topical application and lower doses. However, they advise against prescription topical treatments. Dr Wong agrees, stating that standard retinol products should be safe as long as they're used as intended.
But many health practitioners take a more cautious approach, advising against all topical retinoids. Laura Gerhady, a maternal fetal medicine specialist, highlights the lack of research on topical retinoids during pregnancy. "Most people using topical retinoids are doing so for non-vital conditions like acne," she explains.
The labelling of cosmetic skincare products containing retinoids is also a concern. There are no mandatory standards for retinal and retinol products, and only adapalene-containing products require labelling. Dr Gerhardy points out the lack of clear guidelines and information.
"For topical retinoids, we don't have great data. If you use it, it's probably fine, but communicating that on packaging is tricky," she says. "With oral retinoids, it's straightforward—they're harmful. But topical retinoids are more challenging due to the lack of data."
Precautionary Advice
Given the limited research, health practitioners' guidance is often interchangeable. Deshan Sebaratnam, a dermatologist, advises his pregnant patients to avoid all retinoids, including retinol, as a precaution. "Much like alcohol, it's safest to avoid retinol during pregnancy, but the absolute risk is low," he explains.
The American College of Obstetricians and Gynaecologists also advises against both prescription and OTC retinoid products, despite the low absorption rate.
Accidental Use: What Now?
Dr Wong reassures pregnant women who may have accidentally used topical retinoids. "It's generally not recommended, but it's not worth panicking if you've used it once or twice. The amount that enters your system topically is quite low, even from prescription creams."
A large Nordic study published last year found no evidence of increased risk of birth defects from topical retinoid exposure during pregnancy. However, the authors acknowledge the need for more research and the possibility of underestimating the risk.
Other Skincare Ingredients to Consider
Professor Sebaratnam recommends avoiding minoxidil (a hair growth formula) and hydroquinone (for dark spots). "Most other OTC beauty products are probably safe," he says, "but mums should consider whether they really need to use them."
Dr Wong also advises caution with online products that may be unregulated and high doses of salicylic acid, a cleanser and chemical exfoliator. Mothersafe NSW recommends confirming the safety of salicylic acid use with a healthcare provider, especially in specific situations where absorption may be higher.
The Bottom Line
For pregnant women, simplicity and well-regulated products are key. Always consult your healthcare practitioner for personalized advice. The retinoid debate continues, but with the right information, expectant mothers can make informed choices about their skincare routines.
