Pregnancy can be an exciting journey, often bringing a new sense of confidence and well-being. However, it can also come with challenges, like increased skin sensitivity, acne, and hyperpigmentation. While many skincare products help address these concerns, certain ingredients should be avoided during pregnancy to safeguard both maternal and fetal health.
“It’s challenging to determine exactly how much of a topical ingredient gets absorbed into the bloodstream,” says Dr. Roni Munk, cosmetic dermatologist at Dermapure. “The area of application and quantity used matter—thinner skin areas like the eyelids absorb more than thicker areas, such as the back. That said, absorption levels may range from 2 to 5%.”
Health Canada maintains a “hotlist” of restricted and prohibited cosmetic ingredients, though it doesn’t specify which are hazardous for pregnant individuals. Discuss your beauty routine with your doctor and consult them before introducing new products, even if they are naturally derived.
How Skin Changes During Pregnancy
Pregnancy brings profound hormonal shifts that impact not only the body but also the skin. For many, this period brings a radiant glow, thanks to increased blood flow and better hydration. However, pregnancy can also introduce skin challenges. For example, hormones like estrogen and progesterone stimulate melanin production, leading to dark patches known as melasma or the “pregnancy mask.”
Additionally, the sebaceous glands may become more active, which can trigger acne breakouts, especially during the first trimester. Increased skin sensitivity is also common, making it more reactive to skincare products or even sunlight. These changes highlight the importance of adapting one’s skincare routine to accommodate these sensitivities and to avoid certain potentially harsh ingredients, protecting both maternal and fetal health.
“Pregnancy can increase sensitivity to various ingredients,” explains Laura Townsend, Canadian marketing director of The Detox Market. “So it’s wise to be cautious, even with natural products.”
7 skincare ingredients to be mindful of during pregnancy
1. Retinol
Also known as Retin-A or retinyl palmitate, retinol is a derivative of vitamin A. While vitamin A is essential for fetal growth, high doses have been linked to malformations affecting the head, heart, and spine.
“Even though skin absorption of retinol is minimal, the risk remains,” advises Dr. Munk. “For acne, glycolic or oleic acid are safer alternatives, and for anti-aging, sunscreen is an effective, risk-free choice.”
2. Chemical Sunscreen
Everyone benefits from sun protection, but pregnant patients should choose physical sunscreens over chemical ones. Chemical filters like oxybenzone and avobenzone may act as hormone disruptors and could potentially affect fetal health. Studies link them to risks like childhood obesity and ADHD. Opt for mineral-based sunscreens for safe and effective protection.
3. Benzoyl Peroxide and Salicylic Acid
Hormonal fluctuations during pregnancy can lead to acne. While medications like Accutane are off-limits, benzoyl peroxide and salicylic acid have mixed opinions. “Taken orally in high amounts, these ingredients have known risks,” explains Dr. Munk. “But topical use can be safe if applied in limited quantities to small areas to reduce absorption.”
4. Hydroquinone
Hydroquinone is commonly used to treat melasma, or “mask of pregnancy.” With an absorption rate between 35 and 45 percent, experts recommend avoiding it.
“Potent anti-pigment agents like hydroquinone are not advised during pregnancy,” says Dr. Munk. “Glycolic or linoleic acids, along with sunscreen, are safer alternatives.”
5. Parabens
Used as preservatives in many cosmetics, parabens are hormone disruptors that are readily absorbed by the skin. Studies have linked prenatal exposure to types of parabens like BPA with issues such as low birth weight and behavioral problems.
6. Aluminum Chloride
Aluminum chloride, often found in antiperspirants, is generally safe in low doses, but higher concentrations—like those found in hyperhidrosis treatments—may pose risks. Standard antiperspirants contain 3-6% aluminum chloride, while prescription-strength options contain up to 30%.
7. Essential Oils
Not all essential oils are pregnancy-safe. While some offer natural benefits, oils like jasmine and clary sage may trigger contractions, and sage and rosemary oils may contribute to bleeding and increased blood pressure. Townsend advises waiting until the third trimester and consulting with a physician before using essential oils.
“Pure, undiluted essential oils carry more risk,” Townsend cautions. “Diluted oils are typically safe, but research and medical consultation are key.”
Prioritizing Safe Skincare Choices
During pregnancy, increased skin sensitivity underscores the importance of consulting with your physician before introducing new skincare products. Everyone’s skin reacts differently, so prioritize gentle, pregnancy-safe options to ensure both a comfortable skincare experience and added peace of mind for you and your baby.
