Pregnancy changes your skin in ways you might not expect — from the coveted "pregnancy glow" to unexpected breakouts, pigmentation, and sensitivity. With so many products on the market, it's natural to wonder what's safe to put on your skin while growing a baby.
The good news is that most everyday skincare products are perfectly safe during pregnancy. However, there are some specific active ingredients that should be avoided or used with caution.
Ingredients to Discuss with Your Healthcare Provider
Retinoids (Vitamin A Derivatives)
Why to avoid: high doses of vitamin A are linked to birth defects. While topical retinoids absorb less than oral forms, dermatologists and obstetricians recommend avoiding them entirely during pregnancy as a precaution.
Look for on labels: retinol, retinal, retinoic acid, tretinoin, adapalene, tazarotene, isotretinoin. Also listed as retinyl palmitate or retinyl acetate in some products.
Found in: anti-aging creams, acne treatments, some night serums, and prescription skin medications.
Salicylic Acid (High Concentrations)
Why to avoid: salicylic acid is related to aspirin (acetylsalicylic acid). In high concentrations, it may be absorbed through the skin in quantities that could affect the baby.
The nuance: low concentrations in face washes (under 2%) are generally considered safe by most dermatologists because the product is rinsed off quickly. However, leave-on treatments like toners, peels, and serums with higher concentrations should be avoided.
Found in: acne treatments, spot creams, chemical exfoliants, and some toners.
Hydroquinone
Why to avoid: this skin-lightening ingredient has a relatively high absorption rate through the skin (25-45%). While no studies have shown definitive harm, the significant absorption rate makes most healthcare providers advise against use during pregnancy.
Found in: skin-brightening products, treatments for melasma and dark spots.
Chemical Sunscreen Ingredients
Why to use caution: some chemical UV filters — including oxybenzone, avobenzone, and octinoxate — may be absorbed into the bloodstream. While research on pregnancy effects is limited, many experts recommend switching to mineral (physical) sunscreens as a precaution.
Safer alternative: mineral sunscreens containing zinc oxide or titanium dioxide sit on top of the skin and reflect UV rays rather than absorbing them.
Formaldehyde and Formaldehyde-Releasing Preservatives
Why to avoid: classified as a carcinogen. Some hair straightening treatments (keratin treatments) release formaldehyde when heated.
Look for on labels: formaldehyde, formalin, methylene glycol, DMDM hydantoin, quaternium-15.
Self-Tanners (DHA)
Why to use caution: the active ingredient dihydroxyacetone (DHA) has not been thoroughly studied in pregnancy. While it primarily reacts with the outer layer of dead skin cells, the potential for inhalation during spray tanning is an additional concern.
Safer alternative: embrace your natural skin tone, or use a gradual tanning moisturiser (which contains lower levels of DHA) rather than spray tans.
Ingredients That Are Safe During Pregnancy
You don't need to abandon your skincare routine entirely. These ingredients are widely considered safe:
Hyaluronic Acid
A naturally occurring substance in your body that provides intense hydration. Excellent for combating pregnancy-related dryness.
Vitamin C (Ascorbic Acid)
A powerful antioxidant that brightens skin and supports collagen production. A great alternative to retinol for anti-aging concerns.
Niacinamide (Vitamin B3)
Helps with acne, redness, and hyperpigmentation — all common pregnancy skin concerns. Widely considered safe throughout pregnancy.
Glycolic Acid (Low Concentrations)
An alpha hydroxy acid (AHA) that provides gentle chemical exfoliation. Generally considered safe in concentrations under 10% for home use, though chemical peels with higher concentrations should be avoided.
Azelaic Acid
One of the few prescription acne treatments considered safe during pregnancy. Effective for breakouts, rosacea, and hyperpigmentation.
Mineral Sunscreen
Zinc oxide and titanium dioxide are pregnancy-safe sun protection. SPF 30 or higher is recommended, as pregnancy hormones can increase sensitivity to UV radiation and worsen pigmentation (melasma or "pregnancy mask").
Shea Butter and Natural Oils
Cocoa butter, coconut oil, and rosehip oil are safe moisturisers that may help with comfort as skin stretches, though no product has been proven to prevent stretch marks.
Reading Product Labels
A practical approach to assessing your skincare during pregnancy:
- Check active ingredients first — these are listed on the packaging and are the components most likely to cause concern
- If in doubt, search the ingredient name with "pregnancy safety" — most major ingredients have been assessed
- Simplify your routine — pregnancy is a good time to pare back to the essentials: cleanser, moisturiser, and sunscreen
- Ask your GP, midwife, or dermatologist about any specific products you're unsure about
Common Pregnancy Skin Concerns
| Concern | Safe Treatment Options |
|---|---|
| Acne breakouts | Azelaic acid, niacinamide, gentle cleansers |
| Dry skin | Hyaluronic acid, ceramides, natural oils |
| Melasma (dark patches) | Vitamin C, mineral SPF 30+, niacinamide |
| Stretch marks | Moisturisers for comfort (prevention is largely genetic) |
| Sensitivity and redness | Fragrance-free products, ceramide creams |
The Bottom Line
Most skincare products are safe during pregnancy. The ingredients most commonly flagged by dermatologists include retinoids, high-concentration salicylic acid, hydroquinone, and certain chemical sunscreens. When in doubt, switch to simpler products and speak to your GP or dermatologist for personalised guidance.
Your skin will go through many changes during pregnancy — some welcome, some less so — but they're all temporary signs of the incredible work your body is doing.
