Retinol and pregnancy — what to stop, what to use instead.

Retinol sits at an unusual position in skincare: it has more clinical evidence behind it than almost any other consumer ingredient, and a clearer contraindication during pregnancy than almost any other topical. The two facts coexist, and both are important to understand.

Why retinol is contraindicated in pregnancy

Retinol is a form of vitamin A. At therapeutic levels, vitamin A and its derivatives are teratogens — they interfere with normal fetal development, specifically with the structures that form from neural crest cells: the heart, brain, and craniofacial structures.

The evidence comes primarily from prescription-strength oral retinoids (isotretinoin, acitretin), which carry the most clearly established teratogenic risk. Topical retinol and retinoids absorb into the bloodstream at low levels, and while the systemic exposure from a consumer-strength topical is far lower than from oral retinoids, no safe threshold has been established for topical use during pregnancy.

This absence of an established safe threshold — not evidence that topical retinol harms a developing fetus at typical use levels — is the reason for the conservative recommendation. The risk-benefit calculation is straightforward: there is no meaningful skin benefit that justifies any uncharacterised developmental risk. Stop retinol when trying to conceive and throughout pregnancy.

Prescription retinoids

The guidance for prescription-strength tretinoin and adapalene is the same: discontinue during pregnancy. These compounds have higher systemic bioavailability than over-the-counter retinol and carry a more established theoretical risk. If a prescription retinoid was being used for acne, consult a dermatologist or GP for alternatives.

During breastfeeding

The evidence here is even less complete. Conservative guidance advises avoiding retinol and retinoids during breastfeeding as well, on the basis that systemic absorption — even at the low levels typical of topical application — carries theoretical risk via breast milk. Most dermatologists recommend waiting until after breastfeeding is complete before reintroducing.

What works safely during pregnancy

The good news is that the most effective ingredients for the most common skin concerns during pregnancy have a strong safety record.

Niacinamide is the most useful safe active for pregnancy skincare. It reduces hyperpigmentation — including the melasma that pregnancy hormones often trigger — supports ceramide production, regulates sebum, and reduces redness. At 4–5%, it addresses more concerns than any other pregnancy-safe active. There is no evidence of risk at topical use levels.

Azelaic acid is a naturally occurring dicarboxylic acid found in grains. It has been used topically in pregnancy for decades and is considered safe by most dermatology authorities. It addresses hyperpigmentation, post-inflammatory marks, and mild acne. Available over the counter at 10% and by prescription at 15–20%.

Vitamin C (L-ascorbic acid) is safe throughout pregnancy and is the appropriate partner for SPF in a morning anti-pigmentation routine. At 10–15%, it inhibits melanin synthesis and provides additional UV-filter support when paired with sunscreen.

Hyaluronic acid, squalane, ceramides. All barrier-supporting hydrators with no evidence of risk. These remain the right moisturising choices throughout pregnancy and breastfeeding.

SPF. Pregnancy hormones increase photosensitivity and the risk of melasma. Daily broad-spectrum SPF 30 or higher — particularly mineral filters (zinc oxide, titanium dioxide) which sit on the surface and are not absorbed — is the single most important protective step during pregnancy.

What else to reconsider

Alongside retinol, a few other commonly used actives warrant review during pregnancy:

Salicylic acid (BHA) at high concentrations or prolonged use is typically advised against in pregnancy, though most guidelines consider brief, low-concentration use (≤2%) on limited skin areas to be low risk. Clarify with a healthcare provider.

Chemical sunscreen filters — specifically oxybenzone — are sometimes flagged on the basis of endocrine-disrupting potential, though evidence at typical topical exposure is not conclusive. Mineral filters are the straightforward choice during pregnancy if any uncertainty exists.

Essential oils and high-fragrance products are worth reducing simply because sensitisation risk increases during pregnancy, not because of specific teratogenic concern.

Restarting retinol after pregnancy

Retinol can typically be reintroduced after breastfeeding is complete. Because the skin's tolerance resets to some degree during the months of absence, start again at the lowest available concentration once a week — the same protocol as an initial introduction — rather than resuming at the pre-pregnancy frequency and concentration.

The Lux & Glo position

The ritual niacinamide serum and squalane moisturiser are both safe throughout pregnancy and breastfeeding. The active in the serum — niacinamide at 5% — addresses the concerns most likely to be relevant during pregnancy: barrier support, sebum regulation, and hyperpigmentation.

Retinol can wait. The barrier work that makes retinol effective on return can be done in its absence.
