If you've been building a solid skincare routine, retinol is probably in it. It's one of the most evidence-backed ingredients for texture, collagen, and acne. But the moment trying to conceive (TTC) enters the picture, retinol becomes one of the first things that comes up. And the short answer is: yes, it's worth stopping before you start trying.
Here's the thinking behind that recommendation.
Why retinoids don't mix with TTC
Retinoids work by converting into retinoic acid in the skin. Retinoic acid is powerful precisely because it affects gene expression at a cellular level. That's also what makes it a concern when you're trying to conceive.
Retinoic acid is a known teratogen at high doses. A 1985 study (1) in the New England Journal of Medicine documented a characteristic pattern of birth defects in infants exposed to isotretinoin in the womb, including heart, brain, and craniofacial malformations, formally establishing retinoic acid as a confirmed human teratogen. Isotretinoin (Accutane / Roaccutane), the oral form prescribed for severe acne, is FDA Category X as a result: not to be used during pregnancy under any circumstances. Topical retinoids have much lower systemic absorption, but because they all convert to retinoic acid in the skin, the NHS, ACOG, and most dermatology guidelines worldwide recommend avoiding all retinoid forms during pregnancy and when TTC.
PregSafe's database reflects this: every retinoid form is rated avoid at the TTC stage.
Why TTC, not just pregnancy?
This is the part that catches people off guard. If topical absorption is low, why stop before a positive test?
The answer is timing. The most critical window for fetal development, when organs begin to form, is roughly weeks 3 to 8 after conception. Many women don't get a positive pregnancy test until week 4 or later. If you're using retinol right up until conception, the earliest and most sensitive weeks of a potential pregnancy could involve ongoing exposure before you know you're pregnant.
Removing retinoids before you start TTC means that uncertainty is already off the table.
What if you used retinol before you knew you were pregnant?
Try not to spiral. You can't change what happened before you knew, and worrying won't help. Mention it at your first antenatal appointment so your provider has the full picture. Knowing what's in your routine going forward is exactly what PregSafe is built for.
If you were taking oral isotretinoin (Accutane / Roaccutane) rather than a topical product, contact your doctor promptly rather than waiting for your first appointment.
It's not just retinol: the full list to check
This is where it gets easy to miss something. Retinol is just one of several vitamin A derivatives that appear on ingredient labels, often under names that don't make the connection obvious.
PregSafe flags all of the following as avoid when TTC:
- Retinol (also listed as vitamin A, all-trans-retinol, axerophthol)
- Retinal / retinaldehyde (one step closer to retinoic acid than retinol, more potent)
- Retinoic acid / tretinoin (the active form; also known as all-trans-retinoic acid)
- Retinyl palmitate, retinyl acetate, retinyl propionate, retinyl linoleate (vitamin A esters; milder because they need more conversion steps, but still end up as retinoic acid)
- Retinyl retinoate (a hybrid that breaks down into both retinol and retinoic acid in the skin)
- Hydroxypinacolone retinoate (HPR / granactive retinoid) (often marketed as a gentler next-generation retinoid, but it binds directly to retinoid receptors without needing to be converted, making it functionally similar to prescription tretinoin)
- Adapalene (Differin) (prescription-grade retinoid for acne)
- Tazarotene (prescription retinoid; a known teratogen)
- Isotretinoin (Accutane / Roaccutane) (oral; FDA Category X)
The one worth paying particular attention to is hydroxypinacolone retinoate. It's marketed heavily as being gentler and better tolerated than retinol, which may be true in terms of skin irritation. But gentler on skin is not the same as a different risk profile for TTC and pregnancy. If you see HPR, granactive retinoid, or retinyl retinoate on a label, treat it the same as retinol.
What to use instead
Several strong ingredients for texture, brightness, and acne aren't currently flagged in PregSafe's database:
- Azelaic acid: works on acne, redness, and post-breakout marks. Particularly useful if you're also thinking ahead to melasma, which pregnancy hormones can trigger.
- Niacinamide: regulates sebum, reduces inflammation, and helps with pore appearance.
- Vitamin C: supports brightness and helps with the pigmentation that can follow breakouts.
- Lactic acid: a gentler exfoliating option if you want to maintain some texture work without glycolic acid.

The bottom line
Stop retinoids before you start TTC, not when you get a positive test. Go through your full routine, not just your dedicated retinol serum: check moisturisers, eye creams, and SPFs, because retinyl palmitate in particular shows up in a wide range of products. And if you're not sure what's in something, that's exactly what PregSafe is for.
