Once you're actively trying to conceive, the safest approach to melasma and open-pore treatments is to plan around the possibility that you could already be pregnant before you'd know it. A few common actives are best paused while trying, while several effective, safer alternatives can continue without that concern.

Why "trying to conceive" changes the skincare conversation

Early pregnancy is the window where some ingredients carry the most theoretical risk to a developing baby, and it's also the window you can't test your way out of early enough to react in time — a missed period and a positive test typically come weeks after conception has already happened. That's why several ingredients that are perfectly reasonable to use while not trying are usually paused once you start actively trying, rather than waited out until a positive test appears.

What's usually paused while trying to conceive

  • Retinoids and retinol (prescription tretinoin as well as over-the-counter retinol) are generally stopped before actively trying, since retinoids are linked to birth defects when used in pregnancy and the safest approach is to not be using them at all once conception could happen at any time.
  • Hydroquinone, a common melasma-lightening ingredient, has limited pregnancy safety data and is generally avoided once trying or pregnant, as a precaution.
  • Oral medicines sometimes used for stubborn melasma or acne (isotretinoin, and in some cases oral tranexamic acid) are stopped well before conception is attempted, often with a specific waiting period your prescriber will specify.
  • Higher-strength chemical peels (stronger glycolic, salicylic or TCA concentrations) and certain laser treatments for melasma or pore appearance are usually deferred — discuss timing with both your dermatologist and your gynaecologist rather than booking one while actively trying.

What's generally considered safer to continue

  • Daily broad-spectrum sunscreen is, if anything, more important while trying and during pregnancy, since pregnancy-related hormonal changes can make melasma worse with sun exposure — this is the single most impactful thing you can keep doing.
  • Azelaic acid is commonly considered one of the more pregnancy-compatible actives for both melasma and acne-related concerns, and is often suggested as a substitute for the ingredients above — confirm with your dermatologist for your specific skin.
  • Vitamin C serums are generally considered safe and can help with pigmentation and overall skin tone.
  • Niacinamide, often used for pore appearance and oil control, is widely considered safe and is a reasonable substitute for more aggressive pore-refining actives.
  • Gentle exfoliation and a simple, consistent routine — cleanser, a safer active, moisturiser, sunscreen — does more for pore appearance over time than any single intensive treatment, and carries no pregnancy-related concerns.

Open pores specifically

Pore size is largely determined by genetics, skin oil production, and skin elasticity — it isn't something any treatment permanently "closes," pregnant or not. While trying to conceive, the realistic approach is keeping pores clear (gentle cleansing, niacinamide, non-comedogenic products) and managing their appearance, rather than pursuing more intensive resurfacing treatments that are better timed for before you start trying or after you've finished breastfeeding.

The simplest safe routine while trying to conceive is sunscreen every day, plus gentle, well-tolerated actives like azelaic acid, vitamin C or niacinamide — and holding off on retinoids, hydroquinone and intensive procedures until you're done trying or have finished breastfeeding.

Frequently asked

I used a retinol cream a few days before finding out I was trying — should I panic?

A brief, early exposure before you even started actively trying is a very different scenario from ongoing use once you know you're trying to conceive. If you're concerned about anything you were using recently, mention it to your doctor at your preconception visit rather than worrying alone — but the right next step now is simply to stop and switch to a pregnancy-compatible routine going forward.

Can I resume my usual retinoid or hydroquinone routine as soon as I have a positive pregnancy test?

No — the point of pausing while trying is specifically to avoid a gap between conception and knowing about it. Continue the pregnancy-safer routine through pregnancy and, for several of these ingredients, through breastfeeding as well; ask your dermatologist when it's appropriate to resume afterward.

Does melasma usually get worse once I am pregnant?

Melasma is strongly linked to hormonal changes and sun exposure, and pregnancy hormones can make it more pronounced for some women — which is exactly why consistent sunscreen use matters even more during this time, regardless of which other treatments you're using.

Should I see a dermatologist, my gynaecologist, or both about this?

Both, ideally. Your gynaecologist can confirm what's appropriate for your overall preconception and pregnancy plan, and a dermatologist can tailor the actual product and treatment choices to your specific skin.
