One of the ingredients I trust most.

When your goal is softening fine lines and keeping skin firm, Retinal delivers, and the research properly backs it up. Skip it while you are pregnant or breastfeeding, and the rest of the time bring it in slowly.

Retinal, answered

Is Retinal safe during pregnancy?

No. Retinal is best avoided during pregnancy and breastfeeding. If you are pregnant or trying, leave this one out and ask your doctor about a safe alternative.

Who should avoid Retinal?

Approach Retinal with care if any of these apply to you: pregnancy, breastfeeding, very sensitive, and compromised barrier. Its irritation risk is moderate, so introduce it slowly and patch test first.

What concentration of Retinal actually works?

Research tends to show Retinal starts pulling its weight above 0.05%. If a brand prints the percentage, that is the number to look for.

During pregnancy

Leave Retinal out while you are pregnant or breastfeeding. It sits on the list of ingredients usually held back during this time.

When in doubt, check with your doctor or midwife. They outrank any website, including this one.
