Frequently asked questions

Is retinal stronger than retinol?

Retinal (retinaldehyde) is one conversion step closer to the active form in skin, so it generally works faster than the same strength of retinol.

How often should I use a retinol serum?

Start two or three evenings a week and build up as your skin tolerates it. Always wear sunscreen during the day.

Can I use retinol while pregnant?

Retinoids are generally not recommended during pregnancy or breastfeeding — check with your GP or pharmacist.
