Best for

Anyone new to retinoids. Anyone who has tried a retinol before and found it too irritating. A sensible starting point before moving to a higher strength.

How to use

Apply a small amount to dry skin at night, two or three nights a week to begin, building up as tolerated. Follow with a moisturiser. Daily sunscreen the next morning is not optional.

What to expect

Mild dryness or flaking in the first few weeks is normal. Texture improvements from around week six. Fine line and tone benefits build from twelve weeks onward with consistent use.

Evidence level

Well established

Retinaldehyde converts to retinoic acid in one metabolic step, the fewest of any non-prescription retinoid, giving it a strong and consistent evidence base for texture, fine lines and breakouts at a manageable strength.

This level reflects published research on the key ingredients or product class. It does not mean this exact formulation has been independently proven, and it is not a medical endorsement or a guarantee of results.
