What it is

Retinal, short for retinaldehyde, belongs to the retinoid family alongside retinol. The skin converts retinol to retinal and then to retinoic acid; retinal starts one step further along, which is why it is used at much lower percentages than retinol.

It breaks down in light and air. Ours is held in a squalane base in an airless, opaque pump.

How we use it

In two strengths, 0.05% and 0.1%, in a base with 5% squalane to buffer the formula. Start with the lower one.

How to use

Evening only, on dry skin after cleansing. Begin with two nights a week and add a night every fortnight if your skin is comfortable. Follow with moisturiser.

Pairs well with

Squalane, ceramides and glycerin, which keep skin comfortable while it adjusts. Sunscreen every morning.

Cautions

Dryness and flaking are common in the first weeks. Do not use on the same evening as exfoliating acid. Retinoids are not recommended during pregnancy or while breastfeeding; ask your doctor. Use sunscreen daily.
