What retinal does for your skin

Retinal · Retinaldehyde · Vitamin A aldehyde

TextureEvennessClarity

Retinal (retinaldehyde) and retinol are both vitamin A actives and they are used the same way: night only, two evenings a week to start, moisturiser alongside, SPF the next morning. The practical difference is pace and price. Retinal tends to feel brisker and people often notice the look of a difference from it sooner, while retinol is the slower, cheaper and more widely stocked option.

Retinal (retinaldehyde) is retinol's quicker sibling. It tends to move a little faster, and it usually costs more. In cosmetic terms it smooths and refines. Same night-active rules apply, it just tends to move quicker.

What Retinal is

Retinal is a vitamin A active that tends to move a little quicker than retinol. It's less common on drugstore shelves, so you'll usually find it in more specialist brands.

What is Retinal good for?

uneven or rough-looking texture
the look of fine lines
a generally uneven-looking tone
retinol users who want a faster-moving option

How do you use Retinal?
