What is Retinal?
Retinal, also called retinaldehyde, is a vitamin A derivative. It sits one conversion step closer to retinoic acid than retinol, which is why formula strength and gradual introduction matter. Different percentages are not directly interchangeable across brands, so customers should follow each brand's step-up guidance rather than choosing the highest number immediately.
Who is this collection for?
Suitable for customers ready to add a targeted vitamin A step for visible-ageing, texture or blemish-mark concerns. New users and sensitive-feeling skin should begin with an entry-level formula and build frequency slowly.
How to use it
Use in the evening on cleansed, dry skin, following the specific product directions. Start with a low strength and a few nights per week, then increase only when skin remains comfortable. Follow with moisturiser and apply broad-spectrum SPF every morning.
