Retinaldehyde, commonly shortened to Retinal, is an advanced Vitamin A derivative that sits closer than Retinol to the skin’s natural chemical pathway to active vitamin A. As Retinal is only one conversion step away from active Vitamin A compared to two for Retinol, Retinal is known for its faster-acting performance.

Retinal helps visibly improve the appearance of fine lines, uneven skin tone, texture irregularities and other signs of skin ageing — while remaining suitable for a well-formulated, gentle skincare routine.

Dr Mayson’s three Retinal Serums are:

• Active-A Renewal Serum 0.25%
• Active-A Renewal Serum 0.5%
• Active-A Renewal Serum 1%
