In this detailed discussion, Dr. Zoe Draelos explains the science behind retinoids, a class of compounds renowned for their powerful anti-ageing properties.

Retinoids, including prescription forms and over-the-counter versions like retinol, work by activating specific receptors in the skin. This interaction stimulates collagen production, tightens the skin, and helps older skin behave more like younger skin. Dr. Draelos emphasises that while retinoids are highly effective, they can cause irritation, especially in the initial weeks of use, but careful formulation can minimise this effect.

She also highlights the transformation process of retinol into retinoic acid, its active form, and its critical role in improving skin texture and firmness. As one of the few ingredients with receptors in the skin, retinoids stand out as an essential component in anti-ageing skincare, offering scientifically backed benefits that enhance the appearance and health of the skin.
