Welcome to the INKEY Blog. Where we spread and share our skincare knowledge with you!

Retinol is one of the most scientifically proven ingredients in skincare, delivering powerful benefits for ageing, texture, acne, and overall skin health—but its effectiveness depends heavily on how it’s used. Because retinol works through a precise conversion process within the skin, combining it with incompatible ingredients or incorrect layering can reduce results and trigger irritation. Understanding the science behind retinol interactions allows you to avoid common pitfalls, pair it with supportive ingredients, and build routines that maximise benefits while protecting the skin barrier. With the right knowledge, retinol becomes not an intimidating active, but a transformative tool for long-term skin health.

Retinol vs bakuchiol is one of the biggest debates in anti-ageing skincare right now, with experts split between proven performance and gentle, natural alternatives. This guide cuts through the noise with clear, science-backed insights into how each ingredient works and how they compare. The truth is, there’s no single winner—retinol delivers powerful, research-backed results, while bakuchiol offers a gentler option for sensitive skin. The key is choosing what best suits your skin, lifestyle, and tolerance.
