Retinol

What it does

Retinol is converted to retinoic acid in the skin, where it binds to retinoid receptors to accelerate cell turnover and stimulate collagen synthesis. It works gradually and is gentler than prescription retinoids, making it suitable for over-the-counter use. Effects typically appear after 4–12 weeks of consistent application.

Benefits

• Helps minimize pore appearance and refine skin tone

• May help with acne and post-inflammatory hyperpigmentation
