Retinol, a popular ingredient in skincare, is well-regarded for its anti-aging properties. Its benefits include reducing fine lines and wrinkles, addressing pigmentation and sun damage, clearing pores, and improving overall skin texture and brightness. According to Kamisha Darroux, scientific adviser at Which?, retinol helps exfoliate the skin and boost collagen production, making it effective for both acne treatment and aging signs.

Dermatologist Dr. Anjali Mahto notes that retinol is a mild form of vitamin A, suitable for those new to this ingredient as it generally has fewer side effects compared to stronger retinoids. A 2024 analysis of six controlled studies involving participants with mild to moderate sun damage has confirmed that 0.1% retinol shows positive results in improving signs of photoaging, with minimal cases of skin irritation reported.
Experts recommend introducing retinol into your skincare routine around your late twenties when collagen production begins to decline. However, using it at a younger age is discouraged, especially for children and teenagers, as their skin is still developing.
For those new to retinol, starting with a low concentration (less than 0.5%) combined with soothing ingredients like niacinamide is advisable. Users should apply retinol once or twice a week at the start, gradually increasing frequency as the skin builds tolerance. Some initial skin irritation or a breakout can be normal, but if excessive discomfort occurs, users should pause application.
The safety of using retinol is also influenced by its combination with other skincare products. Avoid using it alongside vitamin C, certain exfoliants like AHAs and BHAs, and benzoyl peroxide, as these may irritate the skin or reduce retinol's efficacy. Instead, pairing retinol with hydrating ingredients like hyaluronic acid is recommended.
Furthermore, retinol can increase sun sensitivity, making sunscreen application essential during the day after using retinol at night. Pregnant or breastfeeding individuals are advised to avoid retinol due to risks associated with excessive vitamin A.
In recent years, alternatives like bakuchiol have emerged, offering similar benefits to retinol and being gentler on the skin. Research has shown bakuchiol's effectiveness in improving aging signs, making it a good option for sensitive skin.
Consultations with dermatology professionals are encouraged for those with existing skin conditions or sensitivities before starting retinol.
Several products are available for beginners that feature lower percentages of retinol. However, UK and EU regulations now limit facial skincare products to a maximum of 0.3% pure retinol, prompting some brands to reformulate their products. While this does not indicate that higher concentrations are unsafe, it aims to minimize consumers' overall exposure to vitamin A. Stronger prescription retinoids remain unaffected by these regulations.
