Topical retinol, a vitamin A derivative within the retinoid family, is suggested by some studies to improve the appearance of fine lines and other signs of skin ageing. Retinoids are known for accelerating cell turnover and stimulating collagen production.
Dr Ahmed El Muntasar, a GP and aesthetics doctor, states that early improvements in skin texture and brightness can be expected within four to six weeks of consistent use. More significant results for pigmentation, acne, or fine lines may appear closer to eight to 12 weeks.
Among the products reviewed, Naturium retinaldehyde cream serum was highlighted as a budget-friendly option, available in 0.05% and 0.10% retinal strengths in the UK. Murad Resurgence Retinal ReSculpt overnight cream was noted for targeting wrinkles, combining encapsulated retinal with a NAD+ Lift Complex. For beginners, The Inkey List Starter retinol serum was recommended as a gentle formula.
Users of retinoids are advised that side effects such as redness and irritation are common, and it can take time to develop a tolerance. Consistent use of a broad-spectrum face SPF is also recommended, as retinoids can increase skin sensitivity to sunlight.
