Neutrogena Retinol Boost Anti-Aging Serum delivers concentrated retinol in a fast-absorbing formula designed to visibly reduce signs of ageing. This powerful serum works beneath the skin's surface to accelerate cellular turnover, smooth fine lines and wrinkles, improve skin texture, and promote a firmer, more youthful appearance. The lightweight consistency allows for deep penetration without heaviness, making it suitable for layering under moisturisers and eye creams in your evening routine.

For best results, start by applying 2-3 times per week to allow skin to build tolerance, gradually increasing to nightly use as tolerated. A small amount covers the entire face and neck, making the 30ml bottle economical despite its potency. Those new to retinol may experience mild dryness or sensitivity initially — this is normal and typically subsides as skin adjusts. Pair with a broad-spectrum SPF during the day, as retinol increases sun sensitivity, and enjoy progressively smoother, more refined skin with continued use.
