Retinoids are powerful treatment products derived from vitamin A that are highly effective in improving various skin concerns, including fine lines, wrinkles, acne, and hyperpigmentation. Available in both prescription-strength formulations (such as tretinoin and adapalene) and over-the-counter options (such as retinol), retinoids work by increasing cell turnover, stimulating collagen production, and promoting skin renewal. With consistent use, retinoids can help achieve smoother, firmer, and more youthful-looking skin, making them a cornerstone of many skincare routines.
