When choosing skincare products aimed at reducing signs of aging, experts advise focusing on ingredients that have strong scientific support. Dr. Brandon Richland, a board-certified plastic surgeon, and Allyse Cirillo, founder and CEO of SAINT JŌ, highlight retinoids—such as retinol (available over the counter) or prescription tretinoin—as the most effective for improving skin texture and reducing visible aging. These ingredients work by boosting collagen production, a protein that helps keep skin firm and elastic. Vitamin C is recommended for morning use as an antioxidant, which helps protect the skin from damage caused by environmental factors like sun exposure and pollution. Niacinamide is also praised for strengthening the skin’s natural barrier and reducing redness or uneven skin tone. Peptides, which are small protein fragments, are often used in skincare to signal the skin to produce more collagen and are generally gentler than retinoids. Hydrating ingredients like hyaluronic acid and ceramides are important for maintaining the skin’s moisture barrier and overall health. Both Dr. Richland and Cirillo emphasize that using a broad-spectrum sunscreen with SPF daily is one of the most effective ways to protect skin from aging caused by sun exposure. They both agree that no other anti-aging ingredient can match the protective power of consistent SPF use. Dr. Richland cautions against products that contain topical collagen, noting that collagen molecules are too large to penetrate the skin and only offer temporary surface-level hydration. He also warns against overusing strong acids or retinoids without proper skin support, which can lead to irritation. Cirillo adds that some skincare products promising quick or dramatic results may actually harm the skin over time by causing dryness or inflammation. When starting an anti-aging skincare routine, Dr. Richland suggests beginning in the late twenties or early thirties with a basic regimen that includes an antioxidant and a daily SPF. Prevention, he says, is more cost-effective and easier than trying to reverse aging later. Recommended products include the Facethory glow-C daily moisturiser with SPF30, which combines antioxidant, moisturizing, and sun protection benefits. The Clarins double serum is noted for its ability to smooth the look of fine lines and pores, while the Estee Lauder Advanced Night Repair Synchronized Multi-Recovery Complex is praised for its hydrating formula and use of peptides to enhance skin firmness.
