Peptides vs Retinol: Dermatologists Compare for Firmer Skin
Dr. Derrick Phillips and Dr. Ellie Rashid, both consultant dermatologists, evaluate the effectiveness of peptides versus retinol in enhancing skin firmness. While peptides promote collagen synthesis and moisture, retinol, a derivative of vitamin A, is known for boosting cell turnover and collagen production, showing stronger evidence in reducing fine lines. Although retinol may lead to dryness and peeling, peptides are milder. Users can expect results from retinol in four to six weeks, with peptide hydration benefits appearing within weeks and firmness improvements taking eight to twelve weeks. Retinol is more suitable for individuals in their twenties dealing with acne or fine lines, while peptides are better for those showing early signs of aging. They can be combined. Recommended products are Celimax The Vita A Retinal Shot ($20) and SkinCeuticals P-Tiox Serum ($150).
