Using tretinoin for wrinkles has become a widely recommended solution in dermatology for improving signs of aging. Tretinoin, a retinoid derived from vitamin A, works by increasing cell turnover and stimulating collagen production in the deeper layers of the skin. Over time, this process helps to smooth out fine lines, soften deeper wrinkles, and improve skin firmness and elasticity. In the early stages of treatment, it’s common to experience dryness, flaking, or slight irritation as the skin adjusts. These effects usually subside after a few weeks. For best results, tretinoin should be applied in a thin layer at night, followed by a moisturiser to reduce sensitivity. Sunscreen during the day is essential, as tretinoin can make the skin more prone to sun damage. Visible improvements typically begin after 8 to 12 weeks of consistent use, with more noticeable wrinkle reduction appearing after several months. Continued long-term use leads to smoother texture, more even tone, and a refreshed, youthful look. Whether you're targeting early fine lines or deeper wrinkles, tretinoin for wrinkles offers one of the most effective, research-backed options to support long-term skin rejuvenation. Patience and consistency are key to achieving lasting results.
