Topical retinoids are vitamin A derivatives commonly used in skincare to treat various skin conditions, including acne and wrinkles. They work by promoting cell turnover, helping to unclog pores and improve skin texture. These medications are available in different forms, such as creams, gels, and lotions, and can be prescribed or purchased over-the-counter. When using topical retinoids, it’s important to start slowly to minimize potential side effects like irritation or dryness. Users should apply them at night and use sunscreen during the day, as retinoids can increase skin sensitivity to sunlight. Regular use can lead to clearer, smoother skin over time.
