Overview:
Facts:
- Skin Renewal: Retinol speeds up cell turnover, helps clear clogged pores, and visibly reduces fine lines and dark spots.
- Start Slowly: Beginners should introduce retinol gradually (1–2 times a week at night with a low concentration) to build tolerance.
- Sun Sensitivity: Retinol increases UV sensitivity, making daily broad-spectrum, high-SPF sunscreen essential.
