It's sure not something I'd like to use if I was going to the beach, or in the sun.
What should I avoid while using Retin-A?
Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Retin-A can make your skin more sensitive to sunlight and sunburn may result. Use a sunscreen (minimum SPF 15) and wear protective clothing if you must be out in the sun. Avoid getting Retin-A in your eyes, mouth, and nose, or on your lips. If it does get into any of these areas, wash with water. Do not use Retin-A on skin that is sunburned, windburned, dry, chapped, or irritated. Also avoid using this medicine in wounds or on areas of eczema. Wait until these conditions have healed before using Retin-A.
