Retin-A.

Retin-A (tretinoin topical) can be prescribed for people diagnosed with acne and looking to get this condition under control. Do not apply too much of Retin-A as this is unlikely to increase the efficiency of your treatment. Make sure you always apply as much as recommended by your health care provider or as directed on the label. Your doctor will need to know if you are using any other medications, especially those that have been reported to make your skin very sensitive to the effects of sunlight. You will need to tell your doctor if you are using or have recently used any of the following medications: promethazine, diuretics, sulfa drugs, chlorpromazine, prochlorperazine, tetracycline, or any antibiotics. Since this drug can make your skin sensitive the sunlight and artificial light, make sure you apply sunscreen with SPF 15 and wear protective clothing that would cover your skin when you go outside and have to stay there for quite some time. Sometimes Retin-A causes side effects in people using it. You may get stinging, tingling, warmth, dryness, burning, peeling, itching, redness, swelling, and irritation, especially at the beginning of the treatment. However, those symptoms are unlikely to last for too long and tend to go away as you continue the applications.
