Retin-A is a topical solution available by prescription that treats acne. PubMed Health, a website of the National Institutes of Health, notes that Retin-A is not a cure for acne. It simply manages it. Users of the product should limit their exposure to sunlight and artificial UV rays, according to Drugs.com. Further, users should not use the product if their skin is sunburned, chapped, or irritated.
Skin Coloring
The use of Retin-A may cause your skin to either lighten or darken in the area you apply the product, according to MedlinePlus, a website of the National Institutes of Health. It is fairly common for the product to lighten the skin, but rare for Retin-A to darken the skin, according to MayoClinic.com.
Burning
A side effect associated with the use of Retin-A is a burning, tingling or stinging sensation in the area where the user applies the product, according to MayoClinic.com. This symptom typically arises shortly after the user applies the product in the affected area and lasts briefly. The user of Retin-A may also experience a feeling of warmth after using the product.
Skin Dryness
A common side effect linked to the use of Retin-A is skin dryness, according to MayoClinic.com. Dryness may lead to peeling or chapping of the skin in the treated area.
Acne Increase
PubMed Health cautions that the user's acne typically worsens during the initial days of treatment, and the user may observe an increased number of acne sores. After seven to 10 days, the user will notice a decrease in the number of acne sores, according to PubMed Health.
