Using tretinoin without a doctor’s prescription carries significant risks. You might experience dryness, redness, and peeling skin, often described as sunburning. This irritation can be severe, especially at the start. Some individuals develop a burning sensation or itching.
Increased Sun Sensitivity
Tretinoin dramatically increases your skin’s sensitivity to sunlight. Sunburns become far more likely, potentially leading to long-term skin damage and increased risk of skin cancer. Always use a broad-spectrum sunscreen with an SPF of 30 or higher, and limit sun exposure, especially during peak hours.
Other Potential Issues
Beyond sun sensitivity, unprescribed tretinoin use can result in persistent skin irritation, hyperpigmentation (dark spots), or hypopigmentation (loss of pigment). Rarely, more serious reactions such as allergic contact dermatitis may occur. Remember, these are potential side effects; they don’t necessarily affect everyone.
If you experience any unexpected or severe reactions, discontinue use immediately and consult a dermatologist. They can diagnose the issue and provide appropriate treatment.
