Tretinoin requires a prescription from a dermatologist, limiting accessibility. Retin-A is a brand name for tretinoin, also requiring a prescription. Over-the-counter retinoids, like retinol and retinaldehyde, offer lower concentrations of similar active ingredients.
Prescription Strength
Prescription tretinoin comes in higher concentrations, ranging from 0.025% to 1%. Higher concentrations treat more severe acne and wrinkles more effectively, but also cause more irritation.
Over-the-Counter Strength
Over-the-counter retinoids typically contain much lower concentrations of active ingredients (often below 0.1%). This significantly reduces the risk of irritation, making them suitable for sensitive skin. However, results may be slower and less dramatic compared to prescription strength.
The choice depends on your skin condition and tolerance. Discuss options with a dermatologist to find the best treatment plan for you. They can assess your skin and recommend the appropriate strength and formulation.
