Retinol is a Vitamin A derivative widely used for different skin issues like acne, acne marks, fine wrinkles and antiaging. It acts by increasing cell turnover (pushing new cells from the bottom layer of skin to the top), reducing oil production and improving collagen support to skin to make it firmer. Prolonged use can make the skin look brighter, younger, firmer and remove spots as well.

However, using retinol has a number of disadvantages:

·        Starting retinol on active acne can cause Purging. This is a severe acne breakout that lasts for one to two months and may cause marks or scars. Continued use settles the purging after two months.

·        Severe pus filled and nodular acne may not respond to retinol which is weaker than other topical retinoid products.

·        Retinol often causes dryness and irritation and hence it is advised to start with a low dose and intermittent short-time application.

·        Retinol makes the skin thinner and more sensitive to sun damage. Hence it is to be used at night along with appropriate daytime sun protection.

·        Retinol should not be used in pregnancy as it can harm the baby.

Due to these side effects and potential problems, you should consult a dermatologist before using retinol for your acne. A good skin care regimen with mild facewash, appropriate sunscreen and moisturiser is essential before starting retinol, especially if your skin barrier is damaged. Doctors may also recommend starting alternate day application with short contact time for your skin to become used to retinol.
