Can I alternate between two kinds of retinols?

Thank you for your question. It's great that you're taking an active role in your skin care and using prescribed retinols to improve your skin's health.
Both of the retinols you mentioned contain additional active ingredients. The first one contains azelaic acid and clindamycin, while the second contains hydroquinone, kojic acid, and hydrocortisone. These additional ingredients have their own unique properties and benefits for the skin.
However, it is important to use caution when combining multiple active ingredients in your skincare routine. Some ingredients may interact with each other and cause irritation or other unwanted side effects.
In general, it is best to use only one retinol product at a time in your skincare routine, as retinol can be quite potent and may cause irritation if overused. It is also important to avoid using multiple products that contain hydrocortisone, as overuse of this ingredient can lead to skin thinning and other side effects.
As for alternating between the two retinols you mentioned, it is best to consult with your dermatologist to determine the best course of action for your specific skin type and condition. Your dermatologist can evaluate your skin and provide personalized recommendations for how to incorporate these products into your skincare routine without causing any adverse effects.
In conclusion, while both of the retinols you mentioned contain beneficial ingredients for the skin, it is important to use caution when combining multiple active ingredients in your skincare routine. It is best to consult with your dermatologist to determine the best course of action for your specific skin type and condition.
