retin a and differin used together

Awhile back i was taking retin A in the morning and differin at night. My acne seemed like it got better that time. Now like 6 months later of not using anything my acne is really bad and I keep looking to see if retin a and differin can be used right together. But everywhere i look it says that they are used seperatly.
So please help me !
Thank you so much

Hi. You may need to continue with oral or topical medication for a long as you are prone to acne, if it returns after stopping treatment. It is better to use either Differin or Retin-A, not both together. They are both synthetic retinoids and using them together will increase the risk of side effects such as redness, peeling and irritation. As they are both very effective it is also simply unecessary to use both. If you feel that you warrant more than topical preparations, speak to your doctor about taking oral antibiotics in addition to using one of these topical retinoids.
