My routine is as follows:

Morning Routine:

• Cleanser - La Roche-Posay Toleriane Hydrating Gentle Face Cleanser
• Vitamin C - Timeless Skin Care
• Azelaic acid - Paula's Choice 10% Azelaic Acid Booster
• Moisturizer - La Roche Posay Toleriane Face Moisturizer Sunscreen with Ceramide and Niacinamide

Night Routine:

• Cleanser - La Roche-Posay Toleriane Hydrating Gentle Face Cleanser
• Generic Tretinoin (0.05%)
• Moisturizer - CeraVe PM Facial Moisturizing Lotion

My question is, I want to start using an SA cleanser (probably LAP EFFACLAR), two times a week. I heard using SA cleanser in the morning is bad for you but I also heard using SA cleanser at night might reduce the effectiveness of the tret and it might be too harsh on my skin? I would appreciate any guidance. Thanks!
