Tretinoin and vitamin C together

[Aoki33]

So I have seen that using vitamin C and tretinoin is bad and to use moisturizers like the sandwich method but the problem is that I have a moisturizer which is of vitamin C and the sunscreen which I have is also vitamin C. Would it be okay to use the sunscreen in the morning and skip moisturizer at night cause of tretinoin

just buy a moisturizer without vitamin c

Vitamin C and tret have different pH levels and tret being sensitive to light and pH changes it gives less results and more irritation
