[Routine Help] Which comes first: retinol then hydroquinone or other way around?

Beauty Tips For Body Care
Hi there,I just ordered the CeraVe Resurfacing Retinol Serum (still waiting for it to ship) and I’m wondering where in my PM routine can I use it?Current PM Routine:CeraVe Foaming Facial CleanserPaula’s Choice 2% BHA Liquid Exfoliant (3x a week)Biossance Lactic Acid + Squalane Resurfacing Night Serum (3x a week, when I’m not using BHA)The Ordinary 10% Niacinamide + 1% Zinc (though I might cut this out cause I might have too much niacinamide?)Hydroquinone 6% (prescribed)CeraVe PM Facial MoisturizerI’ve heard of people using both hydroquinone and retinol (or tret) in the same routine, but I’m wondering which goes first? Hydroquinone then retinol? Or other way around?I’m also aware of not using actives when using retinol, so I’ll make sure to not use the BHA and lactic acid on the nights when I use retinol. This will also be the first time that I use retinol, so I am looking to start using it only 1-2x a week at first.Hoping to treat my PIH/PIE as well as enlarged pores and acne scars. :(
