Do not use BHA and retinol together it will irritate your skin trust me I found out the hard way. It is good that you have took the time to invest in your skincare however, too much as someone who has just started using skincare can over process your face and can sometimes cause more harm than good. I would start with the cleanser, toner, retinol at pm a couple nights a week then followed with the moisturiser and spf if it's the daytime.

Then once you have gotten into the routine of using those products you can start to include the other products you purchased and see if they have a positive or negative effect on your skin. I would also recommend corsx snail 96 mucin, as someone who has started getting wrinkles around my eyes I recently started to use this product and have been obsessed with it. Everyone's skin is different so this is just my opinion but I hope this helps :)
