Use retinol and self tan together?

[Glassesareneeded]

I'm hoping someone can advise me about how to use certain products, as I'm getting myself confused!

I'm trying to get a new routine together to improve my facial complexion after a year of neglect! Sorted out my various serums and creams, and ordered some new things.

I've ordered a new retinol, Medik 8 crystal retinal, but would also like to use face tanning drops for some colour. I'm looking at tan luxe but not bought those yet, thought I'd best sort out retinol first.

Can I use the drops in my night time moisturiser or oil after the retinol? Any body who has successfully used retinol and self tanner, I'd appreciate your comments. I'm just wondering if I should alternate the nights I use the products, or if they can be used on the same night?

I'm also wanting to restart using vitamin c but thought I'd start on one new product at a time. I do have an SPF to use daily so that's one thing I've cracked

Anyone who uses these products and can share their routine, I'd be greatful as I'm getting myself confused! Also, which tanning drops are good for pale skin?

Many thanks.

@Glassesareneeded. I really like balance me vitamin c. I try others but always come back to this. I also like their tanning glow drops, help perk up a winter pale face. I also use retinol.

Thanks for all the advice. I've placed an order for vitamin c serum instead of self tan so awaiting my goodies... And hoping for a naturally glowing complexion soon!!
