[Routine Help] Will I still see the same effects from a Vitamin C Serum if I only use it every other day, as opposed to every day? Also, is my rotation of exfoliants appropriate?

Beauty Tips For Body Care
I used OST C20 in the past, and applied it every night with great results but I've switched to the Active Formulas (or Skin Actives in the US) L-AA based serum that has quite a low ph (1.5). I've also added AHA to my routine very recently, and I've been using BHA for a while.When I used Vit C daily before it was amazing at helping to even my skintone but I don't want to end up putting my skin through more than it can handle. I feel like a safe rotation of exfoliants would be to use Vitamin C every other day, BHA on days that I don't use Vitamin C and then keep my AHA at around 2-3 times weekly use.I just wanted some outside input as to whether this seems like an appropriate approach to using exfoliating products.
