[Routine Help] Still purging from BHA - how soon is too soon to introduce an AHA?

Beauty Tips For Body Care
I've been using Paula's Choice 2% BHA Lotion twice a day (morning and night) for 10 days now. I had never used any kind of chemical exfoliant before, and a few days in I started purging. I'm still experiencing this initial purge but have already seen a noticeable improvement in the texture and radiance of the parts of my skin that don't have a small whitehead/cyst on them, so I'd say my skin is reacting well to the BHA.I have a lot of PIH from old breakouts, and my skin scars easily so I'm worried this purge might also lead to more marks. It seems like a lot of people on this sub have gotten better results with their PIH when combining a BHA and an AHA, so I was hoping to incorporate an AHA into my routine at some point. I'm wondering if now would be too soon, since I've only just started the BHA 10 days ago and am still purging from it?Paula's Choice AHA is a little pricey for me right now since I've just shelled out for the BHA and am on a budget, so I was looking into maybe trying the Nip + Fab Glycolic Fix Extreme Night Pads. They contain 5% glycolic acid and an undisclosed percent of salicylic acid, so I was thinking of continuing to use the PC BHA mornings and then one of these pads at night. Would now be an okay time to start using these, or should I wait a little longer for this BHA purge to pass first? Thanks!
