Can I use Betaine Salicylate and Capryloyl Salicylic Acid together?

Piel's routine check says: Caution

Two exfoliating acids in one routine is more exfoliation than most skin needs. Keep one, or alternate nights. This applies when applied at the same time.

This is a dose question rather than an interaction. Two exfoliating acids do not react with each other; they simply exfoliate twice, and skin has no way of telling that the second one came from a different bottle. A cleanser, a toner and a leave-on serum can each be carrying one, which is how a routine ends up at twice the exfoliation nobody planned.

Piel's exfoliating-acid family spans both the AHAs and the salicylic-acid side, so a glycolic toner and a salicylic cleanser count as two.

Keeping one, or alternating nights, gives the same result without the flaking and tightness that over-exfoliation brings. If skin already feels rough or tight, or stings when moisturiser goes on, pause both and let it settle first.
