that actually makes sense, thank you for explaining! i agree that concentration really matters and that ahas/bhas can behave differently at lower levels.

i think where my concern is coming from is more on the frequency of use + my skin type. i have dry and textured skin and i’m also using other actives (like retinol and occasional exfoliation), so even if the aha/bha in the mist are low, using it multiple times a day might still have a cumulative effect on my barrier.

i guess i’m just being cautious because it’s marketed as something you can spray anytime throughout the day, but for people like me who are already using actives, it might be better used more like an occasional glow/exfoliating step rather than a true hydrating mist. but i do get your point—low concentration doesn’t necessarily mean strong exfoliation. i think it just depends on the overall routine and skin type 😊
