From my exfoliate? Idk if this is possible or if it’s what’s actually happening?

I’ve been using St. Ives green tea scrub go a maybe like 5 months now and at first it worked really good, but I’ve been noticing a lot of bumps on my chin/jaw and idk if that’s from the scrub or not. If it not from the scrub then id say it works great but idk. Have any of u guys experienced this or anything?

I make sure to wash the scrub all off and everything so idk what it could be. Maybe it’s cuz my skin is sensitive? Ah help please!
