Aw mama, I haven't personally tried Tiny Buds pero a few of us in our mum circle swear by it, usually takes around 1-2 weeks to see real improvement, kaya don't lose hope yet! Baby acne can be stubborn talaga, and sometimes it gets worse before it gets better dahil sa hormones pa lang niya, pero if it's not improving after 2-3 weeks or mumukhang infected na, better check with pedia to rule out anything else, sometimes what looks like acne ay might need different approach din. How old is your baby po?
