Whitehead like pimples to top lip after waxing ?

[Lousylo66]

had my tache waxed probably 7-8 wks ago and developed a couple of largish pimples to top lip a day or so after.Have now noticed more smaller ones, in fact lots more all to top lip and even a few rogue ones on chin. Not first time I've had this area waxed but never reacted like this . Starting to look like elephant man. Gp prescribed antibiotics but tbh the spots don't look infected. Any ideas what they could be and more importantly how to get rid if them ? Thanks in advance
