Breakout or purging?

I’ve been using this spot serum along with the other products available in the Blemish Clear range. I’ve now been using these products for 2 weeks and I’m unsure as to whether my skin is purging from the tea tree oil, or whether my skin has a sensitivity to the ingredients. My acne appears to be worse than it was, but the breakouts are still localized around my jawline. NOW solutions, any advice?

As for other things to note with the product, I absolutely love the refreshing citrus/tea tree scent and found you only needed a very small amount of the product. I also love that this entire range is cruelty free and vegan. I’m not a huge fan of the packaging and appearance of the product, but the pump dispensers do work well!
