Based on your question looking for a serum, I'd recommend the The Body Shop Tea Tree Daily Solution 50ML. This serum contains tea tree oil, which is ideal for blemish-prone skin as it has antibacterial properties. The serum helps clear pores and maintain clear skin. It's currently available for R325 from PriceCheck. Let me know if you need any other information on this serum or would like me to search for alternative options. As an AI assistant, I don't have access to the full product catalogs, but I'm happy to try my best to find what you need.
