Turmeric extracts and curcumin have been shown to be safe, even at high doses without significant side-effects. Previous clinical studies in other inflammatory skin diseases have shown that a dosage of curcumin at 6,000 mg daily was effective while lower doses were not. In a human phase I clinical trial examining the effects of high dose curcumin in preventing premalignant lesions, even curcumin doses as high as 8,000 mg/day resulted in no toxic effects after 3 months. This study will involve participant ingestion of 6,000 mg/day of turmeric or curcumin to assess how this affects their sebum production.
The investigators will also be collecting stool from the study subjects, and examining how the curcumin and turmeric may modulate their gut microbiome. The investigators will specifically be looking to see if curcumin or turmeric have any changes on the gut flora towards bacteria that produce more short chain fatty acids. Certain bacteria that make up the microbiome produce short chain fatty acids, such as butyrate and propionate, which have demonstrated anti-inflammatory properties. Thus, it would be interesting to see if turmeric or curcumin exert any of its anti-inflammatory effects via modulation of the microbiome.

- Sebum production [ Time Frame: 8 weeks ]Sebutapes will be used to measure sebum production at each visit. The sebutapes will then be collected and analyzed for fatty acids and lipid production.
- Change from Baseline in Sebum profile, such as inflammatory markers at 8 weeks [ Time Frame: 8 weeks ]
- Change in stool microbiome diversity (optional collections for subjects) from baseline at 8 weeks [ Time Frame: 8 weeks ]
