Brown sugar vs white sugar for acne
Brown sugar scores 87/100 (GOOD) and white sugar scores 95/100 (GLOW) on SpotBite's Skin Score. White sugar is the safer choice by 8 points, and the gap comes mostly from glycemic load.
Where the gap comes from
- Glycemic: Brown sugar has glycemic load 7.5 (11.7 g carbs), White sugar has 2.6 (4 g carbs). Faster sugar means more insulin, which can raise skin oil.
Evidence: Smith 2007 RCT (n=43): a low-glycemic-load diet for 12 weeks lowered acne lesion count by 23.5 on average, versus 12 on the control diet (study). All 13 sources.

Verdict
If you are acne-prone, white sugar is the better pick of the two.
Not medical advice. Both scores are for the food on its own. What you eat with it changes the result, and breakouts usually show up 3 to 7 days after a meal. Diet is one factor among many.
