Oat milk vs soy milk for acne
Oat milk scores 84/100 (GOOD) and soy milk scores 96/100 (GLOW) on SpotBite's Skin Score. Soy milk is the safer choice by 12 points, and the gap comes mostly from glycemic load.
Where the gap comes from
- Glycemic: Oat milk has glycemic load 11 (16 g carbs), Soy milk has 3.1 (9 g carbs). Faster sugar means more insulin, which can raise skin oil.
- Inflammatory fats: Oat milk has 0.5 g saturated fat and 0.3 g omega-6, Soy milk has 0.5 g and 2.1 g.
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, soy milk 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.
