Cake slice vs dark chocolate for acne
Cake slice scores 52/100 (WARN) and dark chocolate scores 89/100 (GOOD) on SpotBite's Skin Score. Dark chocolate is the safer choice by 37 points, and the gap comes mostly from glycemic load.
Where the gap comes from
- Glycemic: Cake slice has glycemic load 27.3 (42 g carbs), Dark chocolate has 3.2 (14 g carbs). Faster sugar means more insulin, which can raise skin oil.
- Dairy: Cake slice has 5 g of dairy, Dark chocolate has 0 g. Milk proteins can act like growth signals in the skin.
- Skin boost: Cake slice gets +0.8 from omega-3 and polyphenols, Dark chocolate gets +5.
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, dark chocolate is the better pick of the two. A 37-point gap is the kind of swap that can show up in your skin within a week or 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.
