Why it matters
The food-skin connection is one of the most debated topics in dermatology — for decades doctors dismissed it, and increasingly the evidence says they were wrong. Dairy, high-glycaemic foods, and certain inflammatory foods have documented associations with acne in research. But the relationship is highly individual. The food that breaks one person out might have no effect on another. Without tracking the specific relationship between your diet and your skin over time, the connection is impossible to confirm — dermatologists rarely ask about food and the delay between eating a trigger food and seeing a breakout is usually 48 to 72 hours, making it completely non-obvious.
When Normal helps
Normal tracks your diet alongside your skin condition over time. It finds which specific foods or food patterns consistently precede your breakouts and confirms the relationship across enough data points to be confident. The 48 to 72-hour lag is something Normal accounts for automatically.
How Normal finds it
Tell Normal what you eat and how your skin is looking. Over four to six weeks it has enough data to find the specific dietary pattern that's most consistently associated with your breakouts. Most people find one or two specific foods they'd never suspected.
