Myths vs facts: Glukose and Haut

The idea that sugar directly causes skin issues like acne or wrinkles is an oversimplification. There is some evidence that a high glycemic load can increase insulin and IGF-1, which may stimulate sebum production and contribute to acne. However, the effect is modest and varies between individuals. For skin aging, the concept of glycation – where sugar molecules bind to collagen, reducing elasticity – is supported by in vitro and animal studies, but human evidence is limited and confounded by other lifestyle factors. No validated consumer test (DNA, microbiome, or blood glucose) can reliably predict or guide personalized skin care based on glucose metabolism. MyBody-X does not offer a specific glucose-skin test. For skin concerns, consult a dermatologist and focus on a balanced diet. Evidence level: mechanistic to human-moderate, not strong.
