Is HbA1c useful for Haut?

HbA1c is a well-established marker for average blood glucose control over the past 2–3 months, primarily used for diagnosing and monitoring diabetes. Its relevance to skin health is indirect: chronically elevated blood glucose can contribute to skin issues such as delayed wound healing, dryness, infections (e.g., fungal), or diabetic dermopathy. A normal HbA1c indicates good metabolic control, which can positively affect skin. However, HbA1c is not a direct skin marker – it does not measure specific skin parameters. MyBody-X does not offer an HbA1c test; if you want to measure it, a doctor visit or separate lab test is needed. The evidence for HbA1c's usefulness regarding skin is indirect and based on diabetes research. For targeted skin analysis, other biomarkers (e.g., AGEs, inflammatory markers) are more appropriate.
