What to watch with HLA-DQ2 and skin aging?

HLA-DQ2 is a genetic marker strongly linked to celiac disease. Some research suggests a possible connection to skin aging via chronic inflammation or oxidative stress in untreated gluten sensitivity. However, the evidence is weak and mostly based on observational studies or mechanistic reasoning. There are no robust clinical data proving a direct causal effect of HLA-DQ2 on skin aging. Moreover, the effect size of a single marker is small; skin aging is influenced by many factors (UV exposure, lifestyle, hormones). A genetic test for HLA-DQ2 alone is therefore not suitable for assessing skin aging risk. Be cautious of exaggerated marketing claims. A holistic approach including diet, sun protection, and skincare is more evidence-based.
