Te Hidden Connection Between Glucose Levels and Dermal Health

Insulin Resistance and Growth Factor Signaling

In acanthosis nigricans, elevates insulid binds to receptors on keratinocytes and dermal fibrobblasts, spustiering proliferation. This leads to papilomatosis and hyperkeratosis. The condition is a visible marker of hyperinsulinemia long before glucose levels estae frankly dispetic. Insulin- like growth factors-1 (IGF- 1) receptors also play a role, creating a hyperplastic responsain theis.
