Insulin is a problem for most people with acne.
Up to 70% of acne cases have insulin playing a role, and most people have no idea. Theyāre treating their skin from the outside while the real driver is happening internally.
When you eat foods that spike your blood sugar repeatedly throughout the day, your insulin stays chronically elevated. Hereās what that does to your skin.
High insulin triggers a surge in androgens, the hormones that drive oil production in your pores. More oil means more congestion, more bacteria, more breakouts.
It also ramps up a growth factor called IGF-1, which accelerates skin cell turnover, clogs follicles, and fuels inflammatory acne.
And it promotes systemic inflammation, which makes existing breakouts angrier, redder, and slower to heal.
This is why you can be doing everything right topically and still breaking out every cycle. If insulin isnāt addressed, youāre managing symptoms, not the cause.
