PCOS raises androgens and insulin resistance, driving jawline acne, excess hair, scalp thinning and dark skin patches together.

Key takeaways

• PCOS raises androgens and often insulin resistance, both of which directly affect skin and hair.
• PCOS acne classically concentrates along the jawline and resists standard over-the-counter treatment.
• Dark, velvety neck and underarm patches (acanthosis nigricans) signal underlying insulin resistance.
• Combining hormonal treatment with targeted topical care gives more durable results than skincare alone.
