Cut sugar for 60 days. Skin is noticeably firmer and the dullness I'd had for years is gone.

Cutting added sugar intake below 25g per day. Excess glucose attaches to collagen and elastin through glycation, forming advanced glycation end products (AGEs) that make skin stiff, dull, and prone to sagging. Reducing sugar intake is one of the most impactful dietary changes for long-term skin quality and slowing visible aging.

Acne cleared up within 3 weeks of dropping sugar. Didn't realize how much it was driving inflammation.
