India, Feb. 3 -- No matter how expensive your skincare routine is, glowing skin cannot be built on a poor diet.

In an Instagram video shared on January 30, the dermatologist explains how these dietary culprits actively break down collagen, fuel inflammation, and accelerate visible signs of premature ageing.
