Science-First Dermatology & Clinical Skincare

This is a close-up look at a Microneedling with Radiofrequency (MNRF) treatment, one of the most effective procedures I use for acne scars. The combination of microneedles and radiofrequency energy stimulates collagen production deep within the skin to rebuild its structure and smooth out pits and uneven texture.

I need to be direct about this: collagen powders do not work as advertised. Your body can't absorb collagen whole. Instead, I explain how to naturally boost your body's own collagen production through diet, like with bone broth or 'elumbu soppu', and proven skincare ingredients like retinoids.

A very common myth is that shaving makes hair grow back thicker and darker. This is completely false. I explain the science with my colleague Dr. Santhoshi; shaving only cuts the hair at the surface, which creates a blunt tip that might feel coarse as it grows, but it doesn't change the hair's actual thickness or growth rate.

The popular 'two-finger rule' for applying sunscreen isn't always accurate. The amount of protection you get depends on applying enough product, about half a teaspoon for the face and neck. I demonstrate why the size of the sunscreen nozzle can make this rule misleading and how to ensure you're truly protected.

GFC, or Growth Factor Concentrate therapy, is an advanced treatment for hair loss and skin rejuvenation that I offer. Unlike PRP, GFC uses a high concentration of your own growth factors without the cells, leading to more consistent results with less inflammation. It is effective for hair restoration, reducing melasma, and treating acne scars.

Here is my simple, two-step recipe for curing dark spots with toothpaste. Step one: get some toothpaste. Step two: throw it away and see a dermatologist. Please do not put products meant for your teeth on your delicate facial skin; it will only cause irritation and make things worse.
