What actually happens to your face as you age and how do you know which skincare products or aesthetic treatments your skin really needs?

In this conversation, Dr. Harshna Bijlani explores the science behind skin aging, aesthetic medicine, skincare and the growing world of treatments such as Botox, fillers, lasers, collagen boosters and biostimulators.

As a leading skin and aesthetic physician and Founder of The AgeLess Clinic, Dr. Bijlani explains why good skin treatment begins with understanding the person rather than simply treating what appears on the surface. She explains what actually changes beneath the skin as we grow older, including changes in bone structure, facial fat, collagen, elasticity and pigmentation. She also breaks down the difference between Botox, fillers, threads, collagen boosters and biostimulators, why each treatment has a different purpose and why knowing when not to treat can be just as important.

The conversation also explores:

• Why dark circles are not always caused by lack of sleep

• How using too many skincare actives can sensitise and damage the skin barrier

• The simplest skincare routine before spending heavily on treatments

• What Botox, fillers, threads, collagen boosters and biostimulators actually do

• How bone, fat pads, collagen and elasticity change as the face ages

• Why sun exposure and pigmentation matter particularly for Indian skin

• How perimenopause and menopause can affect dryness, elasticity and skin quality

• The relationship between diet, sugar, insulin resistance and visible skin changes

• How rapid weight loss can change facial volume and skin laxity

• Lasers, energy-based devices, microneedling, peels and medical-grade facials

• Regenerative approaches including PRP, exosomes and newer aesthetic treatments

• Why over-treating the face can lead to unnatural results

• How treatment stacking is planned for major appearances, including Deepika Padukone’s Cartier show

• Why the right aesthetic treatment should preserve your natural proportions rather than change your identity
