Healthy skin is a reflection of how well it functions. From acting as a protective barrier to retaining moisture and supporting healing, the skin plays a vital role in overall health. We spoke with Dr. Karishma Ballani to understand what defines healthy skin and how science-backed skincare and professional treatments like Hydrafacial can help maintain it.

Q. When we talk about “healthy skin,” what does that actually mean?

Dr. Karishma Ballani: Healthy skin is skin that functions well. It’s well-hydrated, has a strong barrier, an even texture, and is able to protect the body from environmental stressors such as pollution, bacteria, and UV radiation. While glowing skin is often associated with good health, true skin health goes much deeper than appearance.

Q. What factors influence the health of our skin?

Dr. Karishma Ballani: Skin health is influenced by a combination of intrinsic and extrinsic factors. Intrinsic factors include genetics and the natural ageing process, while extrinsic factors include sun exposure, pollution, stress, sleep, diet, smoking, and skincare habits.

Although we can’t control every factor, we can certainly support our skin through consistent skincare, healthy lifestyle choices, and appropriate professional treatments.

Q. Why is the skin barrier so important?

Dr. Karishma Ballani: The skin barrier is your body’s first line of defence. It helps retain moisture while protecting the skin from irritants, allergens, and harmful microorganisms. When the barrier becomes compromised, the skin may feel dry, irritated, sensitive, or more prone to breakouts.

Supporting the skin barrier is one of the most important goals of any skincare routine.

Q. What role does hydration play in maintaining healthy skin?

Dr. Karishma Ballani: Hydration is fundamental to healthy skin. Well-hydrated skin tends to feel smoother, appear more radiant, and function more effectively as a protective barrier.

However, hydration isn’t just about drinking enough water. It’s also about maintaining the skin’s moisture balance through appropriate skincare and treatments that replenish hydration where it’s needed.

Treatments such as Hydrafacial help support this by infusing the skin with hydrating ingredients while improving overall skin quality.

Q. Can healthy skin be achieved through skincare products alone?

Dr. Karishma Ballani: Home skincare is essential, but it’s only one part of the equation. Cleansing, moisturising, and sunscreen should form the foundation of every routine. Professional treatments can complement this by providing deeper cleansing, exfoliation, hydration, and customized care that topical products alone cannot always achieve.

The best results come from combining daily skincare with periodic professional maintenance.

Q. Where does Hydrafacial fit into a skin health routine?

Dr. Karishma Ballani: I think of Hydrafacial as a skin health treatment rather than simply a cosmetic facial. It combines cleansing, gentle exfoliation, painless extraction, hydration, and targeted serum infusion in one session.

Because it’s customizable and suitable for most skin types, it can be incorporated into a long-term skincare plan to help maintain healthy, refreshed skin throughout the year.

Q. How does exfoliation contribute to healthier skin?

Dr. Karishma Ballani: Our skin naturally sheds dead cells, but this process slows down with age and environmental stress. Gentle exfoliation helps remove this build-up, allowing healthier skin to surface and improving the absorption of skincare products.

The key is choosing an exfoliation method that’s appropriate for your skin type. Treatments like Hydrafacial provide controlled, gentle exfoliation without being overly aggressive.

Q. Can professional skin treatments help even if someone doesn’t have a specific skin concern?

Dr. Karishma Ballani: Absolutely. Professional skin treatments aren’t only for addressing problems—they’re also valuable for maintaining healthy skin.

Just as we visit the dentist for routine check-ups rather than waiting for a problem to develop, regular skin maintenance can help support skin health and identify concerns early.

Q. What are the biggest mistakes people make when trying to achieve healthy skin?

Dr. Karishma Ballani: One common mistake is chasing trends rather than understanding what their own skin needs. Another is expecting quick results from a single product or treatment.

Healthy skin is built through consistency—using sunscreen daily, following an appropriate skincare routine, avoiding unnecessary irritation, and choosing treatments based on professional advice rather than social media recommendations.

Q. What advice would you give someone who wants healthier skin?

Dr. Karishma Ballani: Start simple. Cleanse your skin gently, moisturize regularly, wear sunscreen every day, and seek professional advice if you’re unsure what your skin needs.

If appropriate, incorporating professional maintenance treatments such as Hydrafacial can complement your daily routine by supporting hydration, improving skin texture, and helping maintain overall skin health.

Q. What’s one message you’d like readers to take away?

Dr. Karishma Ballani: Healthy skin isn’t about perfection—it’s about function. When your skin is well cared for, protected, and supported consistently, it naturally looks healthier too.

Rather than chasing short-term trends or instant results, focus on building habits that support your skin over time. Small, consistent steps—combined with professional guidance when needed—will always have the greatest impact on your skin’s long-term health.
