The conversation around skin health has quietly but decisively changed. Where clients once arrived at clinics asking for brighter skin or a smoother texture, they are now asking something more searching: why does my skin look tired, especially during summer? Why does it stop responding? The answer lies not in the products, but in what is happening beneath the surface, at a cellular level.
“People are recognising that skin quality is not only determined by what is applied superficially, but by inflammation levels, cellular energy production, circulation, oxygenation, and oxidative stress occurring beneath the skin,” says Dr Rohan Goyal, Founder and Regenerative Medicine Specialist, Nuvana. It is a distinction that is reshaping the aesthetics space and, with it, the therapies that clinics are now investing in.
Device-led therapies, among them Hydrogen Therapy, Ozone Therapy, and Contrast Therapy, sit at the centre of this shift. What makes them categorically different from traditional facials is not just the technology involved, but the depth at which they work. “Such device-led therapies use controlled medical technology to trigger biological responses that cannot be achieved through products alone,” says Dr Goyal. The results, he notes, are not about temporary radiance. “The outcome is often about improved skin behaviour over time: better hydration retention, reduced sensitivity, faster healing, improved tone uniformity, reduced inflammatory flare-ups, and healthier skin resilience.”
HYDROGEN THERAPY: THE ANTIOXIDANT FROM WITHIN
Of the therapies gaining traction, Hydrogen Therapy has attracted particular attention for the elegance of its mechanism. The treatment works through the inhalation of molecular hydrogen, one of the smallest antioxidant molecules. Once inhaled, they move rapidly through the body at a cellular level.
“Hydrogen rapidly diffuses into the mitochondria of each cell and penetrates deep into tissues,” explains Dr Goyal. The significance of this is difficult to overstate. Mitochondrial dysfunction is now strongly associated with accelerated ageing, dullness, and impaired skin repair. By addressing oxidative stress at this foundational level, the therapy supports what Dr Goyal describes as “cell rejuvenation, repair, and improved metabolic function.”
For the skin, the implications are visible: reduced dullness, improved hydration, more even tone, and a measurable decrease in stress-induced ageing. The therapy has become especially relevant in the context of Indian summers and monsoons, seasons that compound the skin’s inflammatory load considerably. “These seasons expose the skin to pollution, humidity, UV stress, and increased inflammation,making cellular-level antioxidant support not a luxury, but a clinical logic.” Dr Goyal notes.
OZONE THERAPY: INTERNAL PURIFICATION FOR TROUBLED SKIN
Ozone Therapy, long associated with detoxification in integrative medicine, has found a compelling application in skin wellness, particularly for acne-prone and congested skin during the season. The mechanism, as Dr Goyal explains it, operates through improved oxygen delivery to tissues, creating what he calls “an internal environment that supports purification and repair.”
The therapy’s antimicrobial and anti-inflammatory properties make it well suited to the challenges of humid weather, when bacterial imbalance and acne flare-ups are more prevalent. “By enhancing the body’s natural regenerative mechanisms, ozone therapy promotes healthier skin from within rather than only treating surface-level symptoms,” he says. Its scope extends beyond acne: Dr Goyal also points to its utility in addressing pigmentation and inflammatory conditions such as psoriasis, where “improved circulation and oxygen supply may help calm irritated skin and support healing.”
CONTRAST THERAPY: HEAT, COLD, AND VASCULAR TRAINING
Where Hydrogen and Ozone Therapies work through molecular and biochemical pathways, Contrast Therapy operates through the body’s response to temperature. “The process includes an infrared sauna, which works by heating the body from the core before warming the skin externally,” says Dr Goyal. This is followed by a regulated cold-water plunge, not an ice bath. “The water temperature is carefully customised by doctors based on the client’s physiology, tolerance, and health profile.”
This level of personalisation matters. Dr Goyal is direct about the risks of an undiscriminating approach: “Excessively cold temperatures may disrupt hormonal balance in certain individuals, especially women.” When administered correctly, however, the therapy offers significant benefit. “The alternating exposure between deep heat and controlled cooling stimulates circulation, lymphatic drainage, and vascular training.” Immediate results include reduced puffiness, improved skin tone, and an enhanced glow. Long-term, the benefits compound: “Better stress regulation, improved circulation, reduced inflammation, stronger skin resilience, and overall skin vitality.”
WHAT PROFESSIONALS NEED TO KNOW
For salon owners, spa directors, and clinic managers considering these modalities, Dr Goyal is clear that professional supervision is not optional. “Treatment protocols must align with the individual’s skin health and medical history.” He advises that clients and professionals must look for “medically supervised clinics, evidence-based technologies, hygiene standards, and practitioners trained in device safety and skin assessment.”
These therapies are, he notes, generally well tolerated across skin types but customisation remains central: “Medical assessment remains crucial to personalise intensity, duration, and treatment frequency based on the individual’s skin sensitivity and overall wellness profile.”
THE FUTURE IS REGENERATIVE
If there is a single thread connecting hydrogen, ozone, and contrast therapies, it is the movement away from cosmetic correction towards what Dr Goyal calls “preventive, regenerative, and wellness-based treatments.”
“Instead of only treating the visible symptom,” he says, “device-led therapies aim to improve the biological environment in which healthy skin is produced. This is where skin wellness is evolving.”
