Your skin is the largest organ in the body and one of the most active. It regulates temperature, clears metabolic waste through sweat, responds to blood flow changes, and acts as a barrier against environmental exposure. When circulation is sluggish, sweat function is poor, or oxidative stress runs high, skin function can suffer.
HOCATT stands for Hyperthermic Ozone and Carbonic Acid Transdermal Therapy. It is a private, enclosed chamber session - 30 to 35 minutes - where the body is surrounded by therapeutic inputs while the head remains outside throughout. Modalities include: infrared sauna heat, transdermal ozone (delivered through the skin via steam - not IV, not oral, not rectal), CO2 bath, steam and humidity, PEMF, and photon light in red and near-infrared wavelengths.
Heat is one of the oldest and most well-studied tools for promoting skin circulation. When body temperature rises, peripheral blood vessels dilate, delivering more oxygen and nutrients to the skin layers and actively removing metabolic byproducts. Mooventhan and Nivethitha (2014) reviewed the physiological effects of thermal therapy, documenting evidence for improved peripheral circulation under heat exposure (PMID: 24926444). Sweating also supports surface clearance of accumulated residue - particularly relevant for FIFO workers and those in physical or outdoor roles in Perth, where skin exposure to dust, UV, and industrial residue is a real and ongoing issue. Some FIFO clients at the Wembley centre (open from 6am Monday) book specifically to clear their system after time on site.
Of all the Hocatt modalities, photon light - specifically red and near-infrared wavelengths - has the strongest published evidence base for direct skin effects. Avci et al. (2013) published a comprehensive review of low-level light therapy on skin, covering mechanisms of action and clinical evidence across wound healing, collagen production, and inflammation reduction (PMID: 24049929). Red and near-infrared light stimulates mitochondrial activity in skin cells, with downstream effects on fibroblast proliferation - the cells responsible for collagen and elastin synthesis. These effects are dose-dependent and relate to consistent, repeated exposure. Photon light therapy does not treat acne, eczema, rosacea or psoriasis.
The CO2 bath component introduces carbonic acid gas into the chamber, which absorbs through the skin. The physiological effect is vasodilation at the capillary level - the body responds to increased CO2 at the skin surface by dilating local blood vessels. Poor microcirculation is associated with dull, sluggish-looking skin and slower cell turnover. The CO2 bath works alongside infrared heat - both promoting circulation through different pathways, creating a more sustained circulatory response.
Bocci et al. (2011) documented the ozone paradox: controlled, low-level oxidative stress delivered through ozone exposure can stimulate the body's own antioxidant defence systems through upregulation of Nrf2-mediated pathways (PMID: 19890812). In skin terms, this is relevant because oxidative stress is a key driver of skin ageing and impaired barrier function. What transdermal ozone does not do: it does not systemically kill skin bacteria, does not treat dermatological infections, and does not function as a medical treatment for any named skin condition.
People complementing an existing skincare routine: Clients who want to improve the underlying physiological conditions that skincare products work with - circulation, sweat function and cellular activity - use Hocatt alongside their routines. Those dealing with skin that feels dull or congested: Stress, poor sleep, diet changes and environmental exposure all affect skin. Hocatt's combination of heat, light and circulation support addresses several of those drivers. Perth FIFO workers and tradespeople: Occupational skin stress from mine sites, construction and outdoor industrial roles means consistent exposure to UV, dust, and sweat accumulation. Hocatt sessions at East Perth and Wembley serve as a physiological reset - the Wembley centre opens at 6am on Mondays for early return rotations.
Is Hocatt safe for sensitive skin? The Hocatt chamber does not involve direct topical application. People with reactive or sensitive skin should disclose this at intake. If you have a diagnosed condition - rosacea, eczema, psoriasis - consult your GP or dermatologist before booking.
Can I use Hocatt with my skincare products? Arrive with clean skin - no heavy creams, oils or active ingredients. After the session, your skin will be warm and pores will be open - often an optimal time to apply hydrating products. Avoid strong actives (retinoids, high-percentage acids) on the same day.
How many sessions are recommended to notice a difference? Many clients report changes in how their skin feels - texture, congestion, tone - after a course of four to six sessions over three to four weeks. This is consistent with the photon light therapy literature, which shows cellular changes accumulating over repeated exposures.
Is this a replacement for dermatology? No. Hocatt at Beyond Rest is a wellness service, not a medical or dermatological clinic. It can be used alongside dermatological care but is not a treatment for any named skin condition.
What should I do in the 24 hours after a session? Hydrate well. Avoid heavy alcohol, high-sugar intake and UV exposure on the day of your session. Keep post-session skincare products hydrating and gentle rather than introducing strong actives.
