Australia records some of the highest ambient ultraviolet (UV) levels in the developed world. Across Brisbane and the Gold Coast the daily UV index regularly reaches very high to extreme for months at a time, and according to the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), UV in much of Queensland is at a skin-damaging level for most of the daylight hours throughout the year. That climate is not a backdrop to a skin plan. It is the central variable.
Cancer Council Australia notes that up to about 90 percent of visible skin ageing (fine lines, loss of firmness, pigmentary change, uneven texture, vascular markings) is attributable to UV exposure rather than chronological age. Photoageing is, in other words, mostly preventable, and the daily inputs that prevent it are also the ones that protect against skin cancer.
What UV actually does in skin
Solar UV reaches the skin in two main wavelengths relevant to ageing. UVB is shorter, more energetic, and primarily damages the surface layers. It is the main driver of sunburn and of direct DNA damage in keratinocytes, which underpins much of the skin cancer risk profile. UVA is longer, penetrates more deeply into the dermis, and is the principal driver of photoageing. UVA passes through window glass, is present from sunrise to sunset, and is not blocked by cloud.
In the dermis, UVA exposure upregulates matrix metalloproteinases (MMPs), enzymes that break down collagen and elastin. Cumulative exposure drives the disorganisation of elastic fibres known as solar elastosis, increases free radical production, and contributes to pigmentary irregularity through melanocyte activation. Visible features of advanced photoageing (deep lines, leathery texture, persistent pigment, telangiectasia) are downstream of these biological events.
The Queensland reality
South-east Queensland sits between roughly 27 and 28 degrees south. Local UV reaches its peak between approximately 10am and 3pm in summer, but in midwinter the UV index in Brisbane can still climb to high or very high around the middle of the day. SunSmart and Cancer Council guidance is clear: sun protection is required whenever the UV index is 3 or above, which covers most of the calendar year locally.
Driving (even to and from work), school pick-ups, walking the dog, a Saturday morning coffee outside, and standard weekday outdoor incidentals all contribute to cumulative dose. Most skin ageing is not produced on holiday. It is produced in the unconsidered exposures of normal life.
What actually helps, in order of impact
- · A broad-spectrum SPF 30 or higher (SPF 50+ is widely recommended in Australia), applied generously every morning, including on cloudy days and indoor-heavy days, because UVA still reaches you through windows.
- · Re-application every two hours when outdoors, after swimming, and after heavy sweating. The first morning application is rarely enough on its own.
- · Physical protection: a broad-brim hat, sunglasses meeting AS/NZS 1067, sleeves, and shade during peak UV. Sunscreen is the last line, not the only one.
- · Topical antioxidants (such as vitamin C serum) under sunscreen, to mitigate oxidative damage from any UV that gets through.
- · Topical retinoids, used consistently and under medical guidance, which have strong evidence for improving photodamage over time.
These are not optional extras to in-clinic treatment. They are the substrate on which any in-clinic protocol either compounds or fails to hold.
Where in-clinic regenerative treatment fits
Regenerative protocols can meaningfully improve photodamaged skin: pigment, tone, texture and underlying collagen quality. None of that holds without the daily basics in place. A clinic-only approach without sun protection is a treadmill. With protection, the same protocol compounds.
Equally important, several regenerative treatments require strict UV avoidance in the early recovery window. Treating photodamaged skin and then exposing it without protection can drive post-inflammatory pigmentation, which is harder to resolve than the issue you were treating. Aftercare instructions are not optional in Queensland; they are the treatment.
When to see your doctor
Any new, changing or unusual skin lesion (asymmetry, irregular border, multiple colours, growth, bleeding) should be assessed by your GP or dermatologist. Cosmetic concerns sit alongside, not above, skin cancer surveillance. Cancer Council Australia recommends becoming familiar with your own skin and noting changes between checks. Skin cancer outcomes in Australia are heavily improved by early detection.
All cosmetic procedures carry risks. A consultation with a registered medical practitioner is required prior to any treatment. The most cost-effective intervention for visible ageing in this climate, however, costs the price of a tube of sunscreen and the discipline to use it.
