How sunscreen prevents premature ageing and protects your skin

Sun exposure and premature ageing
As much as sunshine feels woven into Australian culture, we now know prolonged sun exposure accelerates visible ageing.
Beyond skin cancer prevention, limiting UV exposure plays a major role in maintaining collagen, elasticity and even skin tone over time.
What research shows about sunscreen and ageing
An Australian study conducted over several years found that consistent and correct sunscreen use significantly reduced visible signs of photo-ageing.
Key findings from the study
• Participants who applied sunscreen daily showed little to no visible ageing • Those who used sunscreen inconsistently showed damage to deeper skin layers • Collagen and elastic fibres were particularly affected in the inconsistent use group
Photo-ageing refers to skin changes caused by UV exposure, including wrinkles, pigmentation and loss of firmness.
How UV radiation affects your skin
Different types of UV radiation impact the skin in different ways.
UVB radiation
• Primary cause of sunburn • Linked to most skin cancers
UVA radiation
• Penetrates deeper into the skin • Breaks down collagen and elastin • Leads to wrinkles, sagging and sunspots
This is why broad spectrum protection matters.
What to look for in a sunscreen
Broad spectrum protection
Choose a sunscreen labelled broad spectrum to ensure protection from both UVA and UVB rays.
Ingredient preference
Sunscreens generally fall into two categories:
• Chemical sunscreens • Mineral sunscreens such as zinc based formulas
Many modern formulas also include hydrating ingredients to support the skin barrier while protecting from UV damage.
Skin type matters
There are now sunscreen options designed for different skin types, including oily and acne prone skin. You no longer need to compromise comfort to stay protected.
Supporting your skin alongside sunscreen
While sunscreen is essential, healthy skin is better equipped to recover from environmental exposure.
A simple routine helps maintain barrier strength and hydration.
