Can You Reverse Sun Damage?

Living in Australia means enjoying plenty of sunshine, but our skin often pays the price. In Brisbane, where ultraviolet (UV) exposure is particularly high, sun damage is something I see almost every day in clinical practice.

The good news is that some of the visible and precancerous effects of sun damage can be treated, although treatment cannot simply erase a lifetime of UV exposure.

Acute vs Chronic Sun Damage

Sun damage can broadly be considered acute or chronic.

Acute damage includes episodes of significant sunburn, particularly blistering sunburn. Repeated or severe UV exposure—especially during childhood and adolescence—is associated with an increased lifetime risk of skin cancers, particularly melanoma. UV exposure also contributes to the development of basal cell carcinoma (BCC).

Chronic sun damage is different. It develops gradually through cumulative UV exposure over many years. It can cause pigmentation, uneven skin tone, redness, loss of elasticity, wrinkles, roughness and precancerous lesions such as actinic keratoses (solar keratoses).

How quickly this occurs varies considerably between individuals. Someone with Fitzpatrick skin type I, who burns very easily and has relatively little natural protection from UV radiation, can develop significant photodamage much earlier than someone with deeply pigmented Fitzpatrick type VI skin. However, no skin type is completely protected from UV damage or skin cancer.

In Australia—and particularly sunny Queensland—the cumulative exposure can be substantial.

Can Sun Damage Actually Be Reversed?

To some extent, yes—but it depends on what we mean by sun damage.

Some pigmentation, redness, texture changes and signs of photoageing can be substantially improved. Precancerous changes such as actinic keratoses can also be actively treated.

However, sunscreen alone cannot remove established actinic keratoses, significant solar pigmentation or existing structural skin damage. Its primary role is to reduce additional UV injury.

Treatment therefore starts with determining exactly what type of damage is present.

Seeing What the Sun Has Done to Your Skin

At SKEEN, we can assess sun damage clinically and use advanced imaging to obtain considerably more information about the skin.

Vectra 3D total-body imaging can document the skin and individual lesions across the body, providing an important baseline for ongoing surveillance.

For facial skin, VISIA imaging can demonstrate features including pigmentation, UV-related changes, redness and other aspects of skin quality that may not be as obvious when simply looking in the mirror.

This allows us to move beyond simply saying that someone’s skin is “sun damaged.” We can identify what type of damage is present and how extensive it is, then determine whether treatment is worthwhile.

Treating Established Sun Damage

Treatment needs to match the problem.

Depending on the findings, management may include prescription or medical topical treatments, treatment of actinic keratoses, field therapy for more extensive sun damage, and selected laser or energy-based treatments for pigmentation, redness, texture and photoageing.

A person with a few solar spots requires a very different approach from someone with extensive field change and numerous actinic keratoses.

This is also why treating pigmentation cosmetically without first establishing what the lesions actually are isn’t always sensible. Diagnosis comes before treatment.

And Don’t Forget Sunscreen

A good broad-spectrum sunscreen remains one of the most important parts of preventing further photodamage and reducing UV exposure.

But sunscreen isn’t a force field, and it shouldn’t be considered a treatment for everything the sun has already done. Correct application, adequate quantity, reapplication and other sun-protective measures—including clothing, hats, shade and avoiding excessive UV exposure—remain important.

If you already have significant sun damage, the best approach is usually a combination of assessment, prevention and targeted treatment.

The Australian sun may be difficult to avoid completely, but that doesn’t mean we have to ignore the damage it leaves behind.
