Skin Concerns
Understanding Actinic Keratoses
Pre-cancerous lesions, also known as actinic keratoses (AKs), are common skin lesions associated with cumulative exposure to ultraviolet (UV) radiation from the sun or artificial sources such as tanning beds. These lesions often appear as rough, scaly patches on sun-exposed areas including the face, scalp, ears, neck, arms, and hands.
Although actinic keratoses are not skin cancer, some may progress to squamous cell carcinoma if left untreated. At Beauty by Doctor (BBD), located in Bondi Junction, Sydney's Eastern Suburbs, we prioritise early assessment and management of sun-damaged skin and actinic keratoses. Our clinic, led by Medical Director Dr Phoebe Jones, offers treatment options for selected patients, including photodynamic therapy (PDT) and UltraClear.
What Causes Actinic Keratoses
Actinic keratoses develop as a result of cumulative sun damage, which can lead to changes in the skin's outer layer. Risk factors include prolonged UV exposure, fair skin, light eyes, and a history of frequent sun exposure.
Age is also a contributing factor, as AKs are more commonly seen in older adults due to accumulated sun damage over time, although younger individuals with significant sun exposure may also develop them.
Immune suppression may increase risk. This can include people taking immunosuppressive medications or those with medical conditions that affect immune function.
Genetic factors may also play a role, particularly where there is a family history of skin cancer or actinic keratoses.
Impact of Actinic Keratoses
Actinic keratoses may be asymptomatic, but some can become dry, tender, irritated, or more noticeable over time. Because these lesions are associated with chronic sun damage and may, in some cases, progress to skin cancer, assessment and treatment are important.
Treatment Options for Actinic Keratoses
Photodynamic Therapy (PDT)
Photodynamic therapy (PDT) is a treatment option that combines a photosensitising agent with a specific light source to target abnormal skin cells. The photosensitising agent is applied to the treatment area and, after an incubation period, activated with light. This process targets sun-damaged and abnormal cells while aiming to preserve surrounding tissue. PDT may be considered when multiple actinic keratoses or broader areas of sun damage are being treated.
UltraClear
UltraClear is a fractional laser platform that may be used in selected cases to treat sun-damaged skin and actinic keratoses. It works by delivering controlled laser energy to targeted areas of the skin, with the aim of supporting skin renewal and removal of abnormal tissue. Treatment suitability depends on the location, extent, and clinical assessment of the lesion or affected area.
Any lesion that appears atypical, changes rapidly, bleeds, or does not heal may require further medical assessment before treatment is considered.
Suitability for treatment is determined during consultation. All medical and cosmetic procedures carry risks, and outcomes vary between individuals. While complications are uncommon, it is important that potential risks, including rare adverse events, are understood.
