Certain ointments stimulate the body’s immune system to attack and destroy precancerous lesions or small superficial skin cancer. 

Liquid nitrogen is sprayed onto the lesion to freeze it between -20ºC to -40ºC, to the point where the tissue dies. Cryosurgery is generally limited to smaller tumors and pre-cancerous lesions.

This technique involves cutting out the skin cancer and can be used for many BCCs, SCCs, and melanomas. This procedure may produce a more cosmetically acceptable linear scar when compared to the flat scar and loss of pigment (Hypopigmentation) resulting from curette and cautery. Surgical excision also has a cure rate of over 90%.

PDT has many benefits which help improve the overall health, look and feel of your skin.

PDT can assist in avoiding surgical procedures to remove skin cancers later down the track by removing the precancerous lesions now. It can also provide some great cosmetic results for sun-damaged skin, acne, fine lines, and hyperpigmentation. PDT is a great treatment option for patients who require a larger field area to be treated such as the face, scalp, decolletage, arms, and backs of hands. It is also an ideal solution for patients who have had bad reactions to other topical treatments, such as Efudix.

Post-treatment your skin needs to be looked after and protected from the harsh UVA and UVB rays of the sun. Your doctor and laser skin therapist will give recommendations on how to improve and properly maintain your skin's overall health long-term.

If you have had a lot of unprotected sun exposure from a young age or spent a lot of time in the sun with sports, hobbies, work, etc. then you will start to see sun damage appear on your skin as the years go by.

PDT provides rejuvenation of the skin and the treatment can be customised to your individual needs. It can be repeated if necessary and does not prevent you from undergoing any other cosmetic, medical or surgical procedures in the future. PDT is a great preventative and maintenance treatment to lower your risk of developing skin cancer.

Patients must see a doctor for a skin check before considering a PDT treatment. Treatment can be performed after clearance from a skin doctor at Absolute Health & Skin Clinic and is suitable for most people. If PDT is recommended to you, you will need to book in for a complimentary consultation with our PDT & Laser Skin Therapist who will discuss the treatment in detail and provide you with all the necessary treatment information.

Photosensitivity

After treatment, you will be sensitive to light for 24 - 48 hours. It is important during this time that your exposure to the sun is minimal and it is best to stay indoors.

Skin Response

Skin response will vary with treatment parameters and each individual's skin condition and skin type. This visible healing process usually finishes between 7 to 14 days post-treatment. Cell regeneration and turnover will take up to 3 months post-treatment.

Days 1 - 3

Redness and swelling are to be expected, like a bad sunburn. Extreme sensitivity to light, so keep indoors and out of direct sunlight as much as possible.

Days 3 - 7

Swelling will subside. The treated area will be red, tender, and sometimes itchy. Your skin will peel, scab, or flake off.

Days 7 - 14

Peeling will be finished. Redness will diminish. The skin may still feel itchy, tight, and uncomfortable which is a normal part of the healing process. Depending on the treatment area and if the patient is using correct sun protection, the skin will be back to its normal skin tone within 2-3 weeks.
