Photodynamic therapy eliminates sun spots and treats baldness

Photodynamic therapy eliminates sun spots and treats baldness

Photodynamic therapy was first used in the year 1900 by Raab. This treatment consists of the use of a chemical substance that can be applied by the mouth, vein or through products in the form of cream or solution.

Such a product has the ability to penetrate into tissues / cells that have changes in their metabolism, such as, cancers and some diseases like acne, hidradenite, folliculitis, and others. This medication becomes a byproduct, in general, the so-called protoporphyrin IX, taking advantage of the formation of free radicals / singlet oxygen and it concentrates after a certain time within the lesions. The higher the metabolism or the cellular alteration, the greater the amount of protoporphyrin produced / accumulated. Therefore, we often play around and say that it concentrates where it is "spoiled."

Photodynamic therapy may require up to 20 days of care, with peeling and redness of the skin

After a certain period (depends on the product chosen and (usually the light produced by a LED - Light Emitting Diode) irradiating the area to be treated, destroying the sites where protoporphyrin accumulation has occurred. So, this method would remember the precision of a scalpel blade, destroying only the affected area and to varying degrees depending on the damaged tissue, for example, the tumor to be destroyed. In dermatology we use creams or alcoholic solution specifically prepared for this. treatment, officially its main indication is basal cell carcinoma and a specific variety of premalignant skin lesions called actinic keratoses. Among the "off-label" / "not yet approved" treatments are those for acne (pimples), hidradenites, folliculitis, some rarer diseases such as scleroderma and for skin rejuvenation.

It should be remembered that is a treatment that may be mildly painful depending on skin changes, depth, wound extension, and protoporphyrin production. Topical or injectable anesthesia helps a bit, but in more severe cases the pain is more severe.

In the post-procedure period, preventive medication may be needed depending on the region being treated to avoid bacterial and viral infections and the treated area swollen, red, and sunlight-sensitive for at least 48 hours after the photodynamic therapy session. The recovery of this treatment, for example, on the face, when well done (depends on the doctor's goal), may require up to 20 days of care, with peeling and redness of the skin.

It is considered as a first line treatment and presents an incomparable result when well indicated in the treatment of sun-damaged skin with the presence of actinic keratoses (pre-malignant lesions) in the region of the scalp (bald patients) and face, avoiding the sequelae of multiple surgeries for individual wound removal .

This is a treatment that must be performed by experienced physicians with the correct equipment and medications to achieve the expected results.
