Changes in Skin Color: Clinical Perspectives

2.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin Cancer01:30

Skin Cancer

4.5K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

14.3K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

    Area of Science:

    • Aesthetic dermatology and dermatologic surgery.
    • Energy-based devices for skin rejuvenation.
    • Novel treatment modalities for skin texture irregularities.

    Background:

    • Fractional radiofrequency (FRF) was developed as a lower-risk, reduced-downtime alternative to fractional lasers for skin resurfacing.
    • Pin-based FRF (pFRF) delivers focused radiofrequency energy into intact skin without microneedle insertion.
    • Traditional fractional ablative and nonablative lasers carry higher risks and downtime.

    Purpose of the Study:

    • To achieve expert consensus on best-practice protocols for treating common aesthetic indications using a novel pin-based fractional radiofrequency (pFRF) device.
    • To provide standardized treatment guidelines for practitioners.
    • To establish safe and effective parameters for pFRF skin resurfacing.

    Main Methods:

    • An international panel of 10 dermatologists and surgeons participated.
    • A modified Delphi method was employed, including questionnaires and discussions.
    • Consensus was reached through multiple rounds of communication until agreement was achieved.

    Main Results:

    • Standardized pFRF protocols were developed for acne scars, enlarged pores, skin texture, rhytides, and striae.
    • Specific device parameters, techniques, patient preparation, anesthesia, and post-treatment care are outlined.
    • Guidelines consider condition severity and Fitzpatrick skin type for tailored treatment.

    Conclusions:

    • Pin-based fractional radiofrequency (pFRF) without microneedles is a viable alternative to fractional lasers and radiofrequency microneedling for skin texture irregularities.
    • Patients generally tolerate the pFRF procedure and recovery well.
    • Protocols for treating five common aesthetic skin concerns using a novel pFRF device are provided.
