Accurate assessment of acne severity is essential for determining the appropriate treatment required. This paper reviews photographic methods for such assessment. Literature included met the following criteria: proposed photographic standards to assess acne, evaluated such standards, or offered photographic methods to improve visualization and assessment. Validity was evaluated by comparing given photographic grading methods to other methods, such as lesion counting. Many photographic standards… 

Acne image analysis: lesion localization and classification

The processes of region-ofinterest determination using entropy-based filtering and thresholding as well acne lesion feature extraction using discrete wavelet frames and gray-level co-occurence matrix were presented and their effectiveness in separating the six major acne lesions classes were discussed.

Automated detection, extraction and counting of acne lesions for automatic evaluation and tracking of acne severity

A prototype application for automatic acne detection, lesion counting and reporting through the processing of distance picture taken by mobile devices is developed.

Development and clinical validation of a novel photography‐based skin pigmentation evaluation system: a comparison with the calculated consensus of dermatologists

A novel photography‐based skin pigmentation evaluation system is developed and validated its accuracy and reliability with a newly proposed method.

Emerging High-Frequency Ultrasound Imaging in Medical Cosmetology

A narrative review of literature from PubMed and Web of Science published between 1985 and 2022 focuses on the progression of HFUS imaging in medical cosmetology, especially on its promising application in the quantitative evaluation and differential diagnosis of cutaneous pathological scar, port wine stain, acne, skin aging, and other cosmetic applications.

Clinical Considerations of Bioequivalence for Topical Dermatologic Drugs

This chapter explores many current methods to assess bioequivalence (BE) between dermatologic drugs and discusses the possibilities that visual inspection and knowledge of the steps of percutaneous penetration provide in developing a standardized method of determining BE for topical drugs.

Improvements in metrics, especially for early assessment, emphasizing clinical relevance, are necessary to increase success rate and focused attention on how preclinical and early clinical studies failed to indicate subsequent toxicity profiles in patients would accelerate drug development.

Acne vulgaris

New treatment options with a shift towards targeting the early processes involved in acne development instead of suppressing the effects of end products will enhance the ability to improve the outcomes for patients with acne.

It would be a mistake to replace the current standard of lesion counts with their system for many reasons, including the fact that photographic evaluation is inherently more subjective than an actual count.
