INTRODUCTION: Calcium hydroxyapatite in a carboxymethylcellulose carrier gel presents unequivocal results for facial skin improvement, stimulating the collagen and elastin production. Regulatory agencies recently approved its use after scientific proof of its benefit in greater dilution.
OBJECTIVE: This study aimed to demonstrate a technical standardization to rationalize body application. Methods: This study idealized vectorized figures to apply calcium hydroxyapatite with intermediate dilution (1:4).
RESULTS AND DISCUSSION: The proposed technique makes it possible to accurately calculate the required for each patient, depending on the anatomical unit’s size to be treated and the region’s topographic characteristics. This technique’s rationale also allows homogeneous distribution, minimization of complications due to product accumulation, good tolerability by the patient and optimization of results.
CONCLUSIONS: The vectorized figures’ technical simplicity facilitates calcium hydroxyapatite application, and customizations must be made with the injector’s greatest experience.

Eyebrow ptosis presents a significant challenge for cosmetic professionals. Minimally invasive procedures can improve eyebrow positioning; however, a thorough understanding of its varied etiologies is essential. The primary causes include skin laxity, muscular dysfunction, and tissue deflation, with the latter subdivided into frontal, temporal, and superciliary deflation. A precise diagnosis allows for the appropriate indication of microfocused ultrasound, botulinum toxin, biostimulators, and hyaluronic acid-based fillers, either as standalone treatments or in combination. At the end of this review, a treatment algorithm for eyebrow ptosis is proposed.
