Abstract

Solid lipid microparticles (SLMs) represent a promising approach for drug delivery in anti-acne applications. In this study, asiatic acid-loaded SLMs (AASLMs) were prepared by melt emulsification method in conjunction with freeze-drying. Comprehensive evaluations comprised particle size, %entrapment efficiency (%EE), %labeled amount (%LA), surface morphology, stability, %release, %skin permeation, and anti-acne activity. The AASLMs exhibited an average particle size ranging from 7.46 to 38.86 µm, with %EE and %LA falling within the range of 31.56 to 100.00 and 90.43 to 95.38, respectively. The AASLMs demonstrated a spherical shape under scanning electron microscopy, and maintained stability over a 3-month period. Notably, formulations with 10 % and 15 % cetyl alcohol stabilized with poloxamer-188 (specifically F6 and F12) displayed a minimum inhibitory concentration (MIC) value of 75 mg/ml against Cutibacterium acnes. Furthermore, F12 exhibited a higher %release and %skin permeation compared to F6 over 24 h. In a single-blind clinical trial involving fifteen participants with mild-to-moderate acne, F12 showcased its potential not only in reducing porphyrin intensity and enhancing skin barriers but also in significantly improving skin hydration and brightness. However, further investigations with larger subject cohorts encompassing diverse age groups and genders are necessary to thoroughly establish the performance of the developed AASLMs.

  • The antimicrobial and anti-acne potential of asiatic acid against C. acnes and S. aureus, coupled with its ability to inhibit STAT3-linked inflammation, positions C. asiatica favorably for managing acne-prone skin.

    “Furthermore, the antimicrobial and anti-acne potential of asiatic acid, particularly against C. acnes and S. aureus, coupled with its ability to inhibit STAT3-linked inflammation, positions C. asiatica favorably for managing acne-prone skin (Chutoprapat et al. 2024; Wu et al. 2025).”
  • Triterpenoid saponins from C. asiatica, upon hydrolysis, yield aglycones that promote collagen and hyaluronic acid synthesis, exhibit anti-inflammatory and anti-elastase activities, and possess antioxidative properties critical for scar control and anti-aging benefits.

    “Central to the pharmacological activity of C. asiatica are triterpenoid saponins, which upon hydrolysis yield aglycones that promote collagen and hyaluronic acid synthesis, exhibit anti-inflammatory and anti-elastase activities, and possess antioxidative properties critical for scar control and anti-aging benefits (Shen et al. 2019; Kim et al. 2021; Chutoprapat et al. 2024; Zhang et al. 2024; Alam”
  • SLNs, NLCs, nanoemulgels, and SLMs have been extensively utilized to encapsulate C. asiatica actives.

    “Solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs), nanoemulgels, and solid lipid microparticles (SLMs) have been extensively utilized to encapsulate C. asiatica actives.”
  • SLMs tailored for acne treatment improved asiatic acid stability and showed controlled release and anti-acne effects in vitro and in vivo.

    “SLMs, tailored for acne treatment, improved asiatic acid stability and showed controlled release and anti-acne effects in vitro and in vivo (Chutoprapat et al. 2024).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
