Background and Objectives: The 1444 nm wavelength Neodymium:Yttrium–Aluminum–Garnet (Nd:YAG) laser treatment is an efficient method for treating axillary osmidrosis (AO); however, it has a relatively low treatment persistence. To address this issue, we performed integrated liposuction surgery with a laser to treat AO and compared the results with those of a group treated only with a laser. Materials and Methods: This study compared the outcomes of AO treatment between the two groups up to six months postoperatively. The first group of 18 patients underwent laser treatment alone, and the second group of 12 patients underwent integrated liposuction surgery in addition to laser treatment. Outcomes were assessed using the following variables: degree of malodor (DOM), sweating area, patient satisfaction, pain levels, and complications, such as burns, swelling, and contractures. Results: Compared to the laser-only group, the integrated liposuction group demonstrated significantly superior outcomes in terms of DOM (p = 0.002) and patient satisfaction (p = 0.006), as well as a reduction in the sweating area (p = 0.012). The pain rating was higher in the liposuction group, but the difference was not statistically significant (p = 0.054). Compared with the patients in the integrated liposuction treatment group, those in the laser treatment group exhibited a significantly higher number of burns under the axillae (p = 0.025). However, no significant differences were observed in the swelling or contracture between the groups. Conclusions: Integrated liposuction with laser therapy significantly improved treatment outcomes, including malodor, patient satisfaction, sweat test results, and decreased complication rates.

The impact of increasing age on body odor has become an important issue as our understanding of underlying skin changes in older people has increased. Therefore, cosmetic skin products especially for the needs of the elderly are of growing importance. This randomized single-blind crossover study assessed the deodorizing efficacy of two cosmetic products with different pH values on the age-specific odor of an elderly female subject panel (≥60 years). The two test products, adjusted to pH 4.0 and pH 5.8 were applied to the axillae once daily for three consecutive days after standardized washing of the axillae. The untreated axilla was used as a control. Six odor judges evaluated the efficacy of both products. Additionally, bactericidal and fungicidal activity was investigated with in vitro microbiologic tests. The pH 4.0 water in oil (W/O) emulsion significantly reduced axillary malodor in 44 elderly subjects at 8 and 24 h after treatment, compared with controls (untreated axillae) (p < 0.001 after 8 and 24 h), whereas pH 5.8 emulsion had no effect (p = 0.441 after 8 h; p = 0.425 after 24 h). Moreover, the pH 4.0 emulsion reduced axillary malodor at 8 and 24 h after treatment, compared with the pH 5.8 emulsion just narrowly missing statistical significance (p = 0.078 after 8 h; p = 0.053 after 24 h). Microbiologic in vitro tests showed that the pH 4.0 emulsion reduced the levels of odor-producing bacteria S. epidermidis and C. minutissimum after 1 h (2.98 log and 4.25 log). After 24 h, levels of S. aureus (>5.50 log), P. acnes (>5.30 log) and E. coli (>5.46 log) were further reduced whereas no effect was observed for pH 5.8. A pH 4.0 emulsion significantly reduced axillary malodor for up to 24 h after application in females aged at least 60 years. This reduction in malodor is very likely due to a reduction of odor-producing bacteria. Full article
