Embodiment 1

[0434] Example 1 : Research on ammonia oxidizing bacteria used in human skin: cosmetic effects, safety, testing and skin metagenomics (Metagenomics)

[0435] A blinded, placebo-controlled study of 24 human volunteers randomized with 4:1 AOB and placebo was conducted. Subjects nitrosomonas suspension (10 9 CFU / ml, 2 times a day, a total of 3x 10 per day 10 CFU) was applied to his face and scalp for one week, and then followed for two weeks after application. Volunteers were instructed to avoid using hair products for one week of AOB application and one week after application, and then return to their usual shampoo use for the third week. Scalp swabs were obtained on day 0 as a baseline control and scalp swabs were obtained on days 1, 3, 8, 14 and 21 to assess the presence / absence of AOB by PCR and 16S rRNA sequencing analysis.

[0436] No serious adverse events were related to the AOB application that lasted for a week, and the product was deemed safe. AOB users reported clear im...

Embodiment 2

[0441] Example 2 : Placebo-controlled single, double-blind, randomized, multi-site cosmetic trial to evaluate the performance and tolerability of cosmetic products in improving the appearance of oily skin, facial pores and other cosmetic parameters in subjects with acne proneness

[0442] Phase 2b study:

[0443] AO+ spray (D23 eutrophic nitrosomonas preparation) treatment showed strong efficacy signals in both Skindex, investigator's global assessment and inflammatory injury count (adult group).

[0444] The AO+ spray formulation used in the test of Example 2 contained 50 mM Na 2 HPO 4 And 2mM MgCl 2 1x 10 in aqueous buffer solution 9 CFU / mL ammonia oxidizing bacteria.

[0445] Randomization (1:1:1:1) of B244 (D23 eutrophic nitrosomonas) in 36 adults (age 18+) with acne vulgaris in 4 weeks (two-week treatment, two-week interval) ) Double-blind placebo controlled dose range (2, 4, 8x 10 9 CFU) research. The study was 80% sure to detect a 30% net improvement in IGA (% subject improve...
