Study Objectives: 

To investigate the effectiveness and tolerance of Natucain Eyebrow solution treatment, active 7%  MKMS24, in the treatment of an eyebrow enhancement using non-invasive technologies. 

Study Design 

This was a randomized, blinded, intra-individual comparative study. A total of 29 subjects participated  in the cosmetic trial that was conducted at New Flag GmbH, Munich. The study started in April and  ended in July 2021 with a duration of 12 weeks.  

Background 

The beauty industry has grown exponentially in the past decade, and so have the products available to  consumers. Eyebrow enhancer is a beauty product that helps to make the eyebrows fuller and denser.  The active ingredients can be found in lotions, creams, ointments and serums. 

In this cosmetic trial, the investigators aim to confirm effectiveness and tolerance of Natucain Eyebrow solution treatment, active 7% MKMS24, in the treatment of an eyebrow enhancement using non invasive technologies. Natucain contains MKMS24, a unique patented (Patent No. EP3355992) anti-hair loss active and a hair enhancement that is based on Lentil, Thyme and Bamboo and 100%  natural origin. 

MKMS24 strongly stimulates the dermal papilla for the production of fibroblast growth factor 7 (FGF7)  and the Noggin protein by using newest biotechnologies which extends the anagen and shortens the  telogen phase, whilst ensuring there are sufficient nutrients to allow the hair follicle to regenerate. Noggin has an indirect function, inhibits the activity of the bone morphogenetic protein 4 (BMP4), with  a suppressive role in the transition from the Telogen phase to the Anagen. 

FGF7 directly stimulates the dermal papilla to start a new hair cycle. 

Patients and Methods 

The subjects were 29 voluntary patients with fair eyebrows at the company New Flag in Munich. In the  last 90 days, the volunteers did not have previous treatments to confirm the efficacy of the treatment  based on Natucain Eyebrow Solution, active 7% MKMS24. Subjects applied the product twice a day,  morning, and evening, according to the manufacturer’s instructions for a period of 12 weeks.  

In addition, the study assessed the number of hair follicles at different stages of the eyebrow growth  cycle using non-invasive technologies and evaluated the properties of Natucain Eyebrow Solutions, 

with the questionnaire being voluntary. The parameters to be studied were evaluated through  examinations, instrumental methods and a questionnaire applied by professionals. The aim of the  questionnaire was, on the one hand, the subjective assessment of the product respectively cosmetic  acceptance of the formulation and, on the other hand, the subjective evaluation of the product efficacy  (increase in capillary volume). During the study period, adverse reactions such as burning, itching, and  peeling, as well as possible contraindication to the product were evaluated. Also, no additional hair  growth hormones or skin care creams with silicone were used during this time frame. 

The selected patients of the study had to fulfil the following characteristics: 

• Volunteers diagnosed with weak eyebrowes, 
• Age between 20 and 65 years, 
• No change in hormone therapy during the last 90 days or during the study, • No topical or systemic treatments at the beginning of the study and/or 90 days before, • No history of intolerance to topical products, and 
• Signing of informed consent. 

The study excluded patients with at least one of the following traits: 

• Pregnancy or lactation, 
• Current treatment for eyebrow and eyebrow in the last 6 months 
• Diagnosis of Sars Cov-2 in the past 90 days 
• History of allergic reactions to the product which is used 
• Medication that may alter the parameters to be evaluated 

The patients were evaluated on week 0, week 6, and week 12.  

The products were delivered with the manufacturer’s instructions. It was instructed to issue a warning  if any complaints arose and not to use any products that interact with the study (other treatments for  eyebrow enhancement etc.). Eyebrow growths were documented using photographs taken in week 0,  6 and 12. 

Results 

The products were delivered with the manufacturer’s instructions. It was instructed to issue a warning  if any complaints arose and not to use any products that interact with the study (other treatments for  eyebrow enhancement etc.). 29 volunteers (female only; age between 23 and 38 years; 25 Caucasian,  3 Caribbean, 1 African) 

The subjects were 29 voluntary subjects with weak eyebrows at New Flag GmbH, Munich. In the last  90 days, the volunteers did not have previous treatments to confirm the efficacy of the treatment  based on Natucain Eyebrow Solutions, active 7% MKMS24. Subjects applied the product twice a day,  morning, and evening, according to the manufacturer’s instructions for a period of 12 weeks.  

In addition, the study assessed the number of eyebrow follicles at different stages of the hair growth  cycle using non-invasive technologies and evaluated the properties of Natucain Eyebrow Solutions,  with the questionnaire being voluntary. The parameters to be studied were evaluated through  examinations, instrumental methods and a questionnaire applied by professionals. The aim of the  questionnaire was, on the one hand, the subjective assessment of the product respectively cosmetic 

acceptance of the formulation and, on the other hand, the subjective evaluation of the product efficacy  (The primary end point was eyebrow prominence assessed by the investigator eyebrow assessment).  During the study period, adverse reactions such as burning, itching, and peeling, as well as possible  contraindication to the product were evaluated. Also, no additional hair growth hormones or skin care  products with silicone were used during this time frame. 

Statistical Analysis 

Eyebrow growths were documented using photographs taken in week 0, 6 and 12.  The primary end point was eyebrow prominence assessed by the investigator eyebrow assessment. Secondary efficacy measures included eyebrow length measured by digital image analysis and  volunteers-reported outcomes. Safety data included adverse event monitoring. The parameters to be  studied will be evaluated through examinations, instrumental methods and a questionnaire. Hair density and analyse the eyebrow growth of each eyebrow part (head, body, and tail) in week 0, 6  and 12. Each eyebrow area is quantified, and the mean values calculated.

Best measured result (Week12) 

In summary, this study confirms the previous observations that hair density, diameter, pattern of  growth, and hair growth cycle vary according to their anatomical location within the eyebrow. The volunteers noticed improvement in the appearance, length and volume-density within 4 weeks. One volunteer applied the product only on the brow area. 

One volunteer didn’t notice any improvement of the eyebrow. 

The cosmetics aspect of the product was accepted by most volunteers. 

The majority (90.00%) of volunteers would continue to use the product. 

The majority (79,00%) of volunteers would recommend its use. 

None of the results presented above were associated with treatment response. Also, the response to  the treatment was independent of the ethnic background and age of the subject. There were no  adverse effects associated with the use of the product.
