Every number on this page carries one of these labels, so you always know where it came from.
A device measured it at the start and at the end. The number comes from the machine, not from how people felt.
The internist scored it in a medical interview, from 0 (none) to 4 (extremely severe).
Participants answered a questionnaire after 90 days. This is how they felt, not a lab measurement.
How the study worked
33 people started. All saw the internist on day 0, and 27 of them were also measured with devices. Everyone took one spoon a day for 90 days, then the same checks were repeated.
Day 0
Check-in
33 healthy adults. The internist interviews each one. 27 of them also have their skin and hair measured with devices.
Days 1–90
One spoon every morning
0.3–0.4 g in warm water before breakfast. Everyone keeps a daily diary of any reactions.
Day 90
Check-out
The 30 who finished see the internist again and fill in a questionnaire. 23 are measured again with the same devices.

The report
J.S. Hamilton writes up the results. A project manager, a data analyst, a quality auditor and the internist sign it.
Results · measured by devices
Two machines, used on day 0 and day 90. 23 people have both measurements. These numbers come from the machines, not from how people felt.
How many hairs there are in one square centimetre of scalp.
more hairs per cm² on average
23 of 23 people had more hairs per cm² on day 90.
How it was measured: the Aramo ASW 300F scalp camera magnifies a small area 60 times, and the result is given as hairs per cm².
How well skin springs back, and how firm it is.
improved on elasticity, and 22 of 23 on firmness
How it was measured: the Cutometer uses gentle suction. R0 is how far the skin stretches (lower is firmer). R2 is how much of that stretch it recovers (higher is more elastic).
| Measure | n | Day 0 mean (SD) | Day 90 mean (SD) | Change | Median | Range | Improved |
|---|---|---|---|---|---|---|---|
| Hair density (hairs/cm²) | 23 | 135.9 (26.6) | 148.3 (26.3) | +12.5 (+9%) | 126.7 → 143.3 | 103.3–198.3 → 116.7–213.3 | 23/23 |
| Skin elasticity R2 | 23 | 0.851 (0.056) | 0.885 (0.053) | +0.034 (+4%) | 0.875 → 0.910 | 0.758–0.934 → 0.747–0.946 | 22/23 |
| Skin firmness R0 | 23 | 0.344 (0.103) | 0.318 (0.095) | −0.026 (−8%) | 0.349 → 0.314 | 0.170–0.647 → 0.171–0.634 | 22/23 |
Report 978975-1/25/SLV/GDA/PK, section 6.4. 27 people entered the instrumental test; 4 (subjects 3, 11, 18 and 25) were excluded because their results could not be traced or they did not finish, so n = 23. SD of the change: hair 3.0, R2 0.029, R0 0.020. On each skin measure 22 of 23 people (96%) improved, but not the same 22: one person missed out on elasticity and a different one on firmness. For R2 the report counts subject 17 (0.934 → 0.935) as improved. The report gives only the direction of improvement for R0 and R2; the description above is how the Cutometer works. No significance tests were reported.
Results · scored by the internist
On day 0 and day 90 the internist asked about four symptoms and scored each from 0 (none) to 4 (extremely severe). Lower is better. The chart compares the same 30 people on both days.

Fatigue, digestive problems and slowed metabolism went down. General health issues stayed the same (0.27 on both days). Averages of the 30 people who finished.

|---|---|---|---|---|---|---|

Report section 6.2 and appendix 8.1. Table 3 counts all 33 people on day 0, including the 3 who later dropped out, and the 30 who finished on day 90. That is why general health issues appear to rise from 0.2 to 0.3 there; among the 30 who finished, the average was 0.27 on both days. The chart above uses those 30 people, recalculated from the individual scores in appendix 8.1. Columns show how many people had each score, day 0 → day 90. No one scored 4.
The general-health score rose for 5 people (subjects 13, 19, 27, 29, 32) and the fatigue score for 3 (subjects 19, 29, 33). Subject 14 had a severe (3) digestive score on day 90 while logging no reaction in the diary. The report does not assess whether any of this was caused by the product.

Report section 6.3, in the report’s order, n = 30. The 17 statements are the properties Mountaindrop asked the lab to test, all worded positively. Answers used a 4-point scale with no neutral option. We count the two favourable answers as agreement, which matches the report’s percentages (appendix 8.2); the report does not define it. Most agreement was a plain “yes”: “definitely yes” ranged from 3% to 23%. These are self-reported impressions, not measurements, and there was no placebo group.
The product and its safety
The questionnaire also asked about the product itself, in the report’s own words.
| Question, as printed in the report | Positive | People |
|---|---|---|
| “Suitable application.” | 90% | 27/30 |
| “Suitable appearance/functionality.” | 83% | 25/30 |
| “Overall assessment of the product.” | 70% | 21/30 |

| “Intention of buying the product.” | 50% | 15/30 |
| “Comparing with the product used in the past, the tested product was assessed as better.” | 43% | 13/30 |
Report section 6.3 and appendix 8.2, n = 30. On “better than the product used before”, 20% (6 people) had nothing to compare with and 33% rated it comparable. On intention to buy, 33% answered “don’t know”.
logged no reaction at all in their daily diary
6 people noted mild or moderate symptoms at some point, such as general health issues, fatigue or digestive problems. Two people took medication during the study, for headaches and sinusitis.
