Advanced Eyelash Growth Serum Clinical Study

Clinical study on Dr. Speron's Natural Skin Care’s Advanced Eyelash Growth Serum overviews patient feedback, measurements, and photographs used throughout the duration of the clinical study. In the pages to follow, observation of the growth, lengthening, and density of lashes is displayed.


As eyelash characteristics are very similar to those of scalp hair, Dr. Speron's Natural Skin Care’s Advanced Eyelash Growth Serum represents the ideal and perfect solution to modulate eyelash growth in order to avoid eyelash loss and stimulate biological mechanisms behind eyelash growth.

Compared with human hair, little is known about eyelashes. In the embryo, eyelashes develop between the 7th and 8th week. They grow in imperfect rows of five to six in the upper and three to four in the lower lid.

Their mean number is 90-160 in the upper and 75-80 in the lower lid, while their length varies from 8 to 12 mm in the upper and from 6 to 8 mm in the lower lid. The terminal eyelash fiber is characterized by a regular curve shape, more or less marked depending on ethnic origin. Microscopy of eyelash revealed a structure very close to that of hair fiber, with three compartments from the outside to the inside. However, the eyelash fiber is much shorter than scalp hair, due to a shorter hair cycle.

The growth rate is approximately 120 µm daily and the duration of anagen and telogen phases is estimated to be 1-4 and 4-9 months respectively. At any given time, 59-85% of eyelash follicles are in the telogen phase, depending on whether upper or lower lid.

OBJECTIVES

The aim of the study was to evaluate the efficacy of Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum under normal conditions of use. Relevancy Cosmetic products present effects on ciliary characteristics, which are shown through biometrological measurements and subjective evaluations. These observations were performed under normal conditions of use.

STUDY DESIGN

Design: The study was open and randomized. The treated eye on which Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum was applied was randomized. The average age of the subjects was: 49.4 ± 14.4 years old (extreme values: 25 - 68 years old). 17 subjects were included according to the following criteria:

CONDITIONS OF USE (APPLICATION)

Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum was applied on the upper and lower lashes of the eye designed by the randomization, in the morning, before the application of the usual mascara and a second time, alone, in the evening, during 8 weeks. 2 steps application of Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum - twice a day (morning and evening) for 8 weeks:

Application of Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum to skin using applicator. Draw the applicator carefully along the skin at the base of the upper and lower eyelashes (where the eyelashes meet the skin).

Application of Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum on lashes using the brush as close to the roots of your lashes as possible and wiggle before brushing out to get more product applied to every lash. Lightly brush the tip back and forth across lower lashes.


RESULTS

Evaluation of lash density

Lash density was measured after 4 and 8 weeks for each volunteers; results showed here after presented the average of lash density evolution of all the volunteers.

We observed a clear and significant evolution of lash density when eyelashes were treated with Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum.

  • The lash density is increased up to 27% after 8 weeks application of Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum.
  • It is important to note that after 4 weeks, 73% of the subjects improved in lash density and 93% had an effect after 8 weeks.
  • The improvement in lash density also indicated that Dr. Speron Natural Skin Care’s Advanced Eyelash Growth Serum treatment induced an increase in new lashes and decrease in falling lashes.
