28 days of mask care: publishing our complete record of skin changes

We present ExoMask Pro’s hydration, wrinkle, elasticity and other results together with the study’s population and limits.

We used a human evaluation conducted by SGS to record AgeCare ExoMask Pro’s performance over 28 days of continued use. Thirty-two healthy Chinese women with sensitive skin, aged 31–60, used it twice weekly for at least 45 minutes each time. Results were compared with their own pre-use measurements. We publish hydration, wrinkle, elasticity and other records together to present this mask’s continued-use evaluation.

How the 28 days were organized

Participants used the currently sold ExoMask Pro finished product: one freeze-dried bio-sheet plus three accompanying beauty solutions. The study used a single-group before-and-after comparison. The main analysis included 32 participants, with a separate exploratory imaging subgroup of seven described below.

We distinguish study frequency from everyday instructions. The study used twice-weekly application. Routine use is recommended once a week; intensive care is limited to twice a week, at least three days apart, with 45 minutes of application each time.

Hydration and principal wrinkle measures

At day 28, stratum corneum hydration increased by 27.62% and transepidermal water loss (TEWL) decreased by 20.05%. Wrinkle volume at the outer eye, between the eyebrows and at the nasolabial fold decreased by 25.64%, 22.68% and 19.09% respectively.

Day-28 measure Change from before use
Stratum corneum hydration Increased by 27.62%
Transepidermal water loss (TEWL) Decreased by 20.05%
Outer-eye wrinkle volume Decreased by 25.64%
Glabellar wrinkle volume Decreased by 22.68%
Nasolabial-fold wrinkle volume Decreased by 19.09%

Elasticity, firmness and skin appearance

Elasticity measures R2, R5 and R7 increased by 14.33%, 19.47% and 21.04%. The firmness-related F4 measure decreased by 18.80%, indicating improvement in the direction used for this measure. Gloss, redness, pore and skin-surface records are below; all compare day 28 with pre-use values.

Day-28 measure Change from before use
Elasticity R2 Increased by 14.33%
Elasticity R5 Increased by 19.47%
Elasticity R7 Increased by 21.04%
Firmness-related F4 Decreased by 18.80%
Skin gloss Increased by 40.72%
Red-area a value Decreased by 14.73%
Red-area extent Decreased by 27.45%
Pore count Decreased by 23.12%
Pore volume Decreased by 19.62%
Pore area Decreased by 16.88%
Roughness SEr Improved by 25.48%
Smoothness SEsm Improved by 19.00%
MGL Decreased by 13.84%
Ultrasound skin thickness Increased by 16.11%
Ultrasound skin density Increased by 14.26%

Ultrasound thickness and density record changes in those measurements. These results did not independently establish mechanisms such as collagen production. We retain the original measure names to keep the data aligned with what was observed.

Complete wrinkle results by location

We also publish counts, depth, length and area. Locations are listed separately, retaining the comparison between day 28 and each participant’s own pre-use baseline.

Location Measure Change
Outer eye Count Decreased by 12.21%
Outer eye Depth Decreased by 10.55%
Outer eye Length Decreased by 9.72%
Outer eye Area Decreased by 18.18%
Outer eye Volume Decreased by 25.64%
Between eyebrows Count Decreased by 14.29%
Between eyebrows Depth Decreased by 9.55%
Between eyebrows Length Decreased by 10.69%
Between eyebrows Area Decreased by 17.33%
Between eyebrows Volume Decreased by 22.68%
Nasolabial fold Depth Decreased by 8.14%
Nasolabial fold Length Decreased by 7.83%
Nasolabial fold Area Decreased by 13.51%
Nasolabial fold Volume Decreased by 19.09%
Forehead lines, static Count Decreased by 11.93%
Forehead lines, static Area Decreased by 12.47%
Forehead lines, dynamic Count Decreased by 11.02%
Forehead lines, dynamic Area Decreased by 13.52%

Exploratory imaging subgroup of seven

Beyond the main analysis of 32 participants, the evaluation recorded two-photon imaging measures in seven participants. The following changes were not supported by statistical significance and are presented separately as exploratory observations.

Day-28 exploratory measure, N = 7 Change from before use
Two-photon epidermal thickness Increased by 7.28%
SAAID Increased by 56.61%
ELCOR Decreased by 3.24%

The experiences reported by 32 participants

In the day-28 questionnaire, agreement was 100% for each of “overall satisfaction”, “willingness to continue use” and “willingness to recommend”. These are subjective responses from this group and are recorded separately from instrument measurements.

We disclose the complete results while retaining the evaluation’s limits: a single-group before-and-after study has no separate control group, so these data alone cannot isolate the influence of factors other than the care routine. Individual performance may differ.

Hydration, wrinkles, elasticity, exploratory observations and user experiences together form this 28-day record. They provide specific evidence for our continuing presentation of ExoMask Pro’s performance.
