Case study / Beauty Home Use Test
A lightening night cream, tested for 30 days in Singapore homes.
One monadic home use test gave the client three things at once: a launch decision, a claim file, and the texture story its marketing team ran with. Here is how it ran and what came back.
- Method
- Monadic quantitative home use test
- Sample
- n = 54 volunteers
- Profile
- Asian, 18 to 60, varied skin types, pigmentation concerns
- Duration
- 30 days
- Application
- Face, neckline, hands, nightly
- Measure
- Online self-completion questionnaire, before and after
The brief
Three questions before a launch.
The client was preparing to bring a lightening night cream to the Singapore market and needed to know, with consumers rather than in a lab, whether it delivered on its promise.
- Efficacy: does it visibly reduce dark spots, and does skin feel more hydrated and even?
- Cosmetic qualities: is the texture, absorption and scent accepted in a hot, humid climate?
- Tolerance: what discomfort or intolerance appears over a month of nightly use?
Behind the three questions sat one decision: launch as is, adjust first, or hold.
What came back
Visible efficacy in 30 days, a texture people loved, and a tolerance profile that cleared the launch.
Efficacy
- Dark spots less visible at D30
- 78%
- Skin tone more even
- 81%
- Skin better hydrated
- 85%
- Efficacy rating
- 7.9/10
Perceived results on face, neckline and hands after 30 nights, with the first improvements reported at the D14 check-in. Strong enough to document as claims.
Cosmetic qualities
- Pleasant to apply
- 96%
- Fast absorption
- 93%
- Liked the scent
- 89%
- Comfortable in humidity
- 90%
The non-greasy, lightweight texture was the product's clearest asset in Singapore conditions, and became the lead message of the launch.
Tolerance
- No discomfort at all
- 91%
- Mild tingling, week 1 only
- 9%
- Withdrawals
- 0
A transient tingling on five volunteers, gone by the D14 check-in and traced to one skin profile. Very good tolerance for a lightening formula, and a clear go for launch.
Reading the numbers
Alone, 87% is a good score. Against the category, it is a top-quartile launch.
A satisfaction figure means nothing without a reference. Read against our Singapore database, the client could see this cream sat in the top quarter of comparable night creams on texture and perceived efficacy. Its tolerance was compared with 19,000 tolerance results recorded on the market: above the category average.
