In the privacy of the lab, experts juggle stability, viscosity and formula compatibility. Yet once the product is in the end user’s hands, real life can hold surprises. One of the most frustrating phenomena for a consumer is the appearance of small balls after application: pilling.
To shed light on the subject, SYRES ran a large survey of 2,300 consumers. The results show that this technical detail is far from anecdotal.
Pilling is not an isolated incident
According to our study, 62.4% of consumers say they have already observed pilling after applying a cosmetic product. For most it remains occasional, but some users experience it regularly. Pilling occurs mainly in the morning, at the crucial moment of the skincare routine.
The data show two major triggers:
- Physical contact: 47.8% of cases occur simply when rubbing or touching the skin.
- Layering: 41.4% of respondents see pilling appear when applying a second product over the first.
The most affected areas of the face are the cheeks (53.3%) and the forehead (34.7%). Some products are pointed at more often, such as moisturisers (48.6%), foundations (24.6%) and serums (23.9%), but the product alone is rarely the only culprit.
An interaction phenomenon
The determining factors cited by consumers are:
- layering several products (52.2%);
- incompatibility between certain formulas (31.7%);
- textures that are too rich or thick (14.8%).
More than an aesthetic annoyance
Pilling profoundly influences brand perception and purchasing behaviour. The average level of annoyance is 6.5 out of 10. The psychological and commercial impact is concrete: 64% of users say it can affect their self-confidence during the day, and nearly half (48.9%) say the problem directly influences their future product choices.
For formulators and brands, understanding these usage mechanisms is essential. A formula’s performance does not stop at its stability in a test tube; it plays out every morning in consumers’ bathrooms. At SYRES we analyse these complex interactions through sensory studies and consumer tests, to make sure technological innovation translates into genuine satisfaction on the skin.
