The Serum That Holds a Mask in Place

What the founder wanted

A founder imagined a daily barrier serum that would hold a facial mask in place for the first minute, then disappear without pilling, tack or humidity reactivation.

How it was built

I developed the formula direction from scratch by turning “grippy, then gone” into a timed sequence the chemist could test. I compared thickening and film-forming routes, set limits for tack and humidity response, and planned the order of experiments for sampling.

What was included

• A second-by-second texture target
• Polymer, humectant and thickener route comparison
• Humidity, pilling and layering experiments
• Supplier, cost and revision priorities

What it unlocked

A strange but memorable sensory idea became a clear development programme: enough grip to do the job, then no trace left behind.
