Assessment built for the skin the clinic actually sees.
A skin-of-colour clinic gets diagnostic consistency from an engine trained on deeper tones first.



The context
25PSKYN consults and formulates for skin of colour, where most mainstream analysis tools quietly underperform. For a clinic whose whole premise is deeper skin, an engine that reads lighter tones better is not a small gap, it is the gap.
The challenge
Consultation-led skincare lives or dies on accurate assessment, and most mainstream tools underperform on deeper skin tones. For a clinic formulating for skin of colour, that gap is the whole problem.
What they did with Oyster
25PSKYN uses Oyster to read each client before the consult, on an engine built for the tones the industry has skipped, with skin tone read on the 10-point Monk Skin Tone Scale.
“Consultations start from a consistent, objective read of the skin, so product and treatment matching rests on measurement rather than the eye of whoever is on that day.”
The outcome
Consultations start from a consistent, objective read of the skin, so product and treatment matching rests on measurement rather than the eye of whoever is on that day.
