Sebum · Oil Mapping

Measuring sebum to balance shine, breakouts and barrier

We quantify surface lipids (µg/cm²) at standard facial sites to understand your oil profile. It’s invaluable for acne-prone, combination and dehydrated-but-oily patterns.

What we measure

Using a sebum-specific probe/film, we capture sebum units (µg/cm²) at multiple standardised sites (T-zone, cheeks, chin, peri-oral). Readings reflect true lipid load and distribution — not just “looks shiny”.

How it works

After short skin equilibration, the sampling probe/film is applied with gentle pressure for a set time. The device/software quantifies surface lipids per cm². We average sites and log environmental context.

  • Pre-measurement cleanse standardised
  • Avoid occlusives/makeup before the session
  • Ambient temperature/humidity noted

What your reading means

Higher values indicate more surface lipids; very low readings can accompany dehydration or over-cleansing. Your map informs cleanser type, actives (retinoids, azelaic, salicylic), moisturiser weight and in-clinic cadence.

Notes: Measurements guide care and do not diagnose disease. We interpret sebum with hydration and TEWL for the full barrier picture.
