How does PromoCell determine the phototype of skin tissue donors?

PromoCell uses a classification system similar to, but not identical with, the Fitzpatrick Skin Classification.

The Fitzpatrick classification distinguishes six phototypes (I–VI) based on skin pigmentation (melanin content) and the skin’s response to sun exposure:

• Phototype I: Very fair skin, always burns, never tans
• Phototype II: Fair skin, burns easily, tans poorly
• Phototype III: Medium skin, tans after initial burn
• Phototype IV: Light brown skin, rarely burns, tans easily
• Phototype V: Brown skin, very rarely burns, tans darkly
• Phototype VI: Dark brown or black skin, never burns

PromoCell donor classification:
For PromoCell skin tissue donors, information is available on:

• Skin color (white, brown, or black)
• Eye color
• Hair color

However, no information is available on individual tanning or burning behavior.
Therefore, PromoCell classifies donors into the following three phototype groups:

• Light (corresponding to Fitzpatrick phototypes I and II)
• Moderate (corresponding to Fitzpatrick phototypes III and IV)
• Dark (corresponding to Fitzpatrick phototypes V and VI)

Information on the phototype group is available for most cell lots derived from juvenile or adult skin tissue. Our Scientific Support team can assist in the selection of suitable cell lots based on the desired donor phototype.
