Frequently Asked Questions

How does The iuno SkinDetect Test work?

Our SkinDetect Test assesses protein, hormone, and antibody levels to identify abnormal inflammation that could be preventing you from achieving clear, radiant, and healthy skin. 

We look at dozens of blood proteins that are mapped to dryness, aging, redness and discoloration. We then use this information to model skin health scores for skin barrier strength, skin firmness, skin function and your proteomic age (a measure of your body’s biological age, which may differ from your chronological age) Our team is constantly working to improve our skin model. In the nearest future we’re looking to add skin scores for collagen, hyperpigmentation and skin type.
