Ferritin, Iron, Transferrin & Transferrin Saturation
Iron is essential for normal cellular and tissue function. Iron deficiency can affect the skin and other rapidly renewing tissues, and low iron stores can be present before iron-deficiency anaemia develops.
Ferritin provides information about the body's stored iron, while serum iron, transferrin and transferrin saturation help assess circulating iron and its availability. Looking at these markers together provides a more complete picture of iron status than serum iron alone.

Skin Function & Barrier
Vitamin D has biological functions within the skin. Skin cells can produce and respond to active vitamin D, which is involved in keratinocyte differentiation, epidermal barrier formation and immune function.
Measuring 25-OH vitamin D provides an assessment of your vitamin D status and can identify deficiency or insufficiency.

Skin Renewal & Repair
Zinc is an essential micronutrient involved in numerous cellular processes, including cell proliferation, immune function and tissue repair. Zinc deficiency can affect skin integrity and is associated with impaired wound healing.
Measuring zinc can help identify whether zinc status may be inadequate.

Essential Fats & Skin Barrier
Essential fatty acids are part of normal skin biology and contribute to the lipid environment needed for healthy skin-barrier function. A fatty acid profile provides information about key fatty acids, including omega-3 and omega-6, and can help show whether dietary intake or supplementation is reflected in blood fatty-acid levels.
Clinical research has also investigated the relationship between omega-3 status and skin characteristics. In randomized placebo-controlled pilot studies, krill-oil supplementation increased the Omega-3 Index and was accompanied by improvements in transepidermal water loss, skin hydration and elasticity. Changes in the Omega-3 Index correlated with changes in these skin measurements.
A fatty acid profile, however, is not a direct measurement of skin hydration, elasticity or skin-barrier quality.

Blood Health & Nutritional Context
A complete blood count measures haemoglobin, red blood cells and other blood-cell parameters. Haemoglobin is responsible for carrying oxygen to tissues throughout the body.
In this check, the Complete Blood Count is particularly useful alongside the iron markers: it helps determine whether depleted iron stores are accompanied by changes consistent with anaemia and provides broader context when interpreting iron and nutritional status.
Rather than being a specific "skin test", it helps complete the picture of the internal nutritional factors being assessed.

Real ratings and reviews from the Healsens app on the App Store and Google Play.
That's when I turned to a nutritionist and ordered a blood test through Healsens. … Four months later, I retested. My biological age dropped to 24—nearly a decade younger than my real age.
Read on App Store →It helps me track main parameters, understanding what do they mean and correlations, and make critical analysis to make preventative changes. Hope too see new fichas soon!
Read on App Store →Everything is great! Excellent app! It's very convenient for storing all your test results! The only thing I wish was that you could record blood pressure readings for both arms, as this is sometimes important for blood pressure monitoring.
Read on Google Play →A useful app. It motivates me to lead a healthy lifestyle and monitor my diet. After the test results, I decided to change my diet – I cut out flour and chocolate. I lost 2 kg in about a week. We'll see how the test results look over time.
