Overview of the Skin ID Profile
The Skin ID is a comprehensive private blood test designed to investigate internal biological factors that may be relevant to skin health, appearance and ageing. Rather than focusing only on the surface of the skin, the profile reviews hormones, nutritional status, inflammation, blood sugar regulation, thyroid function, fatty acids and major organ-function markers within one assessment.
The profile contains 42 listed biomarkers and laboratory profiles, including a Full Blood Count, HbA1c, hs-CRP, liver and kidney markers, Cortisol, thyroid hormones, reproductive and androgen-related hormones, a detailed iron profile, Vitamin D, Active B12, Folate, Magnesium, Zinc and an advanced fatty-acid assessment.
Skin symptoms are complex and rarely explained by one blood marker. Acne, dryness, changes in pigmentation, hair or skin quality, poor healing and premature skin ageing can have dermatological, hormonal, nutritional, inflammatory, environmental and genetic causes. The Skin ID is therefore designed to provide additional laboratory context rather than diagnose the cause of a skin condition by itself.
What Does the Skin ID Profile Contain?
This test measures 42 biomarkers and laboratory profiles across blood health, metabolic health, kidney and liver function, thyroid function, hormonal health, iron status, vitamins, minerals, inflammation and fatty-acid balance.
FBC - Full Blood Count assesses major red blood cell, white blood cell and platelet measurements, providing information relevant to anaemia, immune activity and general blood health.
HbA1c - Reflects average blood glucose exposure over approximately the previous two to three months and provides information about longer-term blood sugar regulation.
Glucose - Measures the concentration of glucose circulating in the blood at the time of collection and provides information about current blood sugar levels.
High Sensitivity C-Reactive Protein (hs-CRP) - Measures low concentrations of C-reactive protein and provides information about systemic inflammatory activity. It is non-specific and can be temporarily affected by infection, injury, exercise and other factors.
Sodium - Measures a major electrolyte involved in fluid balance, nerve signalling and normal cellular function.
Potassium - Measures an electrolyte essential for normal muscle contraction, nerve function and heart rhythm.
Urea - Measures a waste product formed during protein metabolism and provides information relevant to kidney function and hydration.
Creatinine - Measures a waste product produced during normal muscle metabolism and is commonly used when assessing kidney filtration.
Total Protein - Measures the combined concentration of major proteins circulating in the blood.
Albumin - Measures the main protein produced by the liver and provides information relevant to liver function, nutritional status and fluid balance.
Globulin - Measures a group of proteins involved in immune function, transport and several other physiological processes.
Total Bilirubin - Measures bilirubin produced during normal red blood cell breakdown and processed by the liver.
Alkaline Phosphatase - Measures an enzyme found particularly in the liver, bile ducts and bone.
ALT (GPT) - Measures alanine aminotransferase, an enzyme found predominantly in the liver and commonly used when assessing liver cell health.
AST (GOT) - Measures aspartate aminotransferase, an enzyme found in the liver, muscles and other tissues.
Gamma GT - Measures an enzyme associated mainly with liver and biliary function.
Cortisol - Measures cortisol, a hormone produced by the adrenal glands that is involved in the stress response, metabolism, blood pressure regulation and immune function.
Thyroid Stimulating Hormone (TSH) - Measures the pituitary hormone responsible for regulating thyroid hormone production.
Free T3 - Measures free triiodothyronine, the biologically active thyroid hormone involved in metabolism, temperature regulation and energy use.
Free Thyroxine (FT4) - Measures free thyroxine, the principal circulating thyroid hormone produced by the thyroid gland and available to body tissues.
Oestradiol - Measures a major form of oestrogen involved in reproductive health, bone health and other hormone-dependent physiological processes.
Follicle Stimulating Hormone (FSH) - Measures a pituitary hormone involved in ovarian function in women and sperm production in men.
Luteinising Hormone (LH) - Measures a pituitary hormone involved in ovulation in women and testosterone production in men.
Testosterone - Measures circulating testosterone as reported by the laboratory and provides information relevant to androgen status.
Prolactin - Measures a pituitary hormone involved in reproductive and hormonal regulation.
Free Androgen Index (FAI) - Provides a calculated estimate of androgen availability using testosterone and Sex Hormone Binding Globulin.
Free Testosterone - Assesses testosterone available to tissues rather than testosterone that is tightly bound to circulating proteins.
Sex Hormone Binding Globulin (SHBG) - Measures a transport protein that binds testosterone and oestradiol and influences how much hormone remains biologically available.
Serum Iron - Measures the amount of iron circulating in the bloodstream at the time of testing.
Ferritin - Measures the body's principal iron-storage protein and provides information about iron reserves. Ferritin may also rise during inflammation.
Iron Binding Capacity (TIBC) - Measures the blood's capacity to bind and transport iron.
Transferrin - Measures the main protein responsible for transporting iron through the bloodstream.
Transferrin Saturation - Measures the proportion of transferrin binding sites occupied by iron and provides additional information about iron availability.
Magnesium - Measures an essential mineral involved in energy metabolism, muscle contraction, nerve signalling and numerous enzyme reactions.
Zinc - Measures an essential trace mineral involved in immune function, wound healing, protein synthesis and many enzyme pathways.
Serum Folate (Vitamin B9) - Measures circulating Folate, which is important for DNA synthesis, cell division and normal red blood cell production.
Active B12 - Measures the biologically available fraction of Vitamin B12 and provides information relevant to B12 status, nervous system function and blood-cell production.
Vitamin D (25-OH) - Measures 25-hydroxyvitamin D, the principal blood marker used to assess Vitamin D status.
Omega 3 Index - Measures the proportion of selected omega-3 fatty acids within red blood cell membranes and provides information about longer-term omega-3 status.
Omega-6:Omega-3 Ratio - Compares selected omega-6 and omega-3 fatty acids and provides additional information about overall fatty-acid balance.
Omega Trans Fat Index - Measures selected trans fatty acids within the fatty-acid profile and provides information about longer-term dietary fatty-acid exposure.
Omega AA:EPA - Compares arachidonic acid with eicosapentaenoic acid and provides additional information about the balance of these fatty acids.
Who May Benefit From the Skin ID Profile?
This test may be suitable for people who want to investigate nutritional, hormonal, metabolic and inflammatory factors that may be relevant to persistent skin concerns or general skin health.
Investigate persistent acne or breakouts - Androgen-related hormones, Oestradiol, Prolactin, glucose regulation and inflammation may provide useful laboratory context.
Review dry, dull or changing skin quality - Vitamin D, Zinc, Active B12, Folate, iron status and fatty-acid markers may be useful to assess alongside other possible causes.

Symptoms and Reasons to Consider the Skin ID Profile
You may wish to consider the Skin ID if you have persistent skin concerns and want to investigate internal factors that could provide useful additional information alongside dermatological assessment.
Persistent or recurring acne - Androgen-related hormones, glucose regulation and inflammatory markers may provide useful context, although acne has many possible causes.
Hormonal breakouts - Testosterone, Free Testosterone, SHBG, FAI, Oestradiol, LH, FSH and Prolactin may be relevant where a hormonal contribution is suspected.
Dry or persistently dull skin - Nutritional, thyroid and fatty-acid markers may provide useful information alongside environmental and dermatological factors.
Slow wound healing - Zinc, glucose regulation, iron status and general blood health may be relevant to review.
Hair thinning alongside skin changes - Iron status, thyroid hormones, Vitamin D, Zinc and androgen-related markers may provide useful additional information.
Changes in skin quality around menstruation, perimenopause or menopause - Reproductive hormone results may provide context when interpreted according to age, symptoms and cycle stage.
Persistent redness or inflammatory skin concerns - hs-CRP provides information about systemic inflammation, although it does not identify the cause of a specific skin condition.
Changes in pigmentation or complexion - Nutritional, hormonal and metabolic factors may sometimes warrant investigation, but pigmentation changes should also be assessed clinically where appropriate.
Premature changes in skin appearance - Fatty acids, nutrition, metabolic health and hormonal factors can be reviewed as part of a broader assessment of health and ageing.
Wanting a comprehensive internal skin-health baseline - The Skin ID provides a broad set of laboratory results that can be compared over time.
Skin conditions such as acne, eczema, rosacea, pigmentation disorders and dermatitis are not diagnosed through this blood profile. Many have causes that cannot be identified from blood testing alone, and persistent, severe or changing skin lesions should be assessed by a GP or dermatologist.
The purpose of the Skin ID is to identify laboratory patterns that may provide useful context. A nutrient level outside the reference range does not automatically explain a skin symptom, and a normal profile does not exclude dermatological disease.
How to Prepare
If reproductive hormone assessment is an important reason for testing, record the first day of your most recent menstrual period and your current cycle day where relevant. Do not stop prescribed hormonal or thyroid treatment unless specifically advised by your clinician.

Receive your results securely
Your results are sent securely by email, ready to review yourself or discuss with a GP, dermatologist, endocrinologist or other suitably qualified clinician.
When Will I Receive My Results?
The expected turnaround time for the Skin ID is approximately 1 week.
Results are sent securely by email once laboratory analysis and authorisation are complete. Turnaround generally begins when the laboratory receives your sample rather than necessarily from the time your blood is collected.
The Skin ID includes specialist fatty-acid measurements, which may take longer than routine blood markers. Additional laboratory processing, quality checks or repeat analysis can occasionally extend the expected turnaround.
Understanding Your Results
Your Skin ID report will provide individual results together with the relevant reference ranges or reporting criteria used by the analysing laboratory. Reference ranges can vary according to laboratory method, age, sex and other clinical circumstances.
Related markers are generally more useful when interpreted together. Testosterone should be considered alongside Free Testosterone, SHBG and FAI, iron should be reviewed alongside Ferritin, TIBC, Transferrin and Transferrin Saturation, and thyroid results should be considered as a pattern across TSH, FT3 and FT4.
The fatty-acid measurements provide information about omega-3, omega-6 and selected trans-fatty-acid status. They should be interpreted in the context of diet, supplementation, medical history and overall cardiovascular and metabolic health rather than being treated as direct measurements of skin ageing.
A normal laboratory result does not rule out a skin condition, while an abnormal result does not prove that the biomarker is responsible for a particular skin symptom. If you have persistent acne, rashes, changing moles, unexplained pigmentation, non-healing lesions or other concerning skin changes, seek appropriate clinical assessment.
