What is the Skin ID Test?

The Skin ID Blood Test Panel is an advanced diagnostic test designed to evaluate the internal biological factors that influence skin health, ageing, hydration, inflammation and overall skin quality. While skincare products target the surface, many skin concerns originate internally, making blood testing essential for a deeper understanding of skin function.

This panel analyses multiple systems that directly impact skin condition, including hormonal balance, inflammation, nutritional status, fatty acid composition, metabolic health and organ function. By identifying imbalances in these systems, the test helps explain common skin concerns such as acne, dryness, premature ageing, pigmentation and poor healing.

Skin health is closely linked to internal physiology. Factors such as hormone fluctuations, nutrient deficiencies, inflammation and oxidative stress can all affect collagen production, sebum levels, hydration and skin barrier integrity. The Skin ID Panel provides a comprehensive overview of these factors, allowing for personalised skincare, nutrition and treatment strategies.

Why do I need a Skin ID test?

Many skin concerns are not purely cosmetic but are influenced by internal health. Hormonal imbalance, inflammation, nutrient deficiencies and metabolic dysfunction can all contribute to skin issues such as acne, dryness, premature ageing and sensitivity.

The Skin ID Panel helps identify the root causes of skin concerns rather than just treating symptoms.

This test is particularly useful for individuals experiencing:

• Acne or hormonal breakouts
• Oily or excessively dry skin
• Premature ageing or fine lines
• Pigmentation or uneven skin tone
• Skin inflammation or redness
• Poor wound healing
• Hair thinning or skin dullness
• Hormonal imbalance symptoms
• Chronic stress affecting skin quality
• Persistent skin conditions not responding to treatment

For example:

• Elevated androgens may increase oil production and acne
• Low Vitamin D or zinc may impair skin repair
• High inflammation markers may accelerate ageing
• Imbalanced fatty acids may affect skin hydration and barrier function

Understanding these internal drivers allows for targeted, personalised treatment strategies.

Benefits of the Skin ID Panel

1. Identifies root causes of skin issues
Rather than treating symptoms, the test identifies internal imbalances affecting skin health.

2. Supports acne and hormonal skin analysis
Hormone markers help evaluate causes of breakouts and oil production.

3. Evaluates ageing and collagen factors
Inflammation, nutrients and hormones influence skin ageing and elasticity.

4. Assesses nutritional deficiencies
Vitamin and mineral levels affect skin repair, hydration and glow.

5. Monitors inflammation levels
Chronic inflammation can accelerate skin ageing and sensitivity.

6. Analyses fatty acid balance
Omega-3 and Omega-6 balance plays a key role in skin hydration and barrier function.

7. Supports personalised skincare strategies
Results help tailor skincare, supplementation and treatments.

8. Provides a holistic skin health overview
Combines multiple systems for a complete internal skin assessment.

Step by Step

We offer two convenient ways to take this test anywhere in the UK.

Option 1 – Visit a Clinic

• Choose your nearest UK clinic
• Attend your appointment
• A healthcare professional collects your blood sample
• Samples are sent to the laboratory
• Results are delivered securely

Option 2 – Home or Hotel Visit

For £60 extra, a phlebotomist can visit you.

• Book online
• A phlebotomist travels to your home, office or hotel
• Your sample is collected safely
• No need to travel

Both services are available UK-wide.

Your Results Explained

Low Levels

Low levels may indicate nutrient deficiencies, hormonal imbalance or reduced skin repair capacity.

Examples include:

• Vitamin D: low levels may affect skin regeneration and immunity
• Zinc: deficiency may impair healing and increase acne risk
• Oestradiol: low levels may affect skin hydration and elasticity
• Omega-3: low levels may reduce skin barrier function

Symptoms may include dry skin, dull complexion, poor healing and increased sensitivity.

Normal Levels

Balanced biomarkers support healthy skin function.

Typical UK ranges include:

• Vitamin D: 50–125 nmol/L
• CRP: below 3 mg/L
• TSH: 0.4 – 4.0 mIU/L

These levels support hydration, collagen production and balanced skin physiology.

High Levels

Elevated biomarkers may indicate inflammation, hormonal imbalance or metabolic stress.

Examples include:

• Testosterone: elevated levels may contribute to acne
• CRP: high levels indicate inflammation affecting skin ageing
• Omega-6 imbalance: may promote inflammatory skin conditions
• Liver markers: elevated levels may affect detoxification and skin clarity

Further evaluation can guide targeted treatment strategies.
