Labs To Run On Teenagers with Persistent Acne

Persistent acne can significantly impact teenagers, affecting their self-esteem, social interactions, and overall well-being. Acne often appears in common areas like the forehead, cheeks, chin, and back due to overactive oil glands and hormonal changes. Left untreated, persistent acne can lead to scarring, both physically and emotionally.

While many teens turn to topical treatments, these may not always be enough to address the root causes of acne. That’s where lab tests become important in acne management. This article explores common labs that can help guide acne management for teenagers.

Hormonal Panel Testing

Hormonal imbalances significantly impact persistent acne in teenagers, especially during puberty when hormone levels fluctuate significantly. These hormonal shifts can lead to increased oil production in the skin, which clogs pores and causes breakouts. For many teens, this type of acne, known as hormonal acne, is most commonly seen on the chin, jawline, and lower face. 

Understanding a teen’s hormone levels through hormonal panel testing can help doctors create more personalized treatment plans to target the root causes of persistent acne.

Tests to consider:

• Testosterone: Testosterone is a hormone that stimulates the skin’s oil glands, causing an increase in sebum (oil) production. High testosterone levels are often linked to acne, particularly in areas like the chin and jawline, which are common spots for hormonal acne in teenagers.
• Dehydroepiandrosterone sulfate (DHEA-S): Produced by the adrenal glands, DHEA-S helps generate androgens, increasing oil production. High levels of DHEA-S may contribute to breakouts in the lower face, especially in the chin and jawline area.
• Estrogen and Progesterone: These hormones help regulate the menstrual cycle in girls, and imbalances can lead to acne flare-ups, particularly around menstruation. Hormonal acne in girls often appears on the chin and jawline, areas commonly affected by hormone fluctuations.
• Luteinizing Hormone/Follicle-Stimulating Hormone (LH/FSH): LH/FSH control reproductive processes, and an imbalance can influence the production of other hormones, potentially worsening acne. Testing LH and FSH can help determine if reproductive hormone imbalances are playing a role in acne development.

Thyroid Function Panel

Thyroid dysfunction, especially hypothyroidism (underactive), can be an underlying cause of persistent acne. The thyroid gland controls various bodily functions, including metabolism and skin health. Hypothyroidism can slow down skin cell turnover, leading to clogged pores and acne breakouts.  Early detection of thyroid dysfunction can help address these skin issues more effectively.

To identify thyroid issues, several key tests should be considered. 

• Thyroid-stimulating hormone (TSH)—TSH measures how much the pituitary gland is signaling the thyroid to produce hormones. High levels of TSH may indicate an underactive thyroid. 
• Free T4 and Free T3 tests - Free T4 and T3 tests—Free T4 and T3 tests assess the levels of active thyroid hormones in the bloodstream. Low levels of these hormones can signal hypothyroidism. 
• Thyroid Antibodies - Thyroid antibodies, such as Thyroid Peroxidase Antibodies and Thyroglobulin Antibodies, helps determine if an autoimmune disorder, like Hashimoto's thyroiditis, is contributing to the problem.

Androgen Levels Testing

Androgens significantly impact the development of acne, particularly during adolescence. Elevated androgen levels, common in both teenage boys and girls, can overstimulate the oil glands in the skin. This leads to an overproduction of sebum (oil), which can clog hair follicles and result in acne. Androgens also influence hair follicle growth, which can further contribute to the development of acne lesions.

Two key tests are recommended to assess androgen levels: 

• Free and Total Testosterone - Testosterone is the primary androgen, and it can exist in two forms in the blood—free testosterone, which is unbound and active, and total testosterone, which includes both free and bound testosterone. Measuring both gives a complete picture of the hormone's activity. 
• Androstenedione - This is another important androgen that serves as a precursor to both testosterone and estrogen. Elevated levels of androstenedione can also contribute to excessive oil production and the onset of acne.

When androgens are elevated, oil glands work overtime, leading to clogged pores, inflammation, and acne breakouts. Identifying high androgen levels can help healthcare providers tailor treatment strategies more effectively. Anti-androgen therapy, such as using medications like spironolactone, may be recommended for girls to reduce androgen activity and decrease acne flare-ups.

Vitamin D Levels

A deficiency in vitamin D has been linked to increased acne severity. Vitamin D is critical in regulating the immune system and supporting skin health. When Vitamin D levels are low, the body’s ability to manage inflammation diminishes, which can result in more severe acne.

The Serum 25(OH)D (Vitamin D) test is the most commonly recommended test to evaluate vitamin D levels. This blood test measures the amount of Vitamin D circulating in the body and helps to assess whether the levels are within a healthy range.

Optimizing Vitamin D levels can directly impact skin health. Vitamin D helps control the immune response and reduces the risk of excessive inflammation, both of which are key factors in acne formation. If a deficiency is identified, increasing Vitamin D through supplements or lifestyle changes, such as spending more time in the sun or incorporating Vitamin D-rich foods, may help improve acne symptoms.

Inflammatory Markers

Chronic inflammation is often a contributor to persistent acne. While acne is commonly considered a surface-level skin issue, underlying systemic inflammation can drive breakouts and make them more difficult to treat. Inflammation causes the immune system to overreact, developing red, swollen pimples that are slow to heal.

Two blood tests can help assess if systemic inflammation is contributing to acne: 

• C-Reactive Protein (CRP)—The CRP test measures levels of C-reactive protein, a marker of inflammation that rises when the body is experiencing an inflammatory response. 
• Erythrocyte Sedimentation Rate (ESR) - ESR assesses how quickly red blood cells settle at the bottom of a test tube; a faster rate indicates higher levels of inflammation.

These inflammation markers provide insight into whether an underlying condition contributes to acne. By identifying elevated CRP or ESR levels, healthcare providers can determine if chronic inflammation is at the root of the issue.

Addressing inflammation can improve skin health. Treatment strategies might include anti-inflammatory diets rich in whole foods and antioxidants or medical interventions such as medications that target inflammation. By reducing overall inflammation, acne can improve, and general health may benefit as well, leading to clearer skin and fewer breakouts. 

Gut Health and Microbiome Testing

The gut-skin connection is becoming an increasingly recognized factor in understanding and managing acne, particularly persistent cases. Imbalances in gut health, including conditions like dysbiosis (an imbalance in gut bacteria) and Small Intestinal Bacterial Overgrowth (SIBO), can lead to systemic inflammation, which may trigger acne flare-ups. When the gut microbiome is disrupted, harmful bacteria can proliferate, releasing toxins that affect digestion and skin health.

To assess gut health in relation to acne, two important tests can be considered: 

• Comprehensive Stool Analysis - This evaluates the composition of gut bacteria, detecting imbalances, infections, or inflammatory markers that could be contributing to skin problems. 
• SIBO Breath Test - The SIBO breath test measures hydrogen and methane levels in the breath after consuming a specific sugar solution. It helps to identify bacterial overgrowth in the small intestine, a condition that has been linked to digestive issues and acne.

Understanding gut health is essential because addressing imbalances often leads to improvements in skin condition. When gut dysbiosis or SIBO is treated through probiotics, diet changes, or targeted medical treatments, systemic inflammation can decrease, which often results in clearer skin and fewer acne breakouts.
