Acne, the bane of many adolescents and adults alike, can be a stubborn and perplexing condition to tackle. From over-the-counter creams to prescription medications, individuals often try a plethora of treatments in hopes of achieving clear, blemish-free skin. However, what if the solution to this dermatological dilemma lies not in topical remedies but in a simple blood test?
Acne vulgaris: Commonly occurring in teenagers and young adults, typically between 9-30 years of age, acne vulgaris is often a part of pubertal changes. Generally, a blood test is not required for this type of acne.
Hormonal acne and adult acne: Hormonal acne, which can affect any age group, and adult acne (acne tarda), which starts after the age of 30, often require further investigation. For these types, specific tests to measure hormone levels, including female and male hormones, androgens, insulin resistance, and thyroid function, can be crucial. These tests help dermatologists identify the root cause of hormonal imbalances and guide further management.
Vitamin D deficiency: There is an independent association between low vitamin D levels and acne. Testing for vitamin D levels can be an important step in addressing persistent acne issues.
The decision of when and which tests to perform is dependent on the clinical discretion and judgment of the treating dermatologist; a one-size-fits-all approach does not work in these cases. By tailoring the tests to the individual, dermatologists can better understand the underlying causes of acne and provide more effective treatment options.
