About the test
Experiencing skin concerns like acne or premature aging?
Estradiol (E12) is the strongest of the three naturally occurring estrogens. Although it is the primary female hormone, estradiol is found in all sexes. It contributes to healthy bone maintenance, improves blood flow in coronary arteries, offers neuroprotective effects, and helps both sexes maintain a healthy libido. Estradiol is also essential to skin function and health. It has been shown to improve elasticity, hydration, and thickness.
In women, progesterone is most commonly known for its role in maintaining regular menstrual cycles and early stages of pregnancy. In men, it is a precursor to testosterone. Progesterone can also play a role in skin health, stimulating sebum production. Too much progesterone can lead to oil buildup, while too little can trigger symptoms like acne.
Testosterone is often regarded as the male sex hormone, but it is essential for bone density, libido, body fat distribution, and supporting muscle mass across all sexes. Healthy testosterone levels can help the skin maintain optimal moisture and elasticity. Free testosterone refers to the testosterone that is not attached to proteins, while total testosterone includes free testosterone and testosterone bound to the proteins in the blood.
DHEA, or dehydroepiandrosterone, is an androgen hormone primarily produced by the adrenal glands. DHEA is a precursor hormone, meaning it has a little biological effect on its own. However, when it’s converted into other hormones like testosterone and estrogen, it has powerful effects. High levels of DHEA can lead to oily skin and acne. DHEA peaks in early adulthood and gradually decreases with age.
Cortisol is a steroid hormone produced in the adrenal glands and released in response to stressors like exercise and illness. While it’s often referred to as the “stress hormone,” cortisol has many other bodily functions, including blood sugar and metabolism regulation. Studies show that chronic stress may also negatively affect overall skin health and exacerbate skin conditions like psoriasis, rosacea, eczema, acne, and hair loss. In most people, cortisol levels are highest in the morning and lowest in the middle of the night.
Thyroid Stimulating Hormone (TSH)
Thyroid stimulating hormone, or TSH, is produced by the pituitary gland. It’s responsible for regulating hormones T3 and T4, which are produced by the thyroid gland. Low levels of TSH can lead to dry skin. TSH is considered the most sensitive marker for screening for thyroid diseases and conditions.
Vitamin D (25-OH D)
Vitamin D forms when your skin absorbs sunlight and is found in natural and fortified foods. It plays a role in various bodily processes, including bone formation and maintenance, as well as immune function. It may also contribute to skin health by reducing inflammation, decreasing environmental damage, and normalizing cell turnover. Low vitamin D intake over time may lead to a vitamin D deficiency.
