Thyroid issues can alter hormone levels and metabolic processes, potentially exacerbating skin oil production and inflammation, leading to acne. The results of this study indicate an association between the changes in the thyroid function, presence of antithyroid antibodies, and severity of acne in young patients. Assessing the thyroid antibodies in adult patients with acne should be considered by clinicians, because positive results lead to treating a higher number of subjects, as it is indicated by the current study outcomes.

https://pubmed.ncbi.nlm.nih.gov/21521376/ "There was a statistically significant difference (P = 0.008) in the prevalence of positive anti-TG antibodies, with 25.2% of the acne group and 8.3% of the control group having elevated (> 40 U/mL) anti-TG levels, respectively. Adult women with acne had a statistically significant increased relative risk to have high levels of anti-TG in comparison with healthy controls (odds ratio 3.89, P = 0.011). This association was independent of age. Values for TSH, FT4, FT3, T4 and anti-TPO did not significantly differ between the two groups. No significant difference was found regarding the thyroid ultrasound findings. Although there was no significant difference between cases and controls regarding CRP levels, it is interesting that we observed a significant elevation in CRP in those acne patients who had positive antithyroglobulin antibodies."

"A positive association was observed between the severity of acne and insulin resistance syndrome, obesity, autoimmune thyroiditis, and hypothyroidism (p < 0.05). Risk analysis indicated a significantly higher risk (RR > 1, 95% CI RR > 1, p < 0.001) of developing moderate and severe acne in the presence of these preconditions" Bungau, Alexa Florina et al. “Exploring the Metabolic and Endocrine Preconditioning Associated with Thyroid Disorders: Risk Assessment and Association with Acne Severity.” International journal of molecular sciences vol. 25,2 721. 5 Jan. 2024, doi:10.3390/ijms25020721 (edited)

No relationship between thyroid functions and postadolescent acne

"Cigarette smoking was significantly associated with postadolescent acne (P < 0.001). No significant differences were observed between patients with postadolescent acne and control subjects in triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels, thyroid hormone profiles, and thyroid ultrasound scans. High-density lipoprotein cholesterol levels were significantly decreased with postadolescent acne (P = 0.01)" Ekiz, Ozlem et al. “Assessment of thyroid function and lipid profile in patients with postadolescent acne in a Mediterranean population from Turkey.” International journal of dermatology vol. 54,12 (2015): 1376-81. doi:10.1111/ijd.12547 (edited)
