Biotin, also known as vitamin B7, has gained popularity as a supplement for improving hair, skin, and nails. Many people take biotin hoping to boost their skin health, but some report unexpected side effects like acne breakouts. Understanding how biotin affects your skin can help you make informed decisions about using these supplements.

What Is Biotin and Why Do People Take It?
Biotin is a water-soluble vitamin that plays a key role in converting food into energy. It supports the health of hair, skin, and nails by aiding in the production of fatty acids and amino acids. Because of these benefits, biotin supplements have become common among those looking to improve their appearance.
People often take biotin to:
Strengthen brittle nails
Promote hair growth
Improve skin texture and hydration
While biotin is essential for overall health, most people get enough from a balanced diet. Foods rich in biotin include eggs, nuts, seeds, and certain vegetables.
How Biotin Might Affect Acne
Despite its benefits, biotin can sometimes cause or worsen acne in certain individuals. This happens because biotin interacts with other vitamins and hormones that influence skin health.
The Role of Vitamin B5 (Pantothenic Acid)
Biotin and vitamin B5 share a complex relationship. High doses of biotin may interfere with the absorption or function of vitamin B5, which is important for skin health. Vitamin B5 helps regulate oil production in the skin, and a deficiency can lead to increased sebum, clogging pores and causing acne.
Hormonal Effects
Biotin may also influence hormone levels that affect the skin. Some studies suggest that excessive biotin intake can increase the production of insulin-like growth factor 1 (IGF-1). Elevated IGF-1 levels are linked to increased oil production and inflammation, both of which contribute to acne development.
Individual Sensitivity
Not everyone reacts to biotin the same way. Some people can take high doses without any skin issues, while others may notice breakouts even with moderate supplementation. Factors like genetics, existing skin conditions, and overall diet play a role in how biotin affects your skin.
Signs That Biotin Could Be Causing Acne
If you recently started taking biotin supplements and notice new or worsening acne, consider these signs:
Breakouts appear mainly on the forehead, cheeks, or jawline
Acne develops shortly after beginning biotin supplementation
Skin feels oilier than usual
Other causes like diet changes or stress are ruled out
Tracking your skin’s response to biotin can help determine if the supplement is a trigger.
Managing Acne While Taking Biotin
If you want to continue taking biotin but are concerned about acne, try these strategies:
Adjust the dosage: Lowering your biotin intake may reduce skin issues while still providing benefits.
Balance with vitamin B5: Some people find taking vitamin B5 alongside biotin helps prevent breakouts. Consult a healthcare provider before combining supplements.
Maintain a skincare routine: Use gentle cleansers and non-comedogenic moisturizers to keep pores clear.
Monitor diet and lifestyle: Avoid foods that trigger acne and manage stress levels.
If acne persists or worsens, consider stopping biotin and consulting a dermatologist.
When to Seek Professional Advice
Persistent or severe acne should be evaluated by a healthcare professional. A dermatologist can help identify the root cause and recommend treatments tailored to your skin type. They may also advise on the safe use of supplements like biotin.
Final Thoughts on Biotin and Skin Health
Biotin supplements can support hair and nail health, but their impact on skin varies. Some people experience acne flare-ups due to biotin’s interaction with other vitamins and hormones. Paying attention to your skin’s response and adjusting your supplement routine can help you enjoy the benefits without unwanted side effects.
If you’re considering biotin for skin improvement, start with a low dose and watch for changes. Combining biotin with a balanced diet and proper skincare offers the best chance for healthy, clear skin.
