What is biotin?
Biotin, also known as vitamin B7, is a water-soluble B-complex vitamin that plays an important role in supporting the health of hair, skin, and nails. In medical aesthetics, biotin is commonly used as a supplement or injectable support vitamin to help improve overall hair and nail quality.
What is biotin used for in medical aesthetics?
Biotin may help to:
- Support healthy hair growth
- Improve hair strength and thickness
- Strengthen brittle or weak nails
- Support skin health and appearance
- Assist the body’s natural keratin production
Biotin is often used alongside other treatments for hair loss, hair thinning, and nail weakness.
How is biotin administered?
Depending on clinic protocols, biotin may be provided as:
- Oral supplements (tablets or capsules)
- Injectable biotin (often as part of a vitamin injection or hair-loss support programme)
Our Specialist Nurse Prescriber will advise on the most suitable option for you.
