Some online articles say Biotin causes acne breakouts? Is that true?

The theory that biotin causes breakouts is based on taking biotin supplements alone, resulting in depletion of vitamin B5. The skinB5™ vitamins formulations actually contain a high potency dosage of vitamin B5, supported synergistically by other vitamin Bs, like B3 (nicotinamide), folic acid and biotin.  The inclusion of biotin in the skinB5™ vitamins actually boost your skin, hair and nail health. When you take skinB5™ vitamins not only your skin clears up, you will notice your hair grows thicker and nails become stronger!
