ESSENTIAL NUTRIENT
What is Biotin?
Also known as Vitamin B7, biotin is a 
water-soluble B vitamin that plays a 
crucial role in multiple metabolic 
processes throughout your body.
As a coenzyme, biotin facilitates fatty 
acid synthesis, amino acid metabolism, 
and energy production—supporting 
overall cellular health far beyond its 
well-known benefits for skin, hair, and 
nails.

How Biotin Supports Skin Integrity
Cellular Foundation
Keratinocytes—the primary cells that make 
up your skin—depend on biotin for proper 
function and renewal. These specialized cells 
continuously regenerate, creating the 
protective layers that shield your body.
Environmental Defense
Biotin strengthens your skin's protective 
outer layer, helping defend against 
environmental stressors like pollution, UV 
radiation, and harsh weather conditions.

Together, these mechanisms contribute to a 
clear, resilient complexion with improved 
texture and tone.
Biotin Deficiency and Skin 
Manifestations
Skin Symptoms
Though rare, biotin deficiency can manifest as dry, scaly rashes, seborrheic 
dermatitis, and various forms of skin inflammation that affect appearance 
and comfort.
Associated Effects
Beyond skin issues, deficiency commonly presents with brittle nails that 
crack easily, hair thinning, and in severe cases, alopecia or hair loss.
Root Causes
Deficiency is typically linked to malnutrition, prolonged antibiotic use, 
certain medications that interfere with absorption, or rare genetic disorders 
affecting biotin metabolism.

cardiac markers and thyroid function tests. Always consult healthcare providers 
before supplementing.
