What it is and why it's in the formula
Lavender oil (Lavandula angustifolia) is one of the most widely recognized calming botanicals by scent alone, and it's a common finishing note in spray-format cosmetic products. It's named directly in the product's essential-oil sensitivity notice, so it's one of the oils worth patch testing for if you have any history of fragrance or essential-oil sensitivity.
Patch test first: Lavender Oil is a genuine essential oil named in PureNail Pro's essential-oil sensitivity notice. Apply a small amount to a small area of skin and wait 24 hours before your first full application. Discontinue use and consult a doctor if irritation, redness, or discomfort develops.
Where it fits in the full formula
Lavender Oil is one of 16 ingredients disclosed openly on the PureNail Pro label — none of the formula sits behind vague "proprietary blend" wording. You can see the complete breakdown, including which oils pair with it, on the full ingredients page.
