Avoid certain products: Do not use brow growth serums, castor oil, or any self-tanners for 48 hours before your appointment. Avoid chemical exfoliants like AHAs or glycolic acid for at least 72 hours.

Stay out of the sun: Avoid sunburn and excessive sun exposure to your face for about 4 weeks before the treatment.

Exfoliate: Gently exfoliate the brow area 48 hours before your appointment. Be sure to not over-do this as it can make the skin more sensitive if done too aggressively.
