Use twice daily: once in the morning & once in the evening on clean, dry skin (remove all makeup before use). Coat the brow & lash roots with a single stroke of growth serum & watch how the hairs are transformed. The formula works by prolonging the anagen growth phase of the hair growth cycle & shortening the transition period from the resting to growth phases. 100% of participants in BBL's study found an improvement in their lashes after 4 weeks, but consistency & patience are key. It can take up to 3 months to see results. We recommend discontinuing the use of the growth serum for 24 hours after a lash lift or brow lamination; 24 hours will not affect the progress of growth. The BB Lash & Brow Boost will not damage the eye in any way & it will not dissolve eye fat. Growth serums containing prostaglandin analogues have been linked to lost eye fat - creating a sunken, hollow effect - but this product does not contain this ingredient - or any hormones - and is 100% safe to use.
