The brow serum can be used daily and some customers find even better results using it 2x a day and have provided feedback like, "those of you who are not seeing results, please hang with it and use it on a regular basis". "Give it time, and how their patience and consistent adherence paid off". Also, we recommend applying the treatment from the inner brow to the outer brow but also the right outside hairline of the brow, massage it in for 1-2 minutes. The combination of the Botanical Brow Serum ingredients contributed to the success and results of the clinical trials and with our customers and with the main ingredients being Tea Tree, Lavender, Eucalyptus, Peppermint and Rosemary, along with the Biotin these 5 essential oils that are at a high percentage rate and would cause it to be more fragrant.

I hope this information is helpful and if we can help with any other questions please let us know.
