After several recommendations I decided to purchase Chanel's eyebrow kit, Le Sourcil De Chanel. This was a deviation from my standard eyebrow pencil, as the kit comes with three powders that can be blended to achieve the perfect colour and thickness depending on individual preferences.
The Chanel eyebrow kit includes a set of (very good) tweezers, a brush to tidy the brows and a brush to properly apply the product.
I was slightly concerned that the product may not be ideal for day-to-day use due to the application process, however I've since found it takes no longer than a standard pencil. Additionally, it allows the opportunity to change the look of your brows depending on the look you're trying to achieve.
One of the other key benefits of the Chanel eyebrow kit is that it literally lasts all day due to the highly concentrated mineral pigments within the powder - that is definitely a bonus.
The Le Sourcil De Chanel kit cost me £43 however based on the amount of product required per application I can imagine it will be a long time before I need to replace this!
