The Opti Laboratories Brow Growth Treatment contains a 0.3 mg/ml (0.03%) solution of bimatoprost, a prostaglandin analogue, the exact same as Latisse.

The solution was originally used as an eye drop to treat Glaucoma, a condition affecting the pressure within the eyeball. It was used successfully by millions of patients over a prolonged period. A well documented side effect of the treatment was eyelash growth. The active ingredient, bimatoprost, has since been found to stimulate the hair growth cycle, resulting in hair that is longer, thicker and darker. It is equally effective when used on the brows.

In 2008, the American FDA gave approval for the cosmetic use of bimatoprost. The FDA drew on years of data to compile a safety profile of the treatment. They found that there were significantly fewer side effects when applied to the skin rather than to the eyeball itself. This may be due to the reduced dose, as it’s a smaller area, and because the skin is less sensitive than the eye itself.

The results were also documented; it was found that the average trial participant grew hairs that were 25% longer, 106% thicker and 18% darker. 

The treatment is effective on the lashes and brows, where it can transform the think vellus hairs of your face into thick hairs like those of your eyebrow.
