Israeli company creates cure for 5 o’clock shadow

Related tags: Shaving

Israeli ingredient company IBR has created an anti-ageing ingredient which promises to end the battle with the five o’clock shadow once and for all.

Named IBR Dormin, the additive was originally developed as an anti-ageing inhibitor, but a recent study has shown that it can also be used to cut down on the number of times that men with fast-growing hair need to shave.

Used in shaving foam, Dormin softens the skin and slows down the proliferation of cells. Unlike most facial hair inhibitors, it is available in organic and 100% natural forms.

Liki von Oppen-Bezalel, VP of marketing for IBR, commented to “The whole idea is a very unique anti-ageing concept.”

“As an anti-ageing ingredient IBR Dormin is well established on the market, but this new use for it shows that it’s a timeless product.”

The ingredient

IBR Dormin is derived from the bulbs of the narcissus plant, with two of the four versions of the product being taken entirely from natural ingredients.

It works by inhibiting cell proliferation, thus preventing them from multiplying and growing as quickly as normal.

There are structures on the inside of the narcissus called Dormins, which release chemicals to delay growth in the plants in the seasons when they are dormant.

By extracting these, IBR have created a natural inhibitor which can slow down both the appearance of ageing and the growth of hair.

Liki commented: “We thought that one of the problems some men have us that they can need to shave more than once per day.”

“The concept is to affect the biological clock which is built into the cell.”

“We thought, if you can slow down the growth of cells, you can also inhibit the growth of hair.” 


In a recent clinical study, IBR-Dormin was found to be successful in preventing hair growth in three quarters of those it was tested on.

The ingredient inhibited hair growth in 74% of subjects by an average of 13%.

The researchers calculated that on average this would delay the appearance of five o’clock shadow by around three and a half hours.
