Bruleur Jour-Nuit – DéfiLigne

Brûleur Jour-NuitDéfiLigne Brûleur Jour-Nuit is a fat burning product sold under the Yves Rocher brand name.

The company also markets numerous health and beauty and personal care products, including a range of shower gels, skin hydration creams, shampoos, and antiperspirants.

Yves Rocher seems to have its fingers in lots of pies, so it’s questionable if it produces any of the products it distributes or merely buys them in from elsewhere.

After sales service is good though, and customer support representatives are available via phone (Monday to Friday, 8:00 to 20:00, and Saturday 08:00 to 19:00).

How Does Brûleur Jour-Nuit Work

Brûleur Jour-Nuit is a two-part weight loss supplement designed to be used for a period of 28 days. It consists of a red diet pill that is taken every morning and a white diet pill for the evenings.

Unfortunately, the sales page on the Yves Rocher website provides very little information about how the product is likely to deliver the intended fat burning effect. It only states the product contains green tea to “contribute to the degradation of fat” and has some ingredients to assist with normal energy metabolism.

What Is In DéfiLigne Brûleur Jour-Nuit

Both tablets contain a number of binders, fillers, and other non-active components, but the active ingredients are:

Daytime Formulation

Each tablet contains:

  • Green coffee bean extract (600mg)
  • Yerba mate (400mg)
  • Green tea (360mg)
  • Guarana seed extract (200mg)


Nighttime Formulation

Each tablet contains:

  • Artichoke juice extract(1200mg)
  • Citrus aurantium fruit extract (500mg)
  • Rosemary leaf extract (200mg)
  • Green tea (90mg)


The fact that both formulations contain green tea is good. It’s a proven fat burner that’s renowned for its health enhancing abilities, but it’s questionable if the amount included in the nighttime tablet is enough to deliver much benefit.

Green coffee bean extract is also a good fat burner and it further assists weight loss by controlling insulin levels and helping to prevent the blood sugar spikes that can sometimes lead to cravings for sweet food.

Yerba mate and guarana provide caffeine. It’s good for fat burning, but it’s a stimulant as well, so it’s sensible that it is not included in the nighttime formulation. It’s presence there would have the potential to interfere with sleep.

The nighttime formulation has citrus aurantium though. Research gives its fat burning reputation credibility but, like caffeine, it’s a stimulant that’s capable of causing sleepless nights. The value of rosemary is debatable, but it’s reputed to assist weight loss.

Artichoke is a better inclusion because it helps detoxify the body and get rid of the toxins that build up over time and can slow the metabolism enough to make gaining weight easier than losing it.

How to Use Brûleur Jour-Nuit

One red daytime tablet is required each morning with breakfast and should be taken with water. One white nighttime tablet needs to be taken during the evening meal and washed down with water. Brûleur Jour-Nuit is intended to be used in conjunction with a calorie controlled diet and regular exercise.

Although the product is not designed for continuous use, it’s permissible to repeat the 28-day treatment a few times throughout the year.

DéfiLigne Customer Comments

A few customer comments read:

“I lost 23 pounds while I was using Brûleur Jour-Nuit, but you need to eat healthy and get plenty of exercise. My sister thought she could lose weight just be taking the pills. She didn’t lose more than a couple of pounds. “ 

“I wasted my money on this product. It doesn’t work. I weighed about the same at the end of the treatment.” 

“I was losing around 1kg a week while I was using this day and night system, but I don’t kid myself. I was eating right and exercising hard and I know that was a big part of it.” 

“I’ve always been very impressed with this company’s beauty products, but weight loss doesn’t appear to be their forte. These pills didn’t help me at all. I’m still tubby and hating it.”

Side Effects & Health Considerations

Brûleur Jour-Nuit is not recommended for women who are pregnant or nursing a child. People who have existing health issues should always seek a doctor’s advice before using supplements of any kind. The same is true for people who are using medication.

Where to Buy DéfiLigne Brûleur Jour-Nuit
