Raspberry ketone and your skin
Lipolysis, skin lightening, cellulite
Raspberry ketone, (also known as frambinone, rheosmin and 4-(4-Hydroxyphenyl)butan-2-one) stimulates fat release, inhibits fat accumulation, fights fat tissue inflammation and inhibits melanogenesis.
RASPBERRY KETONE CREAM
For the above reasons, raspberry ketone is an important active ingredient in anti-cellulite, leg wellness, contouring, skin brightening and under-eye creams [the Celluence® cellulite creams are the only creams in the world with 95% pure raspberry ketone, plus 39 other highly concetrated natural anti-cellulite actives].
6 ways RASPBERRY KETONE
helps boost lipolysis and fight fat accumulation and cellulite
Raspberry ketone can reduce body fat and cellulite, by boosting norepinephrine induced lipolysis
Raspberry ketone (also known as frambinone and rheosmin) is an aromatic compound found all red raspberries (Rubus idaeus) which is extensively used in perfumery. It's chemical structure is similar to that of zingerone, a ginger extract which reduces obesity. It is also similar to that of capsaicin (the chemical that gives hot chili peppers their "burning" quality), to synephrine (a substance found in orange peel and known to help reduce fat and fluid retention) and evodiamine (another fat loss ingredient). All these chemicals, including raspberry ketone, interact with fat cells and induce fat loss via similar mechanisms.
In 2004 a group of Japanese researchers examined the anti-obesity action of raspberry ketone in mice. To test the effect on obesity, the researchers fed mice in one experiment a high-fat diet including 0.5, 1, or 2% of raspberry ketone for 10 weeks. In another experiment mice were given a high-fat diet for 6 weeks and then fed the same high-fat diet containing 1% of raspberry ketone for the next 5 weeks.
After 11 weeks the results were rather amazing. Raspberry ketone did indeed prevent the high-fat-diet-induced fat gain in the first experiment, and decreased the fat accumulation produced by 6 weeks of high fat diet in the second experiment. In addition, raspberry ketone decreased the amounts of fat accumulated in the liver caused by the high fat diet, thereby improving fatty liver. The researchers concluded that this obesity preventing and reducing effect was due to the potentiation of the norepinephrine-induced lipolysis (i.e. fat breakdown) in fat cells.
Norepinephrine is produced by the body when we exercise, therefore the best time to consume raspberries or apply a raspberry ketone-rich cellulite cream on areas with excess fat, is immediately before and/or after exercise. This is when the raspberry ketone can really perform it’s magic.
In addition to raspberry ketone, raspberries and other berry fruits contain several other substances that help prevent and improve various health conditions, as well as overweight, cellulite, skin looseness and fluid retention, and are one of the most healthful foods you can eat. They offer lots of fibre and antioxidants and very few calories, making them very "dense" nutritionally.
You may literally consume as many fresh berries as you wish without fearing weight gain. In fact by doing so you will lose weight, because you will eat less of the calorie-dense foods that lead to fat accumulation and stop you from losing weight. The same principle applies to green vegetables, with the only difference that green vegetables are even better than berries as they contain almost no calories at all.
In addition to eating lots of berry fruits you may use raspberry ketone in a different way: by applying it on your skin in the form of a raspberry ketone-rich cellulite cream, immediately before or after exercise when noradrenaline (a.k.a. norepinephrine) levels are high.
However, you should know that food must not be eaten up to three hours before exercise as the anti-lipolytic effect of insulin will negate any benefits raspberry ketone and exercise have to offer. Food consumption immediately after one hour or more of vigorous exercise is absolutely fine and will not reduce the results of either exercise or raspberry ketone.
Source: Anti-obese action of raspberry ketone
Excerpt: "Raspberry ketone (4-(4-hydroxyphenyl) butan-2-one; RK) is a major aromatic compound of red raspberry (Rubus idaeus). The structure of RK is similar to the structures of capsaicin and synephrine, compounds known to exert anti-obese actions and alter the lipid metabolism. The present study was performed to clarify whether RK helps prevent obesity and activate lipid metabolism in rodents. To test the effect on obesity, our group designed the following in vivo experiments: 1) mice were fed a high-fat diet including 0.5, 1, or 2% of RK for 10 weeks; 2) mice were given a high-fat diet for 6 weeks and subsequently fed the same high-fat diet containing1% RK for the next 5 weeks. RK prevented the high-fat-diet-induced elevations in body weight and the weights of the liver and visceral adipose tissues (epididymal, retroperitoneal, and mesenteric). RK also decreased these weights and hepatic triacylglycerol content after they had been increased by a high-fat diet. RK significantly increased norepinephrine-induced lipolysis associated with the translocation of hormone-sensitive lipase from the cytosol to lipid droplets in rat epididymal fat cells. In conclusion, RK prevents and improves obesity and fatty liver. These effects appear to stem from the action of RK in altering the lipid metabolism, or more specifically, in increasing norepinephrine-induced lipolysis in white adipocytes."
Raspberry ketone suppresses fat accumulation and boosts lipolysis, by inhibiting PPAR-gamma and boosting ATGL and HSL, respectively
- Raspberry extract raspberry ketone (also known as rheosmin and frambinone) has been in the news for years regarding it's fat reduction benefits. The positive news was based around scientific studies which proved and explained it's potential in fighting fat and obesity, while the negative news revolved around exaggerated claims made by fraudulent practitioners and supplement manufacturers which hyped-up raspberry ketone benefits beyond all reason.
- Regardless of the hype and exaggeration though, the fact remains that raspberry ketone does have an effect on fat cells and more and more studies come to prove this.
- In a research paper published yesterday, raspberry ketone was shown to "suppress adipocyte differentiation and fat accumulation in a concentration-dependent manner and to suppress the expression of major genes involved in the adipogenesis pathway including peroxisome proliferator-activated receptor-γ (PPARγ) and CCAAT enhancer binding protein-α (C/EBPα)".
- This in plain English means that raspberry ketone blocks key proteins involved in fat cell growth and halts the growth and maturation of new fat cells (contrary to the urban myth, we constantly produce new fat cells to replace "dying" ones).
- Furthermore, "in mature adipocytes" raspberry ketone was shown to "increase the transcriptional activities of genes involved in lipolysis and the oxidative pathways including adipose triglyceride lipase (ATGL), hormone sensitive lipase (HSL), and carnitine palmitoyl transferase-1B (CPT1B)."
- Again, in plain English, this means that raspberry ketone stimulates fat cells to release fat out of the cell, which can then be taken into the general circulation for oxidation ("fat burning") in the muscles and other organs.
- So, in summary, raspberry ketone "attacks" adipose (fat) cells in two ways:
- It does not allow new, "baby" fat cells to grow and become fully functional, mature fat cells and stops them from accumulating fat
- It encourages fully grown, mature fat cells to actually release fat. When a fat cell releases all it's fat content it undergoes "apoptosis" or "programmed cell death" and dies off.
- The combination of growth inhibition in new fat cells and fat release and apoptosis in existing fat cells amounts to what most people simply call "breaking down the fat"!
- The authors of the study conclude that "these findings suggest that raspberry ketone holds great promise for an herbal medicine with the biological activities altering the lipid metabolism in 3T3-L1 adipocytes."
- And we could add to that, that if applied locally as an anti-cellulite cream active ingredient, raspberry ketone also holds great promise in the fight against localised adiposity and cellulite.

- Abstract: "Context: Raspberry ketone (RK) is a natural phenolic compound of red raspberry. The dietary intake of RK has been reported to exert anti-obese actions and alter the lipid metabolism in vivo and human studies. Objective: To elucidate a possible mechanism for anti-obese actions of RK, the effects of RK on the adipogenic and lipogenic gene expression in 3T3-L1 adipocytes were investigated. Materials and methods: 3T3-L1 maturing pre-adipocytes were treated from day 2 to day 8 of differentiation and mature adipocytes for 24 h on day 12 with 1, 10, 20, and 50 μM of RK. Triacylglycerols were assessed by spectrophotometry and gene expression by quantitative real-time polymerase chain reaction (qRT-PCR). Results: Treatment of adipocytes with RK suppressed adipocyte differentiation and fat accumulation in a concentration-dependent manner. RK suppressed the expression of major genes involved in the adipogenesis pathway including peroxisome proliferator-activated receptor-γ (PPARγ) and CCAAT enhancer binding protein-α (C/EBPα), which led to further down-regulation of adipocyte fatty acid-binding protein-2 (aP2). In addition, treatment with 10 μM of RK also reduced mRNA levels of lipogenic genes such as acetyl-CoA carboxylase-1 (ACC1), fatty acid synthase (FASN), and stearoyl-CoA desaturase-1 (SCD1). In mature adipocytes, RK increased the transcriptional activities of genes involved in lipolysis and the oxidative pathways including adipose triglyceride lipase (ATGL), hormone sensitive lipase (HSL), and carnitine palmitoyl transferase-1B (CPT1B). Discussion and conclusion: These findings suggest that RK holds great promise for an herbal medicine with the biological activities altering the lipid metabolism in 3T3-L1 adipocytes."
