What is cellulite?

TL;DR: In cellulite, abnormally enlarged ‘fat pouches” push skin upwards. At the same time abnormally short and hard ‘collagen bands’ anchor the skin surface down to the deeper tissues more strongly than normal.

The combination of one upward force (‘fat pouches’) and one downward force (‘collagen bands’) makes fat pouches protrude upwards of the anchor skin around them. This results in the familiar mattress appearance of cellulite, also described as cottage cheese or orange peel skin (peau d ‘orange).

What is cellulite: the ultimate guide to cellulite anatomy and physiology

There is ridiculous misinformation on cellulite in the media. Instagram, blogs, newspapers, glossy magazines, clinic/salons, cellulite equipment manufacturers and cellulite cream manufacturers offer such gems as “cellulite is toxins”, “cellulite is just fat”, “cellulite does not exist”, “cellulite is natural”, “cellulite is normal”, “cellulite is just fascia”, “cellulite is just water retention”, “90% of women in the world have cellulite” etc etc.

For the vast majority of people the perceived wisdom on the nature of cellulite is based on urban myths such as the above and is a mixture of confusion, ignorance, half-knowledge and misinformation.

With so much misinformation around cellulite, it is no wonder why most cellulite treatments are so ineffective: we cannot correct a problem if we are ignorant or misinformed about the problem’s nature.

And with so much confusion, one would think that there exists no research on the nature (anatomy and physiology) of cellulite and that it is all made up stuff. However, this could not be further from the truth.

There is plenty of quality research on the anatomy and physiology of cellulite and its causes, based on ultrasound, MRI, microscopy and biochemistry investigations, and this and two more articles (“Pre-cellulite: the origins of cellulite” and “Is cellulite normal?”) are all about presenting those facts.

Furthermore, this entire website is dedicated to providing information on cellulite and its treatment and skin tightening.

Cellulite: anatomy & physiology 

Cellulite is enlargement of adipose tissue compartments at the dermis and hypodermis level, i.e. the medium and deep skin layers, respectively.

This adipose tissue compartment enlargement is almost always accompanied by:

  • Laxity at the dermis level

  • Inflammation and oedema (water retention) at the hypodermis level

  • Shortening and fibrosis of the retinaculae cutis (aka skin ligaments or “collagen bands”)

In cellulite:

  • Abnormally enlarged ‘fat pouches” push skin upwards

  • At the same time abnormally short and hard ‘collagen bands’ anchor the skin surface down to the deeper tissues more strongly than normal.

  • The combination of one upward force (‘fat pouches’) and one downward force (‘collagen bands’) makes fat pouches protrude upwards of the anchor skin around them. This results in the familiar mattress appearance of cellulite, also described as cottage cheese or orange peel skin (peau d ‘orange).

Scientific cellulite definition I

The best scientific definition of cellulite which describes it (almost) accurately is: "Oedematous FibroSclerotic DermoPannicullopathy (OFSDP)". This in plain English translates as: inflammation of the skin’s fat deposits, accompanied by scar tissue and inflammation / water retention.

The above includes all the hallmarks of cellulite in one elegant, four-word definition:

  • OEDEMA (water retention)

  • FIBROSIS-SCLEROSIS (scar tissue / hardening of connective tissue)

  • SKIN FAT (dermo-pannicullus)

  • INFLAMMATION (-opathy)

As SKIN LAXITY is found in 90% of cellulite cases, we should add the word “flaccid”, in which case we have: Flaccid Oedematous FibroSclerotic DermoPannicullopathy (FOFSDP).

We could perhaps also add the word toxic to the above definition, as the creation of cellulite is significantly accelerated  by the accumulation of fat soluble toxins in adipose tissue.

So a revised, all-inclusive definition of cellulite could be: "Toxic Flaccid Oedematous FibroSclerotic DermoPanniculitis" (TFOFSDP).

But then the name becomes too long - plus the acronym is not that pretty, so I don’t expect it to catch any time soon, although being very accurate and descriptive…

Scientific cellulite definition II

Another scientific definition of cellulite is: “DermoPanniculosis Deformans”. This basically means:

  • Inflammation of the skin’s fat tissue (dermopanniculosis)

  • Accompanied by deformity / fibrosis (deformans)

Not very comprehensive and still too much Latin…

Cellulite explained

To start explaining how cellulite develops, it is worth noting that fat in the deeper layers of the skin is always enclosed in little compartments wrapped up by a thin sheath of connective tissue, forming "fat pouches".

(Connective tissue is tissue made of a network of collagen, elastin and other proteins. Connective tissue is what keeps everything together and gives shape to our body.)

These fat pouches are literally suspended by collagen strands (retinaculae, skin ligaments) that attach them:

  • To the surface of the skin above (dermis)

  • And to deeper tissues underneath (intermediate fascia)

This forms a three-dimensional suspension structure whose ‘tensegrity’ makes skin soft, but also firm and elastic at the same time.

These long, thick collagen strands (retinaculae) that run from the dermis above all the way to the intermediate fascia below are, together with the enlarged fat pouches, responsible for the mattress cellulite appearance.

Cellulite, connective tissue and adipose tissue

Connective tissue refers to collagen and elastin rich tissue that gives shape to our body and keeps it together: ligaments, tendons, fascia, sheaths, skin ligaments/retinaculae, skin/dermis and it is also a constituent of muscles, bones, blood vessels and organs.

As such, connective tissue is an important aspect of cellulite.

What most people do not know, however, is that adipose tissue is a subtype of connective tissue, which is rich in fat. And adipose tissue is the most important aspect of cellulite.

As adipose tissue forms part of connective, we can say the cellulite is a connective tissue aesthetic condition.

Fat pouch peaks and collagen strand troughs

Now, it is also worth noting that fat cells can swell up to 3,000 times their normal volume.

  • As these fat pockets enlarge with excess fat and water, they expand and push the skin surface upwards

  • On the other hand, in reaction to the pushing of fat outwards, the collagen strands that connect the surface of the skin above to the deeper tissues below, become overstretched and injured

  • This injury eventually leads to scarring, shortening and hardening (fibrosis) of the collagen strands, eventually culminating in the skin being pulled downwards at those points

Cellulite anatomy: the cellulite mattress appearance

The peaks (caused by fat pushing the skin out) and troughs (caused by skin ligaments pulling the skin down) cause the mattress appearance that we call cellulite.

If dermis (the main skin layer) is loose, it allows itself to be deformed more easily, and the mattress appearance becomes more pronounced.

In this picture:

• The sofa’s upholstery foam corresponds to fat

• The upholstery leather corresponds to the weakened dermis, the skin’s main layer

 • The upholstery button threads correspond to the collagen strands / skin ligaments / retinaculae

Cellulite’s downward spiral

  • There are hundreds of anti-cellulite creams around but 90% of those creams don't really work

  • 90% of beauty salons offer some sort of cellulite treatment

  • And 90% of those treatments fail to offer you anything more than a slight, temporary reduction of cellulite

And the obvious question is: why?

The answer to the "Why” question is the multi-faceted nature of cellulite.

In one small area of skin you can have connective tissue hardening (fibrotic retinaculae) yet at almost the same spot you also have skin looseness (lax dermis); AND water retention; AND inflammation; AND excessive fat accumulation.

And each of those things reinforce the other, in a perpetual vicious circle that gradually destroys the very fabric of the skin in the legs, buttocks and - quite often - stomach, waist and arms.

An analysis of this vicious circle follows.

Cellulite physiology: a web of complications - literally and metaphorically 

Remember how we described cellulite earlier as a three-dimensional web structure? Well, that was referring to a literal, physical web. However, the problem with cellulite is also another, metaphorical web: the web of complications.

Cellulite is characterised by a web of reinforcing feedback mechanisms:

  • Inflammation, as any biology student knows, leads to water retention and vice versa, in a perpetuating negative loop

  • Inflammation quite often leads to fibrosis / sclerosis (scar tissue / tissue hardening)

  • Water retention inhibits fat removal, but does not prevent fat accumulation ("fat trap" effect)

  • An excess of adenosine and alpha2 adrenoreceptors in the fat tissue, due to chronic exposure to oestrogen, also inhibits fat removal, but does not prevent fat accumulation ("fat trap" effect)

  • Every month the menstrual cycle is accompanied by the release of MMPs (matrix metalloproteinases), which break down collagen, thereby weakening the dermis

  • Ever expanding fat tissue (due to excess calorie / sugar consumption) further injures the connective tissue strands attached to it and causing more fibrosis / sclerosis

  • On the other hand, ever expanding fat tissue breaks down the connective tissue around it, causing skin looseness. Ever wondered why fat makes your skin flabby? That's why, fat eats into your skin.

  • Furthermore, ever expanding fat tissue mechanically inhibits circulation, causing more water retention

  • Water retention / poor circulation leads to adipose tissue hypoxia, which is well known to cause inflammation, oxidative damage, fibrosis and glycation (connective tissue protein damage due to sugar consumption). And vice versa - all reinforcing each other.

  • Toxins from food, alcohol, cigarettes/vaping, plastics/BPA/contraception accumulate in the fat tissue and cause further fat tissue inflammation, hypoxia and glycation

As you see, it just goes on and on and on.

One complication causes another, which causes another, which causes another, and the whole thing becomes a never ending vicious circle.

The vicious circle of cellulite must be broken at multiple points, if we want to make some real progress with cellulite reduction

Attempting to break this web at just one point, as in with a single ingredient cream or with a "fascia blasting massage" is naive, to say the least.

  • In addition reducing food intake is by itself not enough either, as evidence shows

  • And the same applies to "cellulite exercises" (hint: they don’t exist), as every woman knows

  • A bit of lymphatic drainage to (very temporarily) reduce water retention is clearly nowhere near enough

  • And let's not even talk about the pathetic joke of "dry skin brushing" 😂

  • Some caffeine cream to marginally boost fat removal and circulation will not do it either. Otherwise, with the amounts of coffee women drink today, there would be no such a thing as cellulite. Caffeine does help, but on its own is not even close enough to effectively remove cellulite.

  • And let's not even mention the sheer time-wasting ritual of rubbing ground coffee on thighs 😂

To reduce cellulite a comprehensive approach is needed

A good cellulite treatment should work on both skin laxity AND hypodermal fat reduction AND poor circulation AND fibrosis reduction:

  • The strongest, most effective, SAFE cellulite technologies currently are deep-acting, high-power radiofrequency and high-power ultrasound cavitation

  • There is no known technology that directly works on the other aspects of cellulite, i.e. inflammation, oxidative damage or glycation, but there are plenty of natural topical active ingredients which help in that direction

And the same applies to creams: a good cellulite cream must contain actives which are well established to work against many, if not all aspects of cellulite: fat AND poor circulation AND oxidative damage AND glycation AND fibrosis AND inflammation AND skin laxity:

  • The best anti-cellulite cream is one one with multiple, high-purity anti-cellulite actives in high concentrations

  • Well-researched such actives include caffeine, asiatic acid, asiaticoside, madecassic acid, madecassoside, forskolin, EGCG, escin, esculin, chlorogenic acid, hydroxyproline, cocoa flavanols and curcumin, among others

Furthermore, both treatments and creams have to be combined with healthy eating, vigorous exercise (sorry, relaxing Yoga and Pilates classes don't count) and sugar / smoke / alcohol / BPA / contraceptive pill avoidance, if some good results are to be expected and maintained.

This is how cellulite is reduced: by attacking it on all seven fronts.
