Learn what is the dermal hypodermal junction (DHDJ) and how it is related to cellulite
The Dermal HypoDermal Junction (DHDJ) is the border between the collagen-rich dermis (medium-depth skin layer) above and much fattier and less collagenous hypodermis (deepest skin layer) underneath.
In people without cellulite, the DHDJ is a pretty straight line, denoting no fat infiltration from the hypodermis to the dermis that causes the familiar cellulite bumps
In people with cellulite, the DHDJ has a more “bumpy” appearance, which is caused by fat infiltrating into the dermis, thereby resulting in the cellulite ‘peak and trough’ appearance
So the shorter the length of the DHDJ, the better.
(Sometimes, the DHDJ is erroneously called '“Dermal SubCutaneous Junction". However, the next layer after the dermis is the hypodermis, not the subcutaneous adipose tissue, which is found even lower. This mistake arises from the erroneous idea that the hypodermis and the subcutaneous fat is one and the same - which it ISN’T. And of course, this is different to the Dermal Epidermal Junction (DEJ), which is a more superficial anatomical site.)
So is DHDJ length the way to measure cellulite?
Not totally. DHDJ length indicates superficial cellulite. Below ‘superficial cellulite’ lies ‘deep cellulite’, which can be less or more pronounced than superficial cellulite.
But generally speaking, the dermal hypodermal junction is an important focus.
How to shorten the length of the DHDJ and thereby reduce your clients’ cellulite
You need to:
Strengthen the dermis, so it does not get deformed by fat infiltration from the hypodermis below. This can happen with a skin tightening method, the best of which is deep-acting, high-power radiofrequency, properly focused to act on the dermis
Reduce fat accumulation in the hypodermis, so it does not infiltrate into the dermis. This can happen best with either deep-acting, high-power ultrasound cavitation, again focused to act on the hypodermis and/or deep-acting, high-power radiofrequency, also focused to act on the hypodermis.
Of course, everyone is different and in some cases you need to focus on one aspect more than the other or use one technology more than the other.
And naturally, the client must follow a healthy nutrition and exercise regime, to help build collagen and stop fat accumulation from the inside.
In the last two decades I have done extensive research, combined with practical application with thousands of sessions and can now specifically pinpoint our work on the dermis, DHDJ, hypodermis or subcutaneous adipose tissue.
Now you can get instant access to this expertise and save yourself literally thousands of $$$/£££ of expensive mistakes and thousands of hours of study, research and practical application by attending one of our 1-day or 2-day or 3-day professional consultancy / training courses.
Understand radiofrequency, ultrasound cavitation, phototherapy, cellulite and skin tightening deeply and confidently offer your clients the safest, strongest and most effective treatment possible.
