Although the answer to this question is not well defined, for now we can mention that most of the anti-cellulite products available on the market have at least one natural extract among their ingredients.
Commercial products to treat cellulite work by increasing microvascular flow, inducing lipolysis, restoring the structures of the dermis and connective tissue; and preventing damage to connective tissue caused by free radicals.
However, most of the active molecules in these products are inefficient, since they cannot penetrate the skin, because it has natural properties that act as a barrier.
The ideal delivery system would be to treat the deeper layers of the skin using painless, biodegradable and easy-to-use self-administration alternatives.
So, getting closer to a fair answer, we could say that essential oils can help reduce, and also prevent cellulite, since they can easily penetrate the skin tissues and then gently work on them thanks to their natural origin.
In short, cellulite is a skin condition that causes changes in its appearance, with a texture similar to orange peel skin.
This usually occurs near the buttocks, upper legs, abdominal area and upper arms, due to the expansion of the fat lobes out of their connective framework and into the dermis.
Cellulite can become a pathologically complicated condition that is associated with decreased microcirculation, edema, excessive growth of adipocytes, oxidative stress, ongoing inflammation, and dramatic changes in the extracellular matrix.
It is estimated that 90% of women over 20 years of age suffer from cellulite, and only 2% of men.
On the other hand, estrogen and blood flow decrease as a woman advances in age, which produces an increase in the size of fat cells, which in turn causes an expansion in fat deposits.

Cellulite, therefore, is believed to be a multifactorial condition in which it occurs is thought to be mainly associated with:
