Stretch Marks: Treat them when they're new and/or pink! The fresher the marks are, the easier they are to get rid of. Microderm and laser treatments in conjunction with topical treatments are very effective methods for fading or eliminating your stretch marks. You will need a series of treatments (depending on your situation). Free consultations are available at any good medspa or laser clinic, and they should be able to tell you exactly what you can expect as far as the treatment, # of sessions, results, and cost.
For cellulite, there's a range of treatments from more invasive surgical options such as tumescent liposuction, SmarLipo…or minimally invasive options like Endermologie (massage) or Mesotherapy (saline injections). Another treatment, called VelaSmooth is a laser procedure that is also effective at melting fat deposits. Remember, these treatments are effective for people with excercise resistant fat cells and NOT for people with moderate to extreme weight problems. In other words, this is for toning, not for weight loss. Hope this helps. Check out the link below for more info and for clinics and medspa in your area. Go in for a consultation…it's definitely worth your time!
First you should find out why you have cellulite and fight it from there.
You need to activate your metabolism by doing proper physical exercise and intake more fluids. Perhaps reasonable walking, exercising and/or swimming would do. This should stimulate the elimination of toxins in your body. It is important that you activate your system before you start decomposing the cellulite structure.
Drink enough water and/or diuretic teas. Diuretic teas range from mild diuretics (Rosehip) to teas specially mixed for fighting cellulite which you can buy in the pharmacy.
Eat properly. An example of diuretic food are cucumber and parsley. Eat lots of fiber and combine your food properly and in proper quantities. Congestion followed by constipation, is the killer.
Use special creams to prepare your skin for the stress, as well as to treat it afterwards. This way you would avoid stretch marks. Stretch marks are best treatable in early stage.
Anti cellulite gels are good for the superficial decomposition of cellulite. Give it a try.
Massage is essential. You do need to have someone massage it away, with special oils and wrapping, etc. This is combined with specific treatments used in salons, where practically everything is applicable and, unless you are unlucky with the salon choice, under control.
When you start crunching the cellulite, at the beginning it may appear that you have more of it, because the deeper layers would go to the surface. Don't panic. This is temporary. I'm saying this because perhaps you are aware that summer is coming and you've found your long lost thighs 
You must strive throughout. Bad experience is with peoples who remember of their body only before summer comes, and those who simply are looking for a one day wonder after years of mistreating their body. Think of it as a long term commitment to fight cellulite and you are on the right path.
Frequently asked questions:
Q: Is coffee bad for cellulite?
A: People usually drink coffee after a heavy meal, every day and in larger quantities. It usually all sums up into a nice heavy congestion. Drinking coffee on empty stomach, and in reasonable quantity is not bad for cellulite.
Q: What is the fastest way to get rid of cellulite?
A: Liposuction.
Q: Is exercising and diet enough to get rid of cellulite?
A: No. It needs to be treated locally.
Because cellulite is beneath the surface of the skin and can also be genetic, most of us need that extra push to see results. I would suggest reseaching Mesotherapy and Lipodissolve…both are proven to be highly effective at breaking down fat cells through sodium deoxycholate and other active agents and flushing them naturally out of the body. If you combine these treatments with drinking lots of water and exercise, I think you'd be suprised by how quick and effective the treatments are. You should consult with a specialist though, to determine exactly what results you can expect and if the treatment is right for you.
You can use the websites below for research or to schedule a free consult with a practice near you. Oh, and you might also want to research VelaSmooth and Endermologie….different methodologies for treatment, but again….noticeable results. Hope this helps!
exercise also helps tremendously.
but, there isn't a surefire way to just completely get rid of it. even lipo doesn't do it!
Not to be a killjoy – but if you check into "cellulite" on the internet, it may provide you with creams that will temporarily shrink the tissue (mostly remove the water in the tissue) to make it look smaller; however, despite your slim, petitie figure, which many girls would envy and whatver celluite you are talking about is most likely negligilble, the only permanent solution would be liposuction, which will run you about $2,000 (depending on location) at least for both thigh/hips.
Upside…the fat that has developed is permanently gone.
Downside…is depending on extent of liposuction, infection could occur and cause illness or, worst case scenario (which is on the Court TV Channel) is if you have a tendency toward diabetes and it could result in amputation of one or both limbs. Lesser downside is if all goes fine and you gain weight for whatever reason, your fat cells in that area could develop again.
With being so tiny and slim though, you probably think your problem is worse than it is… best solution if you really are that self-conscious is to wear slightly longer short, slightly lower necklines, slightly more make-up and slightly bigger (but not '80's!) hair.
