Spider veins and small varicose veins affect millions of people worldwide, causing discomfort and self-consciousness. Traditional treatments often fall short in delivering lasting results or involve invasive procedures with long recovery times. CLACS treatment offers a new path forward by combining laser therapy, cryotherapy cooling, and sclerotherapy injections into one effective, minimally invasive solution. This approach targets both visible veins and their underlying feeders, reducing recurrence and improving cosmetic outcomes.

What CLACS Treatment Means for Spider Vein Removal
CLACS stands for Cryo-Laser and Cryo-Sclerotherapy. Developed by Brazilian vascular specialist Roberto Miyake, it has gained recognition in vein clinics globally. The treatment uses a long-pulse Nd:YAG laser to close feeder veins beneath the skin, while a cooling device protects the skin and reduces discomfort during the procedure. Following laser therapy, a sclerosant solution is injected into the spider veins to collapse and absorb them naturally.
This combination addresses the root causes of spider veins more effectively than traditional sclerotherapy alone. Patients experience less pain, fewer side effects, and better cosmetic results.
How CLACS Treatment Works Step by Step
Laser Treatment Targets Feeder Veins
The first step uses a 1064 nm Nd:YAG laser to deliver heat energy deep into the skin. This energy targets hemoglobin in the blood vessels, causing the feeder veins to collapse and close off. Closing these feeder veins prevents blood from pooling and feeding the spider veins on the surface.
Cryotherapy Cooling Protects the Skin
During laser application, a cold air device blows cool air onto the skin. This cooling reduces pain and protects the skin from heat damage. Patients report feeling more comfortable throughout the procedure, which helps reduce anxiety and improves overall experience.
Sclerotherapy Injection Collapses Spider Veins
After laser treatment, the doctor injects a small amount of sclerosant medication directly into the spider veins. This solution irritates the vein walls, causing them to collapse and eventually be absorbed by the body. Combining this with laser treatment of feeder veins reduces the chance of spider veins returning.
Conditions Treated Effectively with CLACS
CLACS is suitable for a range of vein issues, including:
Spider veins (telangiectasia) on legs and face
Reticular veins, which are small blue or green veins under the skin
Small varicose veins that cause discomfort or cosmetic concerns
Complex leg vein networks that are hard to treat with sclerotherapy alone
This treatment is especially useful for veins that have resisted traditional therapies or for patients seeking a less invasive option.
Benefits That Make CLACS Stand Out
Patients and doctors choose CLACS for several reasons:
Minimally invasive with no need for surgery or large incisions
Reduced pain thanks to cryotherapy cooling during laser treatment
Lower risk of recurrence by treating feeder veins and surface veins together
Quick procedure time, often completed in under an hour
Minimal downtime, allowing patients to resume normal activities soon after
Improved cosmetic results with smoother, clearer skin
For example, a patient with persistent spider veins on the legs who previously tried sclerotherapy without success may find CLACS offers a more lasting solution. The combined approach addresses the veins beneath the surface, which traditional methods often miss.
What to Expect During and After Treatment
CLACS treatment usually takes 30 to 60 minutes depending on the area treated. Patients may feel a mild warming sensation from the laser and a cool breeze from the cryotherapy device. The sclerotherapy injections cause minimal discomfort and are well tolerated.
After treatment, some redness or mild swelling may occur but typically resolves within a few days. Patients are advised to avoid sun exposure and strenuous exercise for a short period. Compression stockings may be recommended to support healing.
Most people see visible improvement within weeks, with continued fading of veins over several months. Multiple sessions may be needed for optimal results depending on vein size and extent.
Who Should Consider CLACS Treatment
CLACS is ideal for adults with spider veins or small varicose veins who want an effective, low-pain treatment without surgery. It suits those who have tried other therapies with limited success or want to avoid the risks and downtime of invasive procedures.
People with certain medical conditions or allergies should consult a vascular specialist to determine if CLACS is safe for them. A thorough vein assessment helps create a personalized treatment plan.
Final Thoughts on CLACS for Spider Vein Removal
CLACS treatment offers a clear advantage for those seeking to improve vein health and appearance. By combining laser therapy, cryotherapy cooling, and sclerotherapy injections, it targets both visible veins and their underlying causes. This results in less pain, fewer treatments, and better long-term outcomes.
If spider veins affect your confidence or comfort, discussing CLACS with a qualified vein specialist can open new possibilities. This treatment represents a practical, patient-friendly option that moves beyond traditional methods. Taking this step can help you enjoy smoother skin and renewed confidence in your legs and face.
