Carboxy Therapy is a highly versatile treatment that targets a wide range of aesthetic concerns across both the face and body. It works by stimulating microcirculation and improving oxygen delivery to the tissues, which in turn supports natural cellular repair and regeneration. This makes it an excellent option for areas where signs of aging or poor circulation are visible.

Around the eyes, Carboxy Therapy helps reduce puffiness and lighten dark circles by enhancing blood flow and promoting skin renewal. On the body, it is particularly effective at softening the appearance of cellulite and stretch marks by stimulating collagen production and firming the skin from within. A clinical study published in the Journal of Cosmetic Dermatology demonstrated significant improvement in periorbital dark circles following Carboxy Therapy treatments, highlighting its efficacy in this delicate area.

For individuals dealing with skin laxity—especially in the abdomen, thighs, or arms—Carboxy Therapy offers a non-invasive way to achieve smoother, more toned skin. It can also support the breakdown of localized fat deposits, especially when combined with complementary treatments like red light therapy for enhanced results.

The injection of carbon dioxide gas increases circulation in the treated area, which encourages the production of collagen and elastin, leading to firmer, more youthful-looking skin.

For enhanced results, Carboxy Therapy can be combined with Red Light Therapy. While Carboxy boosts blood flow and stimulates collagen from within, Red Light Therapy penetrates deep into the skin to accelerate cellular regeneration and reduce inflammation. This powerful combination supports your skin’s natural healing on multiple levels—helping you achieve smoother texture, improved elasticity, and a healthier overall glow with minimal downtime.

Side effects are minimal but may include mild redness or swelling at the injection site, which typically resolves within a few hours.

There is no downtime with carboxy therapy, making it a convenient treatment for those with busy schedules. You can return to your regular activities immediately.

We typically recommend a series of 4–8 treatments, depending on your individual skin needs and goals.

Carboxy Therapy is not recommended for individuals with certain medical conditions, such as severe cardiovascular disorders, uncontrolled diabetes, active infections, or pregnancy. Please consult with our expert practitioners to determine if this treatment is right for you.
