Infinity Laser

Infinity is a non‑ablative 1450 nm diode laser treatment for active acne that targets the mid‑dermis, where sebaceous (oil) glands sit, to reduce inflammation and breakouts while leaving the surface of the skin intact. The wavelength is strongly absorbed by water in the dermis, creating controlled heat that remodels collagen and thermally affects sebaceous glands, leading to fewer inflammatory lesions, smoother texture and longer remissions compared with many light‑only therapies.

    • 1450 nm infrared light penetrates into the mid‑dermis and is absorbed by water in and around sebaceous glands, generating controlled thermal injury in this layer.

    • This heat damages overactive sebaceous glands and alters the environment that supports C. acnes bacteria, which helps reduce inflammatory papules, pustules, nodules and cysts.

    • Histology and clinical data show collagen remodelling and gland alteration after treatment, which explains improvements in acne lesions, early atrophic scars and overall texture.

  • Infinity‑type 1450 nm diode laser is primarily used for:

    • Mild to moderate inflammatory facial acne, especially when patients wish to reduce or avoid long‑term antibiotics or systemic medication.

    • Oily, congestion‑prone skin and early atrophic acne scarring, where dermal remodelling is beneficial.

    Treatments are most commonly performed on the face, but protocols can be adapted for acne on the chest or back in appropriate candidates.

  • Clinical studies typically use a course of up to 3–5 sessions, spaced about 2 weeks apart, with improvement in inflammatory lesion counts of around 40–60% over 2–3 months after the final session. During and immediately after treatment, patients usually experience warmth, redness and transient swelling; erythema often settles within 24–48 hours, with low rates of more significant side‑effects when parameters and cooling are appropriately managed.

  • Many patients see progressive reduction in red, inflamed spots and overall improvement in skin clarity over the treatment course, with some studies reporting sustained remission months after the last session. As with all laser acne therapies, strict sun protection is essential, and while the 1450 nm diode laser has been shown to be effective and generally well tolerated even in darker skin types, there remains a small risk of post‑inflammatory hyperpigmentation that is minimised by correct settings, cooling and aftercare.
