What is Exolase One Laser?

The treatment is built on ONEpulse technology, which delivers both laser wavelengths to the same point on the skin at the same time. The Erbium:YAG component works at the skin's surface, removing a controlled, superficial layer, while the Erbium:Glass component works more deeply to stimulate the skin's own collagen production, rather than treating these separately in multiple passes.

Exolase One is designed to address five common signs of skin ageing together: textural irregularity, fine lines and wrinkles, pigmentation, redness and skin laxity.

Exolase One is administered by our Aesthetic Doctors or Dermal Therapists following a private consultation at our Mayfair clinic, 49 Charles Street, London W1J 5EN.

A full face treatment can typically be completed in under ten minutes, delivered in a single pass.

Most patients describe Exolase One as comfortable, with any sensation often likened to mild warmth or tingling rather than pain. Your practitioner can discuss comfort options and what to expect at your consultation.

Exolase One is designed to involve less downtime than traditional ablative lasers. Most patients experience mild, short-lived redness rather than the prolonged peeling and crusting associated with older-generation laser resurfacing. Your practitioner will advise on what to expect based on the intensity of treatment selected.

A course of one to three treatments, typically spaced four to six weeks apart, is generally recommended, with the exact number depending on your skin condition and goals.

Traditional ablative lasers typically treat the skin in multiple passes, or require switching between separate devices, often with longer sessions and a longer recovery. Exolase One's fused-wavelength approach is designed to deliver comparable collagen remodelling in a single pass, with a shorter treatment time and less downtime.

Suitability is assessed individually at consultation, taking your skin tone and history into account. Your practitioner will confirm whether Exolase One is right for you.

Exolase One tends to suit those looking to improve overall skin quality, whether addressing early signs of ageing or more visible concerns around texture, pigmentation, redness or laxity. As with any laser treatment, suitability depends on your individual skin type and history, which is why every treatment at Le Petit Saint begins with a private consultation.
