Skin laxity is caused by the gradual breakdown of collagen and elastin— the structural proteins that keep skin firm and resilient. There are three primary drivers: chronological ageing, which causes progressive collagen degradation over time; hormonal changes, particularly the rapid oestrogen loss that occurs during menopause; and volume loss, including the structural changes that follow significant weight loss. These three factors often coexist and compound each other, which is why treatment needs to address the dominant drivers rather than take a one-size-fits-all approach.

Collagen production begins declining from around age 20, at approximately 1% per year. Visible laxity — the kind you'd notice in the mirror — typically becomes apparent from the mid-30s onwards, progressing through the 40s and 50s as jowl formation, nasolabial folds, and neck laxity develop. The rate of change accelerates significantly around menopause, when oestrogen loss causes collagen to decline at roughly twice the normal rate. That said, timelines vary considerably based on genetics, sun exposure, and hormonal status.

Yes. A range of non-surgical treatments can meaningfully improve skin firmness and lift — including Sofwave ultrasound, RF microneedling, focused radiofrequency, and cosmetic injectables. Results depend on the degree of laxity, skin quality, and individual response. The best outcomes come from a personalised, staged plan that addresses what's actually driving the change in your skin — not a single treatment applied without assessment.

Significantly. Oestrogen directly supports collagen synthesis, elastin production, skin thickness, and hydration. When oestrogen levels drop at menopause, collagen loss accelerates — studies show a reduction of approximately 2.1% per post-menopausal year in the first five years, which is twice the rate of age-matched women before menopause. Patients often describe a sudden acceleration of ageing during this period. The first five years post-menopause are the most critical— early intervention during this window can meaningfully preserve skin quality and slow visible progression.

Sofwave uses clinically proven ultrasound technology to stimulate your skin's own collagen production — lifting and firming from the inside out, with no needles, no downtime, and no recovery time needed. In clinical studies, 86% of patients showed measurable skin improvement at 12 weeks, and 80–85% reported visible improvement in overall appearance. A full-face treatment takes around 45 minutes, and you can return to your day straight after. Sofwave is safe for all skin tones and types. Brains Aesthetics was one of the first clinics in Melbourne to introduce Sofwave, and it remains our most requested treatment for skin laxity and loss of firmness.

Clinical data sourced from published Sofwave studies measuring improvement on the Fitzpatrick Wrinkle and Elastosis Scale and Global Aesthetic Improvement Scale (GAIS) at 12 weeks.

Sofwave uses synchronised ultrasound energy to target the mid-dermis without breaking the skin surface — meaning no downtime and no healing period. It is the most direct option for laxity where skin quality is good. RF microneedling combines radiofrequency energy with controlled micro-injuries to stimulate collagen remodelling — particularly effective when laxity is accompanied by texture concerns, though it involves 24–48 hours of redness and mild sensitivity. Focused 3DEEP RF delivers volumetric heating to tighten and sculpt, and is well suited to the jaw and neck. Your clinician will assess your skin quality and laxity severity before recommending the most appropriate option.

This depends on the treatment and the degree of laxity. Sofwave typically delivers noticeable results from a single session, with continued collagen remodelling over 12 weeks. Advanced laxity may benefit from two sessions. RF microneedling and focused RF are often recommended in a course of three sessions. For more complex presentations — including post-menopausal skin or significant weight loss — a staged treatment plan across several months will give the best long-term outcome. Your consultation will give you a realistic picture of what to expect and when.

Most skin laxity treatments at Brains Aesthetics involve minimal to no downtime. Sofwave has no downtime — you can return to your day immediately. RF microneedling involves 24–48 hours of redness and mild sensitivity. Fractional laser resurfacing has the longest recovery of the options we offer, typically 3–5 days of visible peeling. Your clinician will discuss what to expect at your consultation so you can plan accordingly.

Yes — and the approach depends on how much weight was lost and whether your weight has stabilised. Significant weight loss, including through medications, causes a combination of true skin laxity and volume deflation — particularly in the mid-cheek, temples, and neck. These require a different treatment sequence to age-related laxity alone. Weight stabilisation is an important factor before structural treatment begins, so we're working with your final facial structure rather than a moving target. We offer a dedicated Skin Changes After Weight Loss consultation specifically for this presentation.
