What Age to Start Anti-Ageing Treatments

There is no single right age to start anti-ageing skin treatments. There is, however, a wrong way to think about the question and most people are thinking about it that way. Anti-ageing is not something you do when ageing has already happened. It is something you do to slow the rate at which it happens and the biology of skin means that the window to do that meaningfully opens earlier than most people realise.

This guide maps the decade-by-decade picture honestly: what is actually changing in your skin, what treatments are worth considering at each stage and how to think about prevention versus correction so you can make decisions that serve your skin long-term rather than just addressing what you can see today.

The Biology First: What Is Actually Happening to Your Skin Over Time?

Understanding what ageing actually is makes every treatment decision easier. Skin ageing is not a single process. It is the cumulative effect of several distinct biological changes, each accelerating at different rates and influenced by different factors.

Collagen loss begins gradually from around age 25, declining at approximately 1% per year. By age 50, most people have lost roughly 25 to 30% of their peak collagen production. This is the single most significant driver of visible skin changes: loss of firmness, the deepening of lines and the gradual reduction in skin density that makes skin look less full and supported over time.

Cell turnover slows progressively from the mid-20s. In your 20s, your skin regenerates approximately every 28 days. By your 40s this extends to 45 days or more. Slower turnover means dead skin cells accumulate more readily, skin looks duller and surface damage repairs more slowly.

Elastin degradation reduces the skin's ability to spring back to shape after movement. This contributes to the gradual settling of expression lines into permanent creases and the loss of the plumpness that comes from skin being fully supported from below.

UV accumulation is the biggest external driver of premature ageing, responsible for estimates of up to 80% of visible skin ageing over a lifetime. UV damage is cumulative, largely invisible while it is happening and largely irreversible by the time it manifests as pigmentation, texture change and loss of elasticity. This is why sun protection is not optional at any age.

Hormonal changes accelerate the process significantly during perimenopause and menopause. The drop in oestrogen reduces collagen synthesis, skin hydration and the skin's ability to repair itself. Women can lose up to 30% of their skin collagen in the five years following menopause. This hormonal shift is often when patients feel their skin has changed abruptly rather than gradually.

In Your 20s: Build the Foundation

The honest answer for your 20s is that most people do not need clinical aesthetic treatments. What they need is consistent skin protection. The habits you establish in your 20s determine the rate of visible ageing in your 30s and 40s more than almost any clinical intervention will.

The non-negotiables in your 20s are SPF 50 every day without exception, a consistent gentle skincare routine that maintains the skin barrier and avoiding the lifestyle factors that accelerate collagen degradation: smoking, chronic UV exposure, poor sleep and high sugar intake.

Clinical treatments that can be appropriate in the mid-to-late 20s, for the right patient, include medical-grade microneedling to support early collagen stimulation in patients with specific textural concerns and skin booster treatments such as Profhilo for patients whose skin shows early signs of dehydration or reduced elasticity rather than for general prevention. Anti-wrinkle injections are occasionally appropriate in the late 20s for patients with pronounced dynamic lines that are beginning to etch, but conservative use is essential at this stage. If in doubt, wait.

CO2 laser resurfacing is not typically appropriate or necessary in your 20s unless there is a specific indication such as significant acne scarring or a post-surgical scar that warrants treatment. Early collagen is still abundant. The treatment is best directed where the deficit actually exists.

In Your 30s: The Most Impactful Decade for Prevention

Your 30s are where the biology shifts enough to make proactive clinical treatment genuinely worthwhile. Collagen decline has been accumulating for a decade. Cell turnover has slowed noticeably. Early expression lines are beginning to appear. Skin may feel less bouncy and more prone to dullness. If you have had acne in your 20s, any residual scarring is now fully mature and a good candidate for treatment.

This is the decade where the preventative investment has the highest return. Treating skin in your mid-30s when collagen reserves are still relatively healthy produces better outcomes per session than treating the same concerns at 50 when those reserves are significantly depleted. The skin is more responsive, heals faster and the collagen produced by treatment integrates into a dermis that is still reasonably dense.

What to Consider in Your 30s

• CO2 laser resurfacing: From the mid-30s onwards this becomes a meaningful preventative and corrective tool. A single session in your mid-30s can reset years of early sun damage and textural irregularity and extend the skin's healthy density. For acne scar patients, this is the decade where treatment produces some of the most dramatic improvements relative to the pre-treatment baseline.
• Skin boosters: Profhilo and similar hyaluronic acid biostimulators support skin hydration, elastin quality and early firmness. Two sessions per year is a clinically appropriate maintenance cadence for many patients in their 30s.
• Consistent medical-grade skincare: Retinoids, SPF, vitamin C antioxidant support and a well-maintained skin barrier underpin all clinical treatments and should not be treated as optional.
• Microneedling: For patients with early textural concerns, microneedling courses produce meaningful improvement with manageable downtime and are a good starting point before considering more intensive treatments.

In Your 40s: Shifting from Prevention to Regeneration

In your 40s the conversation shifts. Collagen decline has accelerated. Skin laxity around the jaw, jowl and neck becomes more noticeable. Expression lines deepen. Perimenopause adds a hormonal layer to the structural changes that are already underway. The skin is still highly responsive to treatment, but it needs more intervention to produce the same degree of improvement than it would have required ten years earlier.

This is also the decade where patients often feel the gap between what they see in the mirror and how they feel. The treatments available at 40 are significantly more effective than they were even a decade ago and for most patients a thoughtfully designed treatment plan produces genuinely meaningful results without surgical intervention.

What to Consider in Your 40s

• CO2 laser resurfacing: In your 40s, CO2 laser shifts from prevention to active regeneration. The collagen produced by treatment compensates for the natural deficit in a way that becomes increasingly important as the decade progresses. For patients with significant sun damage, textural changes or established scarring, this is often the most impactful single intervention available non-surgically.
• Skin tightening: Our skin tightening protocols become relevant for patients experiencing laxity in the jaw and neck area. CO2 laser produces genuine structural tightening through the wound healing contraction mechanism and the sustained Type I collagen production that follows.
• Biostimulators: Profhilo and polynucleotide treatments support dermal hydration and elastin quality in a way that pure collagen stimulation treatments do not address. Many patients in their 40s benefit from combining a collagen-stimulating treatment with a biostimulator for a more comprehensive result.
• HRT considerations: If you are perimenopausal or post-menopausal, hormone replacement therapy supports collagen maintenance in a way that no topical or clinical aesthetic treatment can match at the hormonal level. We are not prescribers, but we factor HRT status into every treatment plan we design for patients in this age group because it is clinically relevant.

In Your 50s and Beyond: Maintenance, Regeneration and Honest Expectations

The most important thing to say about treating skin in your 50s and beyond is that it absolutely responds to treatment. Collagen reserves are lower and the skin heals more slowly than it did twenty years earlier, but the biological mechanisms that CO2 laser and other regenerative treatments activate are still fully functional. The outcomes are different from treating the same concerns in your 30s, but they are meaningful and often genuinely transformative for patients who have not had clinical treatment before.

Honest expectation management is essential in this decade. Non-surgical treatments cannot replicate the results of surgical intervention for patients with significant skin redundancy or very advanced structural laxity. We will always tell you clearly if we feel surgery is the more appropriate pathway and we will direct you accordingly.

What to Consider in Your 50s and Beyond

• CO2 laser resurfacing: Remains highly effective and is often the treatment that patients who start in their 50s find most impactful. The collagen stimulated by treatment meaningfully compensates for the natural deficit. For patients with significant sun damage and textural irregularity accumulated over decades, the improvement can be striking.
• Scar revision: Post-surgical scars from procedures earlier in life, including caesarean scars and other surgical sites, remain excellent candidates for CO2 laser treatment regardless of how long they have been present. See our scar removal page for full details.
• Maintenance cadence: Patients who have had CO2 laser earlier in life typically maintain with lighter treatment every two to four years. Patients starting for the first time in their 50s often benefit from two to three initial sessions before moving to a maintenance schedule.
• Lifestyle foundations remain critical: SPF 50 every day, adequate protein intake to support collagen synthesis, not smoking and managing UV exposure continue to determine the rate of ageing between treatments far more than most patients appreciate.
