A market built on insecurity
The global skincare industry generates well over US$150 billion a year. A meaningful portion of that revenue comes from products marketed at women in their 40s and beyond, often with packaging and claims engineered to suggest dramatic transformation. The result is a confusing landscape where genuinely effective ingredients sit on the same shelf as expensive saline, where credible science sits next to marketing built on insecurity, and where it's increasingly hard for women to know what's worth their time and money.
Here's what the evidence actually supports and where to be sceptical.
What changes about skin in midlife
Three biological shifts dominate.
Collagen and elastin production decline. Skin loses roughly 1% of its collagen per year from around age 20, with a steeper decline after menopause. Collagen is what gives skin its firmness and structure; less collagen means thinner skin and more visible fine lines.
Cell turnover slows. Younger skin replaces itself roughly every 28 days. By midlife, that cycle stretches to 40–60 days, which contributes to dullness, uneven texture, and slower healing.
Oestrogen-related changes. Falling oestrogen levels affect skin hydration, oil production, wound healing, and how the skin retains moisture. Many women notice their skin becoming drier, more reactive, or differently textured during perimenopause.
These changes are normal and universal. They're also influenced by genetics, sun exposure, sleep, stress, smoking, alcohol, and overall health many of which are more impactful than any product.
What the evidence actually supports
The skincare ingredient list with the strongest evidence base is shorter than the marketing might suggest.
Sun protection. Daily broad-spectrum SPF is the single most evidence-supported intervention for skin ageing. Studies consistently show that consistent sun protection slows the visible signs of photo ageing more than any active treatment. If you do nothing else, do this.
Topical retinoids. This category has decades of clinical evidence behind it for improving skin texture, fine lines, pigmentation, and overall skin quality. Some retinoid products are available over-the-counter at lower strengths; stronger forms require a prescription and medical assessment. A doctor can advise on what's appropriate for your skin type, sensitivity, and goals.
Vitamin C (L-ascorbic acid). Antioxidant protection against environmental damage, with reasonable evidence for brightening and supporting collagen synthesis. Formulation matters substantially — many vitamin C products on the market are unstable and degrade quickly.
Niacinamide. Well-tolerated by most skin types, with evidence supporting its role in barrier function, redness reduction, and improving skin texture.
AHAs and BHAs (chemical exfoliants). Glycolic acid, lactic acid, and salicylic acid have evidence for improving skin texture and tone when used appropriately. Overuse causes irritation and damage.
Moisturisation and barrier support. Ceramides, hyaluronic acid, and well-formulated moisturisers genuinely matter, particularly as skin becomes drier in midlife. A compromised skin barrier is the cause of many problems people try to treat with active ingredients.
That's most of the evidence-supported list. Many of the other ingredients featured prominently in marketing have weaker evidence, work only in specific contexts, or are present in concentrations too low to do much.
What's mostly marketing
A few categories worth being sceptical of:
Most "anti-ageing" claims on consumer products. Therapeutic claims about reducing wrinkles, reversing ageing, or producing dramatic transformation are tightly regulated in Australia under the Therapeutic Goods Act. Cosmetic products are not allowed to make therapeutic claims. When a cosmetic product is heavily marketed on dramatic outcomes, scrutinise carefully.
Stem cell skincare. The science is interesting in laboratory contexts; the consumer products marketed under this banner generally have very limited evidence.
Most expensive serums. Price is a poor proxy for efficacy. Many of the most evidence-supported active ingredients are available in well-formulated, affordable products.
"Detox," "purifying," and "toxin-removing" claims. Skin doesn't accumulate toxins that need removing. These are marketing terms with no clinical meaning.
Single products promising to do everything. No single product can simultaneously brighten, firm, hydrate, exfoliate, and protect at meaningful concentrations. The hero-product marketing model rarely matches the science.
When to consider professional input
Lifestyle and good over-the-counter skincare get most women a long way. Medical input becomes worth considering when:
- You want evidence-based guidance personalised to your skin type, age, and goals
- Pigmentation, texture, or skin health concerns aren't responding to consistent skincare
- You're spending significant amounts on skincare with limited results and want to understand what's actually worth it
- You're considering stronger interventions and want a doctor's clinical assessment first
- You have a skin condition (rosacea, eczema, persistent acne, sun damage) that needs medical assessment
A doctor can take a history, look at your skin, and discuss what may be appropriate for your individual situation. That conversation will look different for every patient.
What good skin care actually involves
A short list of what tends to matter most:
- Daily sun protection. Year-round, not just summer.
- A simple, consistent routine. A few well-chosen products used consistently outperform a complex routine used sporadically.
- Sleep, hydration, nutrition. All visibly affect skin over months.
- Patience. Visible skin changes take 8–12 weeks at minimum to show. Short trials of new products tell you very little.
- Stopping things that don't work. If a product isn't doing anything after 3 months, it's not going to.
- Professional input when appropriate. Not for everyone, not for everything, but worth considering when DIY hits its limits.
How Zibby Health approaches skin health
Zibby Health is an Australian Telehealth service launching mid 2026, including doctor-led consultations focused on skin health. Each consultation involves a private discussion with an AHPRA-registered Australian doctor about your skin, your history, what you've tried, and what your goals are. Whether next steps involve guidance, further investigation, or other options is determined entirely by the doctor's individual clinical assessment.
If you'd like to be among the first 100 women to access an early-bird consultation when Zibby Health opens, you can reserve your spot here.
The takeaway
Most of what the skincare industry sells is marketing. The handful of ingredients and habits that actually move the needle are well-known, generally affordable, and broadly accessible. Where personalised medical input adds value is in helping you skip the noise and focus on what's actually likely to work for your specific skin.
