Anti-aging is one of the most searched topics in skincare — and one of the most misunderstood. The market is flooded with products making bold claims, but the evidence base for most of them is thin. Here is what the science actually supports.

Retinoids: The Gold Standard

Retinoids — a family of Vitamin A derivatives — remain the most extensively studied anti-aging ingredient in dermatology. Prescription-strength tretinoin has decades of randomised controlled trial data showing it increases collagen synthesis, accelerates cell turnover, and visibly reduces fine lines, pigmentation, and skin texture.

Over-the-counter retinol is a milder precursor that the skin converts to retinoic acid. It is a good starting point for those new to retinoids, though it requires patience — consistent use over 12 weeks is typically needed before visible results appear. Begin with a low concentration two to three nights per week, always followed by a moisturiser, and introduce sun protection as a non-negotiable morning step.

Professional Treatments Worth Considering

For more significant concerns, a range of in-clinic treatments offer outcomes that topicals cannot match. Chemical peels using glycolic acid, salicylic acid, or TCA can resurface the skin at varying depths, addressing pigmentation, texture, and mild laxity. Micro-needling stimulates collagen induction through controlled micro-injury, with results that improve over several sessions.

Energy-based devices — including radiofrequency, ultrasound (such as HIFU), and fractional laser — target deeper layers to stimulate collagen remodelling and improve skin laxity without surgery. These treatments require skilled administration and a personalised approach, which is why a consultation with a qualified dermatologist is always the right first step.

What to Be Sceptical Of

Collagen supplements, facial rollers, LED masks available for home use, and the vast majority of 'anti-aging' serums have limited or no robust clinical evidence behind them. This does not mean they are harmful — but it does mean you should not substitute them for proven interventions.

At Nova Doc, we take a methodical, evidence-led approach to anti-aging. Every treatment recommendation is based on your skin's individual condition, not on what is trending. Book a consultation and let's build a plan that genuinely works for you.
