Hyperpigmentation in a British Climate: Why It's Trickier Than You'd Think

A clinician's note on the most patient treatment pathway in aesthetics.
The British paradox
Clients often arrive convinced that because we do not get blazing sunshine, pigmentation cannot be sun-driven. UVA — the wavelength most responsible for triggering melasma and worsening post-inflammatory hyperpigmentation — passes through cloud, glass and the windscreen of your car. Pigmentation in a UK face is almost always a layered story: hormonal trigger, UVA-driven amplification, and inflammation from a barrier that has been over-treated by well-meaning skincare. We have to address all three to make real progress.
The two patterns I see most
Melasma — symmetrical, often on the upper lip, forehead and cheekbones, deeper in tone, triggered or worsened by pregnancy, contraception, HRT, or sun exposure. It is a chronic condition we manage, not cure. Most common in Fitzpatrick III to V.
Post-inflammatory hyperpigmentation (PIH) — darker marks left after acne, shaving irritation, eczema or an over-aggressive treatment. More likely to clear with patient management, but persistent in deeper skin tones and easily worsened by the wrong intervention.
What works, in the order I usually do it
One: SPF, properly used. Without this, every other step is wasted. SPF 50, broad spectrum, applied generously, reapplied at midday. Tinted mineral SPF gives an additional small benefit against visible light — helpful in melasma.
Two: a tyrosinase inhibitor. The active ingredients with the best evidence are tranexamic acid, azelaic acid, kojic acid, alpha arbutin, and — in clinic-prescribed form — hydroquinone in short, supervised courses. ZO Skin Health protocols are particularly useful for darker tones because they are designed to manage pigmentation without aggressive bleaching.
Three: gentle exfoliation. A weekly mandelic or lactic acid peel in clinic, or a home regimen built around a tolerable retinoid. We go slowly. PIH in deeper tones can be worsened by aggressive peels — I would rather spend twelve weeks getting it right than four weeks chasing a problem we created.
Four: hydro facial with brightening infusion. Once the barrier is settled and the home regimen is steady, hydro facials accelerate the result. Not before.
What I avoid in UK clients
Aggressive IPL on melasma — it almost always rebounds darker. Deep TCA peels in unprepped skin. Anything 'brightening' bought from an unregulated source online — some still contain hydroquinone at unsafe concentrations or undeclared steroids, and we end up treating the damage.
The honest timeline
Visible improvement in eight to twelve weeks. Genuine progress over six months. Melasma in particular is a long, patient relationship between you, your skincare and your SPF. The clients who win at pigmentation are not the ones who do the most — they are the ones who stay consistent the longest.
