Many clients are surprised when their pigmentation suddenly appears darker during the winter months. Even though we associate pigmentation with summer sun, it is often far more noticeable once the weather turns colder. At Skinportant Clinic, we see this every year, and there are several reasons why it happens. Understanding these reasons can also help you manage and reduce pigmentation more effectively.
During the summer, your skin naturally produces more melanin to protect itself from UV light. This often creates a subtle, even glow that can disguise uneven pigment. When winter arrives and UV levels drop, your overall melanin production slows down. As your tan fades, any existing pigmentation becomes more visible against a lighter complexion. The pigment has not suddenly darkened; it simply contrasts more sharply with the surrounding skin.
Cold air, central heating and low humidity all contribute to a weaker skin barrier. When your skin is dry or dehydrated, it loses its natural ability to reflect light evenly. This makes dark patches appear deeper and more defined. Dry skin can also feel rougher, which emphasises texture and uneven tone.
In colder months, the skin’s natural exfoliation process becomes slower. Dead skin cells build up on the surface, making pigmentation look dull and stubborn. Without regular, gentle exfoliation and appropriate skincare, pigmented areas remain visible for longer.
Although UVB light decreases significantly in winter, UVA levels remain consistent throughout the year. UVA rays penetrate through clouds and windows and are one of the main triggers for pigmentation. Many people reduce or stop using SPF during the winter, which allows ongoing UVA exposure to deepen existing pigment. Indoor lighting, particularly screens, may also play a role in worsening uneven skin tone.
When all these factors combine, pigmentation naturally stands out more.
Key contributors include:
Supporting the skin through winter can make a significant difference. Daily SPF, regular hydration, gentle exfoliation and professional treatments help keep pigment under control.

Wearing foundation every day can put stress on your skin — not just because of the silicones and chemicals in the product, but because foundation creates a film that stops the skin from breathing freely. The biggest issue, however, is the daily removal. Taking foundation off every single night requires stronger cleansers, more friction and repeated stripping of the skin’s natural oils, which can weaken the skin barrier over time.

Skin purging is a normal, temporary reaction that can happen when active ingredients or advanced treatments speed up cell turnover, bringing underlying congestion to the surface. It typically lasts 1-3 weeks and often appears in areas where you already break out.

The rise of K-beauty has led many to believe that all Korean skincare is superior — but with over 4,500 cosmetic manufacturers in South Korea, quality varies greatly. At Skinportant Clinic, we’ve seen clients with damaged barrier layers from 10-step routines and constant product layering. While some Korean brands produce excellent products, assuming all K-skincare is as effective or safe as regulated European formulas is misleading. True skin health comes from evidence-based formulations, ingredient integrity, and simplicity — not the country on the label.
