Why stubborn skin pigmentation keeps returning despite skincare routines

Skin pigmentation often feels like a problem that has been solved when a dark patch fades, only for the same discolouration to return weeks or months later. Dr Ashwini Kandikatla, a dermatologist at Dermis Oracle in Mumbai, explains that the core issue is why the skin keeps producing excess pigment in the first place.

UV Rays and Acne

Sun protection is often limited to beach days or long hours outside, but everyday exposure matters just as much for skin that tends to get pigmented. UV radiation stimulates melanocytes, which are the cells responsible for making melanin. This causes existing dark spots to get darker and new uneven patches to form. Visible light can also affect certain pigmentary conditions, especially in deeper skin tones. For many women, pigmentation starts with acne. When acne causes inflammation, it triggers excess melanin production, leading to post-inflammatory hyperpigmentation. Repeated breakouts create new marks before the old ones fade, which is very common in Indian skin where such marks tend to stay longer.

Hormones and Harsh Skincare

Recurring patches do not always have an obvious external cause. Hormones play a major role in melasma, which shows up as symmetrical pigmentation across the cheeks, forehead, or upper lip. People often use more active ingredients, harsh scrubbing, frequent exfoliation, or change products too often to get faster results. This damages the skin barrier and causes inflammation, which then makes the skin produce even more pigment. Home remedies and salon treatments can have the same effect if they cause redness or burning. Dr Ashwini notes that skincare should be judged by how well the skin can tolerate it rather than how intense it feels.

Context

Skin pigmentation treatments often fail when people focus only on removing dark spots instead of finding out why the skin keeps producing extra melanin. Protecting the skin from the sun every single day, treating acne early, and avoiding harsh ingredients help keep the skin barrier safe and healthy over time.
