Pigmentation around the mouth is one of the most common - and most misunderstood - skincare concerns. Whether it appears as darkening on the upper lip, corners of the mouth, chin, or philtrum, perioral hyperpigmentation is not a single condition but a collection of different pigmentation types that share the same area of the face. Hormonal changes, post-blemish marks, sun exposure, friction from hair removal, and skin irritation can all trigger pigmentation in this zone, which is why a one-size-fits-all approach rarely delivers lasting results. In this guide, we break down the five key causes of pigmentation around the mouth, how to identify which type you have, the most effective ingredients to target it, and the skincare routine that can help fade discolouration and prevent it from returning

Uneven skin tone is one of the most common skin concerns, appearing as dark spots, blotchiness, dullness, redness, or patches of discoloration across the skin.

With the right ingredients and a consistent routine, it can be improved. This guide explains what causes uneven skin tone, the ingredients that help visibly brighten and even the complexion, and how to build an effective skincare routine that delivers long-term results.
