Decoding hyperpigmentation & uneven skin tone

Hyperpigmentation, dark spots, or uneven skin tone are familiar skin concerns, marked by dark patches or spots that pop up when melanin - the pigment behind our skin, hair, and eye colour- goes into overdrive. It’s a common issue across ethnicities and regions, often denting confidence and sparking frustration. But what causes these stubborn marks, and how can we tackle them?

What is hyperpigmentation - the melanin process 

Melanin starts its journey in melanocytes, specialised cells tucked into the basal layer (innermost layer) of the skin’s epidermis (outermost layer). These cells churn out melanin through a finely tuned process, packaging it into tiny sacs called melanosomes. From there, melanosomes transfer into neighbouring cells called keratinocytes. These cells travel upward through the skin’s layers and as they rise, melanin becomes visible, giving your skin its tone. 

In healthy skin, this pigmentation process works in harmony to create an even complexion. However, external and internal factors—such as UV exposure, hormonal changes, and post-inflammatory responses—can disrupt this balance. The result is a buildup of melanin in certain areas, leading to hyperpigmentation, visible as dark spots, uneven skin tone, or discolouration on the face.

Melasma

Melasma is a distinctive form of hyperpigmentation characterised by the development of brown or gray-brown patches on the skin, typically on the face. This condition is particularly associated with hormonal fluctuations and is often referred to as the "mask of pregnancy" due to frequently affecting pregnant women.

The hormonal changes, such as those occurring during pregnancy, contraceptive use, or menopause, play a significant role in the development of melasma. When going through any of these hormone fluctuations, the levels of reproductive hormones are altered. This can affect the stimulation in the production of melanin in our skin. This happens by estrogen acting directly on melanocytes (the cells that make pigment) which in turn causes more pigment production. 

How to reduce hyperpigmentation

The Emma Lewisham Skin Reset Serum was developed with a deep understanding of the underlying causes of hyperpigmentation, specifically to target and correct uneven skin tone. 

Engineered with specialised bioactive ingredient complexes, this formulation targets five key points of the cellular processes that contribute to hyperpigmentation, helping achieve superior results 

In addition, SPF is a non-negotiable in managing hyperpigmentation. This is because all forms of hyperpigmentation can be promoted by UV radiation exposure – whether it be melasma, post-inflammatory, or age spots.
