Many women notice that their skin suddenly becomes darker, patchier, or uneven during pregnancy or in their late 30s to 40s.
If you’re wondering why this happens — it is usually hormonal.
At Healthsprings Laser & Aesthetic Clinic Singapore, we commonly see women experiencing pigmentation changes linked to pregnancy and perimenopause. These are not random skin issues — they are hormone-driven.
What Is Hormonal Pigmentation?
Hormonal pigmentation refers to skin darkening caused by changes in hormone levels, particularly:
-
Oestrogen
-
Progesterone
-
Melanocyte-stimulating hormone (MSH)
These hormones influence melanocytes, the cells responsible for producing melanin (the pigment that gives skin its colour). When hormone levels fluctuate, melanocytes may become overactive, leading to increased pigment production.
This can appear as:
-
Brown or grey-brown patches on the face
-
Symmetrical pigmentation on the cheeks, forehead, or upper lip
-
General uneven skin tone
The most common form of hormonal pigmentation is melasma.
Why Does Pregnancy Cause Pigmentation?
During pregnancy, the body undergoes significant hormonal changes. Levels of oestrogen and progesterone increase, and melanocyte-stimulating hormone also plays a role in activating pigment production.
These hormonal changes can make the skin more sensitive to sunlight. As a result, even limited exposure to ultraviolet (UV) radiation may trigger pigmentation.
Common features of pregnancy-related pigmentation include:
-
Dark patches on the cheeks and forehead
-
Pigmentation on the upper lip
-
Worsening of existing freckles or spots
-
Darkening of certain body areas, such as the abdominal line (linea nigra)
This condition is often referred to as the “mask of pregnancy”.
In some cases, pigmentation may improve after delivery. However, it can persist in others, particularly if triggered by ongoing sun exposure.
Why Does Perimenopause Trigger Pigmentation?
Perimenopause, which typically occurs in the late 30s to late 40s, is characterised by fluctuating hormone levels, rather than consistently elevated levels.
These hormonal changes can disrupt normal melanin regulation.
In addition, cumulative sun exposure over the years may become more visible during this phase, contributing to pigmentation.
Patients may notice:
-
New dark patches appearing in their 40s
-
Worsening of existing pigmentation
-
Increased skin sensitivity
-
Changes in overall skin texture
These changes are not solely due to ageing, but are often influenced by hormonal transition.
Management of Hormonal Pigmentation
The approach to managing hormonal pigmentation depends on several factors, including:
-
Whether the patient is pregnant or breastfeeding
-
The severity and depth of pigmentation
-
Skin type and sensitivity
-
Hormonal stability
At Healthsprings Laser & Aesthetic Clinic in Singapore, management plans are individualised, and selected laser and light-based treatments may be considered where suitable.
These may include:
Pico Laser
Pico laser technology delivers ultra-short pulses to fragment pigment into smaller particles. It allows for controlled targeting of pigmentation with minimal heat, which may be beneficial for hormonally triggered pigmentation.
Pro Yellow Laser
Pro Yellow Laser utilises a 577 nm wavelength that targets both pigmentation and vascular components. This may be suitable for certain types of melasma, particularly where redness or inflammation is present.
BroadBand Light (BBL)
BBL delivers light energy to target superficial pigmentation and support overall skin tone improvement. It may be considered in selected cases based on skin type and pigmentation pattern.
Digital Peel Laser
Digital Peel Laser is a fractional laser treatment that combines dual wavelengths to support skin renewal and improve pigmentation. It may also help enhance overall skin texture and clarity as part of a comprehensive treatment plan.
Treatment selection is based on individual assessment, as hormonal pigmentation can be sensitive to heat and may require a more gradual and controlled approach.
Not all treatments are suitable during pregnancy or breastfeeding, and medical evaluation is required prior to proceeding.
Supporting Skin Through Hormonal Changes
Pregnancy and perimenopause are natural phases of life, but the skin changes that accompany them can be a concern for many women.
At Healthsprings Laser & Aesthetic Clinic in Singapore, our doctors provide personalised assessment and management plans tailored to each individual’s skin condition and stage of life.
If you are experiencing pigmentation changes and would like further advice, you may consider a consultation to better understand your skin and suitable options.
