Skin pigmentation is one of the most common concerns I encounter in both clinical practice and professional education, and also one of the most misunderstood. As skin ages, pigmentation can become more frequent, more persistent, and more challenging to treat safely.
Understanding the type of pigmentation, why it occurs, and how to manage it correctly is essential for achieving long-term, healthy skin results at any age.
What Is Skin Pigmentation?
Skin pigmentation refers to areas of skin that appear darker than the surrounding tissue due to an overproduction of melanin, the pigment responsible for skin colour. As we age, the skin’s ability to regulate melanin becomes less stable, increasing the likelihood of uneven skin tone, dark patches, and discoloration.
Pigmentation is influenced by UV exposure, hormones, inflammation, genetics, lifestyle, and skin ageing processes.
Common Types of Pigmentation in Ageing Skin
1. Sun Spots (Solar Lentigines)
Often referred to as age spots or liver spots, solar lentigines are flat brown or tan patches caused by cumulative sun exposure over time.
Common areas:
Face.
Hands.
Chest.
Shoulders.
Key cause: Long-term UV damage.
Typical onset: Age 40+
These are a visible marker of photo-ageing and increase with lifelong sun exposure.
2. Melasma
Melasma presents as symmetrical brown or grey-brown patches, commonly affecting the cheeks, forehead, upper lip, and jawline.
Common triggers include:
Hormonal changes (pregnancy, contraception, perimenopause, menopause).
UV and heat exposure.
Genetics.
Melasma is chronic and relapsing, meaning it requires ongoing management rather than aggressive short-term treatments.
3. Post-Inflammatory Hyperpigmentation (PIH)
PIH develops after skin trauma or inflammation such as:
Acne.
Eczema.
Aesthetic treatments.
Injury or over-exfoliation.
More common in:
Deeper skin tones.
Acne-prone skin.
Sensitised or over-treated skin.
Incorrect treatment can worsen PIH, making professional guidance essential.
During perimenopause and menopause, declining oestrogen levels affect:
Skin repair.
Barrier function.
Melanin regulation.
This often results in pigmentation that is more stubborn, unpredictable, and sensitive to treatment.
Additional contributing factors include:
Increased skin sensitivity.
Slower healing response.
Thinner epidermis.
Why Pigmentation Becomes Harder to Treat With Age
As skin matures:
Cell turnover slows.
Inflammation increases.
Barrier function weakens.
Healing processes decline.
This causes pigmentation to sit deeper in the skin, respond more slowly to treatment, and relapse more easily without correct maintenance.
Pigmentation Treatments: What Actually Works
Professional Treatments (When Appropriate)
Customised chemical peels.
Medical-grade LED light therapy.
Microneedling (with strict protocols).
Prescription depigmenting agents (under medical supervision).
Cryotherapy.
Certain laser therapy protocols.
⚠️ Stronger is not better. Overly aggressive treatments can worsen pigmentation, especially in hormonally fragile or sensitised skin. Always seek professional advice and ensure GP advice has been provided to ensure maximum safety prior to any removal treatments.
Homecare Products That Support Pigmentation Correction
Clinically proven ingredients include:
Vitamin C – antioxidant and brightening support.
Niacinamide – reduces inflammation and supports barrier repair.
Azelaic acid – excellent for hormonal and inflammatory pigmentation.
Retinoids – age-appropriate and well tolerated.
Alpha arbutin & tranexamic acid – targeted pigment regulation.
Consistency always outweighs product strength and remember, if you don't protect your skin daily with a good quality SPF then you're not going to achieve the desired results.
The Most Important Step: Sun Protection
No pigmentation treatment will be successful without daily, year-round sun protection.
✔ Broad-spectrum mineral SPF 30–50✔ Applied every morning✔ Reapplied with daylight exposure
UV exposure remains the primary trigger and relapse factor for pigmentation at all ages.
Safety Advice for Clients
Avoid over-exfoliation - it worsens pigmentation.
Do not layer multiple active ingredients without guidance.
Be cautious of online “pigment removal” trends.
Seek professional advice before advanced treatments.
Understand that pigmentation correction is gradual, not instant.
Healthy skin correction requires education, patience, and respect for skin biology.
Final Thoughts From an Industry Expert
Pigmentation is not a surface-level issue - it is influenced by sun exposure, hormones, inflammation, lifestyle, and the ageing process itself. With correct diagnosis, realistic expectations, and a personalised treatment approach, pigmentation can be safely improved at any stage of life.
Education is the foundation of effective skin health, and informed clients always achieve better outcomes.
