Body Hyperpigmentation: Why the Same Approach as Your Face Doesn't Always Work
Most pigmentation content focuses on the face — melasma on the cheeks, post-acne marks, sun damage on the forehead. But body hyperpigmentation is just as common and often more persistent, because the skin on the body is structurally different from facial skin in ways that affect how it responds to treatment.
How body skin differs from facial skin
Body skin is generally thicker, has fewer sebaceous glands, produces less natural moisturisation, and has a slower cell turnover rate than facial skin. These differences have direct implications for pigmentation:
Slower absorption. The thicker stratum corneum on the body means that active ingredients penetrate more slowly and less efficiently. OTC concentrations that might have modest effect on facial skin have even less impact on body skin.
Slower cell turnover. The natural shedding process that helps fade pigmentation on the face is slower on the body — meaning hyperpigmented cells take longer to shed and marks persist longer.
Different triggers. Body pigmentation is often driven by friction, pressure, and hormonal factors rather than purely UV and acne-related causes. These mechanical triggers require different management alongside topical treatment.
Common body hyperpigmentation patterns
Joint darkening (elbows, knees). Friction-driven melanin overproduction — the skin's protective response to repeated mechanical stress. Read more about dark elbows and knees specifically.
Underarm darkening. Friction from clothing and shaving, deodorant-related irritation, and hormonal influences. A common concern with the same prescription treatment pathway as other body PIH.
Inner thigh and groin darkening. Friction, moisture, and in some cases acanthosis nigricans associated with insulin resistance. The velvety texture of acanthosis nigricans warrants medical evaluation.
Post-inflammatory body marks. Dark marks from insect bites, folliculitis, ingrown hairs, and skin injuries. The same PIH mechanism as post-acne facial marks, but slower to fade on body skin.
Hormonal body pigmentation. During pregnancy, PCOS, perimenopause, and while using hormonal contraceptives, melanocyte activity can increase throughout the body — producing diffuse darkening in friction-prone areas and skin folds.
What prescription treatment looks like for body hyperpigmentation
The same actives that treat facial pigmentation are effective for body pigmentation — tranexamic acid, azelaic acid, kojic acid, and tretinoin — but their use on the body requires clinical consideration of the thicker skin barrier and the specific triggers involved.
At Laevo, body pigmentation concerns are assessed through the Pigment Modulation add-on in combination with the Core Formula. The prescription approach:
Addresses melanin overproduction at the enzymatic level — not just fading existing pigment at the surface
Includes a retinoid base to accelerate the slower cell turnover of body skin
Can be formulated for body application with appropriate vehicle considerations
Lifestyle factors that matter for body pigmentation
Reduce friction. Wearing loose-fitting clothing, using knee pads for floor activities, avoiding tight synthetic fabrics in friction-prone areas — reducing the primary mechanical trigger slows new pigmentation formation.
Regular exfoliation. Body skin benefits more from regular exfoliation than facial skin because its slower cell turnover allows dead cell accumulation to make existing pigmentation more prominent. Gentle exfoliation 2–3 times weekly is appropriate.
Daily moisturisation. Dry skin appears darker. Consistent ceramide-rich body moisturisation improves the surface appearance and reduces the friction effect by keeping skin supple.
SPF on exposed areas. UV exposure amplifies all forms of body hyperpigmentation. Areas regularly exposed to sun require SPF protection for any topical treatment to work optimally.
When body darkening may indicate something else
If darkening on the body has a distinct velvety or rough texture — particularly in skin folds, armpits, or around the neck — this pattern may indicate acanthosis nigricans, which can be associated with insulin resistance, diabetes, PCOS, or thyroid disorders. The Laevo assessment screens for this and will flag where a broader medical evaluation is warranted.
The Laevo assessment covers body pigmentation concerns alongside facial concerns.

Assessment fee applies. Prescription required — not all applicants will be approved. Body darkening with velvety texture should be evaluated by a physician. Individual results vary. This article is for informational purposes only and does not constitute medical advice.
