5.6 Pigmentation, Growths, and Cancer Red Flags

Pigment vocabulary and red-flag thinking

Melanin is the pigment that gives skin, hair, and eyes much of their color. Melanocytes make melanin, and more active melanocytes produce darker skin. Pigmentation questions may appear in skin physiology, skin analysis, contraindication, and product-selection scenarios. A candidate should know the vocabulary and also understand when a spot is no longer just a cosmetic concern.

Hyperpigmentation means excess pigment or darkening. It may follow sun exposure, inflammation, acne, injury, hormonal influence, or other causes. Hypopigmentation means reduced pigment. Leukoderma describes light patches caused by loss of pigment. Vitiligo is a condition involving loss of pigment in patches, but diagnosis belongs to a medical provider. Chloasma or melasma is often associated with hormonal pigment changes. Lentigines are small pigmented spots often related to sun exposure and age.

Post-inflammatory hyperpigmentation is important in esthetics because irritation can leave darker marks, especially in skin that produces more melanin. This does not mean darker skin cannot receive services. It means the esthetician must choose technique, timing, exfoliation level, heat, and home care carefully. Aggressive picking, excessive exfoliation, and poor sun protection can worsen pigment concerns.

Growths require a different kind of caution. Skin tags, seborrheic keratoses, moles, warts, cysts, and other visible growths may be seen during analysis. Some may be benign, but estheticians should not remove them unless a specific state scope allows a narrow service, and they should not diagnose them. Suspicious growths should be referred to a physician or dermatologist before cosmetic treatment over the area.

A useful red-flag screen is the ABCDE pattern. A stands for asymmetry. B stands for border irregularity. C stands for color variation. D stands for diameter or size concern. E stands for evolution, meaning change in size, shape, color, elevation, symptoms, bleeding, itching, or healing pattern. Not every suspicious lesion follows a perfect rule, so any changing, bleeding, nonhealing, or unusual lesion deserves referral.

The exam may ask what to do when a client wants a dark spot lightened. If the spot is stable and non-suspicious, the esthetician can discuss cosmetic brightening within scope, daily sunscreen, and realistic expectations. If the spot is irregular, changing, bleeding, crusting, painful, or unlike the client's other marks, the correct action is referral before treatment. Brightening products are not a substitute for medical evaluation.

Sun exposure is a major pigment and cancer-risk concept. Estheticians should reinforce broad sun-protection habits within their role, especially after exfoliation and pigment-focused services. However, do not claim to screen, diagnose, or rule out skin cancer. The professional role is to notice concerning signs, document objectively, avoid treating suspicious tissue, and direct the client to appropriate medical care.

A helpful exam habit is to separate stable pigment concerns from suspicious lesions. Routine product selection belongs with stable cosmetic concerns, while asymmetry, change, bleeding, itching, or nonhealing tissue shifts the answer toward referral.
