The Lightening Cream
Ngozi, 29, Fitzpatrick IV, visits a skin-care studio in Abuja with slate-grey patches on both cheeks and temples, thinning shiny skin and fine visible vessels. She has used a 'toning' cream bought from a market stall twice daily for 14 months; the label lists hydroquinone 4%, and she also uses an unlabelled 'triple-action' tube a friend brought from abroad. She wants a 'strong organic fruit-acid peel' to lift the darkness before her sister's wedding in three weeks. She says the cream 'worked at first' but the darkness has become darker and ashier. She has no history of asthma, eczema or drug allergy, is not pregnant and takes no medication. The studio offers glycolic 70% peels and a vitamin C facial. Ngozi has already paid a deposit and says she cannot afford a dermatologist.
1. What is the most likely explanation for the slate-grey patches and thin skin, and why is a 70% glycolic peel unsafe here?

The combination points to exogenous ochronosis from prolonged hydroquinone use, which is a known risk in darker skin when a strong hydroquinone product is used for many months, especially without medical supervision. The thinning, shininess and visible vessels suggest steroid-induced atrophy from the unlabelled 'triple-action' cream, which may also contain tretinoin or mercury. A 70% glycolic peel is unsafe because the barrier is already compromised and the skin is atrophic. Acid penetration will be uneven, the risk of post-inflammatory hyperpigmentation is high in Fitzpatrick IV skin, and poor wound healing can lead to scarring and infection. Peeling cannot remove ochronosis, which is deposited in the dermis. The correct action is to stop the creams and refer for dermatological assessment, not to increase the chemical insult.

Stop all lightening products today, including the unlabelled tube. Switch to a gentle fragrance-free cleanser, a simple moisturiser and broad-spectrum SPF 50 every morning; sun exposure will deepen the pigmentation. Do not scrub, wax, thread or peel the area. Refer her to a dermatologist or a doctor at a general hospital, and explain that the referral is not an upsell but the safe route. Be honest about timing: three weeks is not enough for ochronosis or atrophy to resolve, and any aggressive attempt to speed it up risks making the skin worse. Offer a patch-tested camouflage plan for the wedding and credit or refund the peel deposit because the service is contraindicated. Record the product names, duration, observed signs, advice given and referral in her file.
3. She insists on looking even for the wedding. Describe a safe camouflage approach.

Patch test any new product on a small area behind the ear or on the jaw 24-48 hours before the event, even though the skin is compromised; use a minimal quantity and read the site carefully. For slate-grey patches on Fitzpatrick IV skin, a peach or orange colour corrector applied thinly under a lightweight mineral foundation can neutralise the ashiness better than a heavier concealer. Build in thin layers, avoid occlusive or heavily fragranced products, and set only where needed with a fine powder. Keep the rest of the makeup simple so the corrected areas do not look different in texture. Give written removal advice: gentle cleanser, no wipes with alcohol, no scrubbing. Explain that camouflage is cosmetic and does not treat the underlying problem, and that the dermatology referral still stands.
