A Type IV Client, a Home Acid Pad, and Ten Days Until the Wedding
A 34-year-old woman with Fitzpatrick type IV skin comes for her first facial. On the intake form she lists tretinoin 0.05% cream nightly for eight months, a 10% ascorbic acid serum each morning, and a drugstore "30% glycolic" peel pad she used two nights ago. She says the pads "tingled a lot" and left her cheeks pink and slightly rough to the touch. Under magnification you see diffuse brown post-inflammatory hyperpigmentation on both cheeks, several closed comedones along the jawline, and faint telangiectasia across the nose and medial cheeks that she says "flares" after wine and hot yoga. She wants "the strongest peel you have" to clear the dark spots before a wedding in ten days, and she asks whether the peel can be done today so the redness has time to fade.
1. Separate this client's skin type from her skin conditions, and explain why the distinction changes the treatment plan.
Read the worked answer
Skin type is genetic and describes how the skin behaves, particularly melanin reactivity. Fitzpatrick IV tans easily and carries a moderate-to-high risk of post-inflammatory hyperpigmentation after any injury or inflammation. Type does not change with treatment.
Conditions are the findings, and they are treatable:
- PIH on both cheeks - a sequela of prior inflammation and a warning that further inflammation will darken her.
- Closed comedones at the jaw - follicular congestion, possibly cosmetic or hormonal.
- Telangiectasia with heat and alcohol triggers - vascular, consistent with rosacea. This is not a pigmentation problem and will not respond to a pigmentation peel.
- Barrier impairment - stinging, roughness and erythema two days after a strong home acid layered on nightly tretinoin.
Why it matters. Type dictates risk and product selection: lower-potency agents (mandelic or lactic rather than a strong glycolic), conservative timing, and explicit PIH consent. Conditions dictate whether you treat at all and which condition you target first. Chasing the pigment while ignoring the vascular and barrier findings is exactly how estheticians produce the outcome the client fears: more brown and more red.
2. Should you exfoliate today? Justify your decision using the specific findings.

No - not today, and not with a strong acid.
- The barrier is already compromised. Burning with an OTC 30% pad, persistent erythema, roughness and nightly tretinoin on top of it. A professional acid now raises the odds of irritant dermatitis and, in type IV skin, PIH.
- The vascular pattern suggests rosacea. Heat, steam, strong acids and vigorous massage are recognized flare triggers; a peel is the wrong tool for telangiectasia.
- The timeline is the hazard. Ten days is long enough for a peel reaction to become visible and far too short for PIH to fade. A peel today could leave her more pigmented on the wedding day than she is now.
What to do instead. Gentle cleanser, no scrubbing, no steam or hot towels, a calming mask, barrier cream, mineral SPF 30+, and no extractions beyond the superficial. Home care: stop the acid pad and the tretinoin for 5–7 days, bland moisturizer, sunscreen. Reassess in two weeks.
When to peel. After the barrier settles, with a pre-peel regimen, a patch test, and a series of superficial peels at 2–4 week intervals. Document the refusal, the reasoning, and the pre-care instructions given.
3. Outline the next ten days and the expectation-setting conversation, including what you must not promise.
Read the worked answer
Days 1–7. Barrier repair: gentle cleanser, ceramide moisturizer, mineral SPF 30+ reapplied during the day. No acids, no retinoid, no scrubs, no waxing, no dermabrasion, no sauna or hot yoga if she can avoid it. Days 7–10. Introduce nothing new. If she wants visible improvement for the event, use hydration and a makeup plan rather than an acid. After the event. Restart tretinoin gradually every other night; book a consult for a superficial peel series, holding the retinoid 5–7 days before each peel per your protocol.
The conversation. Separate the two problems. Brown marks fade over weeks to months; the redness is vascular and peels will not fix it - that is a referral. Be direct that type IV skin pigmenting after treatment is a known, consented risk, and that nightly tretinoin plus a home 30% pad is the likely cause of her current irritation.
Do not promise: clearance by the wedding, that a peel "cannot" darken her, or that one treatment fixes both cheeks. A realistic frame is gradual improvement across a series, with daily sunscreen as the rate-limiting step.
Paperwork. Consent listing PIH risk, baseline photos with permission, and a note that treatment was deferred today with the reason.
