Three fairly different things happen behind the same office door. A mole gets checked. A laser gets fired. Somebody gets a facial. All of it counts as dermatology, all of it happens under one roof, and it leaves people unsure what they’re actually booking. This sorts out which is which, who’s qualified to do what, and which door you want.
Key Takeaways
- Dermatology splits three ways: disease, appearance, and upkeep. Most practices run all three.
- The physician handles diagnosis, prescriptions, and anything invasive. A licensed aesthetician takes the surface-level maintenance work.
- Which lane you need usually comes down to one question: is your skin unwell, bothering you, or just overdue for some care?
Ask ten people what a dermatologist does, and you get ten answers. Acne. Botox. Skin cancer. Facials. Each one is fair, which is exactly the problem. The job stretches wider than most people picture, and that’s where the confusion creeps in.
It matters when you’re choosing a dermatologist in North Miami. Some practices lean heavily medical. Others are almost entirely cosmetic. A few run the whole spread, with an aesthetician on staff for the maintenance side. Work out which lane your concern sits in, and you stop booking the wrong appointment.
So, the three kinds of care, who actually performs each one, and how to tell which you need. General information, mind you, not advice for your particular skin.
Three Kinds of Work, One Specialty
The textbook line is that dermatology covers skin, hair, and nails. True, and almost useless. Day to day, the work falls into three buckets that barely resemble one another.
One keeps you healthy. One changes how you look. One holds the results in place. Same specialty on the sign, very different appointments in the room.
The three lanes:
- Medical care for disease and health risk
- Cosmetic care for appearance and aging
- Aesthetic skincare for ongoing maintenance
- Plenty of patients end up using more than one
The Medical Side, Where Skin Is a Health Problem
This is the lane people forget exists. A mole that has changed shape. A rash into its sixth week. Acne leaving marks behind. Eczema, psoriasis, hair loss, nail infections, and the annual skin check nobody enjoys booking.
It’s health care, and insurance often has a say in it. The stakes run highest here too, because catching a melanoma early is a very different story from catching it late.
What the medical side handles:
- Skin cancer screening and mole evaluation
- Acne, rosacea, eczema, and psoriasis
- Rashes, infections, and hair or nail problems
- Anything needing a diagnosis or a prescription
The Cosmetic Side, Where Skin Is Just Bothering You
Nothing in this lane is dangerous, and that’s the entire distinction. Fine lines. Sun spots. Old acne scars. Volume that has quietly shifted. Skin that lost its snap somewhere along the way.
The treatments themselves stay medical, though. Lasers, injectables, prescription-strength peels. These sit at physician level, whatever the marketing around them implies.
Common cosmetic work:
- Botox and dermal fillers
- Laser and energy-based treatments
- Chemical peels and microneedling
- Scar revision and pigment correction
The Aesthetic Side, Which Most People Underrate
Facials, extractions, light peels, a routine somebody actually built for your skin. Low intensity, no downtime, done more often than the other two. It looks like the soft option, and it isn’t.
Done properly, this is what stops the results of everything else from sliding backward. It usually runs through a licensed aesthetician working alongside the physician rather than in place of one.
What the aesthetic side covers:
- Clinical facials and extractions
- Superficial peels and gentle exfoliation
- Guidance on medical-grade skincare
- Upkeep between clinical treatments
Who Is Allowed to Do What
Worth sorting out before you book anything. Your dermatologist diagnoses, prescribes, and performs whatever is invasive or energy-based. The aesthetician works on the surface and cannot diagnose, prescribe, or inject.
Scope rules shift from state to state, and job titles get used loosely out there, so asking outright is entirely reasonable. Anywhere decent will answer without flinching.
Roughly how it divides:
- Diagnosis and prescriptions: physician only
- Injectables and lasers: physician-level work
- Facials and surface care: licensed aesthetician
- Overall responsibility: stays with the physician
Figuring Out Which One You Need
Usually it comes down to one question. Is something actually wrong with your skin, or do you just not like how it looks? Something wrong puts you in medical. Not liking it puts you in cosmetic. Neither one, and you’re in maintenance territory.
Plenty of concerns straddle two lanes at once. Acne is medical, the scarring it leaves is cosmetic, and the routine keeping it calm is aesthetic. One practice covering all three saves a fair amount of running around.
A rough guide:
- Changing mole or a rash that lingers: medical
- Lines, pigment, or scarring: cosmetic
- Dullness and general upkeep: aesthetic
- Acne and its aftermath: often all three
Same Door, Three Different Visits
So what does a dermatologist do? A good deal more than most people picture, and not all of it single-handed. The medical work, the cosmetic procedures, and the ongoing skincare are three separate jobs that happen to share a waiting room. Knowing which is which makes you a far better-informed patient before you ever pick up the phone.
For anyone weighing that locally, a board-certified dermatologist in North Miami such as Dr. Roberta Del Campo at Del Campo Dermatology & Laser Institute can work out which kind of care your skin actually needs. The sensible first step is a consultation, where that gets sorted properly.
