Someone notices something new on their skin and goes wherever the website looks nicest. Sometimes that works; sometimes it ends in a month of treatments that did nothing, because the problem was never cosmetic. The rule that saves that month is simple, and you can apply it yourself.
What a dermatologist does
Dermatology is a branch of medicine: diagnosing, treating and preventing diseases of skin, hair and nails. The doctor examines you, often under magnification, orders tests where needed, reaches a diagnosis and treats it. The output of that work is healthy skin, not smooth skin.
Go there with anything that is behaving actively
- It itches, hurts, burns or weeps
- It flakes, crusts or cracks
- Rashes of unclear origin, particularly spreading ones
- A reaction to a new product, medication or food
- Moles and growths: changed, growing, bleeding, itching
- Hair loss, changes in the nails
What a cosmetologist does
A cosmetologist works on the appearance of healthy skin: quality, hydration, density, tone, changes that come with age. Lines, dull tone, lost volume, pigment, acne scarring, unwanted hair — all theirs.
One detail matters: a good share of cosmetology is medical work, carried out by medically qualified staff. The “non-doctor” part of cosmetology is skincare, not injections and devices.
Where the line falls in practice
| What you came with | Who to see |
|---|---|
| A rash that itches or spreads | Dermatologist |
| Marks and texture left by acne that has passed | Cosmetologist |
| A mole has changed, or something new appeared | Dermatologist |
| Sun-related dark spots | Cosmetologist — the spot is still examined first |
| Flaking and tightness that skincare does not fix | Dermatologist |
| Dryness and dehydration in healthy skin | Cosmetologist |
| Hair loss | Dermatologist or trichologist |
| Lines, lost volume, jawline | Cosmetologist |
Why the order matters more than the choice
Cosmetology on unwell skin does nothing at best and harm at worst. A peel on inflamed skin, a device treatment during a dermatitis flare, injections with an active infection — all reasons a conscientious doctor will decline and send you to be treated first.
A good sign in either of them
A doctor who tells you at the examination “this is not mine, you need a colleague” is doing more for you than one who finds something to prescribe regardless. Passing a patient to a colleague is not a lost client — it is ordinary medical practice.
Common questions
How is a dermatologist different from a cosmetologist?
A dermatologist is a doctor who diagnoses and treats diseases of skin, hair and nails. A cosmetologist works on the appearance of healthy skin: quality, tone, changes that come with age. One answers “what is happening to me”, the other “how do we improve this”. You often need both — in that order.
What definitely goes to a dermatologist?
Anything that itches, hurts, weeps, flakes, crusts, spreads or grows: rashes of unclear origin, dermatitis, reactions to products or medication, changing moles, any new growths, hair and nail problems. Cosmetic procedures on inflamed or diseased skin can make things worse.
What if it is just spots?
Acne is a condition, not a cosmetic flaw. Mild forms are managed by a cosmetologist; moderate and severe ones need a doctor and systemic treatment. Persistent breakouts often trace back to hormones or gut health, too. A good cosmetologist will refer you on if aesthetics alone will not settle it.
Can a cosmetologist remove a mole?
No. Any skin growth is examined by a dermatologist first, including under magnification. Removing a lesion without establishing what it is would be wrong, and no conscientious practitioner will do it. What to do about your particular mole is decided at an examination — not by an article and not from a photo in a messenger.
Can I see both?
Yes, and it is often the shortest route. RE/FACE has both a dermatologist and a cosmetologist, ₽3,000 each. If the examination shows the problem belongs to the other one, the doctor will say so and refer you rather than prescribing something for the sake of it.
