What it is
Sebum comes from sebaceous glands attached to every follicle on your face, densest across the nose, forehead and chin. Output is set mostly by androgen signal: dihydrotestosterone (DHT) binds receptors on the gland's sebocytes and turns production up. Your baseline is genetic; heat, humidity and hormone swings move it around the edges. No cleanser reaches the gland, so scrubbing harder strips the surface lipids your barrier needs while output continues unchanged underneath.
Two approaches actually lower sebum: block the androgen signal at the gland, or shrink the gland itself. Clascoterone 1% cream is the first topical androgen-receptor blocker, works in men as well as women, and showed clear treatment effect in 1,421 phase 3 participants. Spironolactone tablets blunt androgen signal body-wide, for women only, with full effect taking up to 6 months. Isotretinoin shrinks sebaceous glands directly; at low dose it is the heavy machinery, and oil usually climbs back after stopping.
Oil is also why pores read large: a filled follicle stretches and catches light, and sebum feeds the bacteria involved in breakouts. Retinoids help the clogged-pore side by normalizing how follicle cells shed, and in a 22-patient series, RF microneedling improved a six-grade photographic pore score from 3.55 to 2.59 over 3 sessions. What does not work: alcohol toners, aggressive scrubs and skipping moisturizer, which damage the barrier without touching the gland.
What you may be noticing
- Shine returning within a couple of hours of washing
- Sunscreen or makeup sliding off by midday
- Visible pores through the T-zone that look larger by evening
- A tight, stripped feeling after harsh cleansers while the shine still comes back
- Hair at the hairline getting oily on the same schedule as your face
- Frequent small breakouts where the oil is heaviest
How we approach it
- 1
Photos and intake, online
You upload photos and complete a structured intake covering hormones, medications and what you have already tried.
- 2
Phone consult
You talk through the pattern, your history and your goals with the practice by phone.
- 3
Written plan, exact prices
Dr. Mueller reviews everything and you get options in writing, and for oil the usual opening move is a prescription, not a machine.
- 4
Prescriptions, fully online
California law allows non-controlled prescriptions by telehealth, so clascoterone, spironolactone or a retinoid can begin without an office trip.
- 5
In-person exam only if devices enter the plan
If you later add RF microneedling for pores, California requires a synchronous in-person exam first, folded into that visit at $0.
The evidence
- Clascoterone 1% pooled phase 3 data, 1,421 participants: treatment success 19.8% versus 7.8% with vehicle at week 12 (ncbi.nlm.nih.gov/books/NBK616783)
- AAD 2024 acne guideline: conditional recommendations for clascoterone and spironolactone, with cost and evidence-certainty caveats rather than safety alarms (pubmed.ncbi.nlm.nih.gov/38300170)
- Spironolactone monitoring: 1,802 potassium measurements in healthy young women found mild hyperkalemia in 0.72% versus 0.76% at baseline (AAD 2024 guidance)
- RF microneedling for enlarged pores: photographic pore grade improved 3.55 to 2.59 over 3 sessions in 22 patients (pubmed.ncbi.nlm.nih.gov/38609686)
Straight answers
- Can oily skin be fixed permanently?
- Mostly no: gland density and androgen sensitivity are genetic, topicals and spironolactone work while you use them, and isotretinoin is the one tool that remodels the glands themselves, with some of the reduction persisting and some returning after the course.
- What does it cost?
- A prescription visit is $79, follow-ups are $39, and isotretinoin management is $49 per month; every figure is itemized on the pricing page and nothing is added at checkout.
- I'm male. Is there anything besides isotretinoin for me?
- Yes: clascoterone 1% cream blocks androgen receptors locally in the skin, which is why it can be used in men, unlike spironolactone, which is oral, body-wide and prescribed to women only.
- Does oily skin mean I will break out?
- Not by itself; sebum is one input among several (follicle shedding, bacteria, inflammation), which is why the intake asks about breakouts separately and why a plan may address both at once.
- Would isotretinoin just for oil be reasonable?
- Sometimes, at low dose, and that is a physician's call after your intake: iPLEDGE enrollment is mandatory, pregnancy is absolutely prohibited during treatment, dry lips and skin are near-universal, and management here is $49 per month.
- Should I drop moisturizer since I'm already oily?
- No: sebum is not a moisturizer, and a stripped barrier reads as irritation, so a light non-comedogenic moisturizer stays in the routine while a prescription addresses output.
