A patient came in last month convinced she had a stubborn case of eczema. She'd been buying creams off the pharmacy shelf for almost a year. The patch on her shin wasn't eczema at all, and a quick conversation plus a coordinated topical treatment and dermatology referral got her the right diagnosis within two weeks.
That story repeats itself more than you'd think. Skin is the body's largest organ, and it's the one we can actually see, yet most of us aren't sure what to do when something on it looks off. Here in Los Angeles, where the sun does real work on our skin year-round, I spend a fair amount of time helping patients sort the harmless from the worth-a-closer-look.
What can a primary care doctor treat without a dermatologist?
Quite a bit, actually. A lot of everyday skin complaints respond well to first-line topical therapy I can start right in the office. Think mild acne, contact rashes, simple fungal infections, dry irritated patches, and minor flare-ups of conditions you already have a handle on.
In my practice I often start with a topical — a medicated cream, gel, or ointment — and give it a real chance to work. Many skin issues just need the right product used the right way for a few weeks. I'll show you how much to apply and where, because the most common reason a cream "fails" is that it wasn't used long enough or thickly enough.
If things improve, wonderful. We saved you a specialist visit and a wait. If they don't, that tells me something useful too, and we move to the next step.
When should I see a dermatologist instead?
Some skin problems deserve a specialist from the start, and I'd rather send you early than have you wait. I look for a referral when a spot is changing, growing, bleeding, or not healing. New or shifting moles always get attention. So does any rash that's spreading fast, painful, or coming with fever.
Other reasons I reach for a referral:
- A mole or freckle that's changing color, shape, or size
- Acne or rosacea that hasn't budged after a solid trial of topical treatment
- Suspicious growths, sores that won't heal, or anything that bleeds easily
- Widespread psoriasis or eczema that's affecting your sleep or daily life
- Skin changes tied to a larger health picture, like new patches alongside a chronic condition
Many of these overlap with the broader skin conditions I help patients manage, and the goal is always the same: get you in front of the right person at the right time.
How does a coordinated dermatology referral actually work?
It means you're not left to figure it out alone. When I refer, I'm sending a colleague including Cedars-Sinai specialist network a clear summary of what I've already seen and tried, so you don't start from zero in the exam room.
That hand-off matters. A good specialist referral and coordination shortens the path to a diagnosis and keeps everyone on the same page about your history, your medications, and what's already been ruled out. I'll also follow up after your visit so the plan loops back into your overall care rather than living in a separate silo.
One thing I'll gently push back on: the urge to self-diagnose from photos online. Skin cancers can masquerade as ordinary spots, and harmless things can look alarming. A trained eye, and sometimes a biopsy, is how we know for sure.
Can I prevent skin problems in the first place?
A lot of the time, yes — and prevention is where Los Angeles patients can make the biggest difference. Daily sunscreen, even on overcast days, is the single most protective habit I recommend. Our UV exposure here is no joke.
Beyond that, I encourage regular skin self-checks. Get to know your own moles and freckles so you notice when one starts behaving differently. Keeping your skin moisturized, staying hydrated, and managing stress all help too, since flares of eczema and psoriasis often track with what's happening in the rest of your body. This kind of watchfulness fits naturally into the rhythm of ongoing preventative medicine.
If something on your skin has been nagging at you — a spot that's changed, a rash that won't quit, or a mole you keep glancing at in the mirror — don't sit on it. Reach out and let's take a look together. Sometimes it's nothing, sometimes it's worth a specialist, and either way you'll leave with a real answer instead of another guess.
