Intralesional Injections Carlsbad
medication delivered straight into the lesion

A small amount of medication — most often a dilute corticosteroid — injected directly into a lesion rather than applied on top of it or taken by mouth. Delivering it into the lesion means a high local concentration exactly where it is needed and very little reaching the rest of the body, which is why it works quickly and why systemic side effects are uncommon.

Usually within 24 to 48 hours, and it is genuinely one of the most satisfying things we do. A deep, painful, inflamed nodule that would otherwise take one to three weeks to settle typically flattens and stops hurting within a day or two. Just as importantly, resolving it quickly reduces the chance it leaves a scar. If you have an event and a cyst has appeared, this is the treatment to ask about.

It falls within our medical dermatology range of $150 to $375 at Glow Theory in Carlsbad, depending on the number of lesions treated and the complexity of the visit. Several lesions can usually be treated in one appointment.

Briefly. The needle is very fine and the volume injected is small, but injecting into a lesion — particularly an inflamed one — creates pressure that stings for a few seconds. It is short-lived, and for an acutely painful cyst the relief that follows within a day usually makes it an easy trade.

Yes, and this is the risk worth understanding. Corticosteroid injected into skin can cause local atrophy — a small depression or dimple at the injection site — because it thins the tissue there. It is dose and technique dependent, which is why concentration is kept as low as will work, and it usually resolves over several months as the tissue recovers. It is uncommon at appropriate doses but it is not rare enough to leave unmentioned.

It can. Hypopigmentation at or around the injection site is a recognised effect, and it is more noticeable and longer-lasting in deeper skin tones. Sometimes it tracks a little way from the injection point along the lymphatics. It generally improves over months but may not resolve completely. We take skin tone into account when deciding concentration and whether to treat at all, and we will raise it before injecting rather than afterwards.

Several. Keloids are treated at roughly four to six week intervals, and meaningful flattening usually takes three to six sessions or more. Some are stubborn enough to need combination approaches. Anyone suggesting a keloid will resolve in one injection is overstating — this is a course, and knowing that at the start makes it far easier to persist with.

A hypertrophic scar is raised but stays within the boundary of the original wound, and often improves gradually on its own. A keloid extends beyond the original injury into surrounding normal skin, does not resolve spontaneously, and is more likely to recur after treatment. They respond to the same injections, but the outlook and the expected number of sessions differ.

For alopecia areata — the patchy, well-defined type caused by an immune response against the follicle — injected corticosteroid can prompt regrowth over several weeks, and it is a well-established treatment. It does not treat male or female pattern hair loss, which is an entirely different process. Establishing which you have is the first step, because the treatments have nothing in common.

For an inflamed acne cyst, yes, and it is one of the better reasons to ask. Ideally 48 to 72 hours before rather than the same morning, so the lesion has time to settle. What we would not do is inject a large dose into a prominent site right before something important, since a small dent or pale mark is a possibility worth avoiding at that moment.

Within limits. Because so little reaches the bloodstream, systemic effects are uncommon — but repeated injections into the same site increase the risk of local atrophy and pigment change. That is why intervals are spaced, concentration is kept as low as effective, and we track what has been treated. Frequent injections for recurring acne cysts is a signal that the underlying acne needs better control rather than more injections.

It is avoided over active skin infection, in uncontrolled diabetes where healing and glucose control may be affected, and where there is a known hypersensitivity to the preparation. It is used cautiously in pregnancy. Tell us about your medical history — particularly diabetes, since even small doses can occasionally affect blood sugar.

Frequently. Keloids often respond better to injection combined with other approaches, and inflamed cysts are commonly injected first and excised later once settled. For acne, injections manage individual lesions while a proper medical plan addresses why they keep appearing — the two are complementary rather than alternatives.

Then the injections are treating symptoms rather than the problem, and the useful conversation is about the acne itself. Repeatedly injecting recurring nodules is a reasonable short-term measure and a poor long-term plan. We would look at a proper medical routine, and where the acne is severe or cystic that may mean escalating treatment rather than continuing to manage each lesion as it arrives.

Softening and reduced itching often come first, within a couple of weeks. Visible flattening builds across sessions over months rather than appearing after one. Colour usually improves last. Scars treated earlier in their life generally respond better than long-established ones.
