What Is Micro Infusion? How It Works, Cost and Who It's For

Micro infusion is shallow microneedling with a serum put on the skin in the same step. A stamp of tiny needles makes small channels, and the serum goes on during or right after. "Micro infusion" is a marketing name. The FDA treats these tools as microneedling devices¹. At home it costs about $12 to $50 a session.

Key points

• Micro infusion is microneedling plus a serum. The FDA groups the tools with microneedling devices¹.
• The FDA says microneedling devices "are not approved for delivery of cosmetics" or topical medicines¹.
• At-home kits cost about $12 to $50 a session on 24 Oct 2026. One clinic lists it as a $75 add-on⁶.
• Reviews of microneedling in general show high satisfaction and few side effects, but the studies vary in quality^2,4,5.
• Skip it if you have an active cold sore, took isotretinoin in the last 6 months, or are pregnant or breastfeeding¹.

What is micro infusion?

Micro infusion uses a small stamp or pen with very short, fine needles. You press it on the skin, and it makes tiny holes in the top layer. A serum goes on in the same session. Some kits put the serum inside the stamp so it flows out as you press. Others have you spread the serum first.

Brands sell this as a way to help serum ingredients reach deeper into the skin. That is a brand claim. The FDA page on microneedling says the devices are not approved for delivering cosmetics into the skin. It also says the risks of combining microneedling with other products "are not known"¹.

The FDA has "legally authorized microneedling devices to improve the appearance of facial acne scars, facial wrinkles, and abdominal scars in patients aged 22 years or older"¹. That covers certain cleared devices, not every product sold online.

How micro infusion works

The steps are much the same across brands:

1. Clean the skin.
2. Mix or load the serum, if the kit asks you to.
3. Press the stamp over the face in small sections.
4. Leave the serum on, and follow the aftercare rules.

The needles in home kits are short. Brands usually state their depth in fractions of a millimeter. Shallow needles do not reach as deep as clinic microneedling. A 2026 review rated the evidence for home microneedling as low quality⁵.

Aftercare matters. Brands commonly tell you to avoid makeup, strong acids and retinol for a day or more, and to wear sunscreen⁹. For timing between sessions, see how often to do micro infusion. If you also use red light, read LED mask after microneedling.

Micro infusion vs microneedling

The difference is mostly in the marketing. Microneedling is the method: needles make small channels in the skin. Micro infusion is microneedling sold together with a serum, usually with shallower needles. A clinic may also use the word for a treatment that adds Botox or fillers to the serum⁷. We cover the details in micro infusion vs microneedling.

At home vs in a clinic

Notes. Home prices from the kit table below, checked 24 Oct 2026. Clinic price from ICON Dermatology, North Bethesda, Maryland⁶.

At ICON Dermatology in North Bethesda, Maryland, microinfusion is listed as a $75 add-on "to any treatment"⁶. Its Boost Infusion add-on is $100, or $150 with Botox⁶. The clinic says it uses the HydraNeedle device, with 20 gold-plated needles, and works at "a precise 600-micron depth"⁷. That is 0.6 mm.

We found no at-home micro-infusion stamp kit with an FDA 510(k) or De Novo record when we searched openFDA on 24 Oct 2026⁸.

What micro infusion costs

Most home kits sell a set number of sessions. To get the price per session, divide the kit price by the sessions it holds. For example, a $169 kit with 6 sessions works out to $169 / 6 = $28.17 a session¹².

Clinic treatments are one session at a time. At ICON's add-on price, 6 sessions would cost 6 x $75 = $450, before the main treatment it is added to⁶. Prices differ by city, so call your own clinic.

Does micro infusion work?

There is no good study of any named home micro infusion kit that we could find. The research is on microneedling in general.

• Satisfaction. A 2025 review of 21 studies with 723 patients found 83% were satisfied with microneedling for facial aging². The authors said "MN is associated with high patient satisfaction and low rates of adverse events"². They also said "the lack of standardized measures for esthetic outcomes warrants continued research"².
• Safety. A 2021 review of 51 articles and 1,029 patients called microneedling a "relatively safe procedure with minimal adverse effects"⁴.
• Home devices. A 2026 review of home skin devices said home microneedling is "supported by low-quality evidence (Level D) and associated with infectious complications"⁵. It rated home LED and radiofrequency devices higher, at Level B⁵.

So clinic microneedling has some evidence behind it. Home kits with very short needles have much less. What a brand says about its serum is a brand claim.

How long do results last?

No study we found measures how long micro infusion results last. Claims vary widely. One home kit brand says its glow "lasts for about 7–14 days" after one session⁹. ICON says its clinic version lasts "approximately 3-4 months", but that treatment can include Botox⁷. Home brands suggest repeat sessions every 1 to 4 weeks. The FDA notes that "you may need more than one procedure"¹.

Side effects and who should skip it

Side effects in studies are mostly mild. In the 2025 review, redness was the most common, at 6.8%, followed by scaling at 1.7% and burning at 1.5%². A 2025 review found 15 people across 13 studies with granulomas, a rare reaction that can be hard to treat³. Motorized pens and topical vitamin C were linked to some cases³.

The FDA lists common risks such as dryness, redness, itching, peeling, bruising and bleeding¹. Less common risks include skin color changes, infection and cold sores coming back¹. It also says "re-use of the needle cartridge is unsafe"¹.

The FDA says not to use a microneedling device if you¹:

• have an active cold sore, infection or rash
• used isotretinoin in the last 6 months
• form keloid scars
• are pregnant or breastfeeding
• have a bleeding disorder
• have a tan or will be in the sun in the next two weeks

It also warns that people with darker skin types may get darker or lighter patches¹.

When to see a dermatologist

See a dermatologist before you start if you have acne, rosacea, eczema, keloids or a skin condition you are treating. See one first if you take blood thinners or have darker skin and worry about color changes. Stop and get checked if you have redness or swelling that grows after 2 days, pus, fever, bumps that do not go away, or new dark or light patches^1,3.
