DiamondGlow is diamond-tip microdermabrasion with a branded serum pumped in during the same pass. The abrading part is the same technology a generic diamond-tip machine uses: a diamond-grit tip plus vacuum. What the brand adds is a wet, closed system that delivers a named SkinMedica serum onto the freshly abraded skin, a defined protocol, dealer training, and a price that reflects all of that.
No trial has compared DiamondGlow with a generic diamond-tip machine. Nobody has run that study, so there is no measured answer to the question this page exists to ask. There is also no head-to-head trial of DiamondGlow against conventional microdermabrasion, or against anything else.
Both are the same class of FDA device, and it is an exempt class. DiamondGlow is the current name of a platform its manufacturer, Allergan, lists with the FDA as a Class I powered dermabrasion device, product code GFE, 21 CFR 878.4820, exempt from FDA premarket review — the FDA listing still carries the platform's earlier names, SilkPeel and Dermalinfusion. So is every generic microdermabrasion machine. There is no K-number for DiamondGlow, and the manufacturer does not claim one. Its own site describes it plainly as "a general dermabrasion device" that "gently removes the top layer of skin and delivers topical cosmetic serums onto the skin," and states that the Pro-Infusion Serums are intended to meet the FDA's definition of a cosmetic and are "not intended to be drugs that diagnose, treat, cure, or prevent any disease." That is unusually careful language, and it is more accurate than what many clinics say about the machine.
What you are actually buying with the brand is consistency, not a different mechanism. A known serum formula, a documented protocol, single-use tips bought from the manufacturer, published safety information, an adverse event reporting line, and a company large enough to answer the phone are real things and worth something. They are just not the same as evidence that the treatment outperforms a cheaper machine, and no such evidence exists.
DiamondGlow is the rebrand of Dermalinfusion, which began as SilkPeel from Envy Medical. Allergan acquired Envy Medical in March 2019, and the product now sits under the SkinMedica brand inside Allergan Aesthetics, an AbbVie company. The manufacturer's description of the mechanism is that it "simultaneously exfoliates, extracts and infuses the skin with professional strength serums" using "medical grade diamond treatment tips."
Crystal machines propel inert crystals at the skin and vacuum them back. Diamond-tip machines use a fixed diamond-grit wand and vacuum. Some also offer a fluid step. There are roughly 158 device listings under this FDA product code, ranging from large aesthetics companies to imported skin scrubbers and blackhead vacuums.
The tip abrades within a fluid film while suction removes the debris and the used solution, so a chosen serum sits on skin that has just had its outer layer disturbed. That is the whole theory: a briefly more permeable surface plus a formulated solution applied at that moment.
The generic procedure removes surface debris and dead cells and leaves you to apply whatever the clinic stocks afterward. The published depth work shows what controls how much comes off is the crystal flow rate and how long the tip lingers, not the suction number on the display.
No depth measurement has been published for DiamondGlow specifically. The measurements that exist for this technology are for the wet diamond-tip category generally, and they are small: the outer dead layer of facial skin averages about 9.42 microns, and one imaging study of wet diamond-tip treatment in 8 people found it fell to 6.67 microns immediately and rose to 9.75 microns at two weeks.
In 49 people, a single microdermabrasion treatment produced no detectable change in the thickness of the outer dead layer. There are roughly 158 device listings in this product code, tip quality is not standardized across them, and how much comes off depends on the settings, the state of the tip and how long the operator lingers. Nothing about the paperwork sorts a well-maintained clinic machine from an imported skin scrubber.
There is no 510(k) for DiamondGlow, Dermalinfusion or SilkPeel. The device listing sits under Class I, product code GFE, exempt. Allergan Aesthetics does hold genuine Class II clearances for unrelated products, and those clearances belong to those products, not to this one.
Powered dermabrasion devices were exempted from premarket notification in 1998, manual ones in 1994. No microdermabrasion machine has FDA-cleared indications for use, because the category never goes through review.
The largest is 29 women, Fitzpatrick II to VI, 12 weeks, six treatments every two weeks with a growth factor Pro-Infusion Serum, plus the same serum used twice daily at home. Investigator-rated fine lines, smoothness, radiance and hydration all improved significantly. It was prospective, open-label and had no control arm, the authors were affiliated with Allergan Aesthetics and a contract testing company, and the in-office device treatment cannot be separated from 12 weeks of twice-daily home serum.
Around 225 published records, including split-face work on barrier function, a dose study showing three passes did no better than two, and an evidence review concluding microdermabrasion can improve skin contour irregularities and help deliver certain medicines, while its role in pigment problems and acne is limited.
The company's own safety information says typical side effects are "a scratchy, stinging sensation during the treatment and temporary tightness, redness or slight swelling after the treatment," that serious side effects are uncommon, and that rare serious effects include severe skin irritation and allergic reactions. It also says you should not have the treatment if you have compromised skin quality.
Redness is usually back to baseline within a day. Crystal versions spray loose aluminum oxide near the eyes and airway, which is why eye protection is standard, though no eye injury from microdermabrasion crystals has been published. How rough the treatment is depends on the machine, the tip and the person holding it, and none of that is consistent across the long tail of listings in this product code.
That is the schedule the manufacturer-run studies used. No study has tested an interval or a maintenance schedule. There is no reliable published price for DiamondGlow: no professional society reports a fee for it, the manufacturer publishes no list price, and clinic menu prices are commercially set and should not be averaged into a national figure.
Weekly is the most common published interval, commonly six sessions - but on a generic machine the interval is set by whoever owns it. The only citable prices are a consumer survey average of $177 from 90 self-reported reviews, updated June 2023, and $167 from a 2020 professional-society survey, and neither tells you anything about the machine you will actually be treated with.
Three things, and it is worth separating them.
The first is a known formula. Professional serums are not required to carry a consumer ingredient list, so at many clinics you genuinely do not know what is being put on your skin. Allergan publishes what its Pro-Infusion Serums are and states plainly that they are cosmetics rather than drugs. That is more information than most of this market gives you.
The second is a protocol and a distribution model. A branded platform comes with defined settings, defined tips, dealer training and a published adverse event line. The reason that matters is visible in the FDA's own reports: the complaints on file for professional devices in this category include damaged power supplies and exposed wiring, and one report of an operator being lightly shocked. A manufacturer with a service network is a real form of quality control.
The third is a price. And the honest position is that the first two are worth paying something for, while none of it has been shown to produce a better result on your face than a well-maintained generic machine in the hands of a good operator. The comparison has never been run.
Every published study of this device is open-label, uncontrolled and manufacturer-connected, and every one bundles the device with a topical product. That is not an accusation, it is a description of the design. Open-label, uncontrolled studies in aesthetics reliably produce positive results, which is why controls exist.
The practical consequence is specific: in the 29-person study, subjects had six in-office treatments over 12 weeks and also used the same growth factor serum twice a day at home for those 12 weeks. Twelve weeks of a twice-daily serum will change how skin looks on its own. There is no arm of that study that isolates the device.
So the fair reading is that people who had these treatments looked better afterward on investigator-rated scales, and the study cannot tell you which part did it.
There is no reliable published price for DiamondGlow. No professional society tracks it, no government dataset covers it because it is never billed to insurance, and the manufacturer does not publish a treatment price. Clinic menu prices exist, but they are set by the businesses selling the treatment and averaging them would produce a number that looks authoritative and means nothing.
For plain microdermabrasion, the most citable figures are a consumer survey average of $177 from 90 self-reported reviews last updated June 2023, and a professional society figure of $167 from 2020, which was the last year that society reported microdermabrasion separately. Both are weak. A widely quoted $1,829 figure circulating as a microdermabrasion price is a blended average for skin resurfacing procedures generally, including ablative laser, and is not a microdermabrasion price.
Tell your provider about any allergy, including to skincare ingredients, before a serum step is used on abraded skin. The one reported allergic reaction on file involved a serum applied during treatment.
If you get cold sores, say so at booking. Antiviral medicine is started in advance, so it has to be prescribed before the appointment.
Skip either treatment if your skin is currently broken, sunburned or actively inflamed. The manufacturer's own contraindication is compromised skin quality.
Ask what machine is being used, whether the tip is new, and what solution is going onto your skin. If a clinic tells you the machine is FDA cleared or FDA approved, that is not accurate for either device on this page, and it is a reasonable moment to ask what else they have been told by a sales rep.
