What is the difference between DiamondGlow and HydraFacial?
They are different devices from different companies that overlap on one idea: exfoliate the skin, then get a topical serum onto it.
DiamondGlow is a dermabrasion device from Allergan Aesthetics, an AbbVie company, used with SkinMedica Pro-Infusion Serums; its labeled use is "general dermabrasion of the skin" plus delivering topical cosmetic serums (DiamondGlow).
HydraFacial is the device line from Hydrafacial LLC, whose Syndeo user guide says it is intended to abrade — exfoliate — the upper layers of the skin (HydraFacial).
The mechanical difference is the exfoliation.
Allergan describes DiamondGlow as a "3X1" process — simultaneous exfoliation with diamond tips of varying abrasiveness, extraction by suction, and infusion of a SkinMedica serum — and says its tips give a controlled physical exfoliation, unlike a chemical exfoliation, that removes the top layer of dead skin.
HydraFacial's maker layers steps on top of exfoliation: the company markets its Platinum treatment as seven therapies in one, among them a peel, vortex extraction, booster serums and LED light.
DiamondGlow
- Made by Allergan Aesthetics, an AbbVie company
- Diamond-tip physical exfoliation, suction and a SkinMedica serum at once
- Labeled use: general dermabrasion plus cosmetic serum delivery
HydraFacial
- Made by Hydrafacial LLC
- Intended use: exfoliate the upper layers of the skin
- Platinum tier marketed as seven therapies, including a peel, vortex extraction, boosters and LED
One naming caution: "dermabrasion" here is the light, office-table kind, not surgery.
Cleveland Clinic separates surgical dermabrasion — a procedure that bleeds, crusts and needs about 7 to 14 days before normal activities — from gentle, no-bleeding microdermabrasion; the devices in this guide are the superficial, exfoliating kind.
DiamondGlow marketing has claimed the treatment "supports lymphatic drainage, which helps decrease the appearance of puffiness, support removal of toxins, and brighten skin," and Hydrafacial's marketing says its lymphatic step "Supports skin detoxification." Allergan's own labeling describes only general dermabrasion and cosmetic serum delivery. Both devices are sold with marketing language; we repeat none of it as fact.
How does each one work?
DiamondGlow. Allergan's "3X1" description has three things happening at once: a diamond tip exfoliates the skin, high-powered suction removes dirt and debris from the skin's surface and pores — Allergan calls this a deeper cleaning — and a SkinMedica Pro-Infusion Serum is delivered onto the skin.
The tips come in varying degrees of abrasion.
Allergan positions this as controlled physical exfoliation, explicitly contrasted with chemical exfoliation.
HydraFacial. The Syndeo user guide, dated November 7, 2024, states the device's intended use plainly: to abrade (exfoliate) the upper layers of the skin.
The seven-step count comes from the company's marketing of its Platinum tier — lymphatic support, cleansing and exfoliation, a peel, vortex extraction, booster serums, red or blue LED, and an antioxidant finish.
The lower tiers leave steps out: per the company's provider page, targeted booster serums and blue or red LED are only in the Deluxe and Platinum treatments, and the lymphatic step is Platinum-only.
Which HydraFacial tiers include which steps
| Step | Deluxe | Platinum |
|---|---|---|
| Booster serums | Yes | Yes |
| Blue or red LED | Yes | Yes |
| Lymphatic step | No | Yes |
Regulatory status, stated carefully: Hydrafacial's devices are listed with FDA as Class I powered dermabrasion devices, exempt from 510(k) premarket review.
For DiamondGlow, our search of FDA's 510(k) database found no clearance under the device's name, though we could not confirm which classification covers it — so we describe DiamondGlow as neither cleared nor approved.
No FDA approval or 510(k) clearance for either device turned up in our research, and Allergan says the SkinMedica serums are cosmetics that "have not been approved by the FDA."
Who performs it: the Syndeo guide says the system is for trained practitioners — and, for the medical version of the device, licensed ones — working within their licensing scope.
Who will run the device, and with what training, is a question to ask each spa before you book.
Which works better for your skin concern?
Honestly: no source we found answers that.
Our research turned up no head-to-head trial comparing the two devices, and neither maker's US label or intended-use statement names skin conditions to treat: DiamondGlow's labeled use is general dermabrasion plus cosmetic serum delivery, and the Syndeo guide's US intended use is exfoliating the upper layers of skin. (The acne indications our research found for HydraFacial are stated only for the European Economic Area, not the US.) What separates them is method, not measured results.
The published "results" our research turned up are maker-reported.
Hydrafacial's own pages report participant percentages for its treatment, citing company data and a company-cited 2018 study; Allergan's site shows a before-and-after photo rather than trial numbers, and our research found no clinical trial measuring DiamondGlow results.
Neither maker's figures tell you what your own skin would do.
Where the documents do speak plainly is the avoid-list.
Allergan's safety information contraindicates DiamondGlow on compromised skin: sunburned, chapped, irritated or broken skin, open wounds, active weeping acne, cold sores or herpetic ulcers.
The HydraFacial Syndeo guide lists active or inflammatory acne, eczema, rashes, psoriasis, sunburn, cold sores, open lesions or infection among the conditions its treatment is not for.
One contradiction worth knowing: Hydrafacial's consumer marketing has called its Clarifying treatment "clinically proven" for mild-to-moderate acne, while its US device guide puts active acne on the avoid-list — we follow the device guide and do not describe either device as an acne treatment.
Both makers' documents put compromised skin on the avoid-list, though the lists are not identical. Allergan's labeling contraindicates DiamondGlow on sunburned, chapped, irritated or broken skin, open wounds, active weeping acne, cold sores or herpetic ulcers; the HydraFacial guide says its treatment is not for skin with active conditions such as active or inflammatory acne, eczema, rashes, psoriasis, sunburn, cold sores, open lesions or infection. That makes the pre-treatment exam the real decision point: a licensed provider who looks at your skin can tell you whether either device is appropriate today, and what to address first.
Cost, number of sessions and downtime compared
How they are priced. Neither device has a confirmed national average price; what a spa charges is its own to set.
Hydrafacial publishes suggested retail prices — $250 for a Deluxe treatment and $325 for a Platinum treatment — but those are the maker's suggestions, not a survey of what med spas charge, and actual provider prices vary.
Allergan publishes no consumer price for DiamondGlow that we could find, and our research found no sourced US national average price for either device as of October 2026.
What you can compare are the quotes from the spas near you; the HydraFacial cost breakdown shows how much the tier a quote names changes what is in it.
Sessions. Allergan says a DiamondGlow treatment may be done every two weeks, or as your provider suggests, based on your skin concerns — that is the maker's guidance.
For HydraFacial we found no independent source saying how often to repeat it, and the tier you book changes what the session includes.
Spacing is a provider question either way.
Downtime and after-effects. Allergan calls DiamondGlow a noninvasive treatment with minimal downtime, so you can return to daily activities right after — the maker's characterization.
Its side-effect list: a scratchy, stinging sensation during the treatment, then temporary tightness, redness or slight swelling; rare serious effects include severe skin irritation and allergic reactions.
The HydraFacial guide describes temporary irritation, tightness or redness that usually fade within 72 hours.
Two practical instructions sit in DiamondGlow's own materials: prep — Allergan says to stop retinoids and other exfoliants at least three days before — and aftercare — sunscreen with SPF 30 or higher is advised afterward.
What each maker's documents say
| DiamondGlow | HydraFacial | |
|---|---|---|
| Published price | None found | $250 Deluxe, $325 Platinum (maker's suggested prices) |
| Session cadence | Every two weeks, or as your provider suggests | No independent source found |
| After-effects | Temporary tightness, redness or slight swelling | Temporary irritation, tightness or redness, usually fading within 72 hours |
Can you combine them, and in what order?
Neither maker's materials in our research give a rule for combining the two or for putting one before the other, and we will not invent a schedule.
What the documents do say draws a boundary around the question: each device leaves temporary after-effects (Allergan lists tightness, redness or slight swelling after DiamondGlow; the HydraFacial guide lists irritation, tightness or redness fading within 72 hours), and each maker's documents treat compromised skin as a reason not to treat (Allergan's labeling names irritated or broken skin outright; the HydraFacial guide lists active conditions such as rashes, open lesions or infection).
The closest thing to sequencing guidance on record is DiamondGlow prep: Allergan says to stop retinoids and other exfoliants at least three days before a treatment — a precaution framed around exfoliating products, though it names no device-to-device interval.
If a spa proposes both devices in one visit, ask what interval it uses between exfoliation treatments and why; the interval that suits your skin is a question for the provider who would do the treating.
Which should you book, and where near you?
Nothing we found crowns a winner, so the choice is not between a good and a bad device — it is between two overlapping treatments whose real, checkable differences are: the maker (Allergan Aesthetics versus Hydrafacial LLC), the method (DiamondGlow's single simultaneous step of physical exfoliation, suction and serum, versus a tiered sequence adding a peel and, on upper tiers, boosters and LED), the pricing paper trail (no published DiamondGlow price that we could find, maker-suggested prices for HydraFacial), and the cadence guidance (every two weeks for DiamondGlow, none on record for HydraFacial).
Vetting questions to settle before you book either one: which device the spa actually runs — they are different brand-name machines; which HydraFacial tier a quoted price covers; who performs the treatment and with what training; and whether the session price includes the serums.
Hydrafacial runs an official "Find a Hydrafacialist" locator and warns about resold or copycat devices; for DiamondGlow, ask directly whether the spa has the Allergan device.
On disclosure, Allergan's safety information asks patients to disclose pregnancy or breastfeeding, allergies and any topical medications, and the HydraFacial guide says its treatment is not for pregnant or lactating women — that use has not been evaluated.
Where near you: price-compare the spas in your area like for like — same device, same tier, same inclusions — and our guide to choosing a med spa walks the rest of the vetting.
Which of the two suits your skin is a question for a licensed provider who has examined it.
Frequently asked questions
Is DiamondGlow the same as HydraFacial?
No. DiamondGlow is Allergan Aesthetics' dermabrasion device: diamond-tip physical exfoliation, suction extraction and a SkinMedica serum, all at once.
HydraFacial is Hydrafacial LLC's device, whose maker markets a seven-step Platinum treatment with a peel, vortex extraction, booster serums and LED.
They share the exfoliate-and-infuse idea but are different machines with different maker guidance — and our research found no head-to-head trial that would rank them.
Is DiamondGlow or HydraFacial FDA-approved?
No FDA approval or 510(k) clearance for either device turned up in our research.
Hydrafacial's devices are listed with FDA as Class I powered dermabrasion devices, exempt from 510(k) premarket review; for DiamondGlow, we could not confirm which classification covers it.
Allergan says the SkinMedica serums used with DiamondGlow are cosmetics that have not been approved by the FDA.
For both devices, what the treatment is for comes from the maker's own documents.
Which is better for acne, DiamondGlow or HydraFacial?
In the US documents our research read — DiamondGlow's labeling and the HydraFacial Syndeo guide — neither maker presents its device as an acne treatment; the acne indications our research found for HydraFacial are stated only for the European Economic Area.
DiamondGlow is contraindicated on active, weeping acne, and the Syndeo guide lists active or inflammatory acne among the conditions its treatment is not for — even though Hydrafacial's consumer marketing has called its Clarifying treatment clinically proven for mild-to-moderate acne.
We follow the device guide.
For active acne or acne scarring, start with a licensed provider who treats acne before booking any device facial.
How often can you get a DiamondGlow or HydraFacial?
Allergan says DiamondGlow may be done every two weeks, or as your provider suggests based on your skin concerns.
For HydraFacial we found no independent source on how often to repeat it, so the interval is the provider's call.
Both makers' documents also put compromised skin on the avoid-list — DiamondGlow's labeling names irritated or broken skin, and the Syndeo guide lists active conditions such as sunburn, open lesions or infection — so back-to-back sessions of anything exfoliating are worth discussing with the provider first.
