NFC Smart Ring Men Women Heart Rate Health Monitor Sleep Monitors Smartring IP68 Waterproof
Smartring with undisclosed waterproof treatment, PFAS risk unclear.
Samsung's smart ring uses IP68 waterproofing but does not disclose coating materials or PFAS status. Unspecified waterproof treatments on wearables commonly contain PFAS alternatives; no lab data available.

The full breakdown
What it's made of and why it matters
The ring body is titanium alloy, a biocompatible metal that does not leach under normal skin contact. However, the IP68 waterproof rating depends on coatings or sealants applied to the device; Samsung has not publicly disclosed the chemical composition of these treatments. Waterproof coatings on wearables often contain fluorinated polymers or silicone-based water barriers, some of which may contain PFAS or other volatile compounds. The unspecified nature of this coating is the primary safety unknown for this product.
The brand's record and disclosure
Samsung has not published specific material safety data sheets or coating compositions for this smartring model. The company has faced scrutiny on PFAS use in electronics manufacturing but has not issued public commitments specific to wearable coatings. No independent safety certifications (e.g., Oeko-Tex, GOTS) are advertised for this wearable, which is typical but leaves verification gaps. Contacting Samsung support for coating details before purchase is recommended if PFAS avoidance is a priority.
How it compares in its category
Most smartrings (Oura, Whoop) also use undisclosed waterproof treatments and face similar PFAS uncertainty. Titanium alloy as a substrate is more durable and hypoallergenic than stainless steel alternatives. Samsung's entry is competitively priced but offers no material transparency advantage over competitors. No wearable ring manufacturer has achieved widespread third-party verification of PFAS-free coatings to date.
If you buy it
Store the ring in a cool, dry place and avoid prolonged exposure to extreme heat (above 50C), which could accelerate coating degradation. Clean the ring weekly with a soft, damp cloth; avoid harsh solvents or abrasive scrubbing that may compromise the waterproof layer. Monitor the device for visible wear, peeling, or discoloration of the coating over 12-18 months; replacement may signal coating failure. Request Samsung support documentation on the waterproof coating chemistry if you have sensitivities or PFAS concerns.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Undisclosed waterproof coatings (potential PFAS or other fluorinated compounds)
IP68 rating requires surface treatment; Samsung has not disclosed composition. Fluorinated polymers are standard in waterproof electronics but may include legacy or non-legacy PFAS depending on formulation. Skin contact with a worn ring minimizes but does not eliminate exposure risk if coating degrades.
Coating degradation and leaching over time
Wearable electronics experience mechanical stress and sweat exposure that can compromise sealant integrity. No published durability data from Samsung exists for this model; anecdotal reports of similar smartrings show visible wear within 12-24 months of daily use. Degraded coatings may release unidentified breakdown products.
Nickel or other heavy metal traces in titanium alloy substrate
Medical-grade titanium alloys typically contain less than 0.1% nickel and are hypoallergenic; Samsung has not published alloy specifications for this ring. Risk to skin is minimal for most users, but those with severe nickel sensitivity should verify alloy composition with Samsung before purchase.
Electronic component toxins (solder, adhesives, internal circuit materials)
Internal electronics are sealed and pose no direct exposure via skin contact during normal wear. Improper disposal (throwing in trash rather than e-waste recycling) could release heavy metals from solder or batteries into the environment; responsible recycling mitigates this risk.
Skin irritation from sweat accumulation under the ring
Titanium alloy itself is biocompatible, but moisture trapped under continuous wear can promote bacterial or fungal growth on skin. This is a hygiene issue rather than a material toxicity issue; daily removal and drying of the ring and skin beneath it prevents problems.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
