Smart Health Tracker Ring Titanium IP68 Waterproof Sleep Heart Rate Monitor1
IP68 waterproofing likely uses water-repellent coating treatment; coating composition undisclosed.
Samsung does not disclose PFAS status for this wearable. The IP68 waterproof rating typically requires fluorinated or non-fluorinated water-repellent coatings, but the brand provides no transparency on which is used here.

The full breakdown
What it's made of and why it matters
The Galaxy Ring uses a titanium body, which is a biocompatible, corrosion-resistant metal that does not leach heavy metals or degrade under normal wear. The critical unknown is the waterproof coating formulation applied to achieve IP68 rating. Samsung has not publicly disclosed whether this uses PFAS-based water-repellent coating (water-repellent coating) treatments, Teflon-family coating sealants, or non-fluorinated alternatives. Titanium itself poses no established chemical leaching risk, but any coating applied to it is the potential weak point.
The brand's record and disclosure
Samsung has not released specific material safety data sheets or coating compositions for the Galaxy Ring. The company maintains general sustainability commitments but has been largely silent on PFAS use in wearable devices specifically. Samsung has faced scrutiny in past product lines (particularly textiles and electronics) for limited pre-market chemical transparency, though no recalls specific to this ring are on record. The lack of proactive disclosure about waterproof coatings is a transparency gap, not proof of hazard.
How it compares in its category
Smart rings are an emerging category with limited public chemical safety benchmarking. Most competitors (Oura, RingConn) similarly withhold detailed coating information. The titanium material choice is premium and safer than aluminum or steel alternatives that may corrode or require more aggressive protective coatings. However, the entire category relies on undisclosed surface treatments to achieve water resistance, making direct safety comparison difficult. Wearables worn 24/7 against skin warrant higher disclosure standards than one-use products.
If you buy it
Wear the ring continuously as designed; titanium is durable and hypoallergenic for prolonged skin contact. Rinse with plain water after swimming or sweating to minimize salt/sweat contact with the coating. Avoid prolonged exposure to harsh chemicals, chlorine pools, or abrasive cleaners that could degrade the waterproof layer. If the coating visibly chips, flakes, or the water resistance fails, contact Samsung for repair or replacement rather than attempting DIY waterproofing. Expect to replace the device every 2-3 years as battery degradation becomes the limiting factor, not material breakdown.
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.”
Waterproof coating composition (likely fluorinated)
IP68 waterproofing in wearables typically requires water-repellent coating or Teflon-family coating treatments. Samsung has not disclosed whether its coating contains PFAS chemicals. Skin contact with fluorinated coatings during daily wear is low-risk if intact, but degradation or manufacturing defects could increase exposure. No independent testing of this specific product's coating is publicly available.
Coating degradation and micro-flaking
Wearable coatings degrade with repeated flexing, sweat exposure, and mechanical friction over 1-2 years. If the waterproof layer flakes and is ingested or inhaled in particles, it poses an unknown hazard. This is a durability and maintenance issue more than an acute chemical risk, but uncontrolled degradation is a factor in long-term wearability.
Skin sensitization or irritation from coating
No reported cases of allergic reactions or dermatitis specifically linked to Galaxy Ring wearers. Titanium itself is hypoallergenic. However, without disclosed coating identity, individual sensitivity cannot be fully ruled out; persons with sensitive skin should monitor for rashes during initial wear.
Nickel presence in alloy
Samsung markets the Galaxy Ring as titanium, implying high-purity grade. Medical-grade titanium typically contains minimal nickel (under 0.3%). No documented nickel hypersensitivity cases for this product exist, but the alloy composition is not independently verified in public data.
Battery chemical leakage (enclosed system)
The ring's internal battery is sealed and unlikely to pose leakage risk during normal use or even after water immersion, given IP68 rating. Risk is minimal unless the device is deliberately disassembled or damaged. Proper disposal via electronics recycling is recommended at end of life.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
