Samsung Galaxy Ring No Smart Ring activity tracker IP68 Gold
IP68 waterproofing raises PFAS concern; Samsung discloses no coating details.
Samsung Galaxy Ring achieves IP68 waterproofing through unspecified coating treatments, likely water-repellent coating-based. No public PFAS disclosures or testing available from brand or third parties.

The full breakdown
What it's made of and why it matters
The Galaxy Ring uses titanium for the band (biocompatible, corrosion-resistant, hypoallergenic) and ceramic for the sensor back (inert, non-leaching). Stainless steel components add durability. The critical unknown is the waterproof coating applied to achieve IP68 rating; Samsung does not publicly specify whether this uses fluorinated polymers (PFAS-based), silicone, or other hydrophobic chemistry. This coating sits against skin during continuous wear, making its composition a legitimate concern for chronic exposure.
The brand's record and disclosure
Samsung has not published material safety data sheets, coating composition details, or PFAS commitment statements for the Galaxy Ring. The company's broader sustainability messaging emphasizes recycling and energy efficiency but does not address chemical use in wearables. No independent safety recalls or regulatory warnings have been issued for this product. Samsung's silence on coating chemistry is consistent with limited disclosure across the wearables industry, but contrasts with cosmetics and personal care brands that increasingly detail restricted substances.
How it compares in its category
Most smart rings (Oura, Whoop, RingConn) use similar titanium or alloy bodies with unspecified waterproof coatings; transparency across the category is poor. Mechanical watches and fitness bands face identical coating opacity issues. The Galaxy Ring's ceramic sensor back is more skin-friendly than some competitors' materials, but provides no advantage regarding coating risk. Wearables as a category lag behind cookware and food storage in material disclosure standards.
If you buy it
Wear the ring continuously as designed; titanium and ceramic are stable during normal use and unlikely to leach. Avoid intentional abrasion or scratching of the band, which could breach the waterproof coating and accelerate unknown risks. Clean with mild soap and water after sweating or saltwater exposure to minimize skin irritation from coating byproducts. Replace the device if coating visibly degrades (cracking, discoloration, or peeling); Samsung offers trade-in and repair through its service network.
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.”
Unspecified waterproof coating composition
IP68 rating requires a hydrophobic layer; Samsung does not disclose whether this uses fluorinated compounds, silicone, polyurethane, or other chemistry. Continuous skin contact heightens exposure uncertainty, particularly for sensitive individuals.
Titanium and stainless steel biocompatibility
Both materials are widely used in implantable medical devices and are well-tolerated. Nickel content in stainless steel can trigger contact dermatitis in sensitive individuals, but no product-specific allergic reaction reports are on record.
Ceramic sensor back degradation
Ceramic is chemically inert and does not leach heavy metals under normal use. Mechanical damage (dropping, impact) could create sharp edges or glazing exposure, but this is a physical hazard rather than chemical.
Skin irritation from sweat or friction
Continuous wearables can trap sweat and bacteria under the band, especially if the coating traps moisture. This is a mechanical/microbiological concern rather than chemical toxicity, but exacerbated if coating composition prevents skin breathability.
Heavy metals in electronic components
Wearable electronics commonly contain solder, rare earths, and battery materials; Samsung meets EU RoHS standards for most components. No product-specific heavy metal contamination or leaching has been reported.
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.
