Waterproof coating raises concern; Samsung discloses nothing about PFAS.
Samsung Galaxy Ring uses unspecified waterproof treatment on metal and crystal surfaces. Brand provides no PFAS transparency or testing data; material composition vague.

The full breakdown
What it's made of and why it matters
The Galaxy Ring uses a titanium or stainless steel band with a sapphire crystal cover. Titanium and sapphire are chemically stable and do not leach heavy metals or degrade under normal skin contact. The unknown waterproof coating is the weak point: manufacturers typically use Teflon-family coating-based sealants (often Teflon-type coating or Teflon-type coating variants) to waterproof wearable electronics, and these may contain or release PFAS compounds over the product's lifetime, especially if the coating degrades from sweat, UV exposure, or wear.
The brand's record and disclosure
Samsung has not publicly disclosed the specific chemical composition of the Galaxy Ring's waterproof coating or confirmed whether it is PFAS-free. The company does not appear to have made a corporate PFAS phase-out commitment as of the most recent public statements. Samsung's broader electronics division has faced scrutiny over supply-chain chemical management, but no specific recalls or safety alerts have been issued for the Galaxy Ring. Without transparent coating data, consumers cannot verify the absence of PFAS.
How it compares in its category
Smart rings are a nascent product category with limited independent safety testing and no established industry standard for waterproof coating disclosure. Competitors such as Oura and Amazon Halo also use proprietary waterproof coatings without public PFAS declarations, making this a category-wide transparency gap rather than a Samsung-specific failing. Wearables with metal bands generally pose lower hazard risk than plastic or rubber-heavy designs, but all waterproof electronics carry latent PFAS concern if coatings are not disclosed as PFAS-free.
If you buy it
Clean the ring weekly with non-abrasive cloth and avoid prolonged exposure to harsh soaps or high heat (saunas over 80C may stress the coating). Inspect the band monthly for cracks, peeling, or discoloration of the coating; if visible degradation appears, stop wearing it and contact Samsung support to assess replacement options. Do not use a ring cleaner with acetone or other solvents, which may accelerate coating breakdown. If you have concerns about PFAS exposure or skin sensitivity, request Samsung's safety data sheet for the waterproof coating before purchase; if they decline, that refusal itself is a risk signal.
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.”
PFAS in waterproof coating
Waterproof coatings for wearables commonly contain Teflon-family coating; Samsung has not disclosed whether the Galaxy Ring coating is PFAS-free. Degradation of the coating over time could increase dermal exposure to residual PFAS or fluorine compounds.
Coating degradation and unknown leachables
The composition of the proprietary waterproof coating is not public. Without disclosure, it is impossible to rule out leaching of other chemical additives (plasticizers, adhesive compounds, cross-linking agents) if the coating wears or peels from prolonged sweat and friction.
Heavy metals in coating or metal band
Titanium and surgical stainless steel are hypoallergenic and do not leach nickel or cadmium under normal skin contact. No safety alerts have been issued for the Galaxy Ring band material itself.
Contact dermatitis or skin irritation
Wearables in constant contact with skin may trigger irritation if coating degrades, sweat accumulates under the band, or if metal impurities or residual manufacturing solvents persist. Samsung does not provide allergen or irritant data for the coating.
Functional failure due to moisture ingress
If the waterproof coating fails prematurely, water ingress could damage electronics and potentially expose the wearer to battery leakage or short-circuit hazards, though Samsung rates the ring IP68 (suitable for swimming).
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.
