Samsung · Water-Resistant Smart Rings & Bands
Samsung Galaxy Ring, Ai Smart Ring, Size 7, Titanium Gold
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes titanium alloy, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Nickel leaching (from titanium alloy impurities)
Medical-grade titanium is typically nickel-free or contains <0.05%, but commercial titanium alloys can include up to 0.8% nickel. Nickel contact dermatitis is rare with Grade 5 (implant-grade) titanium but possible with lower-purity alloys if Samsung uses cost-reduced sources. No recall or adverse reports exist for Galaxy Ring, but sensitive individuals should monitor for localized rash.
Battery electrolyte leakage
The Galaxy Ring contains a rechargeable battery sealed inside. If the seal is compromised by drop impact or wear, internal electrolyte (typically lithium-ion fluid) could contact skin. This would cause chemical burns or irritation. Risk is low with proper sealing, but users should stop wearing the device if it cracks visibly.
Skin maceration or bacterial colonization under ring
Any worn ring can trap sweat, dead skin, and bacteria, leading to folliculitis or fungal infection if worn continuously without cleaning. This is a hygiene risk, not a chemical hazard, but more likely with porous materials. Titanium's smooth, non-porous surface limits bacterial growth compared to silicone or rubber bands.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Sensor material toxicity (rare earth, adhesives)
The device contains optical and thermal sensors, likely using biocompatible epoxy adhesives and encapsulated electronics. No complaints of allergic reaction or heavy-metal leaching from Galaxy Ring sensors have been documented. The sealed design prevents direct skin contact with internal components.
Formaldehyde / VOCs
Medical-grade wearable adhesives are typically formaldehyde-free. Samsung's sealed construction and lack of reported off-gassing complaints suggest acceptable adhesive choices, but full material disclosure is not public. Minimal risk compared to fabric or polymer-heavy wearables.

What it's made of and why it matters
The Galaxy Ring uses a titanium alloy body, a biocompatible material commonly used in medical implants and high-end jewelry. Titanium does not leach significant ions or chemicals into skin under normal wear, and it is resistant to corrosion and oxidation. Unlike lower-cost alloys (nickel, lead-containing solder), titanium poses minimal dermal or systemic toxicity risk. The interior likely contains a battery and sensors, but these are sealed and not in contact with skin.
The brand's record and disclosure
Samsung has not issued a public PFAS statement for the Galaxy Ring or made commitments specific to fluorochemical avoidance in wearables. The company has faced scrutiny over water-resistant coatings in smartphones and appliances, though no documented PFAS use has been confirmed in Galaxy Ring materials. Samsung's broader sustainability reporting does not detail wearable material certifications. For a device marketed as water-resistant, the absence of a declared water-repellent coating is notable and lowers the likelihood of PFAS use.
How it compares in its category
Smart rings as a category pose fewer chemical hazards than textiles or coated cookware because contact is limited to skin and duration is intermittent. Titanium alloy competitors (Oura Ring Gen 3, Ultrahuman Ring Air) use similar materials with comparable safety profiles. The Galaxy Ring's sealed electronics and lack of a stated Teflon-family coating or wax finish make it lower-risk than rubber or silicone-band wearables, which can off-gas volatile compounds or harbor bacteria if porous.
If you buy it
Rinse the device with fresh water after salt-water or chlorine exposure to prevent corrosion and mineral buildup on sensors. Do not expose it to extreme heat (>60°C / 140°F) for extended periods, as the battery and adhesives may degrade. If the titanium surface develops pitting or the seal fails, discontinue use and request a replacement. Clean it weekly with a soft, dry cloth and avoid abrasive cleaners; this extends sensor accuracy and prevents skin irritation from trapped sweat.
