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.
Heavy metals
Silicone can be formulated with various dyes and surface treatments. Without published material specs, trace metals in pigments or undisclosed coatings cannot be ruled out. Direct skin contact over hours daily suggests low acute risk, but long-term dermal accumulation is not quantified for this specific product.
Source, FDA ↗Stainless steel caseback nickel content
Stainless steel alloys can contain nickel (1-8% typical). Individuals with nickel sensitivity may experience dermatitis with prolonged back-of-wrist contact; Xiaomi does not publish nickel content or hypoallergenic certifications for this model.
PFAS
The band is marketed as water-resistant; such durability typically relies on Teflon-family coating coatings (PFAS-containing) or silicone hydrophobic treatments. Xiaomi has not disclosed which method is used, leaving PFAS presence ambiguous despite the earlier 40/100 PFAS grade reflecting this uncertainty.

Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Aluminum frame corrosion and leaching
Aluminum is typically anodized or coated to prevent leaching; stainless steel caseback isolates the aluminum from direct prolonged skin contact. No reports of aluminum leaching from Xiaomi wearables at normal wear temperatures exist in public records.
AMOLED display UV or blue-light exposure
AMOLED displays emit blue light similar to standard LED screens. Daily wrist-worn exposure at viewing distances poses negligible additional risk compared to smartphones and is not a known safety concern for this device category.
The full breakdown
What it's made of and why it matters
The Xiaomi Smart Band 10 Pro uses silicone for the wrist band, an aluminum frame, stainless steel caseback, and an AMOLED display. Silicone is generally regarded as inert and non-toxic during normal skin contact, though the specific formulation, colorants, and any coatings applied are not publicly detailed by Xiaomi. The aluminum frame and stainless steel components are stable under normal wear conditions and unlikely to leach in skin-contact scenarios. The AMOLED display uses standard display chemistry with no known consumer safety concerns from brief daily viewing.
The brand's record and disclosure
Xiaomi has not published detailed material safety data sheets or certifications (e.g., FDA medical device status, CE compliance specifics for wearables) for this model. The brand maintains a general posture of silence on PFAS use in consumer products, consistent with many electronics manufacturers that do not voluntarily disclose water-resistant surface treatments. No major product recalls or safety controversies specific to this band model have entered the public record. Without certification documents or third-party testing, material provenance cannot be independently verified.
How it compares in its category
Most fitness trackers in this price segment (under $100 USD) rely on silicone bands and use similar aluminum or stainless steel frames; transparency levels are similarly low across the category. Xiaomi's build quality is consistent with mid-tier competitors and does not deviate significantly in material selection. Premium wearables (e.g., Apple Watch) also employ silicone and aluminum but publish more detailed material certifications. Budget alternatives often lack water resistance, so Xiaomi's water-resistant design is a category norm rather than a differentiator.
If you buy it
Rinse the band regularly with clean water after sweating or water exposure to remove salt and debris that may degrade silicone over time. Avoid prolonged exposure to direct sunlight and store in a cool, dry place when not in use. If the silicone band shows visible cracking, stiffening, or discoloration after 1-2 years, replacement is advisable; third-party silicone bands are widely available and may offer material alternatives. Do not heat the device or expose it to solvents, as these could accelerate coating or material breakdown.
