Colgate Optic White Platinum Whitening Toothpaste — Family 4-Pack, Hydrogen Peroxide Formula, Removes 10 Years of Stains (4 × 4.1 oz)

Colgate Optic White Platinum is the brand's premium whitening tier — uses 1% Hydrogen Peroxide as the active whitening agent, the same compound dentists use in professional whitening treatments at lower concentrations than the in-office formulas. Hydrogen Peroxide whitens through oxidation (chemical lightening of stain molecules) rather than the abrasive surface-lifting used by Crest 3D White. This matters for Korean shoppers because peroxide-based whitening works on intrinsic stains (inside the tooth) as well as surface stains.

4 tubes × 4.1 oz (mid-size). At normal use (pea-sized, 2× daily), each tube lasts ~7 weeks; the pack provides ~28 weeks (about 6.5 months). Most aggressive whitening in the Colgate retail lineup — not recommended for daily long-term use due to peroxide; ideal for 4-6 week intensive whitening cycles followed by switching to a gentler maintenance paste.

1. Apply a pea-sized amount to a soft-bristled toothbrush.
2. Brush teeth thoroughly for at least 2 minutes; cover all surfaces.
3. Use 2× daily — morning and evening.
4. Spit out excess. Do not rinse immediately for max peroxide contact.
5. Visible whitening typically begins around day 5-7; continue 4-6 weeks for full effect.
6. Do NOT use in children under 12. Adult use only.

Korean shoppers comparing Colgate Optic White Platinum to Crest 3D White Brilliance face a meaningful decision — both are top-tier whitening pastes, but they work differently. Colgate's 1% Hydrogen Peroxide acts chemically (bleaches stain molecules); Crest's foam acts physically (lifts surface stains). For intrinsic discoloration (yellowing from age, antibiotics in childhood, mineral exposure), Hydrogen Peroxide is more effective.

The "10 years of stains" marketing claim is FDA-monitored — Colgate's clinical data supports it for users with significant coffee, tea, or wine staining built up over time. Korean shoppers with longstanding stain issues (heavy coffee drinkers, smokers) specifically choose Platinum over the standard Optic White line.
