Analysis of the Unique Formula

Powerful Whitening Duo: The combination of carbamide peroxide and hydrogen peroxide, two powerful whitening agents, work in synergy to quickly break down stubborn surface stains, enabling you to reveal your most brilliant smile in no time.

Refreshing Add - on Ingredients: The addition of peppermint and xylitol not only provides a fresh taste but also enhances the oral environment.

The Science Behind Whitening

This serum is rich in hydrogen peroxide and carbamide peroxide, which are the gold - standard whitening agents commonly used in dental clinics. During the whitening process, they actively penetrate the surface of the tooth enamel and break down stain molecules. Through this rapid oxidation process, after continuous use for a few minutes, surface stains and tooth discoloration can be removed, presenting a brighter smile.

Key Ingredient Analysis

Hydrogen Peroxide: A compound with strong oxidizing power, commonly used in bleaching and disinfection. In dentistry, it can break down the organic molecules that cause tooth staining, achieving a whitening effect.

Sodium Hydroxide: Also known as caustic soda, it is often used to adjust the pH value of products and plays a corresponding role in teeth - whitening products.

PEG - 400: A water - soluble and biodegradable liquid that helps active ingredients better penetrate and adhere to the surface of tooth enamel, enhancing the whitening effect and acting as a lubricant to reduce discomfort during the whitening process.
