Proper technique with a buffer reduces the risk of damaging the natural nail during the smoothing process. Regular use of a buffer can improve nail health by promoting circulation and removing dead skin cells.

• Callus softeners

  • Topical products designed to break down hardened skin on feet and hands, promoting smoothness and comfort. They often contain exfoliating agents like alpha-hydroxy acids or urea for effective results. Common ingredients include salicylic acid, urea, and lactic acid that help dissolve dead skin. Used mainly in pedicures and manicure treatments for softening callused areas. Application usually requires a short dwell time, followed by gentle scrubbing. Always perform a patch test to check for skin sensitivity before full application.

• Catalyst

  • In beauty treatments enhances the effectiveness of products by accelerating reactions, improving outcomes like coloring or chemical processes in hair and skin treatments.

• Collagen

  • A natural protein that provides structure and elasticity to the skin, important for maintaining a youthful appearance and firmness. Collagen production naturally declines with age, leading to sagging skin and wrinkles. Certain lifestyle factors like smoking and excessive sun exposure can accelerate collagen degradation. Consuming collagen-rich foods like bone broth or taking collagen supplements may help boost skin health. Collagen creams and treatments claim to enhance skin elasticity, but their effectiveness varies among individuals.

• Comedo

  • A clogged hair follicle in the skin resulting from excess oil production, leading to blackheads or whiteheads. Blackheads occur when the comedo is open at the surface of the skin and the trapped oil is exposed to air. Whiteheads develop when the comedo is closed at the surface and the trapped oil remains beneath the skin's surface. Regular exfoliation can help prevent comedones by removing dead skin cells that can block pores. Comedones are common in individuals with oily skin and can be treated with topical retinoids or salicylic acid.

• Comedogenic

  • Refers to substances that have the potential to cause clogged pores and promote the formation of comedones or acne. Ingredients like mineral oil, coconut oil, and cocoa butter are often considered highly comedogenic. Non-comedogenic products are formulated to minimize the likelihood of clogging pores.
