Lipstick and Nail Polish Tests

At MassLab, we offer comprehensive testing services for lipstick and nail polish products to ensure that they meet the highest quality, safety, and efficacy standards. As makeup products that come into direct contact with the skin, lips, and nails, it is essential that these products are safe, free from allergens or toxic substances, and perform as promised.

Importance of Lipstick and Nail Polish Testing

Lipsticks and nail polishes are designed to enhance aesthetic appearance while also protecting skin health. Since lipsticks are applied directly on the lips and nail polishes affect nail health, they must:

• Be free from harmful chemicals (e.g., heavy metals, formaldehyde, parabens, phthalates)
• Maintain long-lasting color and coating integrity
• Provide effective performance without causing irritation or allergic reactions

Thorough testing ensures that these products meet stringent cosmetic safety standards, thereby protecting consumers and enhancing market trust.

• Objective:
  To analyze the chemical composition of lipsticks and nail polishes for the presence of potentially harmful substances such as heavy metals (lead, cadmium, nickel), formaldehyde, parabens, and phthalates.
