Brilante Max Serum may be used for conditions such as melasma, pimple marks, and uneven skin tone. It contains ingredients such as niacinamide, alpha-arbutin, and potassium azeloyl diglycinate, which can help reduce pigmentation, improve skin brightness, and support a more even complexion over time. It may also help with post-acne marks and overall skin texture. Since you have facial pigmentation issues, regular and consistent use is important for better results. You can apply the serum twice daily as part of your skincare routine. First, cleanse your face with water or a mild cleanser and pat it dry gently. Then press the pump twice onto your fingertips. Apply the serum to your face and neck, then gently massage in circular motions until it is fully absorbed. Follow it with a suitable moisturiser and sunscreen during the daytime for added protection. If you experience irritation or worsening sensitivity, stop using the serum and consult a dermatologist.
