NACOMI Next Level Serum with Mandelic Acid + PHA 10%, 30 ml Serum with Mandelic Acid + PHA is an innovative serum that combines the action of mandelic acid and PHA (polyhydroxy acids). The two ingredients work synergistically to offer intense exfoliation, smoothing and hydration to the skin. The serum is ideal for skin with signs of ageing, discolouration and uneven texture. Thanks to its formula, the product provides comprehensive skin care, improving the skin's condition and appearance. Mandelic acid is an alpha hydroxy acid (AHA) that gently exfoliates the epidermis to remove dead skin cells, leading to a smoother surface and improved skin tone. It also has a brightening effect, reducing hyperpigmentation and sun spots. PHAs (polyhydroxy acids), such as gluconolactone, are gentler than AHAs but work effectively on the skin's surface, offering additional hydration and protection. PHAs aid exfoliation while being less irritating, making them suitable for sensitive skin.Skin benefits:Gentle exfoliation: Removing dead skin cells, leading to a smoother surface.Reducing hyperpigmentation: Brightening spots and uneven skin tone. Improving skin texture: Smoothing and unifying the surface. Hydration: The action of PHAs promotes hydration, improving skin comfort. Skin enhancement: Reducing the appearance of fine lines and wrinkles. How to use: Apply a small amount of serum to cleansed face, neck and décolleté, avoiding the eye area. Gently massage in with fingertips until completely absorbed. The serum can be applied in the evening, 2-3 times a week, depending on skin tolerance. After applying the serum, it is recommended to apply a moisturiser and use sunscreen during the day to protect the skin from UV rays and promote the regeneration process. For first-time use or sensitive skin, it is worth conducting a tolerance test before full application.
