Lovi Assistant explains

  • Excellent suitability for your dry skin is provided by humectants like Glycerin and Sodium Hyaluronate, which draw moisture into the skin, complemented by Panthenol and Allantoin to support barrier repair.
  • The high concentrations of 3-O-Ethyl Ascorbic Acid and Niacinamide offer significant brightening and evening of skin tone, addressing your concerns for dry or flaky skin.
  • The safety profile is excellent, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing agents like Aloe Barbadensis Leaf Extract.

How to apply

  • Apply this serum PM, starting 3×/week and working up to daily use as your skin adjusts.
  • Place the serum after cleansing and toner, but right before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
  • Apply the serum on slightly damp skin to help lock in extra moisture.
  • Avoid the eye area and do a patch test before your first use.
