Lovi Assistant explains

  • This serum offers moderate benefits for your dry and sensitive skin, with Glycerin and Sodium Hyaluronate providing essential hydration to combat dryness and flakiness. The inclusion of Hydrolyzed Wheat Protein and Hydrolyzed Soy Protein also aids in repairing your skin barrier.
  • While the peptides like Acetyl Octapeptide-3 and Acetyl Hexapeptide-8 are beneficial for reducing the appearance of fine lines and wrinkles, their concentration may not fully address your primary concern of dryness.
  • The product is safe for your skin, as it contains no harsh or irritating ingredients and is suitable for sensitive complexions.

How to apply

  • Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
  • Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
  • Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
  • Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
  • Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.
