Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate hydration for your dry and flaky skin, as glycerin and hyaluronic acid draw moisture into the skin to improve its texture and suppleness.
  • The peptides in the formula, such as Acetyl Hexapeptide-8 and Palmitoyl Tripeptide-1, provide excellent plumping and firming benefits, enhancing overall skin appearance.
  • The product is safe for your dry and sensitive skin, with no risks of irritation due to the absence of harsh or prohibited ingredients.

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.
