Lovi Assistant explains

  • Offers moderate brightening and evening of skin tone for your dry and sensitive skin, as diglucosyl gallic acid and niacinamide work to treat dark spots while glycerin and shea butter provide essential hydration and emollient effects.
  • Grape seed oil and argan oil offer additional moisturizing benefits, supporting your dry or flaky skin concerns.
  • The product is safe for your dry and sensitive skin, containing no harsh ingredients and including soothing components like shea butter and argan oil.

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.
