Lovi Assistant explains

  • Offers moderate treatment for acne lesions due to the presence of sulfur, which can be drying and irritating for your dry and sensitive skin. Polyethylene glycol also contributes to dryness, making it less suitable for your skin type.
  • While sulfur offers moderate exfoliation, its drying nature may worsen your dry or flaky skin concerns.

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.

Questions and answers

Why does Lovi advise caution with De La Cruz 10% Sulfur Ointment for dry sensitive skin?
