Lovi Assistant explains

  • Offers moderate exfoliation for your dry and sensitive skin due to the presence of lactic acid, citric acid, and salicylic acid, which can strip natural oils and exacerbate dryness.
  • While these acids are effective for smoothing texture and reducing blemishes, they are not ideal for providing the emollient and humectant actions your dry skin needs.

How to apply

  • Use this exfoliating toner only in your PM routine, starting 1×/week since your skin is sensitive. Carefully build up frequency only if your skin feels comfortable.
  • Apply the exfoliating toner after using your cleanser and before your final moisturizer. This ensures it works effectively on clean skin.
  • Gently press 2-3 drops of the exfoliating toner into your skin using your hands. Avoid rubbing to prevent any irritation.
  • Apply the exfoliating toner on completely dry skin to ensure better tolerance for your sensitive type. Let it absorb fully before moving to the next step.
  • Do a patch test before your first use and avoid the delicate eye area. Keep this product separate from other strong acids or retinoids to protect your skin barrier.

People Say

★4.7Overall rating based on 800+ reviews

This acid toner is highly praised for dramatically resurfacing skin texture, clearing acne, and creating a radiant glow. While the strong vinegar-like scent and initial stinging are frequently mentioned drawbacks, the majority of users find the transformative effects on pores and hyperpigmentation justify the discomfort and cost.

What does Salicylic Acid do for dry sensitive skin?

Salicylic acid is generally a poor fit for dry, sensitive skin because it is designed to clear out pores by removing excess oil, which can easily leave dry skin irritated.
