Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate exfoliation for your oily skin and acne, blemishes, and breakouts due to the presence of salicylic acid, which helps to unclog pores and reduce inflammation.
  • The formulation is highly suitable for oily skin, with salicylic acid providing keratolytic action and seboregulation.
  • The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of prohibited or harsh ingredients.

How to apply

  • Use this exfoliant as part of your PM routine once a week to start, increasing frequency only if your skin tolerates it well.
  • Apply the exfoliant after cleansing and toning, but before your final moisturizer step.
  • Gently press 2-3 drops of the exfoliant into your skin and let it absorb for a minute.
  • Apply the product directly onto clean, dry skin for the best results against breakouts.
  • Avoid the sensitive eye area and always use a daily SPF since exfoliating makes skin more sensitive to the sun.
