Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate exfoliation for your oily skin, as salicylic acid helps manage excess sebum and decongest the pores. This ingredient is well-suited for your skin type and main goal of reducing oily shine.
  • The formula provides general skincare benefits by mildly exfoliating the skin's surface.
  • The product is safe for your oily skin, with no risks of irritation due to the absence of harsh ingredients.

How to apply

  • Use this exfoliant product as part of your PM routine once a week. Start slowly and build up frequency only if your skin tolerates it well.
  • Apply the exfoliant after cleansing and toner, but right before your moisturizer.
  • Gently press 2-3 drops of the exfoliant into your skin and let it absorb fully. Avoid any harsh rubbing to keep your skin calm.
  • Apply the exfoliant directly onto completely dry skin to get the best balance and results. Clean, dry skin helps the product work evenly.
  • Always avoid the delicate eye area when applying. Be sure to use a broad-spectrum SPF 30+ daily while using exfoliating acids.
