Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your dry and sensitive skin due to gluconolactone and lactic acid, which provide some skincare benefits but pose major risks of worsening dryness.
- The formulation is unsuitable for your dry skin as these acids have a keratolytic action that can be too harsh.
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 200+ reviewsUsers consistently describe this toner as a "facial in a bottle" specifically suited for mature, dry, or "devitalized" skin due to its vitamin-enriched formula. While gentler than the original P50, it is highly praised for effectively resurfacing texture and creating a "glass skin" glow without stripping moisture, though the application process requires tolerance for its potent scent and sensation.
