Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers excellent exfoliation for your normal skin due to gluconolactone and citric acid, which smooth texture and provide mild chemical exfoliation for redness and irritation.
- Niacinamide and ceramides further support your skin barrier and offer mild keratolytic action, enhancing overall skin health.
- The formulation is safe for your sensitive skin, as it lacks harsh ingredients and minimizes irritation risks.
How to apply
- Use your exfoliant PM once a week to help with redness and irritation. Start slowly and only increase frequency if your skin feels happy and comfortable.
- Apply the exfoliant after cleansing and toner , but always before your moisturizer . This ensures the product absorbs properly into the skin.
- Gently press 2-3 drops of the exfoliant into your skin without rubbing . Let it absorb for a minute before moving on.
- Since your skin is sensitive , apply the exfoliant on completely dry skin for the best tolerance. This helps prevent any extra stinging or discomfort.
- Always do a patch test before your first use and avoid the delicate eye area .
