Lovi Assistant explains

How to apply

  • Use this soothing AM and PM routine every day to keep your normal skin calm. Always remember to apply SPF in the morning after your moisturizer.
  • Apply your moisturizer after your toner in the morning, and after your serum in the evening. This step locks in hydration and protects your skin.
  • Gently press a small amount of the moisturizer evenly across your face. Avoid rubbing to keep your sensitive skin happy and calm.
  • You can apply this gentle formula on dry or slightly damp skin for the best comfort. It works wonderfully on clean skin to soothe redness and irritation.
  • Do a patch test before your very first use to check your skin's reaction. Avoid getting the product directly into your eyes .
