Lovi Assistant explains
- Offers moderate exfoliation for your normal skin due to glycolic acid, which smooths texture and supports barrier repair with niacinamide.
- Panthenol and sodium hyaluronate provide hydration and soothing benefits, which are supportive for your wrinkles and fine lines.
- The product is safe for your normal skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Use this exfoliant product in your PM routine once a week to start, increasing frequency only if your skin tolerates it well. Always apply SPF the next morning to protect your skin.
- Apply this exfoliant product after cleansing and toner, but before your moisturizer. This ensures the best absorption into your skin.
- Gently press 2-3 drops of the exfoliant product into your face, avoiding any rubbing. Let it absorb for a minute before moving to the next step.
- Apply this exfoliant product on completely dry skin to get the best results. This helps your normal skin accept the product smoothly.
- Avoid the sensitive eye area while using this exfoliant product. Do a patch test before your first use and avoid mixing it with strong acids.
