Lovi Assistant explains
- Highly suitable for your normal skin, this serum utilizes multiple protein ingredients like Oat Extract Protein and Rice Seed Protein to provide excellent barrier repair and emollient actions, offering great hydration and elasticity.
- While it addresses general skincare needs effectively, it lacks specialized ingredients to directly target your wrinkles and fine lines, meaning its benefits for collagen production or wrinkle reduction are supportive rather than primary.
- The safety profile is excellent, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing components like hydrolyzed corn protein and hydrolyzed milk protein.
How to apply
- Use your moisturizer twice a day in your AM and PM routines. Apply it daily to help smooth fine lines.
- Apply this product after your toner and serum, but before your SPF in the morning. Follow your cleanser and toner steps to keep your skin balanced.
- Gently press a small amount into your face and neck. Avoid rubbing the skin too harshly to prevent extra tension.
- Apply the moisturizer on slightly damp skin to help lock in extra moisture. Clean skin helps the product absorb much more evenly.
- Avoid the sensitive eye area during application. Do a quick patch test before your very first use to stay safe.
