Lovi Assistant explains
- Excellent suitability for your normal skin is provided by Camellia Sinensis Leaf Extract and Niacinamide, which offer antioxidant activity and barrier repair, addressing your wrinkles and fine lines by promoting collagen production and antioxidant protection.
- Adenosine and Epigallocatechin Gallate further enhance these benefits by promoting collagen production and providing antioxidant protection, contributing to improved skin tone and hydration.
- The product is safe for your skin due to the absence of harsh ingredients and the inclusion of soothing agents like Camellia Sinensis Leaf Extract and Allantoin.
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.
