Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers excellent moisturizing for your normal skin, as hydrolyzed collagen and ceramide NP hydrate and enhance barrier resilience, supporting elasticity and reducing the appearance of wrinkles and fine lines.
- Niacinamide and adenosine further contribute to skin health by improving tone and providing anti-aging benefits.
- The formula is safe for your skin, with no reported risks of irritation due to the absence of harsh or prohibited ingredients.
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.
People Say
★4.6Overall rating based on 200+ reviewsUsers consistently praise this serum for delivering an immediate "glass skin" finish and deep hydration, making it particularly effective for dry, dull, or mature skin types. The innovative twist-click packaging and milk protein formula are hits for their hygienic and smoothing properties, though some users find the 15ml quantity too small for the price and the texture slightly too sticky for oily skin.
