Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Excellent suitability for your normal skin is provided by Saccharomyces Ferment Filtrate and Glycerin, which offer superb humectant action and barrier repair, addressing your concerns about wrinkles and fine lines.
- Niacinamide and Adenosine further promote skin rejuvenation and improve elasticity, enhancing the product's benefits for your skin.
- The product is safe for your normal skin due to the absence of harsh ingredients and the inclusion of soothing Centella Asiatica Extract and Chamomilla Recutita Flower Extract.
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.

What does Hyaluronic Acid do for mature skin?
Hyaluronic acid helps mature skin by deeply boosting moisture, improving elasticity, and smoothing the appearance of fine lines and wrinkles. Regular use keeps the skin looking plump and soft while supporting overall firmness and hydration.
Journal of Drugs in Dermatology, 2011Skin Research and Technology, 2024
Where does it go in a skincare routine for mature skin?
This moisturizing treatment goes in the evening routine after cleansing and before moisturizing. Treatments with active ingredients are placed in the evening for simplicity and extra safety around sun exposure.
Can I use this treatment with retinol, and in what order?
Yes, you can use this treatment with retinol by applying the treatment first to hydrate and soothe your skin before adding retinol. Using a barrier-supporting moisturizer alongside retinol helps reduce dryness and irritation while improving overall treatment comfort.
How often should I use it?
You can use this treatment in your evening routine, applying it after your cleansing toner and before your moisturizer. Daily use helps keep mature skin smooth and hydrated while improving the look of fine lines and wrinkles over time.
Journal of Cosmetic Dermatology, 2020Health Science Reports, 2021
Can this treatment clog pores, cause breakouts or purging for mature skin?
This moisturizing treatment is unlikely to clog pores or cause breakouts for mature skin, as it is free from harsh ingredients and includes soothing plant extracts that help keep skin calm and balanced. It does not cause skin purging since it works to hydrate and soften rather than speed up cell turnover.
Can I use it around the eyes or on my body?
This moisturizing treatment is well-suited for the face, but the thin skin around the eyes and on the body often requires specific formulations that address localized concerns like extreme thinness or dryness. Ingredients like Sodium Hyaluronate and Centella Asiatica Extract help keep skin hydrated and calm, making gentle application possible if your skin tolerates it well.
Is this treatment fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
