Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate hydration for your wrinkles and fine lines, as Beta-Glucan and Sodium PCA provide humectant action to support moisture retention in your normal skin.
- The serum also enhances barrier resilience, which is beneficial for maintaining overall skin health.
- The product is safe for your normal skin, with no risks of irritation due to the absence of harsh ingredients and the presence of soothing Beta-Glucan.
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.

Questions and answers
How well does iUNIK Beta-Glucan Power Moisture Serum work for mature skin?
This serum works moderately well for mature skin, offering moderate hydration for wrinkles and fine lines while helping support barrier resilience. It is safe for normal skin and is unlikely to cause irritation. A product of this type for mature skin needs potent anti-aging ingredients, rich emollients and humectants, and peptides, antioxidants, or probiotics to properly nourish the skin and address wrinkles and fine lines.
Journal of Cosmetic Dermatology, 2021Scientific Reports, 2023
Which ingredients make this serum a good fit for mature skin?
Beta-glucan and sodium PCA make this serum a good fit for mature skin by drawing in moisture to help smooth out the look of fine lines and wrinkles. This serum needs rich moisturizers, peptides, and antioxidants to give mature skin the best nourishment and care.
What does Beta-Glucan do for mature skin?
Beta-glucan helps mature skin by boosting hydration, smoothing fine lines, and supporting the skin barrier. It also provides antioxidant protection and encourages skin repair, making it a great addition to anti-aging routines.
What does Sodium PCA do for mature skin?
Sodium PCA helps keep mature skin feeling soft and smooth by drawing in moisture to improve dryness. Formulations with this ingredient help maintain skin hydration and support overall comfort.
Where does this serum go in a skincare routine for mature skin?
This serum goes in the evening routine after your cleansing toner and before your moisturizer. Mature skin also benefits from ingredients like antioxidants, peptides, and retinoids to better target fine lines and firmness.

Can I use this serum with niacinamide, and in what order?
You can use this serum with niacinamide by applying niacinamide first and then this moisturizing treatment to lock in hydration. This approach is unlikely to cause irritation and helps support overall skin health. A better fit for mature skin would be a richer product that provides deeper hydration for fine lines and wrinkles using heavy nourishing oils and firming peptides.
How often should I use this serum?
You can use this serum in the evening as part of your routine. For mature skin, a product of this type needs richer anti-aging ingredients and deep moisturizers like peptides, retinoids, or ceramides to better smooth fine lines and plump dry areas.
Can this serum clog pores, cause breakouts or purging for mature skin?
This serum is unlikely to cause breakouts or clog pores for your mature skin, as reviewers rarely report these issues and the formula lacks heavy, pore-clogging ingredients. To better smooth and deeply hydrate mature skin, a product of this type needs richer moisture-locking ingredients like plant oils or butters.
Can I use this serum around the eyes or on my body?
This serum is safe to use around your eyes and on your body, as its gentle ingredients are unlikely to cause irritation. Because the skin around your eyes is thinner, this product helps provide moderate hydration, but mature skin typically needs richer creams with peptides, retinoids, or rich oils to better smooth fine lines and wrinkles.
