Lovi Assistant explains
- Suitable for normal skin, this serum provides excellent moisturization with Beta-Glucan and Sodium PCA, which hydrate and strengthen your skin barrier.
- While it offers general skincare benefits, it does not contain specialized ingredients to address your pigmentation concerns.
- The formula is safe for your skin, featuring soothing Beta-Glucan and lacking any harsh or irritating components.
How to apply
- Could be used as part of your AM and PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
- Apply this moisturizer after your cleanser and toner, right before your morning SPF.
- Gently press a small amount of the moisturizer into your skin. Avoid rubbing it too hard so it absorbs nicely.
- For the best moisture, you can apply it when your skin is slightly damp. This helps your skin stay soft and happy.
- Remember to avoid the eye area when applying. Always do a patch test before your first use.

Questions and answers
How well does iUNIK Beta-Glucan Power Moisture Serum work for skin with dark spots?
This serum works moderately well for your skin, providing good moisture with Beta-Glucan and Sodium PCA, but it lacks specialized ingredients to fade dark spots. A product for this skin needs effective brightening agents alongside hydrating components to target pigmentation concerns while keeping skin balanced.
Which ingredients make this serum a good fit for skin with dark spots?
This serum is a fair fit for skin with dark spots because it hydrates and strengthens your skin barrier with Beta-Glucan and Sodium PCA, though it lacks specialized ingredients to fade dark spots. A moisturizing treatment for skin with dark spots needs effective brightening ingredients that address pigmentation goals while keeping your skin calm and hydrated.
What does Beta-Glucan do for skin with dark spots?
Beta-glucan is unlikely to directly fade dark spots, but it helps keep skin calm, deeply moisturized, and protected while you use brightening treatments. It supports your skin barrier so it stays smooth and healthy.
What does Sodium PCA do for skin with dark spots?
Sodium PCA helps keep your skin hydrated and smooth, supporting a more even look over time. While it is great for moisture, dark spots specifically need ingredients that brighten tone and fade discoloration.
Where does this serum go in a skincare routine for skin with dark spots?
This serum goes in the evening routine after cleansing and before moisturizing. While it provides good hydration and strengthens your skin barrier safely, skin with dark spots needs treatments containing specialized brightening ingredients like vitamin C or niacinamide.
Can I use this serum with niacinamide, and in what order?
You can use this serum with niacinamide by applying niacinamide first and following with this hydrating serum. The formula is safe and gentle for your skin.
How often should I use this serum?
This serum works well in the evening as part of your routine for skin with dark spots, and it is safe for daily use. While it provides good moisture and strengthens your skin barrier, this skin needs ingredients that specifically target dark spots to get the best results.

Can this serum clog pores, cause breakouts or purging for skin with dark spots?
This serum is unlikely to cause breakouts for skin with dark spots because the formula is safe and lacks harsh or irritating components. To properly care for dark spots, a product of this type needs specialized brightening ingredients like vitamin C or niacinamide alongside good hydrators.
