Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate suitability for your normal skin due to the presence of multiple forms of hyaluronic acid for humectant action, but lacks sufficient emollient ingredients for optimal hydration.
- While the serum provides excellent moisturizing benefits relevant for general skincare, these are not directly targeted at your main goal of pigmentation.
- The product is safe for your normal skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
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.

It effectively plumps the skin and serves as an excellent makeup primer. A very large amount of data was used to generate this summary, and it should be definitely taken into account.

Questions and answers
How well does MERIT Great Skin Instant Glow Serum work for skin with dark spots?
This serum works moderately well for your skin, as it brings in good moisture but lacks targeted ingredients for dark spots. A moisturizing treatment for this skin needs ingredients that provide strong hydration and help fade dark spots without causing irritation.
Dermatologic Therapy, 2022Journal of Pharmacy & Pharmaceutical Sciences, 2015
Which ingredients make this serum a good fit for skin with dark spots?
This serum is an average fit for skin with dark spots because, while it contains niacinamide and multiple forms of hyaluronic acid to help keep skin smooth, it lacks enough softening ingredients to fully support your skin goals. A moisturizing treatment for skin with dark spots needs ingredients that deeply hydrate and actively target pigmentation without causing irritation.
Dermatologic Therapy, 2022Journal of Pharmacy & Pharmaceutical Sciences, 2015
What does Hyaluronic Acid do for skin with dark spots?
Hyaluronic acid is unlikely to directly fade dark spots, but it helps keep dry and uneven skin plump and deeply hydrated. To effectively target dark spots, this type of skin needs brightening ingredients like vitamin C or niacinamide alongside your hydrator.
What does Niacinamide do for skin with dark spots?
Niacinamide helps fade dark spots and uneven pigmentation by slowing down the transfer of pigment in the skin. It is generally well tolerated and may improve overall skin brightness with consistent use.
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, though it is an average fit for skin with dark spots because it lacks targeted brightening ingredients and rich softening ingredients for optimal hydration.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first to help hydrate your skin before putting on your retinol. This product is safe for your skin with no risks of irritation, though a product for dark spots needs targeted brightening ingredients like vitamin c or kojic acid to better address pigmentation.
How often should I use this serum?
You can use this serum daily, as it is safe for your skin, though it does not specifically target dark spots. Skin with dark spots needs products that include brightening ingredients and extra softening ingredients to help fade discoloration and lock in moisture.
Journal of Cosmetic Dermatology, 2020Health Science Reports, 2021
Can this serum clog pores, cause breakouts or purging for skin with dark spots?
This serum is unlikely to cause breakouts or clog pores on skin with dark spots because it is safe for normal skin and has no harsh ingredients. However, it does not target pigmentation directly and lacks rich softening ingredients for optimal moisture, so this skin needs ingredients like vitamin C or alpha arbutin to fade dark spots and heavier moisturizers to seal in hydration.
Dermatologic Therapy, 2022Journal of Pharmacy & Pharmaceutical Sciences, 2015
Can I use this serum around the eyes or on my body?
You can safely use this serum around the eyes and on the body because it has a very safe profile with no harsh ingredients, though the eyelid is naturally thinner than other areas. A product for the delicate eye area or body needs rich soothing ingredients and deep moisturizers to keep those thinner spots soft and smooth.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
