Lovi Assistant explains
- Suitable for normal skin, this serum contains glycerin and niacinamide to provide hydration and support your skin barrier. Palmitoyl Hexapeptide-19 and Palmitoyl Tripeptide-38 offer moderate firming benefits by plumping the skin and minimizing fine lines.
- While it provides general skincare benefits like hydration from sea water, it does not specifically target your main concern of pigmentation.
- The product is safe for your normal skin, with no reported risks of irritation due to the absence of harsh ingredients.
How to apply
- Apply this serum as part of your PM routine starting 3x/week and build up to daily use if your skin likes it.
- Place the serum after cleansing and toning, but before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and wait a minute for it to absorb.
- Apply the serum on dry skin to help fade pigmentation effectively.
- Avoid the eye area and always use SPF 30+ during the day.

Questions and answers
How well does DIME Super Firm Serum work for skin with dark spots?
DIME Super Firm Serum works for skin with dark spots only moderately well, as it hydrates and firms the skin but does not specifically target your main concern of dark spots. A product for this skin needs a blend of effective antioxidants and soothing ingredients that provide significant benefits for pigmentation concerns without any risk of irritation.
Journal of Cosmetic Dermatology, 2021Clinical, Cosmetic and Investigational Dermatology, 2017
Which ingredients make this serum a good fit for skin with dark spots?
Niacinamide helps make this serum a fit for your skin with dark spots by supporting your skin barrier and improving skin tone. Treatments that fit this skin better need potent antioxidants and soothing ingredients that specifically target dark spots safely.
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.
What does Palmitoyl Hexapeptide-19 do for skin with dark spots?
This product type needs brightening ingredients and antioxidants to effectively help fade dark spots and even out skin tone.
Where does it go in a skincare routine for skin with dark spots?
This serum goes in your evening routine as a treatment step, applied after cleansing and before moisturizing. While it hydrates and helps firm your skin, dark spots require a product of this type that also includes targeted brightening ingredients like vitamin C or retinoids.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first to give your skin hydration and firming benefits, followed by your retinol. This product is unlikely to irritate normal skin due to its gentle ingredients, but a dark spots routine works best with targeted brightening ingredients like vitamin C or alpha arbutin.
How often should I use it?
This treatment serum goes in your evening routine, used once a day for safety around sun exposure. Because it does not specifically target dark spots, this skin needs a product with brightening ingredients like vitamin C or alpha arbutin to fade discoloration.
Can this serum clog pores, cause breakouts or purging for skin with dark spots?
This serum is unlikely to clog pores or cause breakouts on your skin, as it is free of harsh ingredients and safe for normal skin. To properly address dark spots, a product of this type needs targeted brightening ingredients that actively fade discoloration.
Is it fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
