Lovi Assistant explains
- Offers moderate exfoliation for pigmentation and texture refinement suitable for your normal skin, as mandelic acid and retinol promote skin renewal and cell turnover.
- The formula provides basic hydration and nourishment, though additional humectants could enhance overall comfort for normal skin.
- The product is generally safe for your skin, with minimal risks of irritation from mandelic acid and retinol.
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 The INKEY List Mandelic Acid work for skin with dark spots?
This treatment works for skin with dark spots by using mandelic acid and retinol to help renew the skin and fade dark spots, though other products fit this skin better. A product for this skin needs strong antioxidants and soothing ingredients to help clear dark spots without causing irritation, along with extra hydrating ingredients.
Which ingredients make this exfoliant a good fit for skin with dark spots?
Mandelic acid and retinol make this treatment a good fit because they help fade dark spots by promoting skin renewal and cell turnover. To work best for dark spots, a treatment for this skin type needs potent antioxidants, soothing ingredients like niacinamide and propolis, and extra hydrating components to keep skin comfortable.
What does Mandelic Acid do for skin with dark spots?
Mandelic acid helps fade dark spots and uneven skin tone while being generally gentle on the skin. It works by gently exfoliating the outer layer to reveal fresher, more even skin underneath. To properly treat dark spots, a product of this type needs additional brightening ingredients and soothing agents to calm the skin and improve pigment reduction.
What does Glycerin do for skin with dark spots?
Glycerin helps keep dry skin hydrated and supports a healthy skin barrier, which makes skin feel soft and smooth. While it does not directly fade dark spots on its own, it is often added to spot-fading products to keep the skin comfortable while other ingredients work.
Clinical, Cosmetic and Investigational Dermatology, 2017Acta Dermato-venereologica, 2017
Where does it go in a skincare routine for skin with dark spots?
This treatment goes in the evening routine after cleansing and before moisturizing, starting once a week and slowly using it more often if your skin tolerates it well. Skincare for dark spots of this type also needs extra hydrating ingredients to keep normal skin fully comfortable.
Can I use this exfoliant with niacinamide, and in what order?
You can use this treatment with niacinamide by applying niacinamide first and letting it absorb before putting on this formula. This routine helps brighten dark spots and refine texture while keeping skin comfortable, though this skin type needs extra hydrating ingredients to prevent dryness.
How often should I use it?
Start by using this treatment once a week in the evening, and if your skin feels comfortable, you can carefully use it more often. This product needs extra hydrating ingredients to boost comfort and better address dark spots on normal skin.
Can this exfoliant clog pores, cause breakouts or purging for skin with dark spots?
This treatment is unlikely to clog pores, but the mandelic acid and retinol in it help speed up cell turnover, which may cause some initial purging on skin with dark spots. A product of this type needs reliable exfoliating acids and soothing hydrators to help clear dark spots while keeping normal skin comfortable.
Is it fragrance-free and alcohol-free?
It has no drying alcohol and contains fragrance (benzyl alcohol). Cetearyl alcohol is a fatty alcohol, which soften the skin.
What the research says
Topical bakuchiol 0.5% applied twice daily compared with retinol 0.5% applied daily significantly decreased wrinkle surface area and hyperpigmentation with no statistical difference between the compounds in 44 patients over 12 weeks, while retinol users reported more facial skin scaling and stinging.
The British Journal of Dermatology, 2019Topical 0.4% retinol significantly increased epidermal thickness, dermal vascularity, and extracellular matrix production by stimulating keratinocyte proliferation, endothelial cell proliferation, and fibroblast activation in naturally aged human skin compared to vehicle.
International Journal of Cosmetic Science, 2017A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.
