Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening and evening of skin tone for your normal skin due to the presence of tetrahexyldecyl ascorbate and glutathione, which support your main goal of pigmentation. Glycerin and tocopherol provide general skincare benefits like hydration and antioxidant protection, which are supportive but not directly targeted at your primary concern.
  • The formula is highly suitable for normal skin, with ingredients like tetrahexyldecyl ascorbate and ascorbic acid stimulating collagen and providing antioxidant activity.
  • The safety profile is excellent, with no risks of irritation for your normal skin due to the absence of prohibited or 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.

This treatment works moderately well for skin with dark spots, offering some brightening and evening of skin tone while keeping your normal skin calm and hydrated. To get better results for dark spots, this type of product needs a blend of powerful antioxidants, soothing ingredients, and proven brightening components like niacinamide or propolis that target pigmentation more intensively.

Where does this serum go in a skincare routine for skin with dark spots?

This treatment goes in the evening routine after cleansing and before moisturizing, which keeps application simple and safe around sun exposure. Skincare for dark spots generally needs targeted brightening ingredients like vitamin C and antioxidants to help fade spots and even out tone.

Journal of Drugs in Dermatology, 2023

Can I use this serum with retinol, and in what order?

You can use this serum with retinol by applying the retinol first, letting it absorb, and then following with this treatment, or by using retinol on alternate nights to keep your skin calm. This product works for dark spots, but to truly fade them effectively, skin with dark spots needs dedicated brightening ingredients like pure vitamin C and powerful antioxidants.

How often should I use this serum?

This treatment serum works well for evening out skin tone, though skin with dark spots often needs products with more targeted brighteners and antioxidants to see the best results. You can use it in the evening, and a product for this skin needs strong brightening ingredients like kojic acid, alpha arbutin, or niacinamide alongside antioxidants to effectively fade dark spots.

Clinical, Cosmetic and Investigational Dermatology, 2014

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, as reviewers rarely report clogged pores and the formula has a very safe profile. Skin with dark spots typically benefits most from a treatment that combines high-strength brightening ingredients like hydroquinone, kojic acid, or tranexamic acid with reliable gentle exfoliants.

Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Cetyl alcohol is a fatty alcohol, which soften the skin.
