Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your normal skin, as salicylic acid and lactic acid help to clear pores and reduce blemishes, while glycerin provides essential hydration.
- While beneficial for acne-prone skin, the formula lacks specialized ingredients to effectively target your pigmentation concerns.
- The product is safe for your normal skin, with no reported risks of irritation due to the absence of harsh or prohibited 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.

Clinical, Cosmetic and Investigational Dermatology, 2017BioMed Research International, 2020
What does Salicylic Acid do for skin with dark spots?
Salicylic acid helps fade dark spots and uneven skin tone left behind after breakouts. It gently clears away surface buildup, which may improve the look of dark marks and support a smoother, more even complexion over time.
What does Willow Bark Extract do for skin with dark spots?
Willow bark extract is unlikely to directly fade dark spots, but it helps clear away dead skin and calm redness for a more even tone. To properly target dark spots, this skin type needs brighteners like vitamin C or niacinamide alongside gentle exfoliants.
Where does this treatment go in a skincare routine for skin with dark spots?
This treatment goes in the evening routine, applied after your cleansing toner and before your moisturizer. A product of this type for skin with dark spots needs added brightening ingredients to properly target your pigmentation concerns.
Can I use this treatment with retinol, and in what order?
You can use this treatment with retinol by applying the treatment in your PM routine before your moisturizer, and using your retinol on alternate nights to prevent excess dryness or irritation. This formula helps clear pores with salicylic acid and lactic acid while glycerin keeps your skin soft, but combining active treatments too often may increase sensitivity.
How often should I use this treatment?
Use this treatment in your evening routine once a week to start, and you may carefully use it more often if your skin tolerates it well and shows good results. For skin with dark spots, this product type needs specialized ingredients that target pigmentation along with exfoliating acids to keep your skin smooth and even-toned.
Can this treatment clog pores, cause breakouts or purging for skin with dark spots?
This treatment is unlikely to clog pores or cause breakouts for your skin, as salicylic acid helps to clear pores. However, because it lacks specialized ingredients to fade dark spots, this skin needs targeted brightening ingredients like vitamin C or niacinamide for better results.
Is this treatment fragrance-free and alcohol-free?
It contains fragrance (farnesol) and drying alcohol (alcohol denat).
