Lovi Assistant explains
- Offers moderate antioxidant protection and mild exfoliation suitable for your normal skin due to the presence of ascorbic acid and lactic acid.
- While the formula provides general skincare benefits, the concentrations of ascorbic acid and ginkgo biloba leaf extract are not optimized to directly address your primary concern of pigmentation.
- The product is safe for your normal skin, with no identified risks of irritation from harsh or prohibited ingredients.

- Gently press 2-3 drops of the serum into your skin and wait a minute for it to absorb.

Questions and answers
How well does ISDIN Flavo-C work for skin with dark spots?
ISDIN Flavo-C Serum is an average fit for skin with dark spots because its ingredients provide mild antioxidant protection and gentle exfoliation, though their amounts are not fully optimized for tackling pigmentation. A treatment for this skin needs a blend of powerful antioxidants, soothing ingredients, and skin-brightening components like niacinamide and propolis to deliver optimal results safely.
Which ingredients make this serum a good fit for skin with dark spots?
Ascorbic acid and lactic acid make this serum a fit for your skin by providing antioxidant protection and mild exfoliation. However, this skin needs a product with a higher concentration of ascorbic acid and ginkgo biloba, along with ingredients like niacinamide and propolis, to effectively address dark spots.
What does Vitamin C do for skin with dark spots?
Vitamin C helps fade dark spots and brightens uneven skin. It works by slowing down pigment production and boosting overall skin clarity.
What does Ginkgo Biloba Extract do for skin with dark spots?
Ginkgo Biloba Extract helps target dark spots by slowing down the enzyme that produces excess skin pigment. This plant extract is unlikely to irritate skin and may brighten your complexion over time with regular use.
Where does this serum go in a skincare routine for skin with dark spots?
This treatment goes in the evening routine after cleansing and toning, and before moisturizing. Dark spots need a product with optimized concentrations of vitamin C and plant extracts designed to directly fade discoloration.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying this treatment first and following with your retinol on separate nights or spaced apart to keep your normal skin calm. Because both products work actively on your skin, alternating them or introducing them slowly helps prevent irritation.
How often should I use this serum?
You can use this treatment in the evening as part of your routine, starting once a week to see how your skin reacts. Since it is well tolerated by normal skin, you may carefully use it more often over time if you see good results.
Can this serum clog pores, cause breakouts or purging for skin with dark spots?
This serum is unlikely to clog pores or cause breakouts for your skin. It has a very low risk of irritation and features mild exfoliation to help keep skin smooth, but a product for dark spots needs higher concentrations of brightening ingredients like ascorbic acid to truly fade them.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
