Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and evening of skin tone for your normal skin, as niacinamide and sodium ascorbate work to reduce hyperpigmentation and promote an even complexion. Glycerin and dimethicone provide general hydration and support barrier repair, which are beneficial for normal skin.
- The formula is safe for your normal skin, with niacinamide and Camellia Sinensis Leaf Extract offering soothing benefits and no harsh ingredients.
- While the product provides general skincare benefits like hydration, its primary ingredients are not specifically targeted to address your main goal of pigmentation.
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
What makes PCA Skin Vitamin B3 Brightening Serum a great fit for skin with dark spots?
PCA Skin Vitamin B3 Brightening Serum is a great fit because niacinamide and sodium ascorbate help reduce dark spots and promote an even, bright complexion. Ingredients like glycerin and dimethicone also keep normal skin hydrated and support barrier repair, while being very gentle.
The British Journal of Dermatology, 2002Skin Research and Technology, 2009
Which ingredients make this serum a good fit for skin with dark spots?
Niacinamide and sodium ascorbate make this serum a good fit for skin with dark spots because they help reduce dark spots and even out skin tone. Niacinamide works by blocking pigment transfer in the skin, while the formula also includes soothing green tea extract and mulberry leaf extract.
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 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
