Lovi Assistant explains
- Suitable for normal skin, this serum utilizes niacinamide and glycerin to provide hydration and support the skin barrier, with niacinamide also offering some anti-inflammatory benefits for redness.
- The formulation includes sodium ascorbate and various botanical extracts that contribute to brightening and evening skin tone, though it lacks ingredients specifically targeting significant improvement for irritation.
- The product is safe for your sensitive skin, as it contains no harsh or prohibited ingredients that would cause irritation.
How to apply
- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
- Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
- Always do a patch test before your first use and avoid getting the serum too close to your eyes .

Questions and answers
How well does PCA Skin Vitamin B3 Brightening Serum work for sensitive skin?
PCA Skin Vitamin B3 Brightening Serum is a safe, average fit for sensitive skin that helps hydrate and calm redness using niacinamide and glycerin. Because it lacks ingredients that specifically target irritation, treatments that fit sensitive skin better need soothing ingredients that directly calm and relieve redness and irritation.
Which ingredients make this serum a good fit for sensitive skin?
This serum is a fair fit for sensitive skin because niacinamide and glycerin help hydrate and support the skin barrier while calming redness. However, because it lacks ingredients that actively target irritation, a product of this type needs calming botanical extracts and barrier-repairing agents to properly care for sensitive skin.
What does Niacinamide do for sensitive skin?
Niacinamide helps calm sensitive skin by strengthening the skin barrier and reducing redness and irritation. It is very well tolerated and may improve overall comfort and resilience with regular use.
What does Glycerin do for sensitive skin?
Glycerin helps keep sensitive skin soft and deeply hydrated while supporting the skin barrier. It is unlikely to cause irritation and may protect against dryness and roughness.
The British Journal of Dermatology, 2008Acta Dermato-venereologica, 1999
Where does this serum go in a skincare routine for sensitive skin?
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first in your evening routine and following with a moisturizer, as this product is safe for your sensitive skin. However, since this formulation lacks ingredients that actively calm irritation, sensitive skin types dealing with retinoids need a product that additionally includes soothing plant extracts and barrier-supporting hydrators.
How often should I use this serum?
This serum can be used in the evening as part of your routine. It is safe for sensitive skin and hydrates while helping with redness, though a sensitive skin type works best with products that also specifically target and calm irritation.
Can this serum clog pores, cause breakouts or purging for sensitive skin?
This serum is unlikely to clog pores or cause breakouts on sensitive skin because it contains no heavy oils or pore-clogging ingredients. It is also unlikely to cause purging since it lacks strong exfoliating acids.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
