Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening and hydration for dry or flaky skin due to niacinamide and glycerin, but alcohol denat may worsen dryness and sensitivity.
- Phenylethyl resorcinol contributes to evening skin tone, though the formula lacks sufficient emollient ingredients like dimethicone for adequate smoothing of intercellular lipids on dry skin.
How to apply
- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

Questions and answers
Why is La Roche-Posay Pure Niacinamide 10 Serum a weak match for dry sensitive skin?
This serum is a weak match for dry sensitive skin because alcohol denat may worsen dryness and irritation, while lacking enough heavy moisturizing ingredients and skin-softening agents to properly smooth and protect dry skin. A product of this type needs rich moisturizing ingredients like ceramides and extra hydrators to soothe dry skin and protect its barrier safely without irritation.
Which ingredients make this serum a poor fit for dry sensitive skin?
Alcohol denat may worsen dryness and sensitivity on your skin, and the formula lacks sufficient rich moisturizers and skin-softening ingredients to properly smooth and protect dry skin.
What does Niacinamide do for dry sensitive skin?
Niacinamide helps dry sensitive skin by calming irritation and keeping moisture locked in so your face feels soft and smooth. It works to build up your skin barrier and calm redness while being very gentle and unlikely to cause irritation.
Journal of Cosmetic Dermatology, 2004International Journal of Pharmaceutics, 2013
What does Thermal Water do for dry sensitive skin?
Thermal Water helps calm dry sensitive skin by reducing redness and soothing irritation. It is unlikely to cause irritation and may support a more comfortable feel for reactive skin types.
Journal of the European Academy of Dermatology and Venereology, 2020Journal of the European Academy of Dermatology and Venereology, 2011
Where does this serum go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine after your cleansing and toning steps, followed by a rich moisturizer. Because this product is a weak match that may worsen dryness and sensitivity, dry sensitive skin needs a product of this type with soothing, deeply moisturizing ingredients and rich skin-softening oils to keep the skin calm and comfortable.
Can I use it with retinol, and in what order?
You can use this serum with retinol by applying the retinol first at night, letting it absorb, and then following with a rich moisturizer to prevent dryness and irritation. This type of skin needs hydrating ingredients like glycerin and soothing emollients to keep the skin barrier smooth and calm.
How often should I use this serum?
You can use this treatment serum in the evening. A product of this type needs soothing and rich moisturizing ingredients like glycerin and heavy softeners to keep dry and sensitive skin calm and comfortable.
Can it clog pores, cause breakouts or purging for dry sensitive skin?
La Roche-Posay Pure Niacinamide 10 Serum is unlikely to clog pores or cause breakouts on dry sensitive skin, as reviewers rarely report this issue. However, because this product is a weak match for your skin, a suitable alternative needs extra hydrating and soothing ingredients like glycerin and thermal water to keep dry skin calm and smooth.
Is this serum fragrance-free and alcohol-free?
It contains fragrance (parfum) and drying alcohol (alcohol denat).
