Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening and evening of skin tone due to niacinamide and phenylethyl resorcinol, but its alcohol denat content may be drying for your dry skin, and it lacks sufficient emollients to fully address dryness.
  • While it provides some hydration with glycerin and sodium hyaluronate, the formula's overall balance is suboptimal for your specific dry skin needs.

How to apply

  • Apply this serum PM, starting 3×/week and working up to daily use as your skin adjusts.
  • Place the serum after cleansing and toner, but right before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
  • Apply the serum on slightly damp skin to help lock in extra moisture.
  • Avoid the eye area and do a patch test before your first use.

People Say

★4.5Overall rating based on 1.1k+ reviews

Based on a very large amount of data, this serum is highly praised for its ability to fade dark spots and improve skin texture, leaving skin feeling hydrated and plump. Many users with sensitive skin find it gentle. A significant number of reviewers dislike the strong floral fragrance and find the dropper bottle design inconvenient. Some users have experienced breakouts or pilling, and many note that the product is now discontinued or difficult to find.

Questions and answers

Why is La Roche-Posay Pure Niacinamide 10 Serum a weak match for dry skin?

La Roche-Posay Pure Niacinamide 10 Serum is a weak match because its alcohol content may be drying for your dry skin, and it lacks sufficient nourishing and rich moisturizing ingredients to fully address dryness. A treatment for dry skin needs plenty of hydrating ingredients and barrier-supporting components like ceramides or soothing plant extracts to keep skin soft and comfortable.

Clinical, Cosmetic and Investigational Dermatology, 2017

Which ingredients make this serum a poor fit for dry skin?

This serum contains alcohol denat, which may dry out your dry skin, and it lacks enough richer ingredients to fully handle dryness. Dry skin of this type needs rich, soothing ingredients, ceramides, peptides, and strong moisturizers that build up the skin barrier and provide deep hydration without any risk of irritation.

What does Niacinamide do for dry skin?

Niacinamide helps dry skin by strengthening the skin barrier, increasing hydration, and reducing water loss. It supports ceramide production and helps keep the surface smooth and calm. This ingredient tends to be very well tolerated and is unlikely to irritate dry skin.

Journal of Cosmetic Dermatology, 2004Journal of Cosmetic Dermatology, 2026

What does Thermal Water do for dry skin?

Thermal water helps boost skin hydration and reduces dryness and stinging while calming the skin. It may also improve overall skin comfort and support your usual routine by keeping the skin calm.

The Medical Journal of Malaysia, 2024

Where does this serum go in a skincare routine for dry skin?

This serum goes in the evening routine for dry skin. A product of this type needs rich moisturizers and nourishing ingredients like ceramides, squalane, or heavier plant oils to keep dry skin soft and smooth.

Can I use this serum with retinol, and in what order?

This serum may be too drying to easily pair with retinol on dry skin because it contains alcohol denat and lacks rich moisturizers. A product of this type needs extra soothing oils and rich butters to keep dry skin soft and comfortable.

How often should I use this serum?

You can use this serum in the evening as part of your routine. However, because it contains drying ingredients and lacks sufficient rich moisturizers for your dry skin, a product of this type needs extra soothing hydrators and heavy smoothing oils to keep your skin soft and comfortable.

The British Journal of Dermatology, 2002Journal of Cosmetic Dermatology, 2021

Can this serum clog pores, cause breakouts or purging for dry skin?

This serum is unlikely to cause breakouts for dry skin, as negative reviews about clogged pores are rare. However, dry skin needs a product with richer emollients and no drying alcohols to keep the skin feeling soft and comfortable.

Is this serum fragrance-free and alcohol-free?

It contains fragrance (parfum) and drying alcohol (alcohol denat).
