Lovi Assistant explains

  • Offers moderate suitability for your dry skin as glycerin and betaine provide essential hydration and improve your skin barrier function, while niacinamide helps to even skin tone and reduce blemishes.
  • The formula is safe for your dry skin, lacking harsh ingredients and including soothing components to prevent irritation.
  • While beneficial for hydration and texture, the product could offer more emollient ingredients for truly optimal results on dry skin.

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.

Questions and answers

How well does Good Molecules Niacinamide Serum work for dry skin?

Good Molecules Niacinamide Serum works moderately well for dry skin, as glycerin and betaine provide essential moisture while niacinamide helps even skin tone, though a product of this type needs richer, softening ingredients and barrier-supporting components like ceramides or peptides for truly optimal results.

Skin Research and Technology, 2003

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

Glycerin and betaine make this serum a fit for your dry skin by providing essential hydration and improving your skin barrier function. Niacinamide also helps to even skin tone and reduce blemishes. A treatment of this type needs richer rich moisturizing ingredients and skin-softening oils to give truly optimal results for dry skin.

Skin Research and Technology, 2003

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 Glycerin do for dry skin?

Glycerin helps dry skin by drawing in moisture and keeping it locked in, which makes the skin feel much softer and smoother. It also supports your natural skin barrier to stop water from escaping easily. A product for dry skin needs extra ingredients like hyaluronic acid and soothing plant extracts to truly calm and hydrate dry patches.

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

This serum goes in your evening routine, applied after cleansing and before your moisturizer. Treatments are placed in the evening for simplicity and extra safety around sun exposure.

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

You can use this serum with retinol by applying the serum first and following it with your retinol product. This helps keep your skin comfortable and hydrated while you use retinol, though dry skin truly needs richer, softening ingredients to get the best results.

How often should I use it?

You can use this treatment in the evening as part of your routine. It works for dry skin by providing hydration and soothing components, though a dry skin type needs extra rich, softening ingredients to reach truly optimal results.
