  • Allantoin and panthenol further enhance skin comfort and texture, contributing to a smoother complexion.
  • The formula is safe for your normal skin, as it contains soothing ingredients and lacks harsh or prohibited substances.

How to apply

  • Use your exfoliant PM once a week to start, moving up to twice a week if your skin likes it. Always apply SPF during the day while using this product.
  • Apply this exfoliant step right after your cleanser and toner, and before your moisturizer.
  • Gently press 2-3 drops of the exfoliant into your skin and let it dry. Avoid rubbing your face hard.
  • Apply the product on clean, completely dry skin to make sure it works best for your pigmentation goals.
  • Remember to avoid the delicate eye area and do a quick patch test before using it for the first time.

Questions and answers

What makes Good Molecules Mandelic Acid Serum a great fit for skin with dark spots?

Good Molecules Mandelic Acid Serum is a great fit because mandelic acid gently renews your skin to fade dark spots and improve tone, while hyaluronic acid, glycerin, panthenol, and allantoin keep your skin hydrated, calm, and smooth.

American Journal of Clinical Dermatology, 2002The Journal of Dermatological Treatment, 2017

Which ingredients make this serum a good fit for skin with dark spots?

Mandelic acid is the key ingredient that makes this serum a great fit for dark spots by offering moderate exfoliation to improve skin tone, while hyaluronic acid, glycerin, panthenol, and allantoin support hydration and comfort. These soothing additions help keep normal skin calm while the exfoliating acid works to renew the skin.

American Journal of Clinical Dermatology, 2002

What does Mandelic Acid do for skin with dark spots?

Mandelic acid helps fade dark spots and uneven skin tone while being generally gentle on the skin. It works by gently exfoliating the outer layer to reveal fresher, more even skin underneath. To properly treat dark spots, a product of this type needs additional brightening ingredients and soothing agents to calm the skin and improve pigment reduction.

Journal of Cosmetic Dermatology, 2016

What does Hyaluronic Acid do for skin with dark spots?

Hyaluronic acid is unlikely to directly fade dark spots, but it helps keep dry and uneven skin plump and deeply hydrated. To effectively target dark spots, this type of skin needs brightening ingredients like vitamin C or niacinamide alongside your hydrator.

Where does this serum go in a skincare routine for skin with dark spots?

This serum goes in your evening routine after cleansing and before moisturizing. Putting treatments in the evening helps keep your skin safe from sun exposure while it works on dark spots.

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

You can use this serum with retinol by applying them on alternate nights to help prevent dry or irritated skin, as combining two strong treatments at once may be too harsh. When using both, always follow with a good moisturizer to keep your skin feeling soft and comfortable.

American Journal of Clinical Dermatology, 2002The Journal of Dermatological Treatment, 2017

How often should I use this serum?

Start by using this treatment once a week in the evening, and if your skin tolerates it well and you see good results, you can carefully use it more often. This helps reduce dark spots and smooths your complexion while keeping your skin comfortable.

Journal of Cosmetic Dermatology, 2021Journal of Cosmetic Dermatology, 2024

Can this serum clog pores, cause breakouts or purging for skin with dark spots?

This serum is unlikely to cause breakouts, as reviewers rarely report them and the formula contains soothing ingredients that keep skin calm. Mandelic acid helps clear dark spots by promoting skin renewal, though any new exfoliant may occasionally cause mild initial purging.

American Journal of Clinical Dermatology, 2002

Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
