iS Clinical Brightening Serum

$76.00 - $130.00

iS Clinical Brightening Serum is a corrective serum that brightens dark spots and diminishes uneven skin tone.

Why We Love It

Hyperpigmentation and melasma are concerns in skincare that can frustrate us. A lot of the solutions are too harsh for folks with sensitive skin (we're looking at you, hydroquinone). Other times, the "solutions" don't do much at all. This is why we like this serum. It ditches the retinol and the full strength acids. Instead, this formula contains potent extracts that are kind to all types of skin. Whether you've got oily skin or dry skin, this will respect your skin.

0.5 fl oz. or 1 fl oz | 3.4 pH +/- 0.5 | Description: Lightweight, clear to light yellow

Paraben-Free | Gluten-Free | Vegan

(This formula's name used to be "iS Clinical White Lightening Serum")

Who Will Love It

All skin types, but particularly sensitive skin types looking to address discoloration gently and holistically.

Recommended Use

After using cleanser and toner, apply 3-4 drops to your hand. Massage and dab gently over your face/neck or specific areas affected by hyperpigmentation. Follow with heavier serum, moisturizer, & SPF/sunscreen.

Key Ingredients

  • Ascophyllum Nodosum Extract (Norwegian Kelp Extract) 2% - This interrupts hyperpigmentation and boosts exfoliation to remove dark spots.
  • Saccharum Officinarum (Sugar Cane) Extract 2% - Gently encourages exfoliation. This is the source of glycolic acid, but less harsh.
  • Vaccinium Myrtillus (Bilberry) Fruit/Leaf Extract 2% - A moisturizing exfoliant, so you get more results without dry skin. Bilberry fruit is the source of lactic acid.
  • Alpha-Arbutin 1% - This inhibits tyrosinase enzymes that create melanin. This means less dark spots and blemishes.
  • Salix Alba (Willow) Bark Extract 1% - The source of salicylic acid, this exfoliates and deep cleanses pores.
  • Polyporus Umbellatus (Mushroom) Extract 1% - Stops melanin production and controls bacteria. This extract is the source of kojic acid.
