PRODUCT DETAILS

When blemishes leave their mark, this serum keeps the focus on what comes next. Expertrue Toning Serum is made for blemish-prone skin, uneven-looking tone and post-blemish marks. It is separate from the brand's pore-elasticity serum, making it the tone-focused choice in the Expertrue line.

The formula highlights niacinamide, ethyl ascorbyl ether and (-)-alpha-bisabolol as its tone-care trio. That trio supports its focus on helping brighten and even the look of skin affected by blemishes and their marks.

The emulsified serum format is designed for comfortable blemish care, with sensitive skin in mind. Non-comedogenic suitability testing was conducted with acne-prone participants, and a closed-patch test included sensitive-skin participants.

Squalane, beta-glucan and Centella asiatica add complementary moisture care. At an ingredient level, they support softness, hydration and a comfortable feel.
