Serums

Serums can be an optional step between cleansing and moisturizing. Start with one product suited to your needs, check its full ingredient list and introduce new formulas gradually.

Which REK serum or treatment is right for me?

• Hydrated, refreshed-feeling skin: Niacinamide & Hyaluronic Acid Hydrating Face Serum includes niacinamide, glycerin, sodium hyaluronate and hydrolyzed hyaluronic acid, alongside jojoba and botanical extracts.
• Uneven-looking tone and dullness: The Dark Spot Skincare Duo pairs Pigment Perfecting and Vitamin C serums in a coordinated two-serum set. Check each bottle's directions.
• Uneven-looking texture: Consider the 3.5% Glycolic Acid Liquid Exfoliator as an occasional evening treatment, not a daily hydrating serum.

How to layer a simple skincare routine

First use a suitable cleanser; apply the serum as directed; finish with a moisturizer. Use broad-spectrum SPF 30 or higher sunscreen during the day. Sensitive skin? Introduce products one at a time and avoid combining several exfoliating treatments in one routine.
