The formula is lightweight and fast-absorbing to layer into daily routines without stickiness.<\/p>\n<h2>Unique features<\/h2>\n<ul>\n<li>Concentration: This serum contains a 15% niacinamide concentration for targeted tone correction. The title Dr.Althea, 15% Niacinamide Purity Serum, 30ml appears clear and descriptive for shoppers.<\/li>\n<li>Texture: Lightweight, non-greasy serum texture allows quick absorption. The fast-absorbing feel contributes to easy layering with moisturizers and sunscreens.<\/li>\n<li>Formulation: Focused formulation purposefully limits unnecessary additives. The product focuses on clarity and balance rather than heavy fragrance or oils.<\/li>\n<\/ul>\n<h2>Main benefits<\/h2>\n<ul>\n<li>Brightening: Niacinamide helps promote a more even skin tone with consistent use. Regular application contributes to the appearance of reduced dark spots and dullness.<\/li>\n<li>Pore care: The serum supports the appearance of refined pores and balanced sebum. This contributes to a smoother skin surface and improved texture.<\/li>\n<li>Light hydration: Formulated to provide lightweight hydration without heaviness. The serum helps support comfortable skin feel under other products.<\/li>\n<\/ul>\n<h2>Key ingredients<\/h2>\n<ul>\n<li>Niacinamide: Niacinamide (15%) is the core active for brightening and barrier support. The high concentration targets tone and texture concerns.<\/li>\n<li>Humectants: Ingredients such as pentylene glycol and glycerin help draw moisture into the skin. These components contribute to a hydrated, plump appearance without greasiness.<\/li>\n<li>Soothing extracts: Plant-derived extracts and tocopherol provide supportive antioxidant and calming properties. These ingredients contribute to an overall balanced formulation.<\/li>\n<\/ul>\n<h2>How to use<\/h2>\n<ul>\n<li>Application: Apply a few drops to cleansed skin once or twice daily as part of a routine. Gently pat until absorbed and follow with moisturizer.<\/li>\n<li>Layering: Use under sunscreen in the morning and under a moisturizer at night. Avoid combining simultaneously with strong exfoliating acids without testing for sensitivity.<\/li>\n<li>Patch test: Conduct a patch test prior to first use to check tolerance. Discontinue if irritation occurs and consult a professional.<\/li>\n<\/ul>\n<h2>How does it work?<\/h2>\n<ul>\n<li>Mechanism: Niacinamide works to regulate skin barrier function and tone. This contributes to visibly more even, smoother skin over time.<\/li>\n<li>Supportive actives: Humectants and antioxidant components support skin hydration and protection. Together they help maintain comfort during use.<\/li>\n<li>Targeted effect: The concentrated 15% formulation targets areas of uneven tone and excess oil. Repeated use helps support gradual improvement in overall complexion.<\/li>\n<\/ul>\n<h2>Directions for use<\/h2>\n<ul>\n<li>Routine: Use after cleansing and toning, before heavier creams. Apply 2\u20133 drops and spread evenly across the face.<\/li>\n<li>Frequency: Start with once daily if you have sensitive skin, then increase to morning and evening as tolerated. Always follow with sunscreen during daytime use.<\/li>\n<li>Storage: Store in a cool, dry place away from direct sunlight. Keep the cap closed to maintain formula stability.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A lightweight niacinamide serum that helps support brighter, more balanced-looking skin.
