Paula's Choice Clinical Niacinamide 20% Treatment is an innovative serum that helps skin re-learn how to function properly. As ageing skin loses its elasticity, the skin around pores becomes less firm. This causes a sagging effect while pores clogged with oil, dirt and dead skin can become enlarged. Niacinamide is a water soluble ingredient that works within the pore lining to dramatically tighten sagging pores and reduce the look of stubborn, enlarged pores. This treatment is formulated with a higher concentration of ingredients proven to combat advanced ageing concerns to quickly restore skin's youthful bounce and vitality. Key Ingredients :

Niacinamide: 20% niacinamide dramatically tightens and improves the appearance of sagging pores by reducing sebum production, boosts collagen production and increases ceramides in the skin's barrier to improve elasticity.
Meadowsweet: Prevents visible bumps and texture changes by interrupting excess oil-producing triggers
Acetyl Glucosamine: An amino acid sugar that works with niacinamide to refine skin texture
Purslane: Skin soothing, nutrient-rich antioxidant that helps create a healthier complexion

Skin type: Suitable for all skin types. It's even suitable for skin with sebaceous hyperplasia.
