10% Niacinamide: As a water-soluble vitamin B3 derivative, it has excellent skin permeability and bioavailability, making it a multifunctional skincare ingredient.
1% Zinc PCA: a natural mineral derivative that combines regulating and soothing properties.
（2） Core efficacy
Balancing sebum secretion: Zinc PCA can directly regulate sebaceous gland activity, reduce visible oil on the face, and niacinamide can assist in improving sebum secretion rhythm, especially suitable for areas with strong oil production in the T zone.
Improving skin texture: Niacinamide can promote normal renewal of the stratum corneum, reduce roughness and uneven texture, and combined with zinc PCA, make the skin feel smoother.
Strengthening the skin barrier: Niacinamide can support the synthesis of ceramides and fatty acids, reduce the loss of moisture through the epidermis, and enhance the skin's resistance to environmental stimuli.
Brightening and smoothing skin tone: By blocking melanin transport, niacinamide can improve dullness and fade red brown acne scars. Long term use can enhance skin transparency.
Refine pore appearance: In response to enlarged pores caused by oil blockage, oil control and keratin regulation are used to help shrink the visual effect of pores.
