Arencia Retinal Booster Shot is a rejuvenating night serum designed to smooth texture, refine pores, and support firmer-looking skin. Powered by retinal, caffeine, and ectoin, it energizes tired skin, minimizes visible fatigue, and protects against environmental stressors. Skin-barrier lipids and peptides provide hydration and resilience for a refreshed, even complexion. Ideal for rough or textured skin, this serum helps promote smoother, more radiant skin over time. Apply a thin layer at night on clean skin and allow it to absorb before moisturizing.
