About P Serum + Niacinamide (NIA)
P Serum + Niacinamide (NIA) is a personalized serum by Universkin where your RELUXE provider selects the exact niacinamide concentration based on your unique skin assessment. Niacinamide is one of the most versatile active ingredients in dermatology—it balances oil production, strengthens the skin barrier, reduces redness, minimizes pore appearance, and improves overall skin texture. Because Universkin allows custom concentrations, your serum is precisely calibrated to your skin's needs—not a one-size-fits-all formula. Available exclusively at RELUXE Med Spa in Westfield and Carmel, Indiana.
What makes Universkin fundamentally different from off-the-shelf skincare is the personalization. Your RELUXE provider analyzes your skin, identifies your specific concerns, and selects the active ingredients and concentrations that will address them most effectively. Niacinamide is the foundation of most Universkin blends because it plays well with nearly every other active—it can be combined with retinol for anti-aging, azelaic acid for redness, or tranexamic acid for pigmentation. The result is a serum that's designed specifically for your face, your concerns, and your goals.
