PCA SKIN Hyaluronic Acid Boosting Face Serum 1 oz Pump — Niacinamide & Ceramides for 24‑Hour Hydration

PCA SKIN Hyaluronic Acid Boosting Face Serum is a lightweight, multi-level hydration serum that helps replenish moisture, supports natural hyaluronic acid production, and smooths the appearance of fine lines.

This serum combines targeted humectants with barrier-supporting lipids and tone-enhancing niacinamide to strengthen skin hydration from surface to deeper layers. Formulated without synthetic dyes or fragrance and packaged in a convenient 1 oz pump, it layers easily under moisturizers and makeup to reinforce moisture retention and improve texture over time.

How does this serum hydrate at different skin depths?

The formula works on three hydration levels: immediate surface moisture, deeper delivery with low molecular weight hyaluronic fragments, and stimulation of the skin’s own hyaluronic acid production. That combination helps skin feel plumper and appear smoother without a heavy finish.

• Surface humectants draw and hold moisture on the outer skin.
• Hydrolyzed hyaluronic acid penetrates to hydrate deeper layers.
• HA-boosting complex supports the skin’s native HA synthesis for longer-lasting effects.

Will this help reduce the look of fine lines and uneven tone?

Regular use improves hydration and skin elasticity, which can make fine lines less noticeable and give a more even, refreshed look. Niacinamide contributes to a balanced tone while ceramides reinforce the skin barrier to help prevent moisture loss that can accentuate wrinkles.

• Niacinamide helps calm and even skin tone.
• Ceramides restore barrier function and lock in hydration.
• Consistent moisturization supports a smoother surface appearance.

How do I incorporate this serum into my daily routine?

Apply a small pump to clean, damp skin on face and neck morning and night for best results. Follow with a moisturizer and sunscreen in the morning; at night you can layer oils or richer creams if desired. Its lightweight texture makes it compatible with most serums and treatments.

• Use after cleansing and any water-based treatments.
• Press gently into damp skin to help absorption.
• Seal with moisturizer or sunscreen depending on time of day.

Is this serum suitable for sensitive or combination skin?

The formulation is designed to be lightweight and non-greasy, suited to dry, normal, combination, oily, and many sensitive skin types. It omits synthetic dyes and fragrances to reduce irritation risk; however, patch testing is recommended if you have highly reactive skin.

• Free from added fragrance and synthetic colorants.
• Light cream texture absorbs quickly without residue.
• Appropriate as a layering step under other treatments.

Who is this for: This serum is for anyone seeking deeper, longer-lasting hydration and improved skin texture—especially those noticing dehydration lines, uneven tone, or a weakened moisture barrier. It fits into minimalist and multi-step routines alike and is a good choice for users who want a hydrating booster that partners well with other PCA SKIN or personal skincare products.
