ARENCIA Vitamin C Booster Serum 30ml — Glutathione & Niacinamide for Brightening and Glass Skin

ARENCIA Vitamin C Booster Shot Serum is a lightweight 30ml Korean-style brightening and antioxidant serum that combines stable vitamin C with glutathione, niacinamide and vitamin E to target dark spots, refine texture and support a glowing glass-skin finish.

This concentrated booster is formulated for daily or targeted use to refresh dull skin, help reduce the appearance of uneven tone and deliver antioxidant support. The fast-absorbing texture layers well under moisturizers and sunscreen and is built around a stable vitamin C complex that pairs with niacinamide for barrier comfort and glutathione plus vitamin E for environmental defense. Designed for skin texture refinement and a luminous finish, the serum arrives in a 30ml (1.01 fl. oz.) vial for easy morning or evening application.

How does this serum help reduce dark spots and uneven tone?

The formula combines stable vitamin C with glutathione and niacinamide to address the look of discoloration and promote a more uniform complexion. Regular use can help the skin appear brighter and more even while supporting overall radiance.

• Stable vitamin C complex to help refine skin tone and texture.
• Glutathione for antioxidant support that complements brightening action.
• Niacinamide to soothe and maintain a healthy-looking barrier.
• Lightweight delivery for targeted application on spots or overall skin.

Is the serum suitable for sensitive or combination skin types?

ARENCIA’s booster is formulated with niacinamide to promote comfort and support the skin’s natural barrier, and the texture is designed to absorb quickly without stickiness. Those with sensitive skin should patch-test and introduce the product gradually, especially if using other active ingredients.

• Niacinamide helps reduce irritation risk and supports barrier function.
• Fast-absorbing, non-greasy texture layers under moisturizer and sunscreen.
• Suitable for targeted spot treatment as well as all-over use.
• Patch testing recommended for reactive skin or concurrent actives.

How do I incorporate the booster into my routine for best results?

Use the serum once or twice daily depending on tolerance and other actives in your regimen. Apply a few drops to clean skin, press gently over areas with dark spots or fine lines, and follow with moisturizer and SPF in the morning.

• Morning: apply after cleansing, then sunscreen to protect brightened areas.
• Evening: layer before richer creams for overnight renewal.
• Use as a booster on specific zones or across the face for all-over glow.
• Avoid mixing with very strong exfoliating acids at first; introduce slowly.

What performance and sensory benefits can I expect?

The serum focuses on texture refinement and a luminous finish while remaining lightweight and quick to absorb. Antioxidant ingredients help defend against everyday stressors that can dull the complexion, and the formula is crafted to sit comfortably beneath other skincare products.

• Light, fast-absorbing texture with no sticky residue.
• Targets dullness, fine lines and signs of uneven tone.
• Antioxidant blend (glutathione, vitamin E) supports skin resilience.
• Compatible with layering under moisturizers and sunscreen.

Who is this for? ARENCIA Vitamin C Booster Shot is aimed at anyone seeking a compact, high-potency brightening step—ideal for people with visible dark spots, dull or uneven tone, and those building a Korean-inspired "glass skin" routine. It suits morning or evening use, works well when layered under hydrating products and is a practical addition for both targeted spot care and daily brightening maintenance. If you have very reactive skin, introduce it gradually and consult a skincare professional for personalized guidance.
