GOODAL Vitamin C Brightening Serum 30ml + 30ml Refill — Green Tangerine, 5% Niacinamide & Exosome Delivery for Dark Spots

GOODAL Vitamin C Dark Spot Brightening Serum is a daily lightweight gel serum (30ml bottle + 30ml refill) designed to reduce dark spots and even skin tone using green tangerine antioxidants, 5% niacinamide, and exosome delivery technology.

This two-piece package includes a full-size 30ml bottle plus a 30ml refill pouch, giving you a total of 60ml of brightening care. The formula blends a stabilized, low-irritation vitamin C complex with antioxidant-rich green tangerine extract and 5% niacinamide. Advanced exosome technology helps shuttle active ingredients deeper into the skin, while the gel texture absorbs quickly and leaves a fresh, non-sticky finish suitable for daily use.

How quickly will I notice reduced dark spots and uneven tone?

Clinical results reported visible improvements in spot appearance and skin radiance within seven days for many users, with continued improvement over regular use. Individual results vary based on skin type, existing pigmentation, and consistency of application.

• Clinically observed improvements in spot visibility in approximately 7 days.
• Regular daily application enhances cumulative brightening effects.
• Works on post-acne marks, sun spots, and general uneven tone.

Will this serum be gentle enough for sensitive skin?

The serum uses a low-irritation vitamin C complex and a lightweight gel base that minimizes tackiness and reduces the chance of surface irritation. Combining vitamin C with 5% niacinamide helps soothe and support the skin barrier while delivering brightening benefits.

• Stabilized vitamin C formulation designed to be less irritating than raw ascorbic acid.
• 5% niacinamide to calm redness and improve barrier function.
• Fast-absorbing gel minimizes residue and reduces layering friction under moisturizers.

What makes the formula more effective than standard vitamin C serums?

This product pairs antioxidant-rich green tangerine extract with exosome technology to improve ingredient delivery and 5% niacinamide to target discoloration and texture. The synergy of antioxidants, delivery technology, and a moderate niacinamide concentration aims to produce brighter, more even skin with consistent use.

• Green tangerine provides a source of antioxidants that help protect and brighten skin.
• Exosome tech enhances penetration, helping active ingredients reach deeper layers.
• Niacinamide supports pigment reduction and overall tone improvement.

How should I incorporate this serum into my routine?

Use the serum after cleansing and toning, applying a few drops to the face and neck once or twice daily depending on tolerance. Follow with a moisturizer and daytime SPF to protect the new brighter-looking skin from UV-induced pigmentation.

• Apply to clean, dry skin morning and/or evening as tolerated.
• Layer under moisturizer; use sunscreen during the day.
• Refill pouch allows easy replacement without discarding the main bottle.
