Cos De BAHA Arbutin Niacinamide Serum (AN) 30ml30ml

Key Ingredients

• Alpha-Arbutin -- brightening active that helps target the look of dark spots and uneven tone
• Niacinamide -- brightening and skin-barrier-supporting active
• Hyaluronic Acid -- humectant for hydration
• Panthenol -- soothing, moisturizing active (pro-Vitamin B5)
• A trailing blend of botanical extracts appears near the end of the ingredient list, but the exact composition of this blend differs between the two independent sources MedEasy cross-checked (incidecoder.com and masksheets.com) -- see sourcing note

Key Features

• Serum built around Alpha-Arbutin and Niacinamide, marketed under the "AN" designation in the Cos De BAHA lineup for brightening
• 30ml dropper-bottle format intended for regular use as a targeted brightening step
• Contains Hyaluronic Acid and Panthenol for added hydration alongside the brightening actives

Benefits

• Alpha-Arbutin and Niacinamide are both commonly used in skincare to help support a more even-looking skin tone with consistent use
• Hyaluronic Acid and Panthenol help support hydration and soothe the skin alongside the brightening actives
• Lightweight serum texture designed to layer easily under moisturizer

Who Can Use This Product

• Adults looking to add a brightening serum focused on Arbutin and Niacinamide to their skincare routine
• Not recommended for anyone with a known sensitivity to Arbutin or Niacinamide without first patch-testing
• Pregnant or breastfeeding individuals and anyone with a diagnosed skin condition should consult a doctor before use
• Buyers should take care to purchase this specific "AN" (Arbutin Niacinamide) serum and not confuse it with a visually similar Cos De BAHA product that contains Hydroquinone, a different and more potent brightening ingredient with its own separate usage precautions

How to Use

• Apply to cleansed skin, using a few drops and gently patting/massaging into the face and neck
• Follow with moisturizer and, in the daytime, a broad-spectrum sunscreen, as brightening actives are often paired with sun protection
• Patch-test on a small area of skin before first full-face use

Storage & Safety

• Store in a cool, dry place away from direct sunlight
• Keep the dropper/cap tightly closed after use
• Discontinue use and consult a doctor if irritation, redness, or a burning sensation occurs
• Keep out of reach of children
• Sourcing note: MedEasy cross-checked this product's ingredient list across two independent ingredient databases (incidecoder.com and masksheets.com). Both agree on the headline actives -- Alpha-Arbutin, Niacinamide, Hyaluronic Acid, and Panthenol -- but they show a genuine conflict in the trailing botanical-extract blend listed near the end of the full ingredient panel, with the two sources naming different additional plant extracts in that section. MedEasy could not resolve which trailing list is accurate and is disclosing both sources' disagreement rather than presenting either as definitive. Separately, buyers should note that Cos De BAHA also sells a visually similar product in its "AN" lineup that contains Hydroquinone -- a distinct, separate SKU from this Arbutin Niacinamide serum -- and care should be taken not to confuse the two when purchasing.

FAQ (Frequently Asked Questions)

Q: What are the main active ingredients in this serum?

A: Alpha-Arbutin and Niacinamide are the headline brightening actives, alongside Hyaluronic Acid and Panthenol for hydration.

Q: Is the full ingredient list confirmed?

A: The headline actives are confirmed by two independent sources, but the trailing botanical-extract blend differs between those two sources, so that portion of the list could not be fully confirmed.

Q: Does this product contain Hydroquinone?

A: No, this specific Arbutin Niacinamide (AN) serum does not list Hydroquinone as an ingredient. A different, visually similar Cos De BAHA product does contain Hydroquinone, so please check the product name carefully when purchasing.

Q: Do I need sunscreen if I use this serum?

A: Yes. Brightening actives like Arbutin and Niacinamide are generally recommended alongside daytime sunscreen use as part of a complete skincare routine.

Q: Is this suitable for sensitive skin?

A: Patch-test first, as Arbutin and Niacinamide can be irritating for some sensitive skin types.
