Cos De BAHA Niacinamide 5% + Arbutin 5% Serum (AN) 30ml

Cos De BAHA Niacinamide 5% + Arbutin 5% Serum (AN) 30ml is a Korean brightening serum that combines two well-researched ingredients to help address hyperpigmentation and uneven skin tone. This lightweight formula sits in the serum category, delivering targeted treatment through niacinamide's barrier-supporting properties and arbutin's gentle brightening action. It works particularly well for skin dealing with stubborn dark spots, post-acne marks, or general dullness that tends to worsen during Bangladesh's long monsoon season when UV exposure remains high despite cloud cover.

What is Cos De BAHA Niacinamide 5% + Arbutin 5% Serum (AN) 30ml and how it works

Cos De BAHA Niacinamide 5% + Arbutin 5% Serum (AN) 30ml is a Korean brightening treatment that uses niacinamide and arbutin to help reduce the appearance of dark spots and even skin tone. Niacinamide, a form of vitamin B3, supports the skin barrier while helping regulate melanin production. Arbutin, derived from bearberry plant extract, works to inhibit tyrosinase enzyme activity, which may help fade existing pigmentation over time. Together, they create a balanced approach to addressing hyperpigmentation without the harshness often found in stronger brightening agents.

Who benefits most

• Skin with post-acne marks that linger longer than expected
• Uneven skin tone from sun exposure or hormonal changes
• Mild to moderate hyperpigmentation on face or body areas
• Sensitive skin that reacts to harsher brightening ingredients
• Dehydrated skin needing barrier support alongside treatment
• Combination skin that prefers lightweight, non-greasy textures

Cos De BAHA Niacinamide 5% + Arbutin 5% Serum (AN) 30ml suits most skin types, though those with very dry skin may want to layer a richer moisturizer over it in winter months.

How to apply Cos De BAHA Niacinamide 5% + Arbutin 5% Serum (AN) 30ml

1. Use 2-3 drops of Cos De BAHA Niacinamide 5% + Arbutin 5% Serum (AN) 30ml on clean, dry skin after cleansing
2. Apply morning and evening, pressing gently into face and neck — avoid the delicate eye area
3. Allow 1-2 minutes for absorption before following with moisturizer
4. Always finish with broad-spectrum sunscreen in the morning — this is essential for any brightening routine in Bangladesh's strong UV environment
5. For best results, use consistently for at least 6-8 weeks alongside other gentle skincare products

What to expect over time

Results from Cos De BAHA Niacinamide 5% + Arbutin 5% Serum (AN) 30ml develop gradually with consistent use. Most people notice subtle improvements in skin brightness within 2-3 weeks, while significant fading of dark spots typically takes 6-12 weeks. The serum absorbs quickly without leaving residue, making it practical for Bangladesh's humid climate where heavy products can feel uncomfortable. Remember that no serum delivers instant results — lasting change comes from patience, sun protection, and incorporating the product into a regular routine rather than expecting overnight transformation.
