## Description

Cos-IQ 5% Niacinamide Face Serum for Clear, Glowing Skin, 30ml | beginner-friendly strength, fades marks, minimizes pores, oil control, non-comedogenic, all skin types : desertcart.in: Beauty

Review: Worthy - The CosIQ Vitamin B3 5% Serum is a lightweight, fast-absorbing serum designed to improve skin texture and tone. With 5% niacinamide (Vitamin B3), it helps reduce dark spots, minimize pores, and control oil production, making it great for oily and combination skin types. Users often report smoother, more even-toned skin with regular use. It's gentle enough for daily application and works well under other skincare products. However, results may vary for those with sensitive skin, and some users might need to introduce it gradually to avoid irritation. I am loving this product.100 percent recommended.
Review: 5% Niacinamide is slower but effective - Overall everthing is good about the product. It have simple & safe ingredients. Fragrance free. Subtle moisturizing so I skip mositurizer & apply sunscreen. Best for oily acne prone skin. Doesn't cause any irritation. It is good to start at the initial phase of acnes. It will prevent it from growing big & removes all acne marks. If there are already acnes like 1 month old then it takes 2 months to remove the acne marks. I don't see any improvement in 6 month old acne marks. It is good product in affordable range.
