Frequently Asked Questions

Is the Tir Tir Niacinamide 20% Serum available in Bangladesh?

Yes, it is available at koreanbeautyhousebd.com with Cash on Delivery across Dhaka and all districts nationwide. Contact the team via Facebook or Instagram to confirm current stock before ordering.

What makes 20% Niacinamide different from regular Niacinamide serums?

Most serums use 2?5% Niacinamide, while this formula delivers 20% ? four to ten times the standard concentration ? for significantly faster and more visible results on pores, pigmentation, and oil control. It is one of the highest concentrations available in a Korean brightening serum.

What does Alpha Arbutin do for dark spots?

Alpha Arbutin blocks tyrosinase, the enzyme responsible for triggering melanin production in the skin, gradually lightening existing dark spots and preventing new discoloration from forming. Combined with Niacinamide and Glutathione, it delivers a multi-pathway brightening effect.

Is this serum safe for sensitive skin?

Yes, it is paraben-free, fragrance-free, and dermatologically tested, making it suitable for reactive and sensitive skin types with consistent use. If you have very reactive skin, patch test first and introduce it gradually ? once daily before moving to twice daily.

Can I use this serum with Retinol products already in my routine?

This serum already contains Retinol 500IU, so layering it with a separate high-strength Retinol product is not recommended, as it may increase the risk of irritation. Use this serum as your Retinol source and follow with a moisturizer and SPF in the morning.

Should I use this serum in the morning or at night?

It can be used both morning and evening ? apply after cleansing and toning, before moisturizer. In the morning, always follow with sunscreen, as Niacinamide and Retinol both increase the skin's sensitivity to UV exposure.

How long does delivery take in Bangladesh?

Dhaka orders arrive in 1 to 2 business days. All other districts are delivered within 3 to 5 business days, with COD available.

Key Ingredients of Tir Tir Niacinamide 20% Serum

Niacinamide (20%): A water-soluble form of Vitamin B3 that, at this high concentration, actively regulates sebaceous activity, reduces the visible size of enlarged pores, and gradually fades post-inflammatory hyperpigmentation left by acne and sun exposure. Consistent use also supports ceramide synthesis, strengthening the skin barrier and improving moisture retention over time.
Alpha Arbutin (2%): A stable, skin-safe brightening compound derived from the bearberry plant that inhibits tyrosinase ? the enzyme that triggers melanin formation ? to gradually fade dark spots and post-acne marks without causing irritation. At 2%, it works synergistically with Niacinamide and Glutathione to deliver faster, more uniform tone correction.
Glutathione: A naturally occurring antioxidant tripeptide found in skin cells that works by shifting melanin production from darker eumelanin toward lighter phaeomelanin, resulting in a progressively brighter and more even complexion. It also neutralizes oxidative stress caused by UV exposure and environmental pollutants that accelerate skin darkening.
Retinol (500IU): A Vitamin A derivative that accelerates skin cell turnover, stimulates collagen production in the deeper dermis, and reduces the visible appearance of fine lines and uneven texture over time. Its inclusion in this formula allows the serum to address both current pigmentation and early signs of aging in a single daily step.
Triple Hyaluronic Acid Complex (Hyaluronic Acid + Hydrolyzed Hyaluronic Acid + Sodium Hyaluronate): Three molecular weights of hyaluronic acid that penetrate the skin at different depths ? from the surface down to deeper layers ? delivering layered hydration that keeps skin plump, resilient, and comfortable throughout the day. This multi-depth approach ensures moisture is locked in at every level without a heavy or occlusive finish.
Zinc PCA: A compound that combines zinc's natural sebum-regulating and anti-inflammatory properties with PCA, a naturally occurring skin-hydrating amino acid derivative. It helps control excess oil production, calm surface-level irritation, and reduce the conditions that contribute to clogged pores and breakouts.

How to Use Tir Tir Niacinamide 20% Serum

Cleanse your face thoroughly and complete your toner step first.
Lightly shake the serum bottle before dispensing.
Apply a moderate amount ? 2 to 3 drops ? onto your fingertips.
Gently press and pat the serum across the face, following your skin's natural texture.
Allow it to absorb fully before applying moisturizer.
In your morning routine, always follow with a broad-spectrum sunscreen as the final step.
