In the treatment of hyperpigmentation, Hydroquinone has long been considered the "gold standard" active ingredient, recognized by dermatologists worldwide for its powerful brightening effects and rapid melanin inhibition.
Thanks to this, Hydroquinone remains an important choice in a doctor's treatment protocol, especially for severe hyperpigmentation or deep melasma.
At the same time, with the development of dermatological science, more and more new active ingredients are being researched to diversify options for the skin, providing more sustainable pigmentation improvement, suitable for daily care needs. And Niacinamide is one of the typical representatives of this direction.

Hydroquinone – A classic active ingredient that maintains its "gold standard" position

Hydroquinone works by inhibiting the tyrosinase enzyme, reducing the synthesis of melanin – the pigment that determines skin color. Thanks to this direct effect, results are often seen very quickly: dark spots and melasma can significantly fade after just a few weeks of use according to professional guidance.

However, due to its strong inhibitory mechanism, Hydroquinone is often recommended for short-term regimens under the supervision of dermatologists, rather than for continuous use in daily skincare.

Therefore, experts are constantly looking for gentler alternative or complementary active ingredients that can accompany the skin long-term while maintaining effectiveness.

Niacinamide 23% – A new direction in pigmentation regulation and skin recovery

Niacinamide (Vitamin B3) is already familiar in dermatology due to its multi-mechanism regulatory capabilities: it inhibits melanin transport, reduces inflammation, increases ceramide synthesis, and strengthens the skin barrier.
At a concentration of 23%, this active ingredient not only acts as a skin brightener, but also has the ability to deeply affect many biological processes of the skin, helping to:

• Improve even skin tone, reduce dark spots and post-inflammatory hyperpigmentation.
• Support the restoration of the epidermal barrier, moisturize and balance the skin.
• Reduce acne inflammation, oiliness, and enlarged pores.

Importantly, Niacinamide works by regulating and restoring, without excessively interfering with the skin's natural processes, making it suitable for long-term use, alongside specialized treatment regimens.

When technology elevates Niacinamide to a new level

Not all products containing Niacinamide achieve maximum effectiveness at high concentrations, as this active ingredient can easily cause stinging if not properly stabilized.
Based on in-depth research into skin mechanisms and tolerance, oh!oh!

From treatment to care: When skin brightening is a journey of recovery

If Hydroquinone represents "powerful treatment," then Niacinamide 23% opens up a "smart care" approach that helps the skin maintain healthy radiance sustainably through each regeneration cycle.
These two approaches are not mutually exclusive, but complement each other in a comprehensive skincare regimen: treatment – recovery – maintenance.
With oh!oh! Daily Nia23 Advanced Correcting Serum, caring for hyperpigmented skin is no longer a series of short-term regimens, but becomes a scientific, gentler, and more sustainable journey every day.
In the modern skincare world, there is no "one-size-fits-all" formula. Hydroquinone remains a valuable medicinal ingredient, but Niacinamide 23% opens a new chapter where users have a safer, more sustainable, and more skin-friendly option for sensitive skin or long-term use.
