Brightening Serum Refill Brighten & Hydrate

The Byoma Brightening Serum Refill is a restock, not a new bottle-and-dropper set: pop your existing dropper onto this one and keep going. The formula pairs niacinamide with hyaluronic acid to work on uneven tone and dullness, with the Tri-Ceramide Complex underneath holding the barrier steady.

What it actually does

• Works on tone, not just glow. Niacinamide is the brightening ingredient here, aimed at evening out patchiness rather than simply adding shine.
• Eases pigmentation over time. Byoma describes the serum as helping soften the look of hyperpigmentation and uneven tone, with daily use building the effect.
• Hydrates while it brightens. Hyaluronic acid keeps the skin plump, so the formula isn't drying the way some tone-correcting serums can be.
• Supports the barrier. Ceramides, cholesterol and fatty acids in the Tri-Ceramide Complex strengthen barrier function, which the brand also links to antioxidant defence against daily environmental stress.
• Lower-waste packaging. Dropper reused, recyclable bottle, no second pipette in landfill.

How to use

1. Transfer the dropper from your finished bottle to the refill.
2. Apply a few drops to clean skin before moisturiser, morning or evening.
3. Pat, don't drag. Include the areas where tone is most uneven.
4. Always finish daytime use with SPF. Sun exposure undoes brightening work faster than any serum can build it.

Questions

Why doesn't it include a dropper?

Because the whole system is built around keeping one dropper for many bottles. If you don't have one yet, start with the standard version.

How soon will I notice anything?

Byoma says the serum visibly brightens from first use and that tone and radiance keep improving with daily application. Pigmentation is slower to shift than surface brightness, so judge it over weeks rather than days.

Can I use it with the hydrating serum?

Yes — both are lightweight. Apply whichever is thinner first and let it settle before the next layer, or alternate them between morning and night.

How long does delivery take?

Delivery takes 3 to 21 working days, depending on availability. We confirm stock first and let you know if anything changes.

How can I pay?

Credit card, debit card, Instapay and mobile wallets — there is no cash on delivery.

Can I return it?

Only if it's defective, damaged or expired, and reported within 1 day of delivery. Verified returns are refunded to the original payment method within 15 to 30 days.
