Benefits:

Brightening & evening skin tone Alpha-arbutin inhibits melanin formation, helping fade dark spots, hyperpigmentation, and even out dullness. 

Hydration & skin softness Rice bran water is rich in amino acids and minerals, helps moisturize, nourish, give a plump / dewy effect. 

Gentle / suitable for many skin types Because of its mild formula, many sensitive / combination skins can tolerate it. 

Improved texture & glow Over time, skin tends to look more luminous, smoother texture, with “radiant / glass-skin” effect according to reviews.

How to Use:

To get the best results with minimal irritation, here’s how to integrate it into your routine:

1. Cleanse your face properly. Remove makeup / sunscreen / impurities first

2. Use a toner (especially a hydrating one) if that’s part of your routine — this helps prep the skin. 

3. Apply the serum

Use 2-3 drops and place them on your fingertips. 

Gently pat or massage into the skin until fully absorbed. 

4. Follow up with moisturizer to seal in hydration. 

5. Sun protection (SPF) is very important, especially in the morning, because brightening ingredients (like arbutin) make skin more vulnerable to UV which can reverse the brightening effect or cause new pigmentation

When to Use / Frequency:

you can use it morning and night. 

However, if your skin is sensitive or new to brighteners, it might be better to start with once daily (or even every other night) to see how your skin tolerates it.

Always monitor for irritation (redness / stinging / peeling) and reduce frequency if needed.

Precautions

Patch-test first, especially if you have sensitive skin.

Avoid contact with eyes.

If using other strong active ingredients (like high percentages of acids, strong retinoids, etc.), be careful of irritation. Sometimes layering many actives can be harsh.

If you notice irritation, scaling, or excessive peeling, pause use until skin recovers.
