Beauty of Joseon Glow Deep Serum - Rice+Alpha-Arbutin 30ml

Alpha-Arbutin is a derivative of hydroquinone, known for its skin-brightening properties. It works by inhibiting tyrosinase, an enzyme crucial for melanin production, thereby reducing the appearance of dark spots, hyperpigmentation, and evening out skin tone without the harshness often associated with hydroquinone.

Apply 2-3 drops of the serum after cleansing and toning your skin. Gently pat it onto your face for absorption. Follow with your preferred moisturizer. It can be used both in the morning and evening.

Yes, this serum is generally formulated for daily use, both morning and evening. For sensitive skin, we recommend performing a patch test on a small area of your skin before full facial application to ensure compatibility. If irritation occurs, discontinue use.

Results can vary depending on individual skin concerns and consistency of use. Typically, visible improvements in brightness and the reduction of dark spots can be observed within 4-8 weeks of consistent daily application.

This serum is generally well-tolerated. However, when combining with other potent actives like Vitamin C or Retinol, it's advisable to introduce them gradually. Consider alternating use (e.g., Vitamin C in the morning, this serum at night) or using them on different days to avoid potential irritation. Always observe your skin's reaction.

> Info needed: Specific shelf life and PAO (Period After Opening) details. Generally, unopened serums maintain efficacy for 2-3 years, and once opened, they are best used within 6 to 12 months for optimal performance.

Ensure consistent daily application for at least 4-6 weeks, as skin cell turnover and hyperpigmentation improvement take time. Also, consistently use a broad-spectrum SPF daily, as sun exposure can undo brightening efforts.

This can sometimes occur when introducing new active ingredients like Alpha-Arbutin. Start by using the serum every other day, then gradually increase frequency. Perform a patch test on a small, inconspicuous area before full facial application. If irritation persists, discontinue use and consult a dermatologist.

Ensure the dropper is clean and not clogged. If the product appears slightly cloudy or separates, gently shake the bottle before use. Store at room temperature to maintain product consistency.

Apply a smaller amount (2-3 drops) and allow it to absorb fully before applying subsequent products. Over-application can sometimes lead to a sticky residue. Gently patting the serum into the skin can also aid absorption.
