[haruharu wonder] black rice night knight retinol serum 20ml.

The Science of “Low Irritant” Retinoid Tech
The Black Rice Night Knight Serum solves the “Retinol Fear” problem. Many users avoid Vitamin A due to redness and peeling. Haruharu addresses this through their patented U.D.T. (Ultra Deep Technology), which encapsulates the active ingredients in liposomes derived from Ginseng.

0.1% Pure Retinol: This specific concentration is the “sweet spot” for efficacy—it is strong enough to trigger collagen production but gentle enough for daily use on sensitive skin.

Fermented Black Rice: Provides a dense concentration of anthocyanins (antioxidants) that protect the skin cells while they undergo the intensive renewal process triggered by the retinol.

Key Ingredients & Benefits:

Pure Retinol (0.1%): The gold standard for anti aging; it minimizes the appearance of pores, smooths uneven texture, and reduces fine lines.

Black Rice Extract: Fermented to increase potency, it provides deep hydration and calms the skin during the Vitamin A activity.

Adenosine: A functional anti wrinkle ingredient that energizes the skin’s surface to look smoother and more resilient.

Soybean Oil: Acts as a natural carrier that stabilizes the retinol and prevents the “tight” feeling often associated with renewal serums.

Coptis Japonica Root Extract: A traditional medicinal herb used to lower skin temperature and soothe inflammation.

Why Your Customers Will Love It:

The “Wake Up Glow”: It works overnight to slough off dead skin cells, so you wake up with noticeably softer, more “polished” skin.

Texture Refinement: It is particularly effective at clearing up “texture bumps” and making enlarged pores appear smaller and tighter.

Airless Pump Packaging: Retinol is highly sensitive to light and air. This serum comes in an opaque airless pump to ensure the last drop is just as potent as the first.

Clean & Vegan: Fragrance free, cruelty free, and formulated with 95% naturally derived ingredients.

How to Use:

Prep: Use only in your Nighttime (PM) routine. Cleanse and tone the skin first.

Apply: Dispense 1–2 pumps and apply a thin layer over the entire face, avoiding the immediate eye and lip area.

Seal: Follow with a rich moisturizer like the SoonJung 2x Barrier Intensive Cream to “sandwich” the hydration.

The “Slow Start” Rule: If you are new to retinol, use it 2–3 times a week for the first 14 days, then increase frequency as your skin adjusts.

Pro Tip: Always wear SPF 50+ the next morning. Retinol makes your skin more sensitive to UV rays; skipping sunscreen can lead to sun damage.
