A classic repair mask from Rejuran, a top Korean medical beauty brand
The main positioning of the Black Box is “powerful repair” and “barrier strengthening,” placing greater emphasis on caring for damaged skin compared to other models from the same brand.

1. Core ingredient: c-PDRN (patented salmon DNA)
   This is the soul ingredient of Rejuran. DNA fragments extracted from salmon are extremely similar to human DNA.
   Benefits: Penetrates deep into the skin, promotes cell regeneration, accelerates wound healing, reverses skin aging, and improves overall skin condition.
2. Pantheno Vitamin B5
   The black box is specially enriched with a high concentration of panthenol. Benefits: This is a recognized barrier-repairing ingredient, strengthening the skin’s defenses, soothing redness, swelling, dryness, and itching, and providing deep hydration.
3. Patented mask paper (microfiber)
   Made from ultra-fine microfiber material, it feels as soft as silk. It perfectly conforms to facial contours and carries a large amount of serum, delivering active ingredients into the deep layers of the skin.
   The “Black Box” is the most restorative in the entire series and is especially suitable for:

1. Post-cosmetic care: After laser or hydrating injections, if your skin is fragile and needs quick repair (but consult a doctor before the wound has healed).

2. Damaged Barrier Skin: Skin prone to redness, irritation, and seasonal allergies.

3. Acne-Prone / Imperfect Skin: Helps reduce redness, swelling, acne marks, and stabilize skin condition.

4. Acid Tolerance Period: Emergency treatment when retinol or acidic products cause peeling or sensitivity.
