Medicube Retinol NMN Boosting Serum

• Normal, combination, oily and dry skin
• Sensitive skin: low-irritation formula with a soothing system
• Acne-prone skin: for smoothing the look of texture, pores, scars and fine lines

Target concerns

• Fine lines and wrinkles: especially crow’s feet, nasolabial folds and marionette lines
• Enlarged pores and uneven texture
• Dullness, loss of firmness
• Pigmentation, post-inflammatory marks and uneven tone

Beginners (around 2 weeks, depending on sensitivity):

• Night 1–2:
  Cleanse and dry skin thoroughly.
  Apply toner or a lightweight hydrator if desired.
  Use a small amount (½ to 1 pump) and smooth over the face, avoiding the eye area and mouth corners.
  Finish with a nourishing moisturiser.

Recommended frequency: 2 nights per week, always leaving rest days between applications.

After 1-2 weeks (if well tolerated):

• Increase to every other night, keeping use night-time only.
• If your skin is very used to retinol and shows no irritation, you can work up to near-daily use, as tolerated.

Rules of gold with retinol:

• Night use only. Retinol is sensitive to light and heat; during use, broad-spectrum SPF every morning is essential.
• Do not pair in the same routine with strong exfoliants, concentrated chemical peels or other retinoids to minimise unwanted reactions.
• If irritation shows up (strong stinging, heavy flaking, persistent redness): reduce frequency, or mix the serum with a soothing cream in your palm to cushion intensity.

Do not use during pregnancy or breastfeeding.

For external use only; patch testing is recommended. Stop use if irritation occurs.

Storage and precautions:

• Store in a cool place, 5–25°C (41–77°F).
• Keep away from direct sunlight and high temperatures.
• Avoid using alongside AHAs, BHAs, niacinamide and retinol in the same routine to minimise adverse reactions/allergies.
• If you use it in the morning, always finish with sunscreen.
• Use within 6 months of opening.

💡 FAQs: Using the Medicube Retinol NMN Boosting Serum

• 1. Is it normal to notice tingling, redness, or slight flaking at the beginning?Yes. Medicube indicates that retinol typically requires an adjustment period of up to 2 weeks, during which mild tingling, redness, or slight flaking may occur. It is also possible not to notice a visible reaction; this depends on your skin's sensitivity.
• 2. I don't feel anything after the first few applications. Can I use it on my entire face every night?The brand recommends not rushing: even if you don't feel a reaction initially, responses to retinol can appear later. Maintain a low frequency during the first few weeks and follow the staggered usage guide before increasing frequency.
• 3. What should I do if my skin gets irritated? If irritation occurs...
  Reduce the frequency (e.g., return to 1–2 nights per week).
  Mix the product with your moisturiser or a calming serum to reduce intensity.
  If irritation persists, discontinue use and consult a professional.
• 4. Can it be used long-term?According to Medicube, once the adaptation phase is complete and the skin remains comfortable, the serum is suitable for prolonged use as part of a consistent anti-aging routine.
• 5. Only at night, or during the day too?The brand itself recommends nighttime use. Although you may not apply it in the morning, retinol remains active in the skin, so daily use of sunscreen is mandatory while you are using the product.
