Medicube RETINOL NMN BOOSTING SERUM 30ml

When skin starts to look tired, texture feels uneven, pores appear more noticeable, and fine lines show up faster, you need something that works beyond “instant hydration.” This serum combines a retinoid duo (retinol + retinal) to support renewal and smoother-looking skin, plus peptides to help improve the appearance of firmness and elasticity. Barrier-supporting ingredients are included to keep the skin feeling more comfortable while using retinoids.

What it helps improve (visibly)

• Skin texture: promotes a smoother, more even look and feel.

• Pores: won’t erase pores, but can help make them look less noticeable by refining the overall texture.

• Fine lines: supports a smoother appearance, especially for dehydration-related lines.

• Tone & radiance: helps improve the look of dullness and uneven tone, including post-acne marks.

• Overall look: with consistent use, skin can appear firmer and more “refreshed.”

Smart formula (more than just retinol)

• Retinol (1,140 ppm) + Retinal: a retinoid duo to support renewal, smoother texture, and improved appearance of lines and pores.

• 4 Peptides: help promote a firmer, more resilient-looking complexion.

• NMN (100 ppm): often used to support skin vitality and barrier function.

• Two forms of Vitamin C: help support a brighter, more even-looking tone.

• Ferments + Beta-glucan: comfort and support while introducing retinoids.

• Centella complex: soothing support to reduce the feeling of discomfort.

• Ceramide NP + Squalane + Panthenol + Allantoin: barrier care, hydration, and reduced dryness.

How to use (for comfort)

Use at night on clean, dry skin. Apply a small amount (about a pea-size for the full face), then follow with a moisturizer.

For sensitive skin: try the “sandwich” method
moisturizer → serum → moisturizer.

How to introduce it (safest approach)

• Week 1: 2 nights

• Week 2: 3 nights

• From week 3: increase gradually only if your skin feels comfortable

If dryness, redness, or flaking becomes too noticeable, reduce frequency and focus on barrier repair.

Avoid in the same night routine

• Strong exfoliants (AHA/BHA), peels, scrubs

• High-strength vitamin C (better in a separate AM routine)

• Layering too many strong actives at once

Golden rule

Daily SPF50+ is essential while using retinoids.

Best for

• Uneven texture and visible pores

• Early signs of aging (fine lines, loss of firmness)

• Dullness, uneven tone, post-acne marks

• Anyone who wants retinoids with a comfort-focused formula (with gradual introduction)
