Medicube Serums

The Medicube Red Serum 2.0 (30 ml) is the updated version of Medicube's flagship serum, using a barrier-focused formula with anti-inflammatory actives to reduce redness and support stressed skin. It works for skin that reacts easily or that has a compromised barrier from over-exfoliation or environmental stress. The 2.0 update improved the texture and active concentration compared to the original.

The Red Succinic Acid Serum (30 ml) takes a different approach within the same Red product family. Succinic acid is an alpha-hydroxy acid with mild exfoliating and brightening properties alongside antibacterial effects that benefit acne-prone skin. This serum suits people who want a barrier-supportive formula that also provides light exfoliation and pore-clearing benefits.

Medicube has built an entire sub-line of PDRN serums: the PDRN Pink Peptide Serum (30 ml), PDRN Pink Glutathione Serum Mist (100 ml), PDRN Pink Collagen Glow Jelly Mist Serum, and PDRN Pink Collagen Exosome Shot Serum 2000 (30 ml). Each combines PDRN - a salmon-derived polynucleotide with regenerative properties - with a different secondary active.

The Peptide version adds a lifting and firming angle; the Glutathione version targets oxidative stress and brightening; the Collagen Glow Jelly Mist is a spray-format serum for midday refreshing; and the Exosome Shot 2000 is the most concentrated option, layering PDRN with exosomes for intensive skin regeneration. For a first PDRN serum, the Peptide Serum is the most straightforward entry point in the line.

The Zero Pore Serum 2.0 (37 ml) targets enlarged pores, excess sebum, and rough skin texture. The formula uses pore-clearing actives to reduce the visible size of pores over consistent use and control sebum production across the T-zone. Like the Zero Pore Cream 2.0, this serum is built for oily and combination skin and should not be used as a replacement for a hydrating serum on dry skin.

For people building a pore-focused Medicube routine, the Zero Pore Serum 2.0 works as the active serum layer, with the Zero Pore One Day Cream or Hyaluronic Ceramide Jelly Cream as the moisturizing layer to prevent over-drying.

Medicube's brightening serums include the Kojic Acid Turmeric Niacinamide Serum (30 ml) and the Kojic Acid Turmeric Vita Jelly Mist Serum. The liquid serum version combines three well-studied brightening actives - kojic acid, turmeric extract, and niacinamide - targeting post-inflammatory hyperpigmentation, dull skin tone, and early sun spots. The Vita Jelly Mist version delivers the same brightening approach in a mist format for flexible application.

Kojic acid specifically inhibits melanin production at the tyrosinase enzyme level, while niacinamide reduces melanin transfer to skin cells. The combination provides a stronger brightening effect than either active alone. These serums are appropriate for skin with existing hyperpigmentation, not as a preventative-only formula.

The Collagen Glow Bubble Serum (100 ml) uses a carbonated bubble texture activated on application. The CO2 bubbles create a brief oxygenating effect and help the collagen-supporting formula absorb more evenly. The larger 100 ml size makes it more economical for daily use compared to Medicube's smaller 30 ml serum bottles. The glow-focused formula suits skin that looks dull or gray rather than skin with active breakouts or barrier damage.

The bubble texture is distinctive among Medicube's lineup and makes this serum easy to identify as a separate formula with its own application experience. It works well in the morning when skin looks tired, and the absorbed finish sits cleanly under SPF.

Two products in this collection come in mist format: the PDRN Pink Glutathione Serum Mist (100 ml) and the Kojic Acid Turmeric Vita Jelly Mist Serum. Mist serums let you apply active ingredients over makeup or throughout the day without disturbing your existing skincare base. Both are designed to be used after your morning routine is set, adding another dose of active ingredients at midday or in the evening before bed.

The larger bottle sizes of the mist formats (100 ml) reflect that they are meant for more frequent, lighter application rather than single-use concentrated dosing. They work well for people who want to add brightening or regenerative actives at multiple points in the day without a full reapplication routine.

Medicube serums are intended for single-product use in each routine step rather than stacking multiple serums simultaneously. The typical sequence is: toner - serum - moisturizer, with the serum chosen to target your primary concern. If you want to address two concerns (pore texture and brightening, for example), rotate serums morning and evening rather than applying both at once.

Some exceptions apply: the Collagen Glow Bubble Serum or a Jelly Mist can be used as a second layer over a liquid serum because of their textures. Apply water-thin serums first, gel or jelly formats second, and cream-texture products last before the moisturizer. The PDRN Exosome Shot 2000 is concentrated enough that it should sit alone in its routine step rather than layered under another serum.

Oily and combination skin types fit best with Zero Pore Serum 2.0 (sebum control), Kojic Acid Turmeric Niacinamide Serum (brightening without heavy emollients), or Red Succinic Acid Serum (mild exfoliation and pore clearing). Dry and normal skin types get more benefit from PDRN Pink Peptide Serum, Red Serum 2.0, or PDRN Pink Collagen Exosome Shot for barrier support and regeneration. Sensitive or post-treatment skin suits Red Serum 2.0 or PDRN Pink Glutathione for gentle regeneration without irritating actives.

Mature skin with firmness or density concerns benefits most from the PDRN Pink line, particularly the Peptide Serum and Collagen Exosome Shot 2000. These combine PDRN's regenerative signaling with peptides and exosomes that directly support collagen and elastin pathways.
