Skin Barrier Solution Microbiome Serum 50ml

A microbiome-focused wrinkle care serum that supports the skin barrier

This wrinkle-improving functional serum is built around bifida ferment lysate as its hero ingredient. The formula includes a blend of fermented probiotics—lactococcus, lactobacillus, and more—plus lactobacillus extracellular vesicles, all designed with your skin's microbiome balance in mind. Dispense a few drops with the dropper, smooth it over your face, and feel it absorb lightly while refining your skin's texture.

Core actives for barrier strength and deep hydration

The formula brings together a well-rounded lineup of barrier-supporting ingredients.

• Bifida Ferment Lysate: helps maintain healthy skin condition
• Ceramide NP: reinforces the skin barrier
• Sodium Hyaluronate: delivers and locks in hydration
• Adenosine: a functional ingredient for wrinkle improvement

Brewers yeast extract and alpha-glucan oligosaccharide support the skin's natural balance, while olive oil adds a nourishing touch.

For skin concerned with loss of firmness and dryness

This serum is a great match if you've noticed your skin isn't as firm as it used to be, or if a weakened barrier leaves you feeling dry more easily. As a wrinkle-improving functional cosmetic approved by the Ministry of Food and Drug Safety, consistent use can help visibly improve skin texture. We recommend it for anyone looking to address both barrier care and wrinkle concerns in one serum step.

Microbiome Serum, Right After Toner

Serum is the step that comes right after you've prepped your skin with toner. This formula features Bifida Ferment Lysate and Lactobacillus Ferment, making it a skin barrier-focused treatment best used during your essence or ampoule step. Follow with a cream to seal in all the active ingredients.

Morning and Evening Use

There are no photosensitive ingredients, so you can use it both morning and night. In the morning, it delivers hydration and barrier protection. In the evening, it helps restore skin after a long day.

2–3 Drops with the Dropper, Gently Pressed In

Dispense 2–3 drops onto your palm using the dropper. Dot the serum onto both cheeks, forehead, nose, and chin, then gently spread from the center of your face outward. Finish by pressing your palms over your entire face to help the serum absorb more fully.

Routine Pairings by Skin Concern

• Dry, tight skin: Layer with a ceramide cream to amplify barrier-strengthening benefits
• Sensitized, reactive skin: Keep it simple—use this serum alone after a gentle toner
• Fine lines: This is a wrinkle-care functional product, so use it consistently and pair with an eye cream for best results

Storage and Usage Notes

Store in a cool place away from direct sunlight. After each use, wipe the dropper clean to prevent product buildup. If you experience redness, swelling, itching, or other reactions during use, discontinue immediately and consult a dermatologist.
