The Retinol Collagen Air Bubble Serum is an advanced anti-aging treatment powered by VT's exclusive AIR INJECTION™ and MICRO BUBBLATION™ technology, which creates ultra-fine 50μm microbubbles that burst on contact to deliver pure Retinol and low-molecular 300Da Collagen deep into the skin. Designed for daily use, it effectively targets reduced elasticity to minimize enlarged pores, smooth fine lines, and restore a visibly firmer, youthful glow. To ensure a gentle yet powerful performance, the clean formula is free of parabens and silicones, combining soothing Panthenol and moisture-rich Collareal Water to reinforce the skin barrier and prevent irritation, making it perfectly suitable for all skin types, including sensitive skin

Getting started
Patch test first — dab a little on your inner forearm or behind the ear and leave it a day before using it on your face. Introduce one new product at a time, a week or two apart, so you can tell what your skin is responding to. If anything stings, itches, or turns red, stop using it.
Where it goes in your routine
K-beauty layers thin to thick: cleanser → toner → essence, serum, or ampoule → moisturizer, and sunscreen last every morning. Let each layer settle for a moment before the next one — no need to wait for it to dry completely.
New to this? Our 4-product starter routine walks through the whole thing.
What not to layer at once
Exfoliating acids (AHA/BHA), vitamin C, and retinal are best kept apart — alternate them across mornings and evenings, or across days, rather than stacking them in one sitting. See the layering map for what pairs safely with what.
Storing your products
- Keep everything in a cool, dry spot out of direct sunlight — a shelf away from the shower steam beats the windowsill or the car.
- Close caps and droppers tightly. Vitamin C keeps its potency longest sealed and away from heat.
- Water-light textures like essences and ampoules are best finished within their open-jar period.
- No need to refrigerate — but a sheet mask chilled for ten minutes is a nice touch in summer.
Reading the date on Korean packaging
Korean cosmetics print dates as year-month-day (for example, 2027.03.15), with two common markings:
- 까지 (kkaji) or EXP — use by this date.
- 제조 (jejo) — the date it was made, not the expiry.
The open-jar symbol (12M, 6M…) tells you how many months the product stays fresh once opened. Unsure about a marking on your bottle? Send us a photo and we'll read it for you.
A note on ingredients
Some of K-beauty's most-loved ingredients — snail mucin, propolis, honey — are animal-derived, so check the ingredient list on the product page if a fully vegan formula matters to you. Curious what snail mucin actually does? We wrote about it honestly here.
