Fascy Lab

Fascy Lab is a Seoul-based skincare label focused on functional formulations rather than lifestyle branding. The name signals a lab-first orientation - products are built around a lead active ingredient and a clear skin concern rather than a broad multi-benefit claim. The brand sits in the mid-tier of Korean skincare: more precise than everyday drugstore lines, without the premium price of medical-grade ranges.

On skinsli.com, Fascy Lab products ship directly from authorized Korean supply chains, which means you receive the same formulas sold in Korean pharmacies and beauty retailers.

The Collagen Ampoule is the anchor SKU in the Fascy Lab lineup at skinsli.com. Packaged in a 30ml bottle, it delivers hydrolyzed collagen alongside supporting humectants to address early signs of laxity and dullness. Collagen molecules at varying molecular weights target both surface-level smoothness and deeper moisture retention.

This ampoule works well pressed into skin after a toner and before a moisturizer. It layers without pilling under heavier creams, and its texture - slightly viscous but not tacky - suits most skin types, including combination. A 30ml bottle lasts roughly four to six weeks at one to two daily uses.

The Sika AC Solution Ampoule targets blemish-prone and sensitized skin through a centella asiatica (cica) base combined with AC-calming actives. "Sika" is a shorthand for the centella extract central to the formula; "AC" refers to acne-concern support. Together, they make this ampoule useful during breakout cycles, post-extraction recovery, or as a preventive treatment for skin that tends toward congestion.

At 30ml, the format and size mirror the Collagen Ampoule, which means the two can be alternated or layered depending on the day's concern. The cica-heavy formula is gentle enough for sensitive skin, making it a good pick for anyone whose skin reacts to stronger actives like retinol or AHAs.

The Lollipop Lip Balm rounds out the Fascy Lab range at skinsli.com with a straightforward moisture treatment for lips. At 3.9g, it is a standard twist-up balm format suitable for daily carry. The formula uses emollients and film-formers to seal moisture against chapping and dryness without a heavy waxy feel.

The "lollipop" name is a nod to its scented or flavored character - a common approach in Korean lip care, where the product is positioned between a functional treatment and a light tinted balm. It fits naturally at the end of a skincare routine or as a standalone daytime lip step.

Both Fascy Lab ampoules follow standard K-beauty serum placement: apply after cleansing and toning, before your moisturizer or cream. Start with 2-3 drops warmed between palms, then press gently into skin rather than rubbing. Allow 30-60 seconds for the formula to absorb before layering the next step.

If you are using both the Collagen Ampoule and the Sika AC Solution, layer the lighter-textured one first. On most skin types, the AC Solution is thinner and goes on before the Collagen Ampoule. On blemish days, you can concentrate the AC Solution on affected zones only, then apply the Collagen Ampoule across the full face as a base treatment.

The Collagen Ampoule is broadly compatible. Dry and combination skin benefit most from the humectant-collagen blend, and the lightweight texture means it does not create heaviness under a moisturizer even for oilier skin types. Normal skin can use it year-round as a general firmness and hydration booster.

The Sika AC Solution Ampoule is especially well suited to oily, blemish-prone, and sensitive skin. Centella-based formulas are among the mildest actives in Korean skincare, making this ampoule a safe introduction for skin that reacts to most treatments. It is also a good option for post-procedure recovery (after peels or microneedling) when the skin barrier is temporarily compromised.

Ampoules are a standard format in Korean skincare: higher active concentration than a toner, more targeted than a general serum, and more portable than a cream treatment. The 30ml size used by Fascy Lab is a practical middle ground - large enough for a one-to-two month supply but small enough to travel with.

Unlike some Western serums that combine many actives, Korean ampoules tend to feature one lead ingredient at meaningful concentration. This makes them easier to stack with other products and easier to troubleshoot if you experience a reaction - you know which active to credit or remove.

Fascy Lab products on skinsli.com are sourced through direct Korean supply chains. The batch codes on each item can be cross-checked against Fascy Lab's official records. If you receive a product that shows signs of tampering or inconsistent packaging, skinsli.com's returns process handles the exchange.

Korean cosmetics sold in the US are required to list ingredients in English per FDA labeling rules, so the Fascy Lab items at skinsli.com carry compliant English-language ingredient lists alongside the original Korean text on the packaging.
