Gbit Lab Buyer's Guide: EGF, Galactomyces, and Active Ampoules Explained
Gbit Lab is a Korean skincare brand offering active-ingredient ampoules and essences in practical, high-value sizes. The 7+ products currently in stock at skinsli.com span EGF wrinkle treatments, fermented galactomyces essences, a hyaluronic acid ampoule, a broccoli extract ampoule, and a vitamin C+E brightening ampoule. This guide explains each product, its primary active, and how to use the line.
The Gbit Lab Approach to Actives
Gbit Lab focuses on delivering recognized skincare actives - EGF, galactomyces ferment, hyaluronic acid, vitamin C - at functional concentrations in straightforward ampoule and essence formats. The brand's positioning is more ingredient-first than brand-story-first: the product names directly state the active and its percentage or effect rather than using proprietary names that obscure what is actually in the bottle.
A notable feature of the Gbit Lab line is its large-format options. The EGF ampoule and Galactomyces essences are available in 500ml sizes, which cuts the per-use cost substantially compared to typical 30ml or 50ml ampoules. This makes the brand practical for extended daily routines and for those who mix actives into other treatments at home.
EGF Wrinkle and Whitening Volume Ampoule: 100ml vs 500ml
The EGF Wrinkle and Whitening Volume Ampoule targets two concerns simultaneously: fine lines and skin brightness. EGF (epidermal growth factor) is a peptide-like protein that supports fibroblast activity, contributing to collagen synthesis and skin renewal. The "whitening" component refers to brightening - reducing the appearance of uneven tone and dullness rather than skin-lightening in a clinical sense.
The ampoule is available in both 100ml and 500ml sizes. The 100ml is a standard daily-use size; the 500ml is a professional-scale bottle that functions as a cost-effective long-term supply. Both contain the same formula. At 500ml, this is one of the most competitively priced EGF treatments available for daily face application, making it accessible for those who normally skip EGF due to cost.
Galactomyces 100 Essence 150ml and Galactomyces 90 Essence 500ml
Galactomyces ferment filtrate is a well-established K-beauty active derived from the same yeast fermentation process behind the discovery of Japanese sake brewery workers' famously smooth hands. It is a brightening, pore-refining, and texture-improving ingredient used in many premium Korean lines. Gbit Lab offers two variants: the Galactomyces 100 Essence at 150ml (indicating maximum galactomyces concentration) and the Galactomyces 90 Essence in a 500ml professional size (90% concentration).
The 100% essence at 150ml is a standard use format - apply a few drops or a small pump after cleansing and toning. The 90% at 500ml is the larger-supply version, suitable for daily full-face use over months. The 10-point difference in concentration is unlikely to be perceptible in day-to-day results; both deliver the core benefits of galactomyces at high saturation.
Hyaluronic Acid 100 Ampoule 100ml
The Hyaluronic Acid 100 Ampoule at 100ml is a pure hydration treatment. Hyaluronic acid (HA) is a humectant that binds water to the skin, supporting plumpness and surface smoothness. "100" in the Gbit Lab naming convention signals maximum or 100% concentration of the active within the formula. At 100ml this is a generous size for an HA ampoule - enough for several months of daily use.
HA ampoules sit well in most routines as the first serum step after toning. They layer compatibly with the brand's EGF and galactomyces products because all are water-based and humectant-focused. Apply to slightly damp skin to maximize the humectant effect, then follow with a richer serum or moisturizer to seal in the hydration.
Broccoli Extract 100% Ampoule 100ml
The Broccoli Extract 100% Ampoule is one of Gbit Lab's more distinctive offerings. Broccoli extract is a source of sulforaphane and glucoraphanin, compounds with antioxidant and anti-inflammatory properties. In skincare, broccoli-derived actives are used for protection against environmental stressors (pollution, UV-induced oxidative damage) and for general anti-aging support.
At 100ml the ampoule delivers the extract at a claimed 100% concentration, meaning the active is the dominant formula component rather than a trace addition. This suits use as a targeted treatment step in the evening, after toning and before moisturizing. It can be layered with the brand's EGF or Vita C+E ampoules depending on your primary concern - antioxidant support pairs particularly well with vitamin C.
Vita C + E 80 Ampoule 100ml
The Vita C + E 80 Ampoule combines two antioxidant vitamins - ascorbic acid (vitamin C) and tocopherol (vitamin E) - in a single 100ml formula. Vitamin C is the brightening and collagen-synthesis active; vitamin E is an oil-phase antioxidant that also stabilizes vitamin C, which degrades rapidly when exposed to air and light. The "80" in the name reflects the combined concentration level of these two actives.
This is an evening-use ampoule in most routines because vitamin C derivatives can increase photosensitivity if not properly buffered. Apply after toning, before moisturizer. The combination with vitamin E means the formula is more stable than a standalone vitamin C serum at the same concentration - and the 100ml size reduces the cost-per-use of a typically expensive brightening treatment.
Understanding the 500ml Professional Sizes
Gbit Lab's 500ml products - the Galactomyces 90 Essence and the EGF Wrinkle Ampoule - are intended for daily extended use or for professionals who apply products to multiple clients. For individual consumers, a 500ml ampoule-format product means roughly 6-12 months of supply at typical daily use rates, depending on how much you apply per session.
The trade-off with large formats is storage: once opened, water-based actives are best kept in a cool, dry location away from direct light. Both the galactomyces and EGF formulas are stable at room temperature for their stated shelf life, but humidity and heat accelerate degradation. If you live in a warm climate, refrigerator storage is worth considering for the 500ml bottles once opened.
Layering Gbit Lab Actives in a Routine
Gbit Lab products are all serum or essence format, so they sit in the post-toner, pre-moisturizer range of a routine. For a simplified stack, apply the Hyaluronic Acid ampoule first (lightest, pure humectant), then the Galactomyces essence (ferment-based, texture-refining), then the EGF ampoule (growth factor, slightly more substantive), and seal with moisturizer. The Broccoli Extract and Vita C+E ampoules substitute or supplement the EGF step depending on whether your focus for the evening is antioxidant protection or brightening versus volume support.
In the morning, finish with SPF - vitamin C and EGF both work alongside sunscreen as part of a comprehensive anti-aging morning routine. Avoid mixing the Vita C+E ampoule with niacinamide in the same step, as high-concentration vitamin C and niacinamide can form a complexion-yellowing byproduct (nicotinic acid) at high concentrations; keep them in separate steps if you use both.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What kind of brand is Gbit Lab?
Gbit Lab is a Korean skincare brand focused on active-ingredient ampoules and essences at high concentrations. Its product names state the active directly - EGF, galactomyces, hyaluronic acid, vitamin C+E - rather than using proprietary blend names. The brand is also notable for offering some products in 500ml professional sizes, which significantly reduces the per-use cost compared to standard 30ml-50ml ampoule formats.
What is the difference between the Gbit Lab EGF Ampoule 100ml and the 500ml version?
Both sizes contain the same EGF Wrinkle and Whitening Volume formula. The 100ml is a standard daily-use size; the 500ml is a professional or long-term supply option. At the larger size, the cost per milliliter drops substantially. There is no formula difference - the choice is entirely about how much supply you want and how you prefer to store it.
Should I choose the Gbit Lab Galactomyces 100 Essence 150ml or the Galactomyces 90 Essence 500ml?
The Galactomyces 100 Essence has a higher stated concentration (100%) in a standard 150ml size. The Galactomyces 90 Essence is slightly lower concentration (90%) but comes in a 500ml bottle. In practice, the 10-point difference in galactomyces percentage is unlikely to produce a perceptible results difference. If you use galactomyces daily and want the best value, the 90 Essence at 500ml is the cost-efficient choice. If you prefer a smaller, easier-to-store bottle and don't mind restocking more often, the 100 Essence at 150ml works well.
Can I use the Gbit Lab Vita C + E 80 Ampoule in the morning?
Vitamin C can increase photosensitivity, so morning use requires a high-SPF sunscreen applied afterward without exception. Most people use vitamin C ampoules in the evening to avoid the photosensitivity concern. If you prefer morning use, apply it before a broad-spectrum SPF 50 sunscreen and avoid prolonged sun exposure without reapplication.
What does the Gbit Lab Broccoli Extract 100% Ampoule do for skin?
Broccoli extract contains sulforaphane and related compounds with antioxidant and anti-inflammatory activity. In skincare, these protect against oxidative stress from UV exposure and environmental pollution, and support general skin resilience. The Gbit Lab Broccoli Extract Ampoule at 100ml uses the extract as the primary active rather than as a minor addition. It works well as an evening antioxidant treatment, particularly paired with a vitamin C serum or on its own for pollution-exposed skin.
When in my routine should I apply the Gbit Lab Hyaluronic Acid 100 Ampoule?
Apply it after cleansing and toning, before any heavier serums or moisturizer. Hyaluronic acid is a humectant that draws moisture to the skin's surface, so it benefits from being applied to slightly damp skin. Follow it with a serum or moisturizer that seals the hydration in place - an occlusive or emollient layer on top of HA makes it significantly more effective than using HA alone.
How should I store the Gbit Lab 500ml ampoule and essence bottles after opening?
Keep them in a cool, dry location away from direct sunlight. Room temperature storage is fine for both the Galactomyces 90 Essence and EGF Ampoule within their stated shelf lives. In hot or humid climates, refrigerator storage is worth considering once opened, as heat accelerates the degradation of water-based actives like EGF and ferment filtrate. Ensure the cap is sealed tightly after each use to minimize oxidation.
