Gouri is a liquid skin booster that helps restore elasticity by regenerating collagen in the skin. The key difference from existing products, which used powder that had to be dissolved, is that Gouri is liquid from the start. As it's a notable product in the recent skin booster market, we will analyze the principles by which it replenishes the skin. We will also briefly share some content from our own research, which is awaiting publication in an academic journal.
1st and 2nd Generations, and the Liquid 3rd Generation
Skin boosters have evolved through generations. The core differences lie in what they replenish and how they are administered.
- 1st generation uses hyaluronic acid, which provides volume to areas but has less collagen regeneration effect.
- 2nd generation is a collagen skin booster that creates new collagen, but most are in powder form and are diluted with liquids like saline solution.
- Gouri, being liquid from the start, has the biggest advantage of spreading evenly in the skin.
Powder-based products that need to be dissolved can clump in one area or be injected too much at once. In contrast, liquid spreads well when injected, evenly increasing collagen density.
Spreads Evenly Without Forceful Filling
Gouri does not forcefully fill the skin; instead, when injected, it spreads well on its own, increasing collagen density. As a result, you can understand it as a booster that provides overall elasticity to the face and subtly lifts sunken tissues.
Liquid Structure with Fewer Nodule Concerns
The most helpful aspect of using a 3rd generation booster is its safety. If powder clumps in one area or gathers in the skin, nodules can form, and these can press on surrounding blood vessels, leading to vascular issues.
Gouri is a liquid with very small particles, so it spreads well when injected and does not clump. Therefore, it has a structure that makes it difficult for changes like nodules to occur, even if they were to try. To date, we are not aware of any nodule reports.
Although it is not intentionally injected into blood vessels, even if some enters, it is designed not to cause major problems because it is liquid. However, as it is an injection procedure, bruising may occur.
Quick Return to Daily Life with One or Two Injection Points
Gouri typically uses the cannula method. Since it is injected at only one or two points on the face, there is less pain and bruising, no separate massage is required, and daily life is possible approximately six hours after the procedure. The ingredient itself has also been verified over time, and its effectiveness is well-known.
Prioritize What Suits Your Skin Over Trends
Gouri is primarily European-certified and has recently received domestic certification. Clinical data from our own research also shows good results for this booster. However, how the same product is used can determine the outcome.
- We don't just inject; we design the appropriate amount and location according to your face shape.
- Based on our expertise in scar regeneration, we utilize laser, radiofrequency, and ultrasound devices together.
- We customize the procedure to each individual's skin.
When it comes to skin boosters, it is most important to consider whether they can accurately address the deficiencies in your skin and whether they are safe, rather than just following trends.
Results may vary by individual, and accurate diagnosis and treatment are determined after consultation.
