What is the major advantage of using a non-injected HA hydration booster serum?
The major advantage of using this serum is its ability to deliver intensive, filler-like hydration and plumping effects without the need for injections. It provides a safe, non-invasive solution that offers instantly visible improvements in skin moisture, smoothness, and elasticity.
How does this serum differ from other regular hydration products?
Unlike typical hydration products that focus only on surface moisture, this GTA™ formula-based hydration booster antiwrinkle serum combines an engineered complex of five different types of hyaluronic acid with GTA™ ingredients—alpha-ketoglutarate, ascorbic acid, gallic acid, and collagen tripeptide. These components work synergistically as a 3D hydration matrix to target the epidermis, dermis, and subdermal layers. This unique formulation significantly increases and retains skin moisture and collagen production, providing immediate and long-lasting inside-out hydration and collagen enhancement in a non-injected HA booster manner to reduce fine lines and wrinkles, giving the skin a smoother, plumper appearance.
How soon will I see results?
You can expect to see an immediate improvement in skin hydration after applying this serum. As quickly as five minutes after application, the skin’s aging level is reduced, as measured by the Idunn’s Apple Skin Aging Test. Texture and radiance typically improve within three to four weeks. With continued use, results include enhanced tone, firmness, and overall skin vitality.
Does this serum contain harmful ingredients?
Not at all. Our formula is crafted with EWG Green-rated ingredients (low hazard rating of 1–2) and is free from parabens, synthetic fragrances, and other harsh additives.
Can this serum be used with your other products or my current skincare routine?
Yes! This serum can be used with our other antiaging products as part of a targeted skincare module for optimal results. It also layers well under most skincare and makeup products. For best results, use it after cleansing and before applying your moisturizer or sunscreen.
How should I store this product to prevent color change since it contains vitamin C?
This serum can be stored at room temperature. Unlike many other vitamin C serums that turn yellow after a few weeks due to oxidation, this formula remains clear and stable. Its unique stabilized vitamin C complex and oxidation- and light-resistant packaging help maintain freshness and effectiveness over time.
