 	\<li\>Intense Hydration: Hyaluronic acid, an ingredient known as the most potent moisturing factor in the body\. HA can hold up to 1000 times its weight in water, making it a powerful humectant\.  Qualitide's  \<em\>\<strong\>Copper Peptide Serum\</strong\>\</em\> formula contains both high molecule weight \(HMW\-HA\) and low molecule weight ofhyaluronic acid \(LMW\-HA\)\. The HMW\-HA will create a moisturing layer on the surface of skin while LMW\-HA can be absorpted and retains the water underneath the skin\. Together, the formula provides long\-lasting moisture contributing to tissue elasticity, suppleness and plumpness\.\</li\>
 	\<li\>Premium Quality \& Transparency: Crafted with top\-tier ingredients for optimal skin benefits, produced in a GMP\-certified facility in the USA, and backed by third\-party lab tests to ensure clarity on active ingredients\.\</li\>
\</ul\>
- [Eyelitide™ Complex Solution](https://qualitide.com/product/eyelitide-complex-solution/): Eyelitide Complex Solution is a high\-end cosmetic peptide composite developed by Qualitide\. It contains 7 highly active essential peptides, which can comprehensively solve eye problems \(eye wrinkles, eye bags and dark circles\)\.
\<ul\>
 	\<li\>\<em\>\<strong\>Dipeptide\-2:\</strong\> is a peptide that promotes the drainage of fluid that collects under the eye creating bags and puffiness\.\</em\>\</li\>
 	\<li\>\<em\>\<strong\>Acetyl Tetrapeptide\-5:\</strong\> is a synthetic peptide with anti\-oedema action that helps reduce the look of puffy eye bags and dark circles under the eyes and helps prevent them from reappearing\. It has the sequence Ac\-βAla\-His\-Ser\-His, known under the trade name Eyeseryl\.\</em\>\</li\>
 	\<li\>\<em\>\<strong\>Dipeptide Diaminobutyroyl Benzylamide Diacetate:\</strong\> \</em\>aka, Syn\-Ake\<em\>\<sup\>®\</sup\>\</em\> is a cutting\-edge wrinkle treatment, thanks to a remodeled synthetic tripeptide, derived initially from snake \(Temple Viper\) venom, Waglerin\-1\. Mimicking the effect of Waglerin\-1, this peptide relaxes muscle movement by temporarily immobilizing facial contractions that cause facial lines and wrinkles\. It reduces muscle contractions by up to 80% \(in vitro results\) due to the disabling of the muscular nACh receptors\. Moreover, due to the reduction in micro\-contractions, a significant smoothing effect can already be noticed after 28 days, accompanied by a considerable decrease in skin wrinkles, all without altering the natural radiance of the face in the process\.\</li\>
 	\<li\>\<em\>\<strong\>Acetyl Hexapeptide\-8 \(Argireline\):\</strong\>  \</em\>Argireline® defined the mechanisms of action of botulinum toxin, laid out the molecular foundations for expression wrinkle formation\. The sequence of the peptide is Ac\-Glu\-Glu\-Met\-Gln\-Arg\-Arg\-NH2\. The anti\-wrinkle activity has led to this revolutionary Hexapeptide\-3 which has taken the cosmetic world by storm\.\</li\>
 	\<li\>\<em\>\<strong\>Palmitoyl Tetrapeptide\-7:\</strong\> Lipopeptide Pal\-GQPR \(Matrixyl™\)\</em\> is another peptide that decreases inflammation, improves skin elasticity and firmness, and reduces fine lines and wrinkles\.\</li\>
 	\<li\>\<em\>\<strong\>Palmitoly Tripeptide\-1:\</strong\> \</em\>Palmitoyl Tripeptide\-1 stimulates fibroblasts and enhances the production of collagen and GAGs, smoothing fine lines and deep wrinkles and improving the water\-binding ability and elasticity of the skin\.\</li\>
 	\<li\>\<strong\>\<em\>Palmitoyl Tripeptide\-5 \(aka Syn\-Coll\<sup\>®\</sup\>\)\</em\>\</strong\> is highly bioactive, deeply skin penetrating peptide able to activate tissue growth factor \(TGF\-beta\) that stimulates collagen synthesis in the skin\.\</li\>
\</ul\>
These highly active biologics work synergistically and therefore significantly improve skin texture and increase skin elasticity within 1 to 3 skin growth cycles; two ACE enzyme inhibitor peptides fight eye face edema and solve eye bags and dark circles in 15 days\.
- [Eyeliss Complex Solution](https://qualitide.com/product/eyeliss-complex-solution/): \<div class="block block\-layout\-builder block\-field\-blocknodeingredientbody"\>

Eyeliss complex solution consists of three biologically active ingredients:  Dipeptide\-2 \(Valyl\-Tryptophane; Dipeptide\-VW\); a lipopeptide Palmitoyl Tetrapeptide\-7 \(Pal\-GQPR\) andHesperidin methyl chalcone\. The combination together improves fluid drainage, reduces capillary fragility, and lowers irritation and skin slackening while increasing skin firmness and elasticity\.
\<ul\>
 	\<li\>\<span style="text\-decoration: underline;"\>\<strong\>Dipeptide\-VW\</strong\>\</span\> inhibits of Angiotensin\-Converting Enzyme \(ACE\), promoting local lymphatic circulation\.\</li\>
 	\<li\>\<span style="text\-decoration: underline;"\>\<strong\>Palmitoyl Tetrapeptide\-7\</strong\>\</span\> regulates UV\-induced IL6 production by keratinocytes, soothing irritation and additionally enhancing skin smoothness, firmness, and elasticity\.\</li\>
 	\<li\>\<span style="text\-decoration: underline;"\>\<strong\>Hesperidin methyl chalcone\</strong\>\</span\> stabilizes microvessels reducing the capillary permeability\.\</li\>
\</ul\>
Thanks to the targeted triple effects, Eyeliss Complex Solution provides a synergistic remedy for fighting against \<strong\>puffy eyes, dark cycles, and eye bags\</strong\>\. It is crafted as ready\-for\-use solution suitable for adding to various formulations, including eye patches, creams, gels, and lotions\.
