- [Tetrapeptide\-30](https://qualitide.com/product/tetrapeptide-30/): \<strong\>Tetrapeptide\-30\</strong\> is a synthetic skin\-active peptide derived from the KEK motif found in the natural antimicrobial polypeptide \<em\>cathelicidin\</em\>\. This multifunctional tetrapeptide is designed to reduce hyperpigmentation, boost skin firmness, and promote cell renewal — making it an ideal ingredient for both anti\-aging and skin\-brightening formulations\.

\<strong\>Key Benefits of Tetrapeptide\-30\</strong\>
\<ul\>
 	\<li\>\<strong\>Hyperpigmentation Control: \</strong\>Unlike standard tyrosinase inhibitors, \<strong\>Tetrapeptide\-30\</strong\> targets the upstream triggers of melanogenesis, specifically inflammatory cytokines \(IL\-6 and IL\-8\) and α\-MSH production\. This helps fade UV\- or inflammation\-induced dark spots, melasma, and post\-inflammatory hyperpigmentation \(PIH\)\.\</li\>
\</ul\>
\<ul\>
 	\<li\>\<strong\>Skin Cell Renewal: \</strong\>By soothing inflammation and supporting a healthy epidermal environment, Tetrapeptide\-30 promotes skin cell turnover, improving tone, texture, and clarity over time\.\</li\>
\</ul\>
\<ul\>
 	\<li\>\<strong\>Skin Brightening Without Irritation: \</strong\>Reduces hyperchromatic age spots and evens out skin tone without triggering sensitivity\. Excellent for all skin types, including sensitive, Asian, and melanated skin tones\.\</li\>
\</ul\>
\<ul\>
 	\<li\>\<strong\> Skin Firmness: \</strong\>While reducing pigmentation, Tetrapeptide\-30 also improves skin firmness and elasticity, making it a multifunctional option for anti\-aging skincare\.\</li\>
\</ul\>
- [Tripeptide\-29 \(Collagen Peptide\)](https://qualitide.com/product/tripeptide-29-collagen-peptide/): Tripeptide\-29 is a synthetic biomimetic peptide that significantly improves collagen synthesis promoting wrinkle reduction, firming, and skin plumping\. It is known under the trademark AC Collagen Prepeptide PF\.

Collagen is a long\-chain polymer made of short monomeric repeats that are generally made up of three amino acids in sequences\. Collagen subunit almost always follows the pattern of Gly\-Pro\-X or Gly\-X\-Hyp\. Tripeptide\-29 is a Gly\-Pro\-Hyp peptide, making it a perfect synthetic analogue of common collagen building blocks\. Thanks to a small molecular weight of 285 D, Tripeptide\-29 exhibits increased bioavailability and easily penetrates deeper layers of the skin\. Reaching dermal fibroblasts, stimulates those cells enhancing collagen synthesis activity\.

Increased collagen production improves DHJ \(dermal\-epidermal junction\) integrity and scaffolding matrix\. Tripeptide\-29 is a safe and effective ingredient for anti\-aging preparations formulated to boost collagen production and expose a youthful, healthy, and radiant appearance\. It is usually used in 0\.1 – 1\.0% concentration\.
- [Palmitoyl Tetrapeptide\-7 \(Rigin™, Lipopeptide\)](https://qualitide.com/product/palmitoyl-tetrapeptide-7-rigin-lipopeptide/): \<strong\>Palmitoyl Tetrapeptide\-7\</strong\>, also known as \<strong\>Rigin™\</strong\> \(formerly Palmitoyl Tetrapeptide\-3\), is a clinically studied lipopeptide developed by Sederma\. It is recognized for its ability to promote skin balance, support collagen structures, and reduce visible signs of aging, especially in mature and sensitive skin types\.

\<strong\>Palmitoyl Tetrapeptide\-7 Rigin Benefits\</strong\>
\<ul\>
 	\<li\>\<strong\>Skin firming support\</strong\> – Promotes a firmer, more youthful texture\</li\>
 	\<li\>\<strong\>Rigin peptide\</strong\> \<strong\>Collagen production assistance\</strong\> – Helps encourage healthier extracellular matrix structure\</li\>
 	\<li\>\<strong\>Anti\-inflammatory activity\</strong\> – May reduce markers of irritation in the skin\</li\>
