Oligopeptide 34 Injection is a small-molecule functional cosmetic active peptide synthetically produced from 13 specific amino acid sequences. It belongs to the category of high-end skincare peptide ingredients and is designated as "Oligopeptide-34" under the INCI standard. It is recognized in the cosmetics and skincare industry as a key ingredient for gentle skin tone correction and anti-aging. Unlike macromolecular peptides and plant extracts, Oligopeptide-34, based on its precise amino acid sequence structure, possesses core characteristics such as low molecular weight, strong skin permeability, high biocompatibility, and precise targeting.It can penetrate the epidermal layer without the need for complex permeation-enhancing systems,
acting on melanocytes and basal skin cells to achieve targeted skincare benefits, without the irritation or dependency associated with traditional skin-lightening ingredients.From the perspective of its core mechanism of action, Oligopeptide-34 primarily delivers skincare benefits through three targeted pathways: First, it downregulates the expression of MITF, TRP-1, TRP-2, and tyrosinase, thereby inhibiting melanin synthesis in melanocytes at the source and blocking the core pathway of pigment formation; Second, it inhibits the assembly of melanosomes and their transport to keratinocytes, preventing the layer-by-layer deposition of pigment that leads to dark spots, dullness, and uneven skin tone;third, it helps soothe mild skin inflammation, repair the skin barrier,
and improve post-inflammatory hyperpigmentation, addressing the skin tone correction needs of all types of sensitive skin. Data from authoritative dermatological laboratory tests show that Oligopeptide-34 can effectively reduce tyrosinase activity by approximately 65% and decrease melanin production by up to 33%. At equivalent application concentrations, its pigmentation-improving effects outperform classic brightening ingredients such as conventional vitamin C and arbutin, while offering superior safety.As a compliant cosmetic-grade ingredient, Oligopeptide-34 is free of hormones, heavy metals, and irritating chemical additives.
It meets domestic and international safety standards for cosmetic ingredients and is widely compatible with formulation systems for all skin types, making it a core category in the current evolution and upgrading of functional skincare ingredients. Bloomtechz, a professional brand specializing in the R&D, production, and sales of peptide ingredients, has been deeply involved in the oligopeptide-34 field for many years. Leveraging its independently developed and continuously improved production technology, standardized quality control system, and professional technical team, the company has created high-purity, highly stable, and highly active Oligopeptide 34 raw material products. It provides global skincare manufacturers and R&D institutions with one-stop raw material supply, formulation adaptation,
one-on-one technical consultation, along with comprehensive batch quality testing reports.By ensuring the stability of end-product quality from the raw material source, and backed by a robust supply chain system and an exceptional sales team, Bloomtechz has established itself as a reliable supplier of Oligopeptide-34 in the industry.
Thanks to its gentle yet highly effective nature, broad compatibility, and strong adaptability, Oligopeptide 34 Injection is primarily used in the performance skincare sector, spanning multiple segments such as consumer skincare, professional salon treatments, and customized skincare. It is compatible with the vast majority of skincare formulations-including toners, serums,
moisturizers, masks, and concentrated essences-making it a core, versatile ingredient in performance skincare products.In the consumer skincare sector, Oligopeptide-34 is primarily used to brighten the complexion, improve dullness, even out skin tone, and fade superficial dark spots and acne scars.It is suitable for the daily care of skin affected by late nights, dullness, and hyperpigmentation. Long-term, proper use can gradually improve uneven skin tone and yellowish skin tone. At the same time, thanks to its mild anti-inflammatory and reparative properties, it can help alleviate dullness caused by seasonal sensitivity, balancing efficacy with gentleness.In the field of professional salon skincare,
Oligopeptide-34 is commonly used for post-procedure repair and specialized treatment of pigmentation issues. It addresses problems such as mild inflammatory hyperpigmentation following laser and light-based aesthetic treatments, stubborn post-sun exposure dullness, and uneven skin tone during the recovery phase of "hormone-induced facial skin" conditions. It can be formulated in combination with other reparative ingredients to to repair the skin barrier while blocking pigment deposition, thereby reducing the risk of post-treatment hyperpigmentation.It is the preferred ingredient for gentle pigment correction in professional skincare settings.Compared to potent ingredients such as hydroquinone and high-concentration acids,
Oligopeptide-34 is non-exfoliating and non-corrosive; it does not damage the skin's stratum corneum structure and is suitable for long-term, sustained treatment, aligning with the current skincare consumer trend of "gentle efficacy and nourishing, brightening care."
In addition, Oligopeptide-34 is compatible with a variety of skincare ingredients, including hyaluronic acid, panthenol, hexapeptide, and ergothioneine, allowing for expanded applications in anti-aging skincare, barrier-repairing skincare, and body care products designed to brighten the skin, thereby delivering a combination of "brightening, repair, and anti-aging" benefits.Furthermore, this ingredient is suitable for a variety of formulations,
including aqueous solutions, emulsions, creams, and freeze-dried powders. It has a low formulation barrier and can be scaled up for mass production without requiring special process modifications, significantly reducing product R&D and mass production costs for brands. Leveraging its mature technical support system, Bloomtechz provides partner clients with exclusive formulation solutions, formulation optimization, and guidance on process implementation.

Frequently Asked Questions
1: What are the key advantages of Oligopeptide-34 compared to niacinamide and arbutin?
+
-
Oligopeptide-34 regulates melanin production and transport by targeting specific cellular pathways. It does not exfoliate the stratum corneum, does not irritate the skin, and is non-photosensitizing. Compared to niacinamide, it is less likely to cause redness or skin intolerance, and compared to arbutin, it is more stable and less prone to oxidation and inactivation. Bloomtechz provides comprehensive comparative testing reports and one-on-one formulation guidance to support the development of various functional products.

+
-
Oligopeptide-34 is resistant to high and low temperatures and has a wide pH tolerance range. It remains stable at standard emulsification temperatures and within the pH ranges of conventional skincare formulations. It does not require low-temperature processing or light-protected production; it can be stored long-term at room temperature in a sealed container without becoming inactive or discolored. Bloomtechz employs a modified solid-liquid phase synthesis process, ensuring minimal batch-to-batch variation and consistent purity.
3: Does Oligopeptide-34 have any side effects? For which skin types and scenarios is it suitable?
