Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that:

The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure.

Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.

Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.

Topically, glycerin does several things at once:

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Niacinamide is a multitasking form of vitamin B3 that strengthens the skin barrier, reduces pores and dark spots, regulates oil, and improves signs of aging.

And the best part? It's gentle and well-tolerated by most skin types, including sensitive and reactive skin.

You might have heard of "niacin flush", or the reddening of skin that causes itchiness. Niacinamide has not been found to cause this.

In very rare cases, some individuals may not be able to tolerate niacinamide at all or experience an allergic reaction to it.

If you are experiencing flaking, irritation, and dryness with this ingredient, be sure to double check all your products as this ingredient can be found in all categories of skincare.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

When you apply niacinamide to your skin, your body converts it into nicotinamide adenine dinucleotide (NAD). NAD is an essential coenzyme that is already found in your cells as "fuel" and powers countless biological processes.

In your skin, NAD helps repair cell damage, produce new healthy cells, support collagen production, strengthen the skin barrier, and fight environmental stressors (like UV and pollution).

Our natural NAD levels start to decline with age, leading to slower skin repair, visible aging, and a weaker skin barrier. By providing your skin niacinamide, you're recharging your skin's NAD levels. This leads to stronger, healthier, and younger looking skin.

Another name for vitamin B3 is nicotinamide. This vitamin is water-soluble and our bodies don't store it. We obtain Vitamin B3 from either food or skincare. Meat, fish, wheat, yeast, and leafy greens contain vitamin B3.

The type of niacinamide used in skincare is synthetically created.

  15. 15On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive.
  16. 16Another perk of this ingredient is that it stays functional across a wide pH range (3-10).
  17. 17You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own.
  18. 18Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU.
  19. 19Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up to 1%, including for children of all ages.
  20. 20Adverse systemic effects only showed up in animal studies at exposures roughly 200x higher than what people get from cosmetics. And despite its very widespread use, this ingredient is a rare sensitizer and allergic reactions are uncommon.

Why Top Researchers Choose GHK-Cu Copper Peptide

In the competitive world of biotechnology and cosmetic science, the integrity of your research materials is everything. That's why leading labs and institutions consistently turn to GHK-Cu copper peptide, a naturally occurring tripeptide that has become a cornerstone of regenerative research. Its unique relationship with copper ions gives it a remarkable ability to modulate cellular processes, making it a focal point for studies aimed at understanding and influencing tissue repair, skin health, and anti-aging mechanisms. First identified in human plasma, GHK-Cu levels are known to decline significantly with age, a fact that has spurred immense interest in its potential. For researchers in New York City, having access to a reliable supply of this compound means being able to conduct reproducible experiments that could lead to significant breakthroughs. The power of GHK-Cu lies in its multi-faceted biological activity. It's not just a single-action compound; it's a conductor, orchestrating a symphony of cellular responses. Key areas of study for GHK-Cu copper peptide include: Skin Remodeling and Collagen Synthesis: GHK-Cu is widely studied for its ability to stimulate the production of collagen and elastin, the foundational proteins for skin structure. Research explores its potential to improve skin firmness, reduce the appearance of fine lines, and promote a more youthful cellular matrix. This makes our GHK CU Copper Peptide a vital tool for dermatological and cosmetic formulation studies. Wound Healing and Tissue Regeneration: The peptide has demonstrated a profound ability to support the body's natural healing cascades. It's known to attract immune cells, stimulate angiogenesis (the formation of new blood vessels), and possess antioxidant and anti-inflammatory properties, creating an optimal environment for tissue repair. Gene Modulation: Perhaps its most fascinating property is the ability to modulate gene expression. Studies in 2026 continue to show that GHK-Cu can influence the activity of numerous genes, potentially resetting them to a more youthful state. This has far-reaching implications for longevity and cellular health research. But here's the critical part: none of this potential can be realized with impure or improperly synthesized peptides. The market is filled with suppliers offering subpar products that can compromise months, or even years, of research. This is where Real Peptides stands apart. We understand that for projects in New York City and beyond, there is no room for error. Our commitment is to unwavering purity and transparency. Every batch of our GHK-Cu copper peptide undergoes rigorous third-party testing to verify its identity, purity, and concentration. We provide you with the documentation you need to proceed with confidence. Unlike anonymous overseas sellers, we are a US-based company dedicated to supporting the American research community. When you source from us, you're not just buying a product; you're gaining a reliable partner.
