Skin Conditioning, Solvent

1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. 

It is a:

  • Humectant, drawing moisture into the skin
  • Emollient, helping to soften skin
  • Solvent, dispersing and stabilizing formulas
  • Preservative booster, enhancing the antimicrobial activity of other preservatives 
Humectant, Skin Conditioning

Acetyl Hexapeptide-8, commonly known as Argireline, is a popular peptide in skincare. It’s often referred to as a “Botox-like” ingredient because it helps reduce muscle movement.

By relaxing these micro-movements, Argireline may help minimize the appearance of fine lines and wrinkles. That said, it’s not as powerful as Botox, and research on its long-term effectiveness is still limited.

Beyond smoothing, Argireline may also support collagen production. Collagen is the protein that helps keep your skin firm, bouncy, and well-hydrated by strengthening the skin barrier.

So while Argireline isn’t a miracle fix, it can be a helpful addition to a routine focused on both prevention and skin health.

Humectant, Skin Conditioning

Acetyl Octapeptide-3 is a synthetic peptide also commonly known as SNAP-8. It is a lab-made peptide often marketed as a gentler, topical alternative to Botox.

It works by mimicking part of a protein involved in muscle contractions, which may help relax facial tension and reduce the appearance of fine lines (mostly around the eyes and forehead).

It’s considered a “next-gen” version of Argireline (Acetyl Hexapeptide-8), an older peptide with more research behind it that also supports collagen production.

SNAP-8 showed slightly better results than Argireline in one small manufacturer-funded study, but there’s limited independent research. Plus, most tests use concentrations higher than what’s typically found in skincare products.

This ingredient might offer a subtle smoothing effect but it won't don’t deliver the dramatic results of actual Botox injections.

Think of it more like a supporting actor in your skincare lineup.

Skin Conditioning

This peptide is more commonly known as Thymulen 4 BG.

It is derived from a youth hormone called thymopoietin. Thymopoietin helps regulate the immune system and decreases naturally with age.

According to the manufacturer, this peptide boosts the skin's immune defenses and regenerates the outer layers of skin.

Skin Protecting

This biometic peptide is designed to support hair growth.

According to a manufacturer, it stimulates hair growth by:

The manufacturer has found combining this ingredient with red clover extract (Capixyl) boosted benefits. Not only does it enforce the scalp's extracellular matrix, it also inhibits the enzyme that creates DHT, a hormone that leads to hair loss.

While this ingredient is promising, more research is still needed to confirm its full effectiveness.

Acetyl Tetrapeptide-5 is a peptide that goes by another name, eyeseryl, due to claims that it can help reduce eye puffiness.

The manufacturer claims this ingredient reduces eye puffiness by:

An in-vivo study from the manufacturer found 95% of volunteers saw eye bag improvement by the end of the study.

Eye puffiness is caused by two major factors: fluid retention and fat.

Those with fluid retention may see improvement from using this ingredient. However, those with eye fat will need surgical intervention in order to get rid of puffiness.

Skin Conditioning

Acetyl Tetrapeptide-9 is a signal peptide. Signal peptides tell your skin to create collagen or start tissue repair.

This peptide plays a role in key skin components such as collagen, lumican, and glycosaminoglycans (GAGs). Lumican is used in collagen organization and regulation, while GAGs are a component that holds water in our skin.

The manufacturer claims this ingredient is effective at firming the skin and enhancing skin hydration.

Skin Conditioning

Adenosine is in every living organism. It is one of four components in nucleic acids that helps store our DNA.

Adenosine has many benefits when used. These benefits include hydrating the skin, smoothing skin, and reducing wrinkles. Once applied, adenosine increases collagen production. It also helps with improving firmness and tissue repair.

Studies have found adenosine may also help with wound healing.

In skincare products, Adenosine is usually derived from yeast.

Skin Conditioning, Skin Protecting, Soothing

Allantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.

Some studies have shown this ingredient can promote wound healing with higher concentrations.

Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.

Humectant, Masking, Skin Conditioning

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

Skin Conditioning

Copper Tripeptide-1 (GHK-Cu) is a skin repairing ingredient known for its ability to boost collagen, improve firmness, and support skin regeneration.

It is a complex made up of a naturally occurring peptide (glycine-histidine-lysine) and copper, an essential trace element.

While studying wound healing, researchers noticed GHK-Cu stimulated hair follicle enlargement and growth by keeping hair in its active growth phase longer. This has made it a promising ingredient for hair regrowth treatments.

Some people have reported increased facial hair. While GHK-Cu can make your hair follicles bigger, it usually doesn’t turn soft, barely-visible facial hairs into thick, dark ones.

Anecdotal reports suggest that overusing copper peptides might lead to premature aging due to excess free copper or enzyme imbalances. This claim isn’t backed by large-scale studies.

Unfortunately, there are limited human studies for this ingredient. While early results are promising, many studies are either small, in-vitro, or not rigorously controlled.

For example, there is a 1998 study that explored the effects of copper tripeptide, vitamin C, tretinoin, and melatonin on skin repair and collagen synthesis.

After one month, increased procollagen production was seen in 7 out of 10 participants using copper tripeptide (more than those using vitamin C, melatonin, or tretinoin.

While the study was exploratory, it offers early evidence that copper tripeptide may support collagen production. Larger, well-designed trials are still needed to confirm its potential and understand individual responses.

Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.

You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.

Humectant, Skin Conditioning, Skin Protecting

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

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

Emollient, Humectant, Skin Conditioning

Hydrolyzed collagen has a misleading name because it is actually a mixture of various proteins/peptides. This ingredient has skin hydrating properties.

Collagen is the most abundant type of structural protein found in your body. In your skin, it is responsible for keeping it firm and youthful.

Hydrolyzed Collagen is created by breaking up proteins into smaller peptide bonds. These peptides act as humectants and emollients.

Humectants are great at holding onto water, keeping skin hydrated. Emollients create a thin barrier on the skin to prevent moisture from escaping.

There is ongoing debate about whether hydrolyzed collagen works because it increases skin hydration. Skin hydration is also linked to elasticity and the appearance of wrinkles.

Collagen or peptide ingredients can be used in the morning or night. They will not increase sun sensitivity, but you should always wear sunscreen during the day.

According to a manufacturer, this ingredient is a great hair conditioner as well.

This ingredient can be extracted from different sources, including:

Vegan collagen is derived from yeast, bacteria, or plant sources. Vegan collagen would go by a different INCI name, such as hydrolyzed soy protein.

The results are varied.

A study from 2021 found hydrolyzed collagen increased elasticity and improved wrinkles in 1,125 participants between age 20 and 70. Another study found increased skin thickness in participants between the ages of 45 to 59.

However, It is difficult to prove that oral collagen will end up working on your skin. Many of the studies using hydrolyzed collagen also add several vitamins and nutrients into the test mixture as well.

Further studies are needed at this time.

Methylpropanediol is a synthetic solvent and humectant.

As a solvent, it helps dissolve other ingredients, helping to evenly distribute ingredients throughout the product. This ingredient has also been shown to have antimicrobial properties which makes it a preservative booster.

Methylpropanediol is able to add a bit of moisture to the skin. It also helps other ingredients be better absorbed into the skin, such as salicylic acid.

Smoothing

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.

Skin Conditioning

Nonapeptide-1 is created from amino acids including arginine and lysine.

It has antioxidant and antimicrobial properties.

Emerging studies show Nonapeptide-1 to help with reducing pigmentation and brightening the skin. It has shown to prevent the activation of tyrosinase, an enzyme in the skin that begins the process of melanin creation. Melanin is responsible for giving skin a tan or dark spots.

You might know this ingredients as Matrixyl, a famous peptide.

Peptides are building blocks for protein. Palmitoyl Pentapeptide-4 consists of five amino acids. These amino acids include: 2 lysines, 2 threonines, and serine

This ingredients tells our body to create more collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.

Thus, Matrixyl may help improve the look of wrinkles.

Skin Conditioning

Palmitoyl Tripeptide-1 is also known as pal-GHK. It is made up of 3 amino acids and palmitic acid, a fatty acid that helps it absorb into skin more easily.

This peptide is as a signal peptide, meaning it tells the skin to produce more collagen. Collagen is the key protein that helps form the skin's structure and keep it plump, firm, and hydrated.

By boosting collagen production, this ingredient supports a stronger skin barrier and helps reduce the appearance of wrinkles.

You'll most likely see this ingredient paired with Palmitoyl Tetrapeptide-7 in the well-known Matrixyl 3000 complex. While results from in-house testing should be viewed cautiously, this peptide duo is among the most studied and widely used in modern skincare.

Due to its palmitic acid base, this ingredient may not be safe for Malassezia folliculitis.

Skin Conditioning

This synthetic peptide is created from lysine, valine, and palmitic acid.

According to the manufacturer, in-vitro studies show tissue growth and collagen synthesis. Another in-vivo study found 60 volunteers saw a significant reduction in wrinkles after 84 days.

Due to its palmitic acid base, this peptide may not be fungal-acne safe.

Learn more about Palmitoyl Tripeptide-5
Skin Conditioning

Panthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.

There are two forms of panthenol: D and L.

D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.

Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):

Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.

This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.

Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

This ingredient is also referred to as pro-vitamin B5.
