Ingredients Explained

These ingredients are found in both products.

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

Caprylic/Capric Triglyceride (aka MCT Oil) is a lightweight emollient, solvent, and texture enhancer. It is considered a skin-softener by helping to prevent moisture loss.

Though it behaves like an oil, it is not technically one due to its chemical composition. One perk of this ingredient is that it is very stable, resistant to oxidation, and unlikely to go rancid.

In practice, that translates to a long shelf life and a consistently elegant skin feel.

While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this. Just patch test if you have concerns.

Fractionated coconut oil and MCT Oil are both listed as Caprylic/Capric Triglyceride according to INCI. This is because INCI names are based on the ingredient’s final chemical composition and not its marketing name or source.

This ingredient is treated as the gold standard fungal acne safe oil. Even though it is coconut derived, the problematic lauric acid is stripped out.

This leaves just caprylic (C8) and capric (C10) acid. These chain lengths actually trend antifungal; a 2020 study found caprylic acid was enough to disrupt Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%.

Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created.

Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin.

Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).

Cetearyl alcohol is a waxy mixture of two fatty alcohols: cetyl alcohol and stearyl alcohol. It is an emollient and emulsifier.

Despite having "alcohol" in its name, it has nothing to do with drying solvent alcohols; the FDA also allows "alcohol-free" products to contain fatty alcohols like this ingredient.

It plays several roles in a formula:

Typical use levels for this ingredient sit around 1-10% and the Cosmetic Ingredient Review Expert Panel has affirmed safety at concentrations up to 25% in leave-on products.

Multiple assessments have found it to be non-irritating and non-sensitizing to most people.

However, there have been some cases of allergic contact dermatitis in patients with chronically compromised skin barriers.

Cetearyl alcohol has a comedogenic rating of 2 and irritancy rating of 1. Both of these numbers come from the 1989 study that used rabbit ears; a "2" means mildly comedogenic and a "1" means low irritancy.

Here's the catch: rabbit skin is more sensitive than human skin and throws a lot of false positives. A 1996 reappraisal found that ingredients rated 1-2 in the rabbit ear tests are generally safe for humans.

Remember comedogenic ratings are unable to assess the entire formula of a product or how it will react on your skin. Just be sure to patch test if you are unsure about certain ingredients.

This ingredient is not fungal acne safe. Cetearyl alcohol is a fatty alcohol with chain lengths that fall within the range that Malassezia can metabolize.

A 2019 study has also observed Malassezia growth in the presence of this ingredient, confirming it to be not-fungal acne safe.

Cetearyl Olivate is a plant-derived emulsifier and texture enhancer. It helps keep the oil and water phases from separating so your formulas stay stable.

You'll likely see it combined with Sorbitan Olivate (together sold as the trade name Olivem 1000). This combination generates a liquid crystal structure that closely resemble the lipid organization of the stratum corneum.

These "skin-like" liquid crystals improve skin barrier integrity and promote the delivery of actives into the skin.

This ingredient is well-tolerated and has no significant sensitization data.

Because it is derived from the fatty acids in olive oil, this ingredient may not be fungal acne safe.

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.

Glyceryl Stearate is made by reacting glycerin with stearic acid (typically sourced from plant oils like palm or coconut). It's an emulsifier, emollient, and mild occlusive.

Emulsifiers help ingredients like oil and water stay mixed so your formula stays nicely blended and uniform in texture.

This ingredient is typically used in concentrations between 1-10%. Studies have found it to be non-sensitizing, non-phototoxic, and non-photoallergenic.

A close cousin of this ingredient is Glyceryl Stearate SE ("self-emulsifying"). This just has a small amount of sodium or potassium stearate added so it can emulsify without a co-emulsifier.

Since this ingredient is an ester of a C18 fatty acid, it may not be fungal acne safe. The Malassezia yeast can potentially metabolize within the C11-C24 range.

Fun fact: The human body also creates Glyceryl Stearate naturally.

Limnanthes Alba Seed Oil is from the seeds of the meadowfoam plant. It is a skin conditioning agent and emollient that sits on top of skin to soften and hydrate it.

Over 98% of the oil is made up of long-chain fatty acids, mostly aachidic acid (61%), docosenoic acid (~16%), and docosadienoic acid (~18%).

This combination is not really found in any other plant oil and is the reason this is one of the most stable botanical oils available.

Some studies show it to be more stable than jojoba oil, helps a product resist going rancid, and can help extend the shelf life of a formula.

It also naturally contains vitamin E and phytosterols that give it a mild antioxidant benefit.

This ingredient is typically used from around 1% to fairly high levels since it's gentle; it's well-tolerated and low on the irritation scale.

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.

Polyacrylate Crosspolymer-6 is a texture enhancer and pH adjuster.

It is be used to thicken water-based products and create a gel-texture with a velvet feel.

One manufacturer claims this ingredient to have a pH range of 2-8 and to be biodegradable.

This ingredient is also known as Sepimax Zen.

Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin.

It’s often used to:

Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

Jojoba oil is one of the most well-studied plant-derived ingredients in cosmetics. It is an emollient with a special structure.

Because it is made up of 97-98% wax esters, it closely mirrors the linear monoesters found in human sebum. This makes it skin compatible, non-greasy, and lightweight.

Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture.

Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%).

Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing.

Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.

Fungal acne: The Malassezia yeast is known to metabolize fatty acids in the C11-24 range and jojoba's dominant fatty acid components fall into this range. This ingredient may not be fungal acne safe.

Sorbitan Olivate is created from the fatty acids in olive oil and sorbitol.

This ingredient is an oil in water emulsifier. It helps stabilize a product by preventing oils and waters from separating. Sorbitan Olivate also helps hydrate the skin.

This ingredient is also known as part of Olivem 1000, with Cetearyl Olivate being the other part.

According to a manufacturer, this ingredient helps preserve the natural microbiome of skin. Having a healthy microbiome helps keep our skin healthy and protects against harmful bacteria.

Please note, having a healthy microbiome is different from fungal acne; a healthy microbiome includes small amounts of yeast that normally live on your skin without causing problems.

Fungal acne happens when one type of yeast (Malassezia) grows out of control. This is usually because it's feeding on certain oils or fatty acids. Due to the olive oil base, this ingredient may not be fungal acne safe.

Tocopherol is a fat-soluble antioxidant known as Vitamin E.

You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.

Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.

It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.

This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.

This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.

In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.

Concentrations usually range from 0.1-1% in most leave-on products.

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!

RESEARCH

Research Models and Methodology Behind the Claims

Understanding how the underlying studies were done is essential to weighting them, because the model determines what a result can and cannot mean. The GHK-Cu collagen literature rests heavily on cell-culture models: primary human dermal fibroblasts (or, in some studies, irradiated or aged fibroblasts) exposed to defined peptide concentrations, with readouts such as collagen and elastin protein, hydroxyproline content, MMP/TIMP gene and protein expression, and proliferation.3,4 The strength of this design is mechanistic control — you can isolate a concentration-response curve. Its limitation is that a monolayer of fibroblasts bathed in peptide is a radically simplified stand-in for intact, vascularized, immunologically active human skin. Effects that appear at 10-9 M in a dish may never be reproduced by an injected or topical dose in vivo, where absorption, distribution, protein binding, and clearance all intervene. The cosmetic clinical studies use a different methodology: human volunteers apply a topical GHK-Cu formulation, and outcomes are assessed by instrumental skin imaging (wrinkle volume/depth, skin density by ultrasound, elasticity) over weeks.4,13 These are genuine human data and closer to a real endpoint, but they carry their own caveats: small sample sizes, cosmetic (appearance) rather than histological (biopsy-confirmed collagen) endpoints in many cases, frequent industry sponsorship, formulation-specific results (a particular cream or nanocarrier, not the peptide in isolation), and short durations. A wrinkle-imaging improvement is a legitimate cosmetic outcome but a weak proxy for “enhanced collagen synthesis pathways” at the tissue level. The BPC-157 and TB-500 evidence leans even more heavily on animal models: rodent tendon, muscle, gut, and skin-wound experiments, plus ex-vivo tissue explants and cell-migration assays.5,8,9 Rodent wound-healing models are informative for hypothesis generation but notoriously over-optimistic as predictors of human efficacy; rodent skin heals differently from human skin (more contraction, looser attachment), and the injury contexts studied (acute surgical or chemical wounds) differ from the chronic, low-grade “aging” context that skin-collagen marketing invokes. The methodological distance between “Tβ4 accelerated closure of a full-thickness rat wound” and “an injected blend increases collagen in healthy adult human dermis” is very large. Two systematic methodological red flags recur across this field. First is publication and author concentration: much of the BPC-157 literature originates from a small number of research groups, and independent replication is limited — a pattern reviewers explicitly flag when cautioning against over-reading the animal data.9,10 Second is the gap between surrogate and clinical endpoints. Many “positive” findings are early surrogate markers — mRNA levels, phosphorylation states, histology scores — rather than the outcomes a person would notice. Surrogate markers frequently fail to translate into clinical benefit, and the history of dermatology and regenerative medicine is littered with in-vitro “collagen boosters” that did nothing measurable in controlled human trials. The methodological bottom line for Glow specifically is that the blend has never been the subject of any of these study types. There is no cell-culture study of the three peptides combined, no animal study of the blend, and no human study. So even the modest, model-limited evidence that exists for the parts cannot be assumed to carry over, because combination effects (synergy, antagonism, altered stability, competition for uptake or copper) are precisely the things that single-agent studies cannot capture. The methodology supporting Glow’s headline claim is, in the strictest sense, not the study of Glow at all.
