Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
Palmitoyl Tripeptide-1 is a synthetic palmitoylated peptide (sequence Gly-His-Lys) used in cosmetics to signal fibroblasts and support collagen and extracellular matrix synthesis. It is commonly combined with other peptides in anti-aging and firming formulations.
Palmitoyl Tetrapeptide-7 is a palmitoylated synthetic peptide used in cosmetic formulations, primarily marketed to help reduce inflammatory signaling and support a more even, firmer skin appearance. It is commonly paired with other peptides such as Palmitoyl Tripeptide-1 in anti-aging products.
Pichia/Resveratrol Ferment Extract is a biofermentation-derived ingredient produced by fermenting resveratrol with Pichia yeast, valued for its antioxidant and skin-conditioning properties. It is used in topical formulations to help neutralize free radicals and support a more even, radiant skin appearance.
Rhodiola rosea root extract is a botanical derived from the arctic root plant, valued in skincare for its antioxidant and anti-stress (adaptogenic) properties attributed to compounds like salidroside and rosavin. It is used to help protect skin from oxidative stress and environmental damage.
Rhus coriaria (sumac) leaf/stem extract is a plant-derived ingredient rich in polyphenols, tannins, and flavonoids used in skincare for its antioxidant and astringent properties. It may help support skin tone and provide protection against oxidative stress.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Mild transient flushing or redness | Uncommon | More likely at higher concentrations or in sensitive skin; usually subsides quickly. |
| Tingling, stinging, or burning sensation | Uncommon | Often associated with higher percentages or compromised barrier. |
| Contact irritation or itching | Rare | Generally dose-dependent and resolves with discontinuation. |
| Allergic contact dermatitis | Very rare | Documented in isolated case reports; true sensitization is unusual. |
| Mild transient skin irritation or redness | Uncommon | Generally mild and resolves after discontinuation; often related to formulation rather than the peptide itself. |
| Contact dermatitis or allergic sensitization | Rare | Isolated reports; patch testing may be warranted in sensitive individuals. |
| Stinging or tingling on application | Rare | Usually temporary and associated with compromised skin barrier. |
| Mild transient irritation or redness | Rare | Generally well tolerated; localized irritation may occur, often related to other formulation components. |
| Contact sensitization or allergic dermatitis | Very rare | Isolated reports; peptides are considered low-allergenicity but sensitization remains possible. |
| Stinging on application | Rare | Usually mild and short-lived, more likely on compromised or sensitive skin. |
| Mild skin irritation | Uncommon | Generally well tolerated; transient irritation possible, more likely in sensitive or compromised skin. |
| Eye irritation | Uncommon | Surfactant properties can cause stinging or irritation on direct ocular contact. |
| Enhanced penetration of other ingredients | Common | Not an adverse effect per se, but as a solubilizer it may increase absorption of co-formulated substances. |

| Ingredient | What it does |
|---|---|
| Water Solvent/vehicle | Water is the most common base ingredient in cosmetic formulations, serving as a solvent that dissolves other ingredients and forms the bulk of emulsions and aqueous solutions. It is generally considered safe and non-irritating. |
| Niacinamide Key active Cell-communicating / barrier-repair active | Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%. |
| Palmitoyl Tripeptide-1 Key active Signal peptide / anti-aging active | Palmitoyl Tripeptide-1 is a synthetic palmitoylated peptide (sequence Gly-His-Lys) used in cosmetics to signal fibroblasts and support collagen and extracellular matrix synthesis. It is commonly combined with other peptides in anti-aging and firming formulations. |
| Palmitoyl Tetrapeptide-7 Key active Anti-aging signal peptide | Palmitoyl Tetrapeptide-7 is a palmitoylated synthetic peptide used in cosmetic formulations, primarily marketed to help reduce inflammatory signaling and support a more even, firmer skin appearance. It is commonly paired with other peptides such as Palmitoyl Tripeptide-1 in anti-aging products. |
| Polysorbate 20 Emulsifier / solubilizer | Polysorbate 20 is a nonionic surfactant derived from sorbitol and lauric acid, used in skincare to solubilize fragrances and essential oils and to stabilize oil-in-water emulsions. It functions primarily as a formulation aid rather than a treatment active. |
| Glycerin Humectant | Glycerin is a widely used humectant that attracts and retains water in the skin, helping to hydrate the stratum corneum and support barrier function. It is considered safe and well-tolerated across most skin types and concentrations. |
| Butylene Glycol Humectant / solvent | Butylene glycol is a small diol commonly used in skincare as a humectant, solvent, and viscosity-reducing agent that helps dissolve other ingredients and improve skin feel. It is widely regarded as safe and non-sensitizing for the majority of users at cosmetic concentrations. |
| Carbomer Thickener / gelling agent | Carbomer is a synthetic high-molecular-weight polymer of acrylic acid used to thicken, stabilize, and control the viscosity of gels, creams, and lotions. It functions as a formulation aid rather than a therapeutic active. |
| Betaine Humectant / osmolyte | Betaine is a naturally derived amino acid derivative (trimethylglycine) used in skincare as a humectant and osmoprotectant that attracts and retains moisture while helping stabilize skin barrier function. It also improves the texture and mildness of formulations. |
| Propanediol Humectant/solvent | Propanediol is a plant-derived glycol used in skincare as a humectant, solvent, and penetration enhancer that improves moisturization and the spreadability of formulations. It also helps solubilize other ingredients and can boost the efficacy of certain actives. |
| Pichia/Resveratrol Ferment Extract Key active Antioxidant / skin-conditioning | Pichia/Resveratrol Ferment Extract is a biofermentation-derived ingredient produced by fermenting resveratrol with Pichia yeast, valued for its antioxidant and skin-conditioning properties. It is used in topical formulations to help neutralize free radicals and support a more even, radiant skin appearance. |
| Rhodiola Rosea Root Extract Key active Antioxidant / adaptogen botanical extract | Rhodiola rosea root extract is a botanical derived from the arctic root plant, valued in skincare for its antioxidant and anti-stress (adaptogenic) properties attributed to compounds like salidroside and rosavin. It is used to help protect skin from oxidative stress and environmental damage. |
| Rhus Coriaria Leaf/Stem Extract Key active Antioxidant / astringent | Rhus coriaria (sumac) leaf/stem extract is a plant-derived ingredient rich in polyphenols, tannins, and flavonoids used in skincare for its antioxidant and astringent properties. It may help support skin tone and provide protection against oxidative stress. |
