Retinyl Propionate is an ester of vitamin A (retinol) that is converted in the skin to retinoic acid, supporting cell turnover and collagen production. It is considered a milder, more stable retinoid used to improve signs of photoaging.
Titanium dioxide is an inorganic mineral compound used primarily as a physical (mineral) sunscreen agent that reflects and scatters UV radiation, and also serves as a white pigment and opacifier in cosmetic formulations. It is broadly photostable and considered gentle, making it common in products for sensitive and pediatric skin.
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%.
Retinol is a vitamin A derivative that converts to retinoic acid in the skin, promoting cell turnover and stimulating collagen synthesis. It is widely used to address fine lines, photoaging, and acne.
Palmitoyl Pentapeptide-4 (Matrixyl, pal-KTTKS) is a lipidated peptide that signals fibroblasts to increase production of collagen, elastin, and other extracellular matrix components. It is used in topical formulations to help reduce the appearance of fine lines and improve skin firmness.
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 skin irritation or redness | Rare | Generally considered non-irritating; occasional mild reactions reported. |
| Clogged pores / comedogenic-related breakouts | Uncommon | Often anecdotal; dimethicone is largely regarded as non-comedogenic but may trap debris if skin is not cleansed well. |
| Allergic contact dermatitis | Very rare | True silicone allergy is exceptionally uncommon. |
| Eye irritation on accidental contact | Rare | Transient stinging or discomfort if product enters the eyes. |
| Mild transient stinging or irritation | Uncommon | More likely at high concentrations or on compromised/broken skin. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| Contact dermatitis or allergic reaction | Rare | True allergy to glycerin is uncommon; patch-test positivity is infrequent. |
| Skin dehydration in very low humidity | Rare | In very dry environments humectants may draw water from deeper skin layers if not paired with an occlusive. |
| Mild skin irritation | Rare | Occasional transient redness or irritation, typically in sensitive skin. |
| Pore congestion in oily/acne-prone skin | Uncommon | Powders may contribute to clogged pores in some individuals when heavily applied. |
| Mild irritation or sensitivity | Rare | Generally considered non-irritating; occasional reactions in highly sensitive individuals. |
| Acneiform breakouts/clogged pores | Rare | Silicones are largely non-comedogenic, but rare clogging reports exist, often linked to overall formulation or inadequate cleansing. |

| 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. |
| Dimethicone Emollient/occlusive (silicone) | Dimethicone is a silicone-based polymer used in skincare to soften skin, smooth texture, and form a breathable protective barrier that reduces transepidermal water loss. It is widely used as a base/formulation ingredient rather than a therapeutic 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. |
| Tapioca Starch Absorbent / texture enhancer | Tapioca starch is a plant-derived polysaccharide powder used in cosmetics to absorb excess oil and moisture, impart a soft matte finish, and improve the sensory texture of formulations. It functions as a base/formulation ingredient rather than a therapeutic active. |
| Dimethicone Crosspolymer Silicone-based texture enhancer/film former | Dimethicone Crosspolymer is a crosslinked silicone polymer used in skincare and cosmetics to provide a smooth, silky feel, absorb excess oil, blur the appearance of pores and fine lines, and improve product spreadability. It functions as a formulation ingredient rather than a therapeutic active. |
| Polyacrylamide Thickener/film-former | Polyacrylamide is a synthetic polymer used in cosmetics primarily as a thickening agent, film former, and stabilizer that improves texture and viscosity of formulations. It is considered a base/formulation ingredient rather than a treatment active. |
| C13-14 Isoparaffin Emollient/thickener | C13-14 Isoparaffin is a synthetic hydrocarbon used in skincare primarily as an emollient and as a thickening or gelling agent, often paired with polyacrylamide-based systems to stabilize emulsions. It helps improve spreadability and texture but provides no active treatment benefit. |
| Retinyl Propionate Key active Retinoid (anti-aging active) | Retinyl Propionate is an ester of vitamin A (retinol) that is converted in the skin to retinoic acid, supporting cell turnover and collagen production. It is considered a milder, more stable retinoid used to improve signs of photoaging. |
| DMDM Hydantoin Preservative (antimicrobial, formaldehyde-releaser) | DMDM Hydantoin is a formaldehyde-releasing preservative used in cosmetics and personal care products to prevent microbial growth and extend shelf life. It works by slowly releasing small amounts of formaldehyde into the formulation. |
| Laureth-4 Surfactant/emulsifier | Laureth-4 is a polyethylene glycol ether of lauryl alcohol used as a nonionic surfactant, emulsifier, and solubilizer in cosmetic and topical formulations. It helps blend oil and water phases and improve product texture. |
