Caffeine is a topical active used in skincare for its antioxidant properties and ability to constrict blood vessels, which may temporarily reduce puffiness and the appearance of under-eye darkness. It is also studied for reducing localized fluid retention and protecting against UV-induced oxidative stress.
Tocopheryl acetate is a stable, esterified form of vitamin E used in skincare as an antioxidant and conditioning agent. It is converted to active tocopherol in the skin, helping protect against oxidative stress and supporting the skin barrier.
Butyl Methoxydibenzoylmethane, also known as avobenzone, is a widely used organic sunscreen agent that absorbs UVA radiation. It is often combined with photostabilizers and other UV filters because it can degrade with sun exposure.
Ethylhexyl Methoxycinnamate (octinoxate) is a widely used organic UVB-absorbing sunscreen agent that protects skin from ultraviolet radiation. It is commonly incorporated into sunscreens and daily cosmetics with SPF claims.
Ethylhexyl Salicylate (octisalate) is an oil-soluble organic UVB filter used in sunscreens to absorb ultraviolet radiation in the 295-315 nm range. It is also valued as a solvent that helps stabilize and dissolve other UV filters in formulations.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| 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. |
| Allergic contact dermatitis | Uncommon | Reported as a contact sensitizer, particularly in patients with leg ulcers or stasis dermatitis; included in some patch-test series. |
| Skin irritation | Rare | Mild irritation or redness possible, generally in sensitive or compromised skin. |
| Cross-reactivity with other fatty alcohols | Rare | Individuals sensitized to cetyl or stearyl alcohol may react to the blend. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Acne/comedogenicity | Rare | Heavy emollient esters may contribute to clogged pores in acne-prone skin. |
| Comedogenicity (clogged pores, acne flare) | Common | Considered moderately comedogenic; may worsen acne in acne-prone individuals. |
| Skin irritation or mild stinging | Uncommon | Occasional irritation, particularly on sensitive or compromised skin. |
| Folliculitis | Rare | Occlusive nature can occasionally promote follicular inflammation. |
| Contact dermatitis (irritant or allergic) | Rare | Reported in patch-test and occupational settings; PEG/ceteareth emulsifiers are recognized sensitizers in some individuals. |
| Enhanced penetration of other ingredients | Uncommon | As a surfactant it may increase skin permeability, indirectly affecting tolerance of co-formulated actives. |
| Concern over ethylene oxide/1,4-dioxane impurities | Very rare | Trace process contaminants are possible; purification and regulatory limits minimize this risk. |

| Ingredient | What it does |
|---|---|
| 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. |
| Cetearyl Alcohol Emollient/emulsifier | Cetearyl alcohol is a fatty alcohol blend (cetyl and stearyl alcohol) used in skincare as an emollient, emulsion stabilizer, and thickening agent. It helps soften skin and keep oil and water phases blended in creams and lotions. |
| 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. |
| Di-C12-13 Alkyl Malate Emollient / skin-conditioning agent | Di-C12-13 Alkyl Malate is an ester of malic acid and fatty alcohols used as an emollient and texture enhancer in cosmetics. It imparts a smooth, conditioning feel and acts as a binder and dispersing agent, commonly in lip and color products. |
| Isopropyl Palmitate Emollient / Thickener | Isopropyl Palmitate is an ester of isopropyl alcohol and palmitic acid used as an emollient, skin-conditioning agent, and texture enhancer that improves spreadability and reduces greasiness in creams, lotions, and cosmetics. It is a formulation/base ingredient rather than a therapeutic active. |
| Ceteareth-20 Emulsifier/surfactant | Ceteareth-20 is a polyethylene glycol (PEG) ether of cetearyl alcohol used primarily as a nonionic emulsifier and surfactant to stabilize oil-in-water formulations. It is a formulation base ingredient rather than a treatment active. |
| Phenoxyethanol Preservative | Phenoxyethanol is a widely used broad-spectrum preservative that protects cosmetic and skincare formulations from bacterial and fungal contamination. It is typically used at concentrations up to 1% and serves as a formulation/base ingredient rather than an active treatment. |
| Fragrance/Parfum Fragrance/sensory additive | Fragrance (parfum) is a blend of natural or synthetic aromatic compounds added to cosmetic and skincare products to impart scent or mask the base odor of other ingredients. It provides no therapeutic skin benefit and is included purely for sensory or marketing purposes. |
| Caffeine Key active Antioxidant / vasoconstrictor | Caffeine is a topical active used in skincare for its antioxidant properties and ability to constrict blood vessels, which may temporarily reduce puffiness and the appearance of under-eye darkness. It is also studied for reducing localized fluid retention and protecting against UV-induced oxidative stress. |
| Caprylyl Glycol Humectant / skin-conditioning agent and preservative booster | Caprylyl glycol is a multifunctional emollient and humectant derived from caprylic acid that helps hydrate skin and enhance the efficacy of preservatives in formulations. It is widely used as a stabilizing and conditioning base ingredient rather than a therapeutic active. |
| Tocopheryl Acetate Key active Antioxidant | Tocopheryl acetate is a stable, esterified form of vitamin E used in skincare as an antioxidant and conditioning agent. It is converted to active tocopherol in the skin, helping protect against oxidative stress and supporting the skin barrier. |
| 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. |
| Triethanolamine pH adjuster / emulsifier | Triethanolamine is an organic compound used in cosmetic formulations primarily to adjust pH and to act as an emulsifying agent, helping to stabilize mixtures of oil and water. It is typically present in small concentrations as a formulation aid rather than a therapeutic active. |
| Bht Antioxidant/preservative | BHT (butylated hydroxytoluene) is a synthetic phenolic antioxidant used in small amounts to prevent oxidation and rancidity of oils, fragrances, and other unstable components, helping maintain product stability and shelf life. |
| Butyl Methoxydibenzoylmethane Key active UV filter (UVA sunscreen) | Butyl Methoxydibenzoylmethane, also known as avobenzone, is a widely used organic sunscreen agent that absorbs UVA radiation. It is often combined with photostabilizers and other UV filters because it can degrade with sun exposure. |
