Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin.
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.
Carnosine is a naturally occurring dipeptide (beta-alanine and L-histidine) used in skincare for its antioxidant and anti-glycation properties, helping protect against oxidative stress and protein cross-linking associated with skin aging. It is typically incorporated into serums and creams at low concentrations as a supporting active.
Ascorbic acid (vitamin C) is a water-soluble antioxidant used in skincare to neutralize free radicals, inhibit melanin synthesis, and support collagen production. It is valued for brightening, evening skin tone, and protecting against photodamage when used alongside sunscreen.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Rare | Occasional transient redness or stinging, typically in sensitive skin or at high concentrations. |
| Contact dermatitis/allergic sensitization | Very rare | Isolated reports; PPG ethers are generally considered low-sensitizing. |
| Comedogenicity (pore clogging) | Rare | Possible in acne-prone skin given its emollient nature, though not strongly established. |
| 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. |
| Skin irritation | Rare | Mild irritation possible in sensitive individuals, generally low risk. |
| Allergic contact dermatitis | Very rare | Uncommon sensitization reported; considered low allergenic potential. |
| Mild skin or eye irritation | Uncommon | Generally low irritation potential; transient stinging or redness possible, more likely in leave-on or high-concentration use. |
| Dryness with frequent use | Uncommon | Repeated washing may disrupt skin barrier, though milder than anionic surfactants like SLS. |
| Skin dryness and peeling | Common | Mild flaking or tightness, especially with frequent use or higher concentrations. |
| Stinging, burning, or irritation | Common | Transient sensation on application, often more pronounced on sensitive or compromised skin. |
| Erythema (redness) | Common | Temporary redness at the application site. |
| Contact dermatitis | Uncommon | Localized inflammation; can be irritant or, less often, allergic in nature. |
| Increased photosensitivity | Uncommon | Exfoliation may heighten sun sensitivity; sunscreen use is advised. |
| Salicylism (systemic toxicity) | Rare | Reported with extensive application over large body areas, high concentrations, or occlusion; symptoms include nausea, tinnitus, and dizziness. |
| Severe allergic reaction | Very rare | Hypersensitivity reactions such as significant swelling or hives. |

| Ingredient | What it does |
|---|---|
| Ppg-15 Stearyl Ether Emollient/Skin-conditioning | PPG-15 Stearyl Ether is a polypropylene glycol ether of stearyl alcohol used as an emollient and skin-conditioning agent in cosmetic formulations. It imparts a smooth, conditioning feel and helps spread oils and other ingredients across the skin. |
| 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. |
| Oxidized Polyethylene Texture enhancer / viscosity agent | Oxidized polyethylene is a synthetic polymer derived from oxidizing polyethylene wax, used in skincare and cosmetics primarily as a thickening, stabilizing, and texture-modifying agent. It helps improve product consistency, opacity, and the application feel of creams, sticks, and color cosmetics. |
| Stearyl Alcohol Emollient/emulsifier | Stearyl alcohol is a fatty alcohol used in skincare as an emollient, emulsion stabilizer, and thickening agent to improve texture and prevent ingredient separation. It softens skin and helps maintain the consistency of creams and lotions. |
| Cetyl Betaine Surfactant/cleansing agent | Cetyl Betaine is an amphoteric (zwitterionic) surfactant derived from coconut or fatty acids, used in cleansers and shampoos to provide mild foaming, cleansing, and viscosity-enhancing properties. It is often combined with other surfactants to reduce overall irritation potential. |
| Salicylic Acid Key active Beta-hydroxy acid (BHA) exfoliant / keratolytic | Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin. |
| Distearyldimonium Chloride Antistatic/conditioning agent | Distearyldimonium Chloride is a quaternary ammonium compound used in skincare and haircare formulations as a conditioning, antistatic, and emulsifying agent. It helps improve product texture and substantivity on skin and hair. |
| Sodium Lauryl Sulfate Surfactant / cleansing agent | Sodium Lauryl Sulfate (SLS) is an anionic surfactant widely used in cleansers, shampoos, and toothpastes to remove oil and debris and to produce foam. It is also used in patch testing as a standard skin irritant. |
| Cetyl Alcohol Emollient / emulsifier | Cetyl alcohol is a fatty alcohol used in skincare and cosmetics as an emollient, thickener, and emulsion stabilizer. It softens skin and helps maintain the consistency and texture of creams and lotions. |
| Alcohol Solvent / penetration enhancer | Alcohol (typically ethanol or denatured alcohol) is used in skincare as a solvent, antimicrobial agent, and to improve product spreadability and rapid drying. It also enhances penetration of other ingredients and gives a lightweight feel to formulations. |
| Steareth-21 Emulsifier/surfactant | Steareth-21 is a polyethylene glycol ether of stearyl alcohol used as a nonionic emulsifier and surfactant to stabilize oil-in-water emulsions and improve texture in skincare formulations. It is a base/formulation ingredient rather than a treatment active. |
| Behenyl Alcohol Emollient / Thickener | Behenyl alcohol is a fatty alcohol derived from behenic acid that functions as an emollient, thickening agent, and emulsion stabilizer in cosmetic and skincare formulations. It helps soften the skin and improve product texture and stability. |
| Ppg-30 Emollient/humectant | PPG-30 (a polypropylene glycol with an average of 30 propylene oxide units) is a synthetic polyether used in cosmetic formulations as a skin-conditioning agent, emollient, and solvent. It helps soften skin and aids in dispersing or solubilizing other ingredients. |
| Steareth-2 Emulsifier / surfactant | Steareth-2 is a polyethylene glycol ether of stearyl alcohol used as a nonionic emulsifier and surfactant to blend oil and water phases in creams and lotions. It functions as a formulation/base ingredient rather than an active treatment. |
| Fragrance Fragrance/masking agent | Fragrance refers to a blend of natural or synthetic aromatic compounds added to skincare products to impart a pleasant scent or mask the odor of other ingredients. It serves a sensory and formulation purpose rather than a therapeutic one. |
| Panthenol Humectant / skin-conditioning agent | Panthenol (provitamin B5) is converted to pantothenic acid in the skin, where it acts as a humectant and helps support skin barrier function and hydration. It is also used for its soothing and mild anti-inflammatory properties in topical formulations. |
