Glycolic acid is an alpha-hydroxy acid derived from sugar cane that exfoliates by loosening bonds between dead skin cells on the surface, promoting cell turnover and improving texture, tone, and fine lines. It is one of the smallest AHAs, allowing relatively deep penetration into the skin.
Lactic acid is an alpha-hydroxy acid that exfoliates the skin by loosening bonds between corneocytes, promoting cell turnover, and acting as a humectant to improve hydration, texture, and tone. It is commonly used at concentrations ranging from low (hydration) to higher peel-strength formulations.
Gluconolactone (glucono delta-lactone) is a polyhydroxy acid (PHA) that gently exfoliates, hydrates, and provides antioxidant and mild moisturizing benefits. It is considered gentler than traditional alpha-hydroxy acids, making it suitable for sensitive skin.
Mandelic acid is an alpha-hydroxy acid derived from bitter almonds with a relatively large molecular size, allowing slower, gentler skin penetration. It is used to exfoliate, improve skin texture and tone, address hyperpigmentation, and manage acne.
Tocopherol (vitamin E) is a lipid-soluble antioxidant used in skincare to protect skin and formulations from oxidative damage caused by free radicals and UV exposure. It also functions as a skin-conditioning and emollient agent and can stabilize oils against rancidity.

Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Irritation or sensitivity | Very rare | Purified water itself is essentially inert; rare reactions are attributable to contaminants or accompanying ingredients rather than water. |
| Transepidermal water loss aggravation in compromised skin | Rare | Evaporation of water from products may transiently increase dryness in very compromised skin barriers if occlusives are absent. |
| Mild skin irritation or stinging | Common | More likely at higher concentrations or on compromised/sensitive skin |
| Allergic contact dermatitis | Uncommon | Recognized contact allergen; confirmed via patch testing |
| Irritant contact dermatitis | Uncommon | Non-allergic irritation, often dose-dependent |
| Worsening of pre-existing eczema or barrier-impaired skin | Rare | Penetration-enhancing effect may increase reactivity |
| Systemic toxicity from topical use | Very rare | Reported mainly with extensive application on broken skin, especially in infants or burn patients |
| Skin irritation, stinging, or burning sensation | Common | Often dose- and concentration-dependent, especially at low pH or high percentages. |
| Redness (erythema) | Common | Usually transient and resolves after application or with reduced frequency. |
| Dryness and peeling | Common | Result of increased exfoliation; mitigated by moisturizer use. |
| Increased photosensitivity (sun sensitivity) | Common | AHAs reduce stratum corneum thickness; daily sunscreen is advised. |
| Post-inflammatory hyperpigmentation | Uncommon | More likely in darker skin tones or with overuse/irritation. |
| Contact dermatitis or allergic reaction | Rare | Genuine allergy is uncommon; most reactions are irritant rather than allergic. |
| Chemical burns or blistering | Rare | Typically associated with high concentrations, low pH, or prolonged contact in peels. |
| Scarring | Very rare | Reported with improper high-strength peel application or severe burns. |

| Ingredient | What it does |
|---|---|
| Aqua Solvent / vehicle | Aqua (water) is the most common base ingredient in skincare formulations, serving as a solvent that dissolves water-soluble components and forms the medium for emulsions. It has no direct treatment activity and primarily contributes to texture, spreadability, and product delivery. |
| Propylene glycol Humectant / solvent | Propylene glycol is a small glycol molecule widely used in skincare as a humectant, solvent, and penetration enhancer that helps attract water and dissolve other ingredients. It is considered a base/formulation ingredient rather than a therapeutic active. |
| Glycolic acid Key active Chemical exfoliant (AHA) | Glycolic acid is an alpha-hydroxy acid derived from sugar cane that exfoliates by loosening bonds between dead skin cells on the surface, promoting cell turnover and improving texture, tone, and fine lines. It is one of the smallest AHAs, allowing relatively deep penetration into 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. |
| Lactic acid Key active Chemical exfoliant (AHA) | Lactic acid is an alpha-hydroxy acid that exfoliates the skin by loosening bonds between corneocytes, promoting cell turnover, and acting as a humectant to improve hydration, texture, and tone. It is commonly used at concentrations ranging from low (hydration) to higher peel-strength formulations. |
| Glucocnodeltalactone Key active Exfoliant / humectant (polyhydroxy acid) | Gluconolactone (glucono delta-lactone) is a polyhydroxy acid (PHA) that gently exfoliates, hydrates, and provides antioxidant and mild moisturizing benefits. It is considered gentler than traditional alpha-hydroxy acids, making it suitable for sensitive skin. |
| Octyldodecanol Emollient/solvent | Octyldodecanol is a branched fatty alcohol used in cosmetic formulations as an emollient, solvent, and skin-conditioning agent that improves spreadability and texture. It helps soften skin and dissolve other ingredients without functioning as a treatment active. |
| Octyldodecyl Xyloside Emollient / emulsifier | Octyldodecyl Xyloside is a sugar-derived (xylose) emollient and co-emulsifier used in skincare to condition skin and stabilize emulsions. It is typically part of a blend that supports the skin barrier and improves texture and spreadability. |
| PEG-30 Dipolyhydroxystearate Emulsifier | PEG-30 Dipolyhydroxystearate is a polyethylene glycol-based emulsifier used to stabilize water-in-oil emulsions in creams, sunscreens, and lotions. It functions as a formulation/base ingredient rather than a treatment active. |
| Mandelic acid Key active Chemical exfoliant (AHA) | Mandelic acid is an alpha-hydroxy acid derived from bitter almonds with a relatively large molecular size, allowing slower, gentler skin penetration. It is used to exfoliate, improve skin texture and tone, address hyperpigmentation, and manage acne. |
| Polyacrylate-13 Rheology modifier / thickener | Polyacrylate-13 is a synthetic acrylate copolymer used as a thickening, stabilizing, and emulsifying agent in cosmetic formulations. It helps create stable gels and emulsions and improves product texture without contributing to active treatment effects. |
| Polyisobutene Emollient/film-former | Polyisobutene is a synthetic hydrocarbon polymer used in cosmetics as an emollient, thickener, and film-forming agent that imparts smooth texture, adhesion, and improved spreadability. It is commonly found in long-wear makeup, lip products, and sunscreens to enhance water resistance and product longevity. |
| 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.
