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.
Betaine salicylate is a gentle beta-hydroxy acid derivative that releases salicylic acid to exfoliate the skin surface and unclog pores. It is commonly used in lower-irritation formulations targeting acne, blackheads, and uneven texture.
Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products.
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 stinging | Uncommon | More likely on sensitive or compromised skin. |
| Contact dermatitis or allergic reaction | Rare | Possible in individuals sensitive to salicylates or plant tannins. |
| Cross-reactivity in salicylate- or aspirin-sensitive individuals | Rare | Due to naturally occurring salicin/salicylate content. |
| Mild skin irritation or redness | Rare | Possible in sensitive skin, generally transient. |
| Allergic contact dermatitis | Very rare | Reported in individuals sensitized to apple proteins or related botanicals. |
| Contact urticaria | Very rare | Linked to fruit-protein allergy, particularly in those with oral allergy syndrome. |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or at high concentrations. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Skin irritation (mild redness or stinging) | Uncommon | Generally well tolerated; transient irritation may occur, particularly at higher concentrations or on compromised skin. |
| Increased photosensitivity | Common | As an alpha-hydroxy acid derivative it can heighten sensitivity to UV; sunscreen use is advised. |
| Skin irritation, stinging or burning | Uncommon | More likely at higher concentrations or on compromised/sensitive skin. |
| Redness or dryness | Uncommon | Paradoxical irritation possible in some individuals despite its humectant role. |

| 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. |
| Salix Alba (Willow) Bark Water Astringent/conditioning agent | Salix Alba (Willow) Bark Water is the aqueous extract of white willow bark, naturally containing salicin and tannins, used in skincare for mild astringent, soothing, and conditioning effects. It is often included as a gentle, plant-derived alternative source of salicylate compounds. |
| Pyrus Malus (Apple) Fruit Water Hydrating/skin-conditioning aqueous solvent | Pyrus Malus (Apple) Fruit Water is the aqueous fraction obtained from apples, used in cosmetics as a water-based solvent and skin-conditioning agent that provides light hydration and trace fruit-derived components. It typically functions as part of the formulation base rather than as a treatment active. |
| 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. |
| 1,2-Hexanediol Humectant / preservative booster | 1,2-Hexanediol is a synthetic diol used in skincare as a humectant and solvent that also enhances the antimicrobial efficacy of formulations, often allowing reduced or preservative-free systems. It helps maintain product stability while contributing mild moisturizing properties. |
| Sodium Lactate Humectant / NMF component | Sodium lactate is the sodium salt of lactic acid and a key component of skin's natural moisturizing factor (NMF), used to hydrate the skin and buffer formulation pH. It also has mild exfoliating and humectant properties that help maintain skin moisture and barrier function. |
| 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. |
| Betaine Salicylate Key active Exfoliant / BHA | Betaine salicylate is a gentle beta-hydroxy acid derivative that releases salicylic acid to exfoliate the skin surface and unclog pores. It is commonly used in lower-irritation formulations targeting acne, blackheads, and uneven texture. |
| Allantoin Key active Soothing/skin-conditioning agent | Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products. |
| 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. |
| Ethyl Hexanediol Solvent/preservative booster | Ethylhexanediol (often listed as ethyl hexanediol or 2-ethyl-1,3-hexanediol) is a synthetic diol used in cosmetics primarily as a solvent, emollient, and to enhance the efficacy of preservative systems. It also has mild humectant and antimicrobial-boosting properties and is commonly found in lotions and serums. |
