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.
Solanum Lycopersicum (Tomato) Fruit Extract is a plant-derived ingredient rich in carotenoids (notably lycopene), vitamins, and polyphenols, used in skincare for its antioxidant and skin-conditioning properties. It is thought to help neutralize free radicals and support skin tone, though clinical evidence in topical formulations is limited.
Rosmarinus Officinalis (Rosemary) Leaf Extract is a plant-derived ingredient rich in polyphenols such as rosmarinic acid and carnosic acid, used in skincare for its antioxidant, anti-inflammatory, and antimicrobial properties. It is commonly added to help protect formulations and skin from oxidative stress.
Hydroxymethoxyphenyl Decanone (sold as Sytenol A) is a synthetic compound used in skincare for its soothing and antioxidant properties, often paired with bakuchiol-type formulations. It helps calm irritation and supports the skin barrier.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Mild irritation or stinging | Rare | Generally only with impure formulations or already compromised skin. |
| Allergic contact dermatitis | Very rare | Isolated case reports; squalane has very low sensitizing potential. |
| Acneiform breakouts / clogged pores | Rare | Low comedogenic rating, but acne-prone individuals may occasionally react. |
| Mild contact irritation | Rare | Occasional redness or stinging, usually in sensitive or compromised skin. |
| Comedogenicity / clogged pores | Rare | Generally low comedogenic potential, but acne-prone individuals may occasionally react. |
| Skin irritation or redness | Rare | Generally well tolerated; mild irritation occasionally reported. |
| Acneiform breakouts / comedones | Very rare | Considered low on the comedogenic scale, but individual clogging responses are possible. |
| Contact urticaria | Very rare | Very few reported cases of immediate hypersensitivity reactions. |
| Dryness and flaking | Common | Often occurs during the initial adjustment period as skin acclimates. |
| Erythema (redness) | Common | Mild irritation and redness, especially at higher concentrations. |
| Stinging or burning sensation | Common | Typically transient upon application. |
| Increased photosensitivity | Common | Skin becomes more susceptible to UV damage; daytime sunscreen recommended. |
| Peeling or scaling | Uncommon | More likely with frequent use or higher strengths. |
| Retinoid dermatitis | Uncommon | Contact dermatitis-like reaction with persistent irritation. |
| Purging (temporary breakouts) | Uncommon | Transient acne flare attributed to accelerated cell turnover. |
| Severe allergic contact dermatitis | Rare | Hypersensitivity reaction requiring discontinuation. |
| Hyperpigmentation or hypopigmentation | Rare | More frequently reported in darker skin tones following irritation. |

| Ingredient | What it does |
|---|---|
| Squalane Emollient / occlusive moisturizer | Squalane is a saturated, stable hydrocarbon derived from squalene (sourced from plants like olives or sugarcane, or shark liver) used as a lightweight emollient that softens skin and reinforces the skin barrier by reducing transepidermal water loss. It is well tolerated, non-comedogenic for most users, and serves as a base or carrier ingredient rather than a therapeutic active. |
| Caprylic/Capric Triglyceride Emollient / skin-conditioning agent | Caprylic/Capric Triglyceride is a lightweight emollient derived from coconut or palm oil and glycerin, used to soften skin, improve spreadability, and act as a solvent for oil-soluble ingredients. It is well-tolerated and serves primarily as a base ingredient rather than an active. |
| Simmondsia Chinensis (Jojoba) Seed Oil Emollient / moisturizer | Jojoba seed oil is a liquid wax ester derived from the seeds of Simmondsia chinensis, valued for its skin-compatible composition resembling human sebum. It functions primarily as an emollient and occlusive agent to soften skin and reduce transepidermal water loss. |
| Retinol Key active Vitamin A derivative / anti-aging active | 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. |
| Solanum Lycopersicum (Tomato) Fruit Extract Key active Antioxidant / skin-conditioning | Solanum Lycopersicum (Tomato) Fruit Extract is a plant-derived ingredient rich in carotenoids (notably lycopene), vitamins, and polyphenols, used in skincare for its antioxidant and skin-conditioning properties. It is thought to help neutralize free radicals and support skin tone, though clinical evidence in topical formulations is limited. |
| Rosmarinus Officinalis (Rosemary) Leaf Extract Key active Antioxidant / botanical extract | Rosmarinus Officinalis (Rosemary) Leaf Extract is a plant-derived ingredient rich in polyphenols such as rosmarinic acid and carnosic acid, used in skincare for its antioxidant, anti-inflammatory, and antimicrobial properties. It is commonly added to help protect formulations and skin from oxidative stress. |
| Hydroxymethoxyphenyl Decanone Key active Soothing/anti-irritant | Hydroxymethoxyphenyl Decanone (sold as Sytenol A) is a synthetic compound used in skincare for its soothing and antioxidant properties, often paired with bakuchiol-type formulations. It helps calm irritation and supports the skin barrier. |
| 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. |
