Retinol is a vitamin A derivative that converts to retinoic acid in the skin, promoting cell turnover and stimulating collagen synthesis. At 0.5% it is a moderate-strength over-the-counter active used for anti-aging, texture refinement, and acne support.
Tocotrienols are a subgroup of vitamin E compounds used in skincare for their antioxidant activity, helping protect skin lipids from oxidative damage caused by UV exposure and environmental stressors. They are often combined with tocopherols and other antioxidants to enhance stability and skin protection.
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.
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 skin irritation or stinging | Uncommon | Usually transient and more likely on compromised or sensitive skin. |
| Allergic contact dermatitis | Rare | Sensitization to soy proteins or oil components has been documented but is infrequent. |
| Comedogenicity / acne aggravation | Uncommon | Has a low-to-moderate comedogenic potential in acne-prone individuals. |
| Contact urticaria in soy-allergic individuals | Very rare | Refined oil contains minimal protein, so reactions are exceptional but theoretically possible in highly sensitized people. |
| Skin irritation | Rare | Mild transient irritation possible in sensitive individuals. |
| Acne/comedogenicity | Rare | Heavy emollient esters may contribute to clogged pores in acne-prone skin. |
| Dryness and flaking (retinoid dermatitis) | Common | Especially during the initial weeks of use as skin acclimates. |
| Erythema (redness) | Common | Often accompanies early irritation and the adjustment period. |
| Stinging or burning sensation | Common | Transient, typically on application to compromised or sensitive skin. |
| Increased photosensitivity | Common | Heightened sun sensitivity; daily sunscreen is recommended. |
| Peeling and skin purging | Uncommon | Temporary breakout or shedding as cell turnover accelerates. |
| Contact dermatitis or significant irritation | Uncommon | May occur with overuse or in highly sensitive individuals. |
| Allergic sensitization | Rare | True allergic reaction to retinol or formulation components. |
| Hyperpigmentation following irritation | Rare | Post-inflammatory pigmentation, more likely in darker skin tones. |

| Glycine Soja (Soybean) Oil Emollient / antioxidant | Glycine Soja (Soybean) Oil is a plant-derived oil rich in linoleic acid, tocopherols, and phytosterols used in skincare to soften skin, reinforce the barrier, and provide mild antioxidant activity. It functions primarily as a base emollient rather than a targeted treatment active. |
| 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. |
| Retinol(0.5%) Key active Retinoid (vitamin A derivative) | Retinol is a vitamin A derivative that converts to retinoic acid in the skin, promoting cell turnover and stimulating collagen synthesis. At 0.5% it is a moderate-strength over-the-counter active used for anti-aging, texture refinement, and acne support. |
| 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. |
| 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. |
| Tocotrienols Key active Antioxidant | Tocotrienols are a subgroup of vitamin E compounds used in skincare for their antioxidant activity, helping protect skin lipids from oxidative damage caused by UV exposure and environmental stressors. They are often combined with tocopherols and other antioxidants to enhance stability and skin protection. |
| Tocopherol Key active Antioxidant | 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. |
| Elaeis Guineensis (Palm) Oil Emollient / skin-conditioning agent | Elaeis Guineensis (Palm) Oil is a plant-derived oil rich in fatty acids (palmitic and oleic) and tocopherols/tocotrienols, used in skincare to soften skin and provide an occlusive, emollient effect. It also serves as a base for soaps and a source of vitamin E. |
| 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. |
