Caffeine anhydrous is a water-soluble methylxanthine used in topical skincare for its antioxidant properties and ability to temporarily constrict blood vessels, often included in eye and anti-cellulite formulations to reduce the appearance of puffiness and improve skin tone. It may also offer some protection against UV-induced oxidative damage.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
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.
Ribes Nigrum (blackcurrant) bud extract is a polyphenol- and flavonoid-rich botanical used in skincare for its antioxidant and skin-soothing properties. It is valued for potential anti-inflammatory effects and protection against environmental oxidative stress.
Alpha arbutin is a naturally derived hydroquinone derivative that inhibits tyrosinase, reducing melanin production. It is used to address hyperpigmentation, dark spots, and uneven skin tone.
Dunaliella Salina Extract is derived from a halophilic green microalga rich in carotenoids (notably beta-carotene), and is used in skincare for its antioxidant and skin-conditioning properties. It is thought to help protect against oxidative stress and support skin hydration and vitality.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or sensitivity | Very rare | Purified water is essentially inert; reactions are attributable to other formula components, not the water itself. |
| Transient skin barrier disruption from excessive exposure | Rare | Prolonged or repeated wetting can contribute to mild barrier compromise, but this relates to usage patterns rather than the ingredient. |
| 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 |
| Mild skin irritation or redness | Uncommon | Typically transient and concentration-dependent, more likely on sensitive or compromised skin. |
| Contact dermatitis | Rare | Allergic reactions to topical caffeine are infrequently reported. |
| Dryness or tightness | Rare | Possible with high concentrations or frequent application. |
| Stinging around the eye area | Uncommon | Can occur if product migrates into the eyes. |
| Mild skin irritation | Rare | Generally considered low-risk; occasional transient irritation reported, often linked to residual acrylic acid monomers. |
| Eye irritation | Rare | Possible if products contact the eyes; rinse thoroughly. |
| Clogged pores / comedogenic-related breakouts | Uncommon | Often anecdotal; dimethicone is largely regarded as non-comedogenic but may trap debris if skin is not cleansed well. |
| Eye irritation on accidental contact | Rare | Transient stinging or discomfort if product enters the eyes. |
