Key ingredients
These are the ingredients EQQUALBERRY highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: No fragrance or essential oil appears in the ingredient list on file; brand confirmation pending.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Alpha-arbutin | A stable, skin-brightening compound derived from the bearberry plant and also made synthetically. | Slows pigment production in skin cells, helping fade the look of dark spots and uneven tone over weeks.Note: Works gradually and should be paired with daily sunscreen. |
| Tranexamic acid | A synthetic amino-acid derivative used medically to reduce bleeding and in skincare for uneven tone. | Used in cosmetics for brightening and to help fade the look of dark spots; results at skincare strengths are modest and build slowly. |
| Niacinamide | A form of vitamin B3, one of the most studied ingredients in cosmetic dermatology. | Strengthens the skin barrier by boosting ceramide production, helps even out tone by limiting pigment transfer to skin cells, and can reduce the look of enlarged pores. |
| Glutathione | An antioxidant naturally produced by the body, also used topically in some brightening formulas. | Helps neutralize free radicals and is marketed for brightening, though topical absorption and efficacy are less established than oral or injectable use. |
| Beta-glucan | A polysaccharide often derived from oats or yeast. | A soothing, hydrating ingredient studied for calming sensitive skin and supporting the barrier. |
| Ceramide NP | One specific, well-studied type of ceramide used in skincare formulas. | Reinforces the skin barrier and helps it retain moisture, the same core ceramide function. |
