Frequently asked questions
Is the EQQUALBERRY Vitamin Illuminating Serum a vitamin C serum?
Not in the traditional sense. Despite the name, the formula is built on 40% acerola fruit water with 4% niacinamide, 2% arbutin and tranexamic acid, plus only a small amount of a vitamin C derivative. Its brightening approach is multi-ingredient rather than high-dose ascorbic acid.
Is it good for sensitive skin?
It contains many actives and botanicals, and some reviewers report burning or irritation. Patch-test before regular use, especially if you already use exfoliating acids or retinoids.
Can I use it with retinol?
There are no direct conflicts, but stacking a multi-active brightening serum with retinol can be irritating for some skin. Try the serum in the morning and retinol at night, and combine only once your skin tolerates both separately.
Is it fungal-acne safe?
We cannot confirm fungal-acne safety from the published ingredient highlights alone. If you manage malassezia-prone skin, check the full ingredient list on the packaging against a fungal-acne database before buying.
