Overview
A gel serum from Haruharu combining centella, niacinamide, tranexamic acid and vitamin C, meant to follow cleansing. Unscented, in a compact 1.01 fl oz size.
This serum stacks four separate active ingredients rather than centering on one, which is typical of multi-benefit Korean serums aimed at tone and texture together. The listing states it addresses skin after cleansing, positioning it as an early step layered before heavier creams.
- Centella, niacinamide, tranexamic acid, vitamin C
- Gel texture
- Unscented
- 1.01 fl oz
Who it's for
Suits anyone wanting a multi-active serum for tone evening and general skin support rather than a single-ingredient treatment. The unscented gel format works for most skin types, though the product data does not specify a skin type.
Pros and cons
- Combines four named actives in one serum
- Unscented gel texture
- Positioned as an after-cleansing step
- Compact 1.01 fl oz size for travel
- No stated skin type on the listing
- Small size compared to some serums
Performance notes
Niacinamide and vitamin C both target tone and brightness through different pathways, while tranexamic acid is more commonly used for discoloration and centella adds a soothing element, so the combination leans toward an all-in-one tone-support serum. Being a gel rather than an oil suggests a lighter, faster-absorbing texture.
