A gentle yet effective retinol that's beginner-friendly and sensitive-skin approved. Combines microencapsulated retinol and bakuchiol to minimize irritation while boosting efficacy, tightening pores, smoothing fine lines, and providing hydration.
Black Rice Night Knight Retinol Serum / Unscented is a cushioning serum from Haruharu Wonder, a brand based in Korea. The formula is built mainly around hydration. The ingredient list runs to 33 ingredients, each broken down in full below.
By its ingredient list the formula reads as moderately cushioned — emollient enough to feel like a cream, without the heaviest occlusives near the top. The oils in it point to a dewy, emollient finish rather than a matte one. Hydration is handled by Glycerin, Ethylhexylglycerin and Butylene Glycol, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: Very high. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Glycerin, Ethylhexylglycerin, Butylene Glycol and Water.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry, Combination (dry), Combination (oily) and Oily skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, oil control and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
