Take the skin testThe Haruharu WONDER Black Rice Night Knight Retinol Serum is a powerful yet gentle anti-aging treatment. Formulated with encapsulated retinol and natural bakuchiol, this serum works overnight to refine texture, reduce the appearance of fine lines, and restore youthful radiance. Enriched with ceramide NP and nutrient-rich black rice extract, it deeply hydrates and strengthens the skin barrier for a plump, resilient complexion. The vegan formula is non-irritating and suitable for all skin types, including sensitive skin.
Black Rice Night Knight Retinol Serum is a cushioning serum from Haruharu Wonder, a brand based in Korea. The formula is built mainly around hydration. The ingredient list runs to 35 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. Hydration is handled by Glycerin, Butylene Glycol and Ethylhexylglycerin, 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, Butylene Glycol, Ethylhexylglycerin and Water.
Cell renewal: Moderate. Retinoids, acids and enzymes that speed surface turnover, and here that comes from Retinol and Bakuchiol.
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 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.
