The Sunday Riley Day + Night Brighten + Plump Set is a skincare duo formulated to support daily and nightly routines focused on hydration and luminosity. The set includes two full-sized products: the Good Genes All-In-One Lactic Acid Treatment and the Luna Sleeping Night Oil. Good Genes contains lactic acid, a gentle alpha hydroxy acid derived from milk, which works to exfoliate the skin’s surface and encourage a smoother, more even complexion. It also includes licorice extract and arnica to help soothe and brighten the appearance of skin. The Luna Sleeping Night Oil combines retinol esters, avocado oil, and squalane to support overnight renewal without the irritation often associated with retinol. Avocado oil provides essential fatty acids, while squalane offers lightweight moisture. This set is designed for individuals seeking a straightforward regimen that addresses dullness, uneven texture, and dehydration. It is suitable for normal, dry, combination, and sensitive skin types, though a patch test is recommended for those new to exfoliating acids or retinol. The formulas are free from sulfates and parabens, and the overall texture of each product is lightweight and non-greasy. The Good Genes treatment applies as a smooth serum, while the Luna oil absorbs quickly with a subtle lavender scent. The set is best used in a consistent morning and evening routine, with Good Genes applied in the morning or as directed, and Luna oil used at night. This product combination aims to provide a balanced approach to skin brightness and plumpness over time, without promising instant results. The packaging is designed for easy dispensing, and the set offers a practical entry point for those exploring targeted skincare treatments.
