KSECRET Seoul 1988 Glow Serum: Niacinamide 15%+Yuja

KSECRET KSECRET Seoul 1988 Glow Serum: Niacinamide 15% + Yuja is a multifunctional serum formulated to address hyperpigmentation, post-acne spots, enlarged pores and uneven skin tone. Its formula is based on 15% Niacinamide, a key active ingredient in skincare that helps regulate sebum, visually minimize pores, improve skin texture and gradually fade pigmented and post-acne spots. Yuja (or yuzu) extract, a hybrid fruit between mandarin and lemon, is well known for its anti-aging and anti-hyperpigmentation properties. This fruit is rich in antioxidants that promote collagen production, thereby reducing the appearance of fine lines and wrinkles. The formula is also reinforced with Glutathione, a powerful antioxidant that helps even out skin tone and protect against oxidative stress, Panthenol and Allantoin, which soothe the skin and strengthen the protective barrier, as well as Sodium Hyaluronate, which provides deep hydration and helps retain skin elasticity. With regular use, the serum helps reduce spots and achieve a natural glow. It is ideal for combination, oily and blemish-prone skin, but also suitable for sensitive skin that needs glow and gentle treatment at the same time.

Its formula is hypoallergenic, dermatologically tested and does not contain ingredients harmful to the skin, such as: alcohol, parabens, silicones, sulfates, artificial fragrance and artificial colorants.

How to use

After cleansing your skin with your regular cleanser, take a moderate amount into your hands and spread it over the face and neck until the skin has fully absorbed it, avoiding the eye area. If necessary, reapply an additional layer on problem areas with spots. Continue with the other steps of your routine. To maximize effect and prevent product oxidation, store in a cool, dark place. The next day, apply a sunscreen with SPF 50+.
