This is a new-generation functional moisturizer focusing on skin microbiome. It adopts a "prebiotic + postbiotic" dual-effect formula. By regulating the balance of skin surface flora, it builds a healthy skin microbiome environment, fundamentally improves the skin's own defense and repair ability, and improves repeated sensitivity, redness, acne, dullness and other flora imbalance problems. The formula is added with prebiotic ingredients such as fructooligosaccharides and alpha-glucan oligosaccharides, which provide nutrients for beneficial skin bacteria, inhibit the proliferation of harmful bacteria, and maintain flora homeostasis. At the same time, it is paired with probiotic fermentation products to replenish nutrients needed by the skin, strengthen the barrier and soothe discomfort. On this basis, multiple moisturizing ingredients are compounded to achieve long-term hydration and water locking, keeping the skin hydrated and plump. The product has a light cream texture, gentle and non-irritating, fragrance-free and alcohol-free, suitable for all skin types. Especially suitable for people with unstable skin condition, repeated sensitivity and oily outside/dry inside skin. As an emerging skincare concept, microbiome skincare has high topic popularity and differentiation advantages, making it a high-quality direction for brands to build segmented mindshare.
