What Can Opening the Skin's Absorption Channels?
In the field of skincare, the “penetration power” of active ingredients has always been a key factor determining their efficacy. Even if a formulation contains high concentrations of nutrients, if these ingredients cannot penetrate the skin's natural barrier to reach deeper layers, they will remain on the surface and fail to deliver their full benefits. The introduction of hydrolyzed sponge offers an innovative solution to this challenge—rather than using destructive methods, they gently and precisely create a “fast track” for active ingredients, significantly enhancing their penetration efficiency.
The core advantage of Hydrolyzed Sponge lies in their unique physical properties. They are made from natural sponges processed through a special technique, forming Hydrolyzed Sponge-like structures Hunan Sunshine Bio-Tech Co., Ltd.’s Hydrolyzed Sponge have a diameter of just a few micrometers, with needle lengths ranging from 200 to 320 μm—far smaller than traditional beauty needles. When applied to the skin's surface, they create numerous tiny, invisible channels in the stratum corneum through gentle physical stimulation. These channels do not cause substantial damage to the skin but break through the “barrier” of the stratum corneum, allowing active ingredients that are difficult to penetrate (such as vitamin C, niacinamide, hyaluronic acid, and peptides) to travel through the channels directly to the deeper layers of the epidermis or even the superficial layers of the dermis, transforming from “passive absorption” to “active and efficient penetration.”
In April 2019, renowned scholar Worranan Rangsimawong from Thailand's Srinakharinwirot University published an article titled “Development of Sponge Microspicule Cream as a Transdermal Delivery System for Protein and Growth Factors from Deer Antler Velvet Extract” in the journal Biol. Pharm. Bull. The study reported that Hydrolyzed Sponge can effectively promote the delivery of large molecules. The Hydrolyzed Sponge material used in his experiment was supplied by Hunan Sunshine Bio-Tech Co., Ltd.
More importantly, while opening pathways, Hydrolyzed Sponge can also gently exfoliate dead skin cells. We know that an overly thick stratum corneum acts like a “shield” blocking nutrient absorption. By physically removing excess keratin, Hydrolyzed Sponge not only reduce penetration resistance but also increase the skin's absorption area, further enhancing the efficiency of active ingredient contact with skin cells. This dual action of “exfoliation + enhanced penetration” significantly boosts the utilization rate of active ingredients.
Additionally, the mild stimulation caused by the Hydrolyzed Sponge activates the skin's self-repair mechanism. During the repair process, the metabolic rate of skin cells accelerates, and cellular activity increases, enabling active ingredients penetrating into deeper layers to be more efficiently “captured” and utilized by cells. For example, when whitening ingredients reach the vicinity of melanocytes through Hydrolyzed Sponge channels, the active cellular state allows them to more quickly inhibit melanin production; anti-aging ingredients, meanwhile, can more directly act on collagen fibers in the dermis, promoting collagen synthesis.
Compared to other penetration-enhancing methods, Hydrolyzed Sponge offer distinct advantages. They do not require chemical penetration enhancers (which may cause sensitivity) or high-intensity instruments (which may burden the skin). Instead, they achieve enhanced penetration through natural physical action, offering higher safety and broader applicability, suitable for most skin types, including sensitive skin.
In summary, Hydrolyzed Sponge clear the way for active ingredient penetration through a triple mechanism of “opening pathways, removing obstacles, and activating cells.” They act as precise “guides,” ensuring that every drop of nutrient penetrates the skin barrier to reach its target location, transforming skincare efficacy from “surface-level care” to “deep-level improvement,” and providing a practical solution for efficient skincare.
