Existing pulse oximeters have impaired accuracy in measuring blood oxygen levels (SpO2) in patients of color, where the presence of melanin in the skin tends to interfere with measurements of pulse oximetry, resulting in an overestimation of SpO2. Thus, the pulse oximeter often reports a higher oxygen saturation for patients with darker skin tones, often with increasing bias as the actual saturation (SaO2) decreases. This bias is further reinforced by calibration based on individuals with light skin pigmentation, which may lead to inequitable healthcare for patients of color. Our proposed solution is to modify current pulse oximetry calculations—which utilize the relative tissue absorbance of red and infrared light to estimate SpO2—to account for the concentration of melanin by additionally measuring the skin absorbance of UV˜A light. This derived concentration of melanin can then be used to modify the pulse oximetry algorithm output, thus estimating SpO2 more accurately for patients of color.

The invention belongs to the technical field of cosmetics, and discloses a moisturizing toner and a preparation method thereof. The method comprises the following steps: dissolving lecithin, cholesterol and grease in an organic solvent to prepare a lipid phase; dissolving collagen fragments of which the molecular weight is less than 10 kDa in water to prepare a first water phase; emulsifying the lipid phase and the first water phase while stirring, and removing the organic solvent to obtain a liposome dispersion liquid encapsulating collagen fragments; and dispersing hyaluronic acid and one or more cosmetically acceptable active components in a water-phase matrix, adding the liposome dispersion liquid, and adjusting the pH value to obtain the transparent or semitransparent moisturizing toner composition. Test results show that compared with a contrast formula without collagen lipidosome, the toner provided by the invention can more effectively promote collagen fragments to be delivered to dermis through epidermis, reduce transdermal moisture loss and improve the water content of cuticle, and has the advantages of light skin feeling, no stickiness and lasting moisturizing.

The invention relates to the technical field of cosmetics, and particularly discloses a process for preparing stepped temperature control filled skincare Guifu cream and application of the skincare Guifu cream. The core of the process is that a precise temperature control flow of high-temperature emulsification, stepped cooling, low-temperature active matter addition and quick-freezing shaping is adopted, and the flow and a specifically-formed formula system are in synergistic effect, so that a unique and stable three-dimensional net-shaped structure is successfully constructed in paste; the structure overcomes the long-standing three technical bottlenecks that thermosensitive active ingredients are easy to inactivate, high-content powder and a grease system are easy to separate and unstable, and a final product is thick and sticky in skin feeling in the traditional high-temperature emulsification process, and the finally obtained product not only retains the efficacy of the active ingredients to the maximum extent, but also has excellent heat resistance, cold resistance and storage stability, and is suitable for industrial production. Furthermore, the cream body is endowed with a light skin feeling of'water dissolving once smearing ', and the dual effects of instant brightening modification and long-acting nourishing and repairing are successfully realized.

The present application relates to the field of fine chemical technology, and discloses a water-locking and moisturizing liquid lip gloss and a preparation method thereof. The present application constructs a dual-phase rheological regulation network combining rigid skeleton support and flexible hydrogen bond bridging, which significantly improves the rheological properties of the product. The liquid lip gloss comprises deionized water, a polyol moisturizing compound system composed of glycerol, propylene glycol and polyethylene glycol, a film-forming polymer, and a thixotropic regulator compounded by organoammonium salt modified hectorite and xanthan gum.
