The base formula is consistent, providing these foundational benefits:

• Silky, Lightweight, and Smooth. The primary ingredients Silica and Methyl Methacrylate Crosspolymer are spherical powders that glide over the skin, filling fine lines and pores for an airbrushed, blurring effect. Triethoxycaprylylsilane is a surface treatment that makes the powder water-repellent and helps it adhere evenly.
• Oil Control & Matte Long-Lasting Finish. Silica is highly absorbent, soaking up excess sebum (oil) throughout the day. The crosspolymer also aids in oil absorption. This combination is key to the "matte long-lasting" claim, preventing shine and helping makeup stay in place.
• Hydration & Nourishment:

1. Niacinamide: A multi-tasking hero ingredient that helps regulate oil production, improves skin barrier function, and calms inflammation.
2. Sodium Hyaluronate: A powerful humectant that draws moisture to the skin's surface, preventing the powder from being overly drying.
3. Jojoba Seed Oil & Caprylic/Capric Triglyceride: Lightweight emollients that condition the skin and provide a touch of nourishment without greasiness.
4. Cordyceps Sinensis Extract: An herbal extract often associated with antioxidant and soothing properties.

• Natural, Soft-Focus Matte. The core blend delivers a translucent, light-diffusing matte finish that sets makeup without looking heavy or chalky. It "blurs" imperfections. 

Variant-Specific Benefits & Differences

The main difference between the variants is the addition of colorants and effect pigments, which slightly alter the finish and function for specific uses. 

❶  - (Translucent)

• Pure, colorless matte. Ideal for all skin tones to set makeup without altering foundation color. Best for maximum oil control and a true matte blur.

❷ & ❸ - (Light to Medium Skin Tones with Warm/Neutral Undertones)

• Key Additions: CI 77492 (Iron Oxides - Yellow), CI 77491 (Iron Oxides - Red/Brown).
• Provides light coverage and color correction. It can help even out redness or minor imperfections on its own or perfect the finish of foundation. The finish remains matte but with a slight tint.

❹ - (Translucent with a Glow)

• Key Additions: Synthetic Fluorphlogopite (Mica), CI 77891 (Titanium Dioxide), Tin Oxide.
• This variant adds subtle luminosity. Mica provides a soft, imperceptible glow, while Titanium Dioxide offers mild brightening. Tin Oxide is often used to improve adherence and texture. The result is a "matte but not flat" finish – it controls shine while giving the skin a radiant, lit-from-within quality. Not for heavy flash photography.

❺ - (A Lavender Color-Correcting Powder)

• Key Additions: CI 77007 (Ultramarines - Blue/Violet), CI 15850:1 (Red Lake), Aluminum Hydroxide (a carrier/lake former).
• This is a color-correcting powder. The lavender/soft purple tint is designed to neutralize sallow or dull yellow undertones in the skin, creating an instantly brighter, more awake complexion. It functions as a finishing powder for color correction.
• A tinted matte finish with a color-correcting effect. 

Overall Conclusion: This UODO powder is a skincare-infused, multi-functional loose powder. Its core strength is oil control and a blurring matte texture, enhanced with niacinamide and hyaluronic acid. The different variants allow users to choose based on their needs: pure oil control (01), light coverage (02/03), a radiant matte (04), or color correction (05).
