• 10% High-Purity Niacinamide for Targeted Efficacy: The ampoule uses 10% pharmaceutical-grade niacinamide (purity ≥99%), a concentration proven to balance oil, brighten skin, and repair barriers without excessive irritation. Unlike low-concentration products, it delivers faster, more noticeable results (e.g., reduced oiliness in 2-4 weeks, faded marks in 4-8 weeks).
• Gentle Formula with Barrier-Protecting Additives: To mitigate potential niacinamide-induced dryness, the formula is enriched with panthenol (vitamin B5) and hyaluronic acid — panthenol soothes irritation and hydrates, while hyaluronic acid locks in moisture, ensuring the skin remains soft and non-tight after use. It is free of alcohol, synthetic fragrances, parabens, and mineral oil, making it compatible with most skin types.
• Concentrated "Boosting Shot" Texture: The ampoule has a lightweight, watery texture that absorbs quickly (within 10-20 seconds) without leaving a sticky residue. Its "concentrated shot" design means a small amount (2-3 drops) is sufficient for the entire face, making it easy to layer with other skincare products (e.g., moisturizers, serums) without causing product buildup.
• Protective Packaging for Ingredient Activity: The ampoule comes in a dark glass bottle with a dropper — the dark glass blocks UV light (preventing niacinamide oxidation), and the dropper ensures sterile, precise dispensing, maintaining the ingredient’s activity from the first to the last use.

（specific ingredients are subject to product packaging; the following are core and common components）：
Core Active Ingredient:
Niacinamide (Vitamin B3): 10% high-purity (≥99%) pharmaceutical-grade niacinamide — regulates sebum production by inhibiting sebocyte activity, reduces melanin transfer to the epidermis (fading dark spots), and promotes ceramide synthesis (strengthening the skin barrier).
Hydrating & Soothing Ingredients:
Panthenol (Vitamin B5): Converts to pantothenic acid in the skin, penetrates the epidermis to hydrate, soothes mild irritation (e.g., from niacinamide), and improves skin elasticity.
Sodium Hyaluronate (Low-Molecular-Weight Hyaluronic Acid): Penetrates the upper skin layers, provides instant hydration, relieves dryness, and enhances the skin’s moisture-retention ability.
Glycerin: A humectant that attracts moisture from the air and binds it to the skin, maintaining long-term hydration and preventing post-use tightness.
Stabilizing & Gentle Base Ingredients:
Propanediol: A plant-derived solvent and humectant — dissolves active ingredients (ensuring uniform distribution) and adds mild hydration, without the irritation of alcohol.
Xanthan Gum: A natural thickener derived from microbial fermentation — stabilizes the formula, prevents ingredient separation, and ensures a smooth texture.
Disodium EDTA: A mild chelating agent — binds to metal ions in the formula, preventing oxidation and extending the product’s shelf life.
Harsh Substance-Free: Free of alcohol, synthetic fragrances, parabens, mineral oil, sulfates, and colorants — minimizes the risk of skin irritation, making it suitable for long-term use even on slightly sensitive skin.

Skin Prep: After cleansing and toning (use a mild, alcohol-free toner to balance the skin’s pH), pat the toner dry — this preps the skin for better absorption of the ampoule.
Dispense the Product: Twist open the ampoule’s dropper cap, squeeze the dropper to draw 2-3 drops of the ampoule (adjust based on skin dryness: 3-4 drops for dry skin, 2 drops for oily skin).
Apply & Absorb: Drop the product onto your palms, then gently press it onto your face (focus on oily areas like the T-zone or areas with marks/dullness) — avoid rubbing vigorously (which may cause irritation). Pat lightly with your fingertips for 10-15 seconds until fully absorbed.
Follow-Up Skincare: After the ampoule is absorbed, apply a moisturizer (gel or cream) to lock in moisture — this enhances the ampoule’s efficacy and prevents dryness. In the morning, must apply sunscreen (SPF 30+) — niacinamide may slightly increase skin sensitivity to UV rays, and sunscreen protects against sun damage and pigmentation.
Gradual Adaptation (for Beginners): If you’re new to high-concentration niacinamide (10%):
Week 1-2: Use 1-2 times a week at night, observe for redness, itching, or peeling.
Week 3-4: If no irritation occurs, increase to 3-4 times a week.
After Week 4: Gradually increase to daily use (morning and night) as skin tolerates.
