Ingredients
Solvent & Base Ingredients:
Water (Aqua): Main solvent, dissolves active ingredients, ensures hydrogel moisture content.
Glycerin (3%): Plant-derived humectant, maintains hydrogel moisture, prevents dryness after use.
Butylene Glycol (2.5%): Auxiliary solvent & humectant, enhances formula stability, improves hydrogel flexibility.
Propylene Glycol (1.8%): Moisturizer auxiliary, reduces hydrogel shrinkage, maintains adhesion.
Hydrogel Matrix & Adhesion Ingredients:
Sodium Polyacrylate (5%): Main hydrogel matrix, forms the gel structure, ensures high water retention.
Carbomer (0.8%): Thickener, adjusts hydrogel viscosity, improves skin adhesion.
Triethanolamine (0.2%): pH adjuster, neutralizes carbomer, enhances hydrogel stability.
Polysorbate 20 (0.3%): Surfactant, improves uniform distribution of active ingredients in the hydrogel.
Core Active Ingredients (Acne-Care & Firming):
Salicylic Acid (0.5%): Exfoliates dead skin, unclogs pores, reduces closed comedones and acne.
Centella Asiatica Extract (2%): Soothes acne redness, repairs damaged skin, enhances barrier function.
Melaleuca Alternifolia (Tea Tree) Leaf Extract (1.5%): Regulates oil secretion, has antibacterial properties, alleviates acne inflammation.
Hyaluronic Acid (1.8%): Multi-molecular hyaluronic acid, replenishes deep moisture, improves skin hydration.
Palmitoyl Tripeptide-1 (0.3%): Stimulates collagen production, enhances chin skin elasticity, reduces sagging.
Palmitoyl Tetrapeptide-7 (0.3%): Synergizes with tripeptide-1, strengthens firming effect, soothes skin irritation.
Soothing & Moisturizing Auxiliaries:
Panthenol (Vitamin B5, 1.2%): Relieves dryness and tightness, improves skin barrier repair.
Allantoin (0.6%): Soothes sensitive skin, accelerates repair of minor acne damage.
Aloe Barbadensis Leaf Extract (1%): Enhances soothing effect, reduces irritation from salicylic acid.
Trehalose (0.8%): Natural humectant, maintains skin moisture balance, resists environmental dryness.
Stabilizers & Preservatives:
Phenoxyethanol (0.5%): Mild preservative, extends product shelf life, safe for sensitive skin.
Ethylhexylglycerin (0.4%): Auxiliary preservative & moisturizer, enhances phenoxyethanol’s preservative effect.
Disodium EDTA (0.1%): Chelating agent, stabilizes the formula, prevents active ingredient oxidation.
Soothing & Cooling Ingredient:
Menthol (0.05%): Provides a mild cooling sensation, relieves acne discomfort, enhances user experience (low concentration to avoid irritation).
How to Use
How to Use
Prep Before Use: Clean the chin area thoroughly with a mild cleanser (remove makeup if wearing it), then pat the chin dry with a clean towel—ensure no oil or residue remains (oils may affect hydrogel adhesion).
Open & Apply the Pack: Tear open the sealed bag along the notch, take out the hydrogel chin pack, and remove the white protective film (attached to the back of the hydrogel) to expose the adhesive side.
Align & Press: Align the pack with the center of your chin (the curved part of the pack matches the chin’s contour), then press the pack gently from the center to the edges—ensure there are no air bubbles between the pack and the skin (air bubbles may cause slipping).
Wait for Essence Absorption: Leave the pack on for 20-25 minutes (do not exceed 30 minutes, as the hydrogel may dry out and reverse absorb skin moisture). During this period, avoid excessive movement of the chin (e.g., talking, eating) to maintain adhesion.
Post-Use Care: Remove the pack, gently pat the remaining essence on the chin with your fingertips until fully absorbed (no need to rinse). For better results:
If you have acne/closed comedones: Follow with an oil-controlling toner to shrink pores.
If you have dry/sagging chin: Follow with a lightweight moisturizer to lock in moisture.
Precautions:
Perform a patch test before first use: Apply a small piece of the hydrogel (or a drop of its essence) to the inner arm, observe for 24 hours—discontinue use if redness, itching, or stinging occurs.
Do not use on broken acne, sunburned, or irritated chin skin: Salicylic acid may exacerbate discomfort on damaged skin.
Store in a cool, dry place away from direct sunlight: High temperature will reduce the hydrogel’s moisture content and adhesion; refrigeration (4-8℃) for 10 minutes before use can enhance the cooling and soothing effect.
