    Hello, it is my first time making a moisturizer.

    Main Goals: I want a moisturizer that provides hydration, soothes the skin, and is suitable for acne-prone skin.

    Formulation:

    • 3.00% Niacinamide: Known for its anti-inflammatory properties and helps improve skin barrier function.

    • 3.00% Melaleuca Alternifolia (Tea Tree) Leaf Oil: Antimicrobial and anti-inflammatory, helpful for acne management.

    • 2.00% Glycine Soja (Soybean) Seed Extract: Rich in antioxidants and helps in skin conditioning.

    • 2.00% Aloe Vera Extract: Provides hydration and has soothing properties.

    • 6.00% Glycerin: Acts as a humectant and draws moisture into the skin.

    • 5.00% D-Panthenol: Moisturizes and helps with skin healing.

    • 3.00% Simmondsia Chinensis (Jojoba) Seed Oil: Mimics the skin’s natural oils and provides hydration without clogging pores.

    • 5.00% Butyrospermum Parkii (Shea) Butter: Emollient and moisturizing, with anti-inflammatory properties.

    • 4.00% PEG 100 Stearate: Emulsifier that helps blend ingredients together.

    • 2.00% Polysorbate 80: Emulsifier.

    • 2.00% Dimethicone: Provides a silky texture and acts as a barrier to lock in moisture.

    • 0.10% Citric Acid: pH adjuster.

    • 0.10% Sodium Citrate: pH buffer.

    • 1.0% Tetrasodium EDTA: Chelating agent that helps improve stability and effectiveness of the formulation.

    • 2.00% Propylene Glycol: Humectant that helps retain moisture.

    • 1.00% Hydroxypropyl Methyl Cellulose: Thickening agent that provides texture and stability.

    • 1.00% Euxyl PE 9010: Preservative to ensure product safety and longevity.

    • 0.150% Rose Scent: Fragrance for a pleasant smell.

    • 57.65% Water: Solvent that forms the base of the formulation.

    Concerns: Are there any potential issues with ingredient compatibility or skin sensitivity? Is this formulation suitable for normal to oily skin types as well as for acne-prone skin?

    Lower EDTA concentration to 0.1-0.2%

    Suggest adding preservation vs fungi and Gram positive bacteria.
