Proposed Water-Based Formula for Aging, Acne-Prone, Dehydrated Skin

Thank you for providing your detailed formula for a water-based product (น้ำตบ) designed for skin aged 40 with concerns including roughness, large pores, clogged pores, blackheads, fine lines, and dehydrated oily skin. The desired texture is slightly thicker than water, intended for use as the first step after cleansing.

Your proposed formula includes a thoughtful combination of ingredients targeting these specific concerns. Here is a breakdown of the key components and their potential benefits:

• Purified Water: Serves as the base solvent for the water-based formula.
• Lactobionic Acid: A type of Polyhydroxy Acid (PHA) known for gentle exfoliation, helping to improve skin texture and clarity, which can address roughness and clogged pores. It also has moisturizing properties, beneficial for dehydrated skin.
• Willow Bark Extract (Natural Salicylic Acid): Contains Salicylic Acid, a Beta Hydroxy Acid (BHA). It helps exfoliate the skin, clear clogged pores, and can be effective for acne and blackheads. It also has anti-inflammatory and antioxidant properties.
• Calendula Extract (Water Soluble): Known for its anti-inflammatory, soothing, and wound-healing properties. It can help reduce redness and irritation, suitable for sensitive or acne-prone skin.
• Cucumber Extract: Provides softening and soothing effects, and helps reduce irritation. It is suitable for the face and eye area.
• Calcium Pantothenate: A form of Vitamin B5, which helps to moisturize the skin, reduce redness, and soothe irritation.
• Allantoin: Occurs naturally and is widely used for its ability to reduce irritation, soothe skin, and promote tissue regeneration. It is gentle and suitable for sensitive skin.
• Dipotassium Glycyrrhizate: Derived from licorice extract, it is effective in reducing inflammation and allergies, helping to strengthen the skin barrier. It is known for its skin-soothing properties.
• Quick-Coll®: An Amino Acid/Copper Complex designed to stimulate the production of collagen and elastin, which can help improve skin firmness and reduce the appearance of fine lines and wrinkles.
• Pure-Genistein™: A soy extract containing Genistein, a phytoestrogen. It is believed to have potential benefits for mature skin, including helping with hydration and potentially addressing concerns related to reduced estrogen levels in aging skin.
• Hydroxyethyl Cellulose (HEC): A non-ionic polymer used as a thickener. At 1%, it will help achieve the desired texture that is slightly thicker than water, suitable for a 'น้ำตบ' consistency.
• Dimethyl Isosorbide (DMI): Acts as a penetration enhancer, helping other active ingredients like Lactobionic Acid, Willow Bark Extract, and extracts to penetrate the skin more effectively.
• Odor-Kill™: A deodorant ingredient that helps absorb unwanted odors in the formula.
• Mild Preserved Eco™: A preservative blend that is gentle and not classified as a traditional preservative by some regulations, helping to prevent microbial growth in the formula.

Overall, the combination of exfoliating acids (Lactobionic Acid, Willow Bark Extract), soothing and hydrating extracts (Calendula, Cucumber, Calcium Pantothenate, Allantoin, Dipotassium Glycyrrhizate), anti-aging peptides (Quick-Coll®), and penetration enhancers (Dimethyl Isosorbide) appears well-suited to address the multiple concerns of aging, acne-prone, and dehydrated skin. The inclusion of Hydroxyethyl Cellulose at 1% should provide the desired slightly viscous, water-like texture for use as a first treatment step after cleansing.
