Facial Spray Formulation Review

Based on your skin type (sensitive, acne-prone, oily yet dehydrated, weak, prone to redness and uneven texture) and your goals (reduce oiliness, balance skin, protect from pollution), the proposed facial spray formulation is well-suited and the ingredients are generally compatible.

Here's a breakdown of the ingredients and their benefits for your skin:

• Niacinamide (Vitamin B3): At 3%, this ingredient is effective in reducing oiliness, minimizing redness and hyperpigmentation, and strengthening the skin barrier. It also helps improve skin hydration by stimulating ceramide production and is beneficial for acne-prone skin.
• Licorice Extract (Licochalcone A 1%): Included at 1%, this extract is known for its anti-inflammatory properties. It helps reduce skin inflammation, redness from acne, and overall irritation. It also contributes to controlling facial oil.
• Ectoin: At 2%, Ectoin provides significant protection and repair benefits. It helps build and strengthen the skin's protective barrier, offers anti-irritant effects, and provides protection against environmental stressors like pollution, UV, and IR light. It also has moisturizing properties.
• Prebiotic (such as Prebio-care): At 3%, a skin prebiotic helps nourish the beneficial bacteria on your skin, promoting a healthy skin microbiome. This can help balance the skin, reduce itching and irritation, restore the skin barrier, and reduce the growth of acne-causing bacteria.
• Beta Glucan (from Saccharomyces cerevisiae extract): At 3%, Beta Glucan helps protect the skin from irritation, strengthens the skin's natural defenses, and reduces allergic reactions. It is beneficial for restoring weak or irritated skin.

Compatibility and Formulation Notes:

All the ingredients you've chosen are water-soluble or dispersible, making them suitable for a spray formulation. To ensure stability and effectiveness, the final pH of your spray should be adjusted to be within the range of 5.0-6.5, which is compatible with all these ingredients and optimal for skin.

Beta Glucan from Saccharomyces cerevisiae extract may not dissolve completely clear in water and might settle over time. It is recommended to shake the product well before each use to ensure even distribution.

When preparing the formulation, mix all ingredients in the water phase. Be mindful of temperature for Beta Glucan (below 50°C) and avoid prolonged heating for Niacinamide.

This combination of ingredients directly addresses your concerns regarding oiliness, sensitivity, redness, and barrier function, while also providing protection against pollution.
