Formula Review

Your formula includes a good selection of ingredients that target your stated goals.

• Whitening and Brightening: The combination of Safe-B3 (Niacinamide) at 4% and GlucoBright (Acetyl Glucosamine) at 4% is excellent for brightening the skin tone and reducing dark spots. Niacinamide also offers multiple benefits including strengthening the skin barrier, reducing redness, and improving skin texture, which are beneficial for sensitive skin.
• Lifting and Firming: Methylsilanol Mannuronate at 5% is included for its firming and lifting properties.
• Wrinkle Reduction: Pep®-Coll (Palmitoyl Tripeptide-5) at 3% is a peptide known to stimulate collagen production and effectively reduce the appearance of wrinkles. Safe-B3 (Niacinamide) also contributes to wrinkle reduction by supporting collagen and ceramide production. Mineral Ready™ (Mn+Zn+Cu) at 2% can help improve skin roughness and reduce wrinkle depth by supporting skin oxygenation and metabolism.
• Moisturization: The formula contains Purified Water as the base, and Safe-B3 (Niacinamide) and GlucoBright (Acetyl Glucosamine) help improve skin hydration and stimulate hyaluronic acid production. Methylsilanol Mannuronate also contributes to maintaining skin structure.
• Anti-Glycation: Ume Extract at 2% helps to combat skin yellowing caused by glycation, contributing to a brighter, more radiant complexion ("ขาวออร่า").
• Sensitive Skin: Safe-B3 (Niacinamide) helps strengthen the skin barrier and reduce irritation. Licorice Extract (Licochalcone A 1%, Water-Soluble) at 1% is primarily included for its anti-inflammatory and anti-irritant properties, which is very beneficial for sensitive skin and helps reduce redness. Note that this specific type of licorice extract is not primarily for whitening.
• Penetration Enhancement: Dimethyl Isosorbide (DMI) at 3% helps enhance the penetration of the active ingredients into the skin, improving their efficacy.
• Formula Stability: ActiveProtec™ OX at 1% acts as an antioxidant to protect the formula ingredients from degradation.
• Emulsifier and Texture: Satin Cream Maker™ at 1% is used to create the cream texture.
• Odor Control: Odor-Kill™ at 1% is included to help absorb any undesirable odors from the raw materials. Be aware that it can also absorb fragrance if you plan to add any.
• Preservation: Phenoxyethanol SA at 1% provides broad-spectrum preservation for the formula.

Suggestions for Improvement or Consideration

1. Whitening Focus: The formula contains effective brightening agents (Niacinamide, Acetyl Glucosamine). The Licorice Extract included is mainly for anti-irritation. If you desire a stronger direct whitening effect, you might consider adding a dedicated whitening ingredient like Alpha Arbutin or a different type of Licorice Extract known for its Glabridin content, ensuring compatibility with the existing ingredients and pH, and being mindful of potential increased sensitivity.
2. pH Compatibility: Ensure the final pH of your cream is within the optimal range for all active ingredients, particularly Methylsilanol Mannuronate (around pH 5) and the Niacinamide/Acetyl Glucosamine combination (pH 3-7, best 4-7). A pH between 5-6 should work well for most ingredients in this formula. Also, verify compatibility of Methylsilanol Mannuronate with the levels of DMI and Caprylyl Glycol in your formula.
3. Odor-Kill™ and Fragrance: If you plan to add fragrance to your cream, be aware that Odor-Kill™ may reduce the intensity of the scent. If the raw materials do not have a strong unpleasant odor, you could consider reducing or omitting Odor-Kill™.

Overall, this is a well-formulated cream targeting multiple skin concerns, with ingredients suitable for sensitive skin. The concentrations of the active ingredients are within recommended ranges for efficacy.
