Formulation Review

You have selected excellent ingredients for both your day and night creams, targeting hydration, anti-aging, and skin revitalization.

Day Cream Ingredients:

• Pitera (Galactomyces Ferment Filtrate): Great for revitalizing the skin, improving texture, and providing hydration.
• Pal-GHK (Matrixyl 3000): A powerful peptide blend known to stimulate collagen production, effectively reducing the appearance of wrinkles and improving skin elasticity and firmness.
• Vitamin B3 (Niacinamide): A versatile ingredient that helps reduce wrinkles, improve skin barrier function (leading to better moisture retention), reduce redness and hyperpigmentation (contributing to a brighter, more even skin tone), and can help control oiliness.

This combination is strong for anti-aging, hydration, and provides some brightening effect from Vitamin B3. To enhance the "whitening" aspect specifically, you might consider adding a dedicated whitening agent.

Night Cream Ingredients:

• Pitera (Galactomyces Ferment Filtrate): Provides revitalization and hydration.
• Hyaluronic Acid (Double Hyaluron Liquid): Excellent for deep and surface hydration, plumping the skin and reducing dryness.
• Water lock (Polyquaternium-51): Works synergistically with Hyaluronic Acid to prevent transepidermal water loss, keeping the skin moisturized and soft.
• Wakame Extract: Known for its anti-aging properties, helping to lift and tighten the skin and stimulate collagen synthesis.

This night cream formulation is very focused on hydration, preventing dryness, and anti-aging. To address the goal of "หน้าขาวใส" (white and clear face) and further enhance anti-aging, you could consider additions.

Suggestions for Enhancement

Based on your goals for whitening, plumpness, softness, moisture, and wrinkle reduction:

1. For Enhanced Whitening: While Vitamin B3 in your day cream helps with brightening and even tone, adding Alpha Arbutin to either or both formulations would significantly boost the whitening effect. Alpha Arbutin is known for effectively reducing melanin production, leading to brighter and clearer skin.
2. For Enhanced Anti-Aging and Plumpness (Night Cream): Your night cream has Wakame Extract for anti-aging, but adding Pal-GHK (Matrixyl 3000) (which you are already using in your day cream) to the night cream would provide a stronger peptide synergy for wrinkle reduction and skin firmness, contributing further to a "เด้งฟู" (bouncy and plump) look upon waking.
3. For Comprehensive Benefits in Night Cream: You could also consider adding Vitamin B3 (Niacinamide) to your night cream. It complements the other ingredients by improving barrier function, adding moisture, and contributing to a clearer complexion.

Adding Alpha Arbutin is the most direct way to enhance the whitening goal. Adding Pal-GHK or Vitamin B3 to the night cream would further strengthen its anti-aging and overall skin health benefits.

Your current ingredients are a great start, and adding one or two more targeted actives like Alpha Arbutin would help you more fully achieve all your desired results.
