Simple, No-Heat Serum Formulation for Brightening, Tightening, and Hydration

Question

I am looking for a simple serum formulation that can be made without using heat (cold process/hand mixable). The serum should have a lightweight, fast-absorbing texture and provide benefits such as skin brightening, tightening, moisturizing, and reducing dark spots. Could you provide a suitable formulation and mixing steps for beginners?

Lightweight, Fast-Absorbing Serum for Brightening, Tightening, and Moisturizing

Here is a simple, no-heat, hand-mixable serum formulation focusing on brightening, tightening, moisturizing, and reducing dark spots, perfect for beginners:

Ingredients:

Carbomer U21: A gel maker that creates a clear, lightweight texture and can be easily dispersed and thickened by hand stirring without heat.
GlyciWhite™: An effective ingredient for counteracting melanin production to brighten skin and reduce dark spots.
B3-Boost™ (Picolinamide): Research shows this can help reduce blemishes and dark spots.
MOIST72™: Provides high, continuous, and long-lasting moisturization.
REGU®-AGE: Helps to make the skin firmer and reduces inflammation, contributing to a tightening effect.
Preservative: Essential to prevent microbial growth (choose a suitable water-soluble, cold-processable preservative).
Distilled Water: The base of your serum.

Simple Mixing Steps (No Heat Required):

Prepare the Gel Base: Sprinkle Carbomer U21 powder onto the surface of the distilled water. Let it sit for a few minutes to wet thoroughly, then stir gently by hand until a smooth gel forms. Avoid vigorous mixing to prevent bubbles.
Add Actives: Add GlyciWhite™, MOIST72™, and REGU®-AGE to the gel base and stir until fully dissolved and incorporated.
Incorporate B3-Boost™: Dissolve B3-Boost™ powder in a small amount of a suitable glycol (like Butylene Glycol) first, then add this mixture to the main gel base and stir well.
Add Preservative: Add your chosen water-soluble preservative according to the supplier's recommended usage rate and stir thoroughly.
Final Check: Ensure all ingredients are fully dissolved and the serum has a clear, uniform consistency. Adjust pH if necessary according to the requirements of the active ingredients (generally aiming for pH 5-6.5 is suitable for most skin actives).

This formulation provides a lightweight, fast-absorbing serum texture with multiple benefits for brightening, tightening, moisturizing, and targeting dark spots, all achievable with simple hand mixing at room temperature.
