How to Build a Harmonized Cosmetic Series: Water-Based & Oil-Based Compatibility

In the world of skincare and color cosmetics, brands increasingly offer complete product lines — from serums to creams, primers to foundations. However, poorly matched formulations can result in ingredient clashes: pilling, greasiness, inconsistent absorption, or reduced efficacy.

At our OEM factory, with over 25 years of R&D experience, we specialize in custom formulation of cohesive product series that are compatible, synergistic, and non-conflicting.

Each product in your line is designed to work together — not against each other.

How Do We Ensure Compatibility Within a Series?

✅ Cross-ingredient compatibility checks

We evaluate pH, solubility, oil-water ratios, and active ingredients to ensure products won’t react negatively when layered.

✅ Balanced water- and oil-based formulas

We engineer emulsions that allow water-based serums and oil-based creams to layer smoothly — avoiding pilling or greasy residue.

✅ Real-world usage simulation

Our lab mimics real application orders to confirm smooth texture, absorption, and visual appearance when products are used in sequence.

✅ Functional synergy

For example: niacinamide in a brightening serum won't conflict with UV filters in your sunscreen; or matte primers are designed to enhance long-wear foundation performance.

Common Product Conflicts — Solved by Us

• ❌ Pilling from serum + cream → ✅ Adjusted emulsifier & slow-release agents

• ❌ White cast with sunscreen → ✅ Transparent filter system & pigment control

• ❌ Flaking between primer + foundation → ✅ Base system matched (silicone vs. water)

• ❌ Poor makeup adherence after skincare → ✅ Film-formers & moisture-locking agents applied
