The Most Common Formulation Challenges in Skincare - and How Manufacturers Solve Them
Creating a skincare product may look simple from the outside, but behind every smooth, effective formula is a long scientific process filled with challenges. From ingredient reactions to pH imbalance, skincare formulations require skill, patience, and strict testing. At Sprivil, we solve these challenges every day to create products that are safe, stable, and high-performing.
Here are the most common formulation challenges-and how expert manufacturers overcome them.
1. pH Imbalance
Every skincare product must match the skin’s natural pH level, which is around 4.5 to 5.5.
If the pH is too high or too low, the product may:
- Irritate skin
- Become unstable
- Reduce active ingredient performance
How manufacturers solve it:
Sprivil’s chemists test pH at multiple stages of formulation. We adjust pH using safe acids or bases until the formula falls within the ideal range for both performance and safety.
2. Ingredient Incompatibility
Not all ingredients “get along.” Mixing the wrong actives can:
- Change color
- Cause separation
- Reduce effectiveness
- Create irritation
For example:
- Vitamin C and Niacinamide can clash without proper stabilization.
- AHAs lower pH too much for delicate peptides.
- Retinol breaks down easily with light or air exposure.
How manufacturers solve it:
Sprivil runs compatibility tests to study ingredient behavior. We adjust:
- pH
- Solvents
- Stabilizers
- Encapsulation methods
- Order of ingredient mixing
This keeps the formula active and safe.
3. Viscosity & Texture Problems
Changing even 1% of an ingredient can affect:
- Thickness
- Spreadability
- Feel on skin
- Absorption rate
A serum that feels too sticky or a cream that feels too greasy will fail in the market.
How manufacturers solve it:
Sprivil uses rheology (texture science) to:
- Fine-tune emulsifiers
- Adjust thickeners
- Optimize oil/water balance
- This ensures the product has a luxurious, consumer-friendly feel.
4. Product Separation
Emulsions (oil + water mixtures) are the backbone of skincare. But when the emulsion isn’t stable, products may:
- Separate
- Become grainy
- Lose thickness
How manufacturers solve it:
We ensure proper emulsification with:
- High-shear mixers
- Temperature-controlled processing
- Carefully selected stabilizers
- Correct phase addition order
This prevents separation during shelf life.
5. Color or Odor Changes Over Time
Products can discolor or develop an odd smell due to:
- Oxidation
- Contaminated raw materials
- Unstable actives
- Poor packaging choices
How manufacturers solve it:
Sprivil uses:
- Antioxidants
- Encapsulated actives
- Purified raw materials
- UV-protective packaging (especially for Vitamin C, retinol, AHA serums)
6. Microbial Growth
Water-based products can easily grow mold or bacteria if not preserved correctly.
How manufacturers solve it:
- We conduct microbial tests and use globally approved, safe preservatives.
- Sprivil also manufactures in clean-room environments, reducing contamination risk.
7. Fragrance Compatibility
Fragrances can change pH and destabilize formulas.
How manufacturers solve it:
- We test every fragrance in the formula to ensure:
- It doesn’t separate
- It doesn’t impact color
- It doesn’t reduce active performance
This report is essential for regulatory approvals and product launches.
