Troubleshooting Common Issues in DIY Skincare

Even the most experienced home formulators run into hiccups now and then. A balm that won’t set. A lotion that separates. A serum that feels... off. These moments aren’t failures, they’re part of the learning process. The good news? Most common issues in DIY skincare have simple explanations and even simpler fixes.

This guide is your go-to troubleshooting companion, helping you diagnose and correct common formulation mishaps with confidence and curiosity.

‍

1. My Balm Won’t Harden

Possible Causes:

• Too much liquid oil
• Room temperature is too warm
• Not enough solidifying agents like beeswax or butters

Solutions:

• Increase the amount of beeswax slightly in your next batch
• Try storing in the fridge for 24 hours to help set the formula
• Consider adding a touch of cocoa butter or candelilla wax for firmer texture

‍

2. My Butter is Grainy

This is especially common with shea and mango butter.

Why It Happens:

• Butters melted and cooled too slowly, allowing crystals to form

Fix:

• Gently melt the butter until fully liquid
• Place the container directly into the freezer to solidify quickly
• Once solid, re-whip if needed for texture

‍

3. My Oil-Based Serum Feels Greasy

Possible Causes:

• Too much of a heavy oil like castor or avocado
• Applied too much product at once

Solutions:

• Use lighter oils like jojoba, squalane, or grapeseed (these absorb quickly and feel less greasy on skin)
• Reduce application to 1–2 drops and press into damp skin
• Consider adding a small amount of dry-feel esters (light synthetic ingredients used to reduce oiliness) if formulating at an advanced level

‍

4. My Lotion or Cream is Separating

Emulsions are tricky but so rewarding when done right.

Why It Happens:

• Incorrect oil-to-water ratio
• Inadequate emulsifier
• Didn’t blend at the right temperature or for long enough

Fix:

• Double-check your formula's oil/water balance
• Use a reliable emulsifier and follow supplier instructions
• Blend with a stick blender for several minutes until fully emulsified
• Allow the emulsion to cool undisturbed

‍

5. There's Mold or Smell in My Product

Signs:

• Foul, sour, or musty odor
• Color changes or visible growth
• Separation or bubbling

Causes:

• Water-based product without a preservative
• Contaminated tools or containers
• Touching product directly with fingers

Prevention:

• Preservatives protect against bacteria, yeast, and mold; antioxidants like vitamin E only slow oil oxidation
• Always use a broad-spectrum preservative in water-based products
• Sanitize all tools, jars, and surfaces
• Use clean spatulas or pumps to dispense

‍

6. My Product Feels Sticky or Tacky

Causes:

• Too much glycerin or honey
• Overuse of aloe vera gel or certain thickeners

Solutions:

• Reduce the sticky ingredient by 10–20%
• Balance with more emollient oils or humectants like propanediol
• Add a small amount of starch (like arrowroot) to absorb excess moisture feel

‍

7. My Product Smells 'Off'

Possible Causes:

• Ingredients are oxidizing (like rancid oils)
• Essential oils reacting over time
• No antioxidant included

Fix:

• Store oils and finished products in a cool, dark place
• Always include an antioxidant like vitamin E (tocopherol) in oil-based formulas
• Check oil shelf life before formulating

‍

8. My Finished Product is Too Thin or Too Thick

To Thicken:

• Add more butters, beeswax, or thickener (like cetyl alcohol or xanthan gum)
• Reduce liquid oil or hydrosol content

To Thin:

• Add a few drops of a carrier oil to soften balms
• Dilute thick products with a light oil or hydrosol if appropriate

Always test adjustments in small batches.

‍

9. I Have a Reaction or Irritation

Possible Triggers:

• Essential oils used at too high a dilution
• Known allergens (citrus oils, lanolin, etc.)
• Product pH outside of skin-friendly range (4.5–5.5)

What to Do:

• Stop using immediately and note the ingredients
• Always patch test new formulas before full use
• Keep a formulation journal to track reactions and preferences

‍

10. I Don’t Know What Went Wrong!

That’s okay. This is part of the path.

Helpful Tips:

• Keep notes as you formulate (include ingredients, ratios, method, temperature, etc.)
• Work in small batches to reduce waste
• Use consistent tools like measuring scales and mixing equipment
• When in doubt, simplify: return to a basic recipe and build from there
