Key Facts
- Interior car temperatures can reach 116°F when outside temperatures are just 70°F.
- Lipstick typically melts between 125°F and 185°F, varying by brand and formulation.
- Foundations, particularly liquid and cream-based, can separate and change consistency when exposed to high temperatures.
- Powder-based products, while more heat-stable, can still crack or change texture if subjected to extreme heat and temperature fluctuations.
- Natural or organic makeup products often have lower melting points due to the absence of synthetic stabilizers.
Will My Makeup Stuff Melt in the Hot Car?
Yes, your makeup can definitely melt in a hot car. The interior of a car acts like a greenhouse, trapping heat and quickly raising the temperature to levels that can damage many types of cosmetics. It’s not just melting that’s a concern; high temperatures can also alter the texture, color, and effectiveness of your favorite products. Lipstick is the most vulnerable, often turning into a gooey mess, while foundations can separate, and powders can crack.
What Temperature Does Makeup Melt?
The melting point of makeup varies depending on the product’s formulation. Here’s a general idea:
- Lipstick: Most lipsticks start to soften around 125°F and can fully melt between 150°F and 185°F.
- Foundation: Liquid and cream foundations can separate at temperatures above 90°F.
- Cream Blush/Eyeshadow: These products often have a lower melting point than lipstick, starting to soften around 100°F.
- Powder Products: While more stable, powders can still be affected by heat and humidity, leading to changes in texture or cracking.
How Hot Does It Get Inside a Car?
On a sunny day, even when it doesn’t seem that hot outside, the temperature inside a car can skyrocket. Here is an approximate guide:
- 70°F outside: Inside temperature can reach 104°F within 30 minutes and 113°F within an hour.
- 80°F outside: Inside temperature can reach 114°F within 30 minutes and 123°F within an hour.
- 90°F outside: Inside temperature can reach 124°F within 30 minutes and 133°F within an hour.
What Happens to Makeup in Heat?
Heat can wreak havoc on your makeup in several ways:
- Melting: As mentioned, lipsticks and cream-based products are prone to melting, changing shape, and becoming unusable.
- Separation: Liquid foundations, concealers, and even some mascaras can separate into their oil and pigment components, ruining their consistency.
- Texture Changes: Heat can cause powders to crack or become hard, and it can make creams and liquids either too runny or thick and clumpy.
- Color Changes: Some pigments, especially in natural or organic products, can change color when exposed to high temperatures.
- Bacterial Growth: Heat can create a breeding ground for bacteria, especially in liquid products, potentially leading to skin irritation or infections.
Which Makeup Products Are Most at Risk?
While all makeup can be affected by heat, some products are more vulnerable than others:
- Lipsticks: Due to their wax and oil base, lipsticks are highly susceptible to melting.
- Cream Blush/Highlighter/Contour: These products often have a creamy or balm-like texture that can easily melt.
- Liquid Foundation/Concealer: Heat can cause these products to separate and become watery or clumpy.
- Pencil Eyeliners/Brow Pencils: The wax in these pencils can soften, making them difficult to apply and prone to breaking.
- Mascara: While mascara doesn’t typically melt, heat can dry it out, making it clumpy and flaky.
What Types of Makeup Melt the Easiest in a Hot Car?
Certain types of makeup are more prone to melting than others due to their ingredients and formulation.
Lipstick
Lipsticks are usually the first casualties in a hot car. Their primary ingredients—waxes, oils, and pigments—have relatively low melting points. The waxes provide structure, but when exposed to heat, they soften and eventually melt, leading to a misshapen or completely liquefied product.
Cream-Based Products
This category includes cream blush, cream eyeshadow, cream contour, and some types of foundation. These products are formulated with a blend of oils and waxes to give them their creamy texture. While this makes them easy to blend, it also makes them vulnerable to heat.
Pencil Products
Eyeliners, lip liners, and brow pencils often contain waxes similar to those found in lipsticks. While they might not melt completely, they can soften significantly, making them difficult to apply and prone to breakage.
Natural or Organic Makeup
Makeup products marketed as “natural” or “organic” often use plant-based oils and waxes, which can have lower melting points than synthetic alternatives. They may also lack the stabilizers found in conventional makeup, making them more susceptible to heat damage.
How to Protect Makeup in a Hot Car?
Knowing that heat is the enemy of makeup, let’s explore some practical strategies to protect your precious cosmetics when you’re on the go.
Use a Cooler Bag
A small, insulated cooler bag can be a lifesaver for your makeup. These bags are designed to keep food and drinks cold, but they work equally well for temperature-sensitive cosmetics.
- Tip: Place a small ice pack inside the cooler bag to maintain a cool temperature. Just be sure to wrap the ice pack in a cloth or paper towel to prevent condensation from damaging your makeup.
Park in the Shade
This might seem obvious, but it’s worth emphasizing. Whenever possible, park your car in a shaded area, such as under a tree or in a parking garage. This can significantly reduce the interior temperature of your car.
Use a Sunshade
A windshield sunshade can help reflect sunlight and reduce the greenhouse effect inside your car.
- Tip: Look for a sunshade with a reflective, silvered surface for maximum effectiveness.
Store Makeup in the Glove Compartment or Center Console
These areas tend to stay slightly cooler than the dashboard or seats, which are directly exposed to sunlight.
- Tip: Wrap your makeup bag in a light-colored cloth for an extra layer of insulation.
Crack the Windows
Slightly opening your car windows can improve ventilation and help prevent extreme heat buildup.
- Caution: Only do this if it’s safe and secure to leave your windows slightly open.
Avoid Leaving Makeup in the Car for Extended Periods
This is the most effective way to protect your makeup. If you know you’ll be away from your car for a while, take your makeup bag with you.
How to Create a Car-Friendly Makeup Kit?
Sometimes, despite your best efforts, you might need to leave some makeup in the car. In these cases, it’s helpful to have a separate, car-friendly makeup kit with products that are more heat-resistant.
Choose Powder-Based Products
Powders are generally more stable in heat than creams or liquids. Opt for powder foundation, blush, and eyeshadow.
Consider Mineral Makeup
Mineral makeup often contains fewer waxes and oils, making it less prone to melting.
Use Long-Wearing Formulas
Long-wearing or waterproof products are typically formulated to withstand heat and humidity.
Carry Blotting Papers
These are great for touch-ups and can help absorb excess oil without adding more product to your face.
Keep a Setting Spray Handy
A setting spray can help lock your makeup in place and increase its resistance to heat and sweat.
Store in a Small, Opaque Bag
A small, opaque bag will provide an extra layer of protection from light and heat.
How to Salvage Melted Makeup?
Accidents happen. If you find your makeup has melted, don’t despair! Here are some techniques that might help salvage your products:
Lipstick
- Refrigerate: Place the melted lipstick in the refrigerator for a few hours to solidify.
- Reshape: If the lipstick is misshapen but not completely liquefied, you might be able to carefully reshape it with a clean spatula or your finger once it’s cooled.
- Repot: If the lipstick is beyond reshaping, you can scoop it out and transfer it to a small, clean container. You can then apply it with a lip brush.
Cream Products
- Mix: If a cream product has separated, try gently mixing it with a clean spatula or toothpick.
- Refrigerate: Cooling the product can sometimes help restore its consistency.
Pencil Products
- Sharpen: If a pencil has softened, try sharpening it to remove the melted portion.
- Refrigerate: Placing the pencil in the fridge for a short time can help firm it up.
Liquid Products
- Shake: If a liquid product has separated, try shaking it vigorously to recombine the ingredients.
- Test: Unfortunately, if a liquid product’s texture or color has significantly changed, it might be beyond saving. Test it on a small area of your skin to see if it’s still usable.
Powder Products
- Press: If a powder product has cracked, you can try pressing it back together using a clean spoon or your finger.
- Repot: If the powder is severely damaged, you can crush it into a fine powder and use it as a loose powder.
Can I Prevent My Makeup From Melting in My Car?
Absolutely! Prevention is always better than cure, especially when it comes to protecting your makeup from the ravages of heat. Here’s a recap of the best preventive measures:
Don’t Leave Makeup in the Car
This is the most foolproof method. If you can, always take your makeup bag with you when you leave your car, especially during hot weather.
Park Strategically
Choose shaded parking spots whenever possible. If a parking garage is available, opt for that over an open-air lot.
Use Sun Protection
Invest in a good quality windshield sunshade and consider using window tinting to reduce the amount of sunlight entering your car.
Create a Barrier
Use a cooler bag or insulated pouch, even if you don’t have an ice pack. This will provide an extra layer of protection against heat.
Choose Heat-Resistant Products
If you must leave some makeup in the car, opt for powder-based, long-wearing, or mineral formulas, which tend to be more heat-stable.
