Patch Testing Your Self Tanner: Why It Matters & How to Do It
When you’re excited to try a new self tanning product, it’s tempting to jump straight in. However, taking just a few minutes to carry out a patch test is one of the most important steps in your tanning routine.
At Lash Out, we want every customer to enjoy a beautiful, confidence-boosting glow safely. While reactions to self tanning products are uncommon, everyone’s skin is unique, which is why we recommend patch testing before using any new cosmetic product.
Whether you’re a first-time self tanner or you’re trying a new formula for the first time, this guide explains everything you need to know.
What Is a Patch Test?
A patch test is a simple way of checking how your skin reacts to a product before applying it over a larger area of your body.
It involves applying a small amount of product to one discreet area of skin and leaving it for the recommended time before checking for any signs of irritation.
Although most people experience no problems, a patch test gives you peace of mind and helps you use your products with confidence.
Why Should You Patch Test Self Tan?
Self tanning products contain carefully selected cosmetic ingredients that work together to create your beautiful bronzed glow.
Even if you’ve used self tan for years, every formula is slightly different.
Patch testing helps you:
- Check your skin’s compatibility with a new product.
- Reduce the risk of a reaction over a larger area.
- Feel more confident before full application.
- Become familiar with the product’s colour development.
- See how the shade looks against your natural skin tone.
It’s a quick step that can save you time and provide reassurance before tanning.
Who Should Always Carry Out a Patch Test?
We recommend patch testing for everyone, but it’s especially important if you:
- Have sensitive skin.
- Have eczema or dry skin.
- Have experienced reactions to cosmetics before.
- Are using a Lash Out tanning product for the first time.
- Haven’t used self tan for several months.
- Are trying a different fragrance or formula.
Even if you’ve previously used one tanning product, it’s good practice to patch test whenever trying something new.
How to Patch Test Your Self Tanner
Patch testing only takes a few minutes.
Step 1
Choose a small, discreet area of skin.
Good locations include:
- Inside your elbow.
- Inside your wrist.
- Behind your knee.
These areas are easy to monitor over the next 24 hours.
Step 2
Make sure the area is clean, dry and free from moisturiser, oils or perfume.
Step 3
Apply a small amount of tanning mousse using clean fingertips or a tanning mitt.
Blend it exactly as you would during a full application.
Step 4
Allow the product to develop according to the product instructions.
For Dance Dark Overnight Tanning Mousse, allow at least 8 hours before rinsing.
Step 5
After rinsing, monitor the area for approximately 24 hours.
If your skin remains comfortable with no unusual redness, swelling or irritation, you can confidently proceed with your full-body application.
What Should You Look For?
A successful patch test means your skin feels normal throughout the testing period.
If you notice:
- Persistent redness
- Swelling
- Itching
- Burning
- A rash
do not continue using the product. Wash the area thoroughly and seek advice from a healthcare professional if symptoms persist.
Is DHA Safe?
The active tanning ingredient used in self tanners is DHA (Dihydroxyacetone).
DHA works only on the outermost layer of dead skin cells, creating a bronzed appearance without exposure to UV rays.
It has been widely used in self tanning products for decades and is considered safe for cosmetic use when used as directed.

Frequently Asked Questions
Do I need to patch test every time I tan?
No. Once you’ve safely used the same product before, you generally don’t need to repeat the test unless the formulation changes or you develop new skin sensitivities.
Can I patch test multiple products?
Yes. Just apply each product to a different area of skin so you can clearly identify which one you’re testing.
What if I forget to patch test?
If you’re using a new tanning product, it’s always safer to wait and complete a patch test before full application.
Can I patch test on my hand?
It’s better to use a discreet area such as the inside of your elbow or wrist, where your skin is more representative of the rest of your body.
Is patch testing only for sensitive skin?
No. Patch testing is recommended for everyone because every person’s skin is different.
