Louis 16 Men's Delay Spray Long-Lasting Spray to Extend Sexual Intercourse Time is a topical long-lasting liquid, featuring a plant-based formula and dual functions of lubrication and arousal enhancement. This article, from a pharmacist's perspective, breaks down the onset principles, ingredient characteristics, correct usage, and key pitfalls to avoid when purchasing such products, helping adult men determine whether they are suitable and how to use them safely.
Louis 16 Men's Delay Spray Long-Lasting Spray for Extending Sexual Intercourse Time is essentially a topical endurance liquid. Its core idea is not complicated—by applying it locally to the penis, it temporarily reduces the sensitivity of the nerve endings in the glans and coronary sulcus, thereby delaying the arrival of the ejaculation reflex. Unlike oral products, it does not take the route of systemic absorption, so it acts quickly and has localized effects, which is also why many people choose topical endurance liquids.
How Topical Endurance Liquids Work

Ejaculation is a neural reflex process. When local stimulation accumulates to a certain threshold, the ejaculation center in the spinal cord issues a command. The action point of topical endurance liquids is at the starting end of this reflex arc: reducing local sensory input so that the threshold is reached more slowly.
According to the product instructions, Louis 16 uses a spray design, and each bottle can be used about 40 times. The formula is labeled as pure natural plant ingredients and also provides a lubricating effect. It should be noted that the onset time of topical products is greatly related to individual skin absorption capacity. Some people feel it in 10 minutes, while others need 20 minutes. This is a normal difference.
Ingredient Analysis: What the Plant Formula Is Doing
Common plant ingredients in topical delay products include extracts of clove, cnidium, cinnamon, and so on. Their directions of action are roughly as follows:
Compared with chemical anesthetic products containing lidocaine and benzocaine, plant formulas are characterized by mild action and lighter numbness. But the trade-off is that they may act more slowly, and the strength of the effect is not as stable as chemical anesthetics. If you have used products containing anesthetics before and felt they were "too numb," plant-based types may be more suitable; conversely, if you are pursuing strong effects, this type of product may not be enough.
How to Use: Timing, Dosage, Cleaning

According to the product instructions, the usage of Louis 16 is:
1. Before use, clean the glans and coronary sulcus area, then dry
2. First spray a small amount onto the fingers, apply to the penile sulcus and base, avoiding the urethral opening
3. After about 5 seconds, put on underwear to avoid wasting the liquid
4. Wait 10-20 minutes to let the ingredients fully absorb before intercourse

Horizontal Comparison of Similar Products
Topical endurance liquids on the market are roughly divided into three categories. When purchasing, first figure out which type you want:
Taking Louis 16 as an example, its positioning leans toward the plant-based mild type and also has a lubricating function, making it suitable for adult men who want a natural enhancement and do not want to completely lose sensation. If you value onset speed more, products such as German Black King Kong Endurance Liquid may be more suitable; if you prefer an imported established brand, EROS Ilusi 101 is also a common option.
Three tips to avoid pitfalls when purchasing:
1. Check the ingredient list and avoid plant extracts you are allergic to
2. Check the specifications and number of uses. About 40 uses for 10ml is a normal level. Be cautious of claims that "one bottle lasts half a year"
3. Check whether there is anti-counterfeiting verification. There are many counterfeit topical products, and this point is more important than price
Safety Warning: Who Should Not Use It

Although topical endurance liquids do not undergo systemic absorption, there are still contraindications:
In terms of side effects, clinically common ones are local burning sensation, mild numbness, or redness, usually relieved after cleaning. If persistent stinging, edema, or spreading rash occurs, stop using it and seek medical attention.
There is also an easily overlooked point: if after spraying you find there is completely no sensation, or even that erection is affected, it means the dosage was excessive, and it should be halved next time. Long-term reliance on high doses and making it numb to the point of no sensation every time may instead affect the normal ejaculation reflex.
Common Questions
Q: How long can Louis 16 delay spray last?
A: According to the product instructions, a single application lasts about 20-30 minutes. The actual duration is affected by dosage, individual absorption, and stimulation intensity.
Q: Will my partner feel anything after I use it?
A: The product instructions mention that it can enhance female pleasure, but the main mechanism is lubrication and prolonging time. If you are worried about ingredient transfer, simply clean before intercourse.
Q: Can it be used every day?
A: Not recommended. Topical endurance liquids are temporary aids, not daily care products. Frequent use may make the local skin tolerant and reduce the effect.
Q: Can it be used together with oral medication?
A: It is not recommended to stack them on your own. Oral erection aids and topical delay products have different mechanisms of action, and using them at the same time may make the body's reactions difficult to judge. Consult a doctor.
Q: Why did it have no effect the first time I used it?
A: It may be due to insufficient dosage, not enough waiting time, or slower personal skin absorption. You can first read Things to Note When Using a Delay Spray for the First Time and adjust according to the steps.
Pharmacist's Advice
Louis 16 Men's Delay Spray Long-Lasting Spray for Extending Sexual Intercourse Time belongs to the plant-based mild type among topical endurance liquids, suitable for adult men who want to prolong sexual intercourse time but do not want complete numbness. The core usage is just three points: 10-20 minutes in advance, a small amount the first time, and avoiding the urethral opening. When purchasing, prioritize ingredients and anti-counterfeiting rather than only looking at price.
If you have a history of skin sensitivity, are taking medication, or have used it several times with unsatisfactory results, it is recommended to first seek evaluation from a doctor or pharmacist rather than increasing the dosage and forcing it yourself.
help常見問題
Q1.How long in advance should Louis 16 delay spray be used for the best effect?
According to the product instructions, apply 10-20 minutes in advance to allow the ingredients to fully absorb. For first-time use, it is recommended to apply 20 minutes in advance to observe your own absorption speed, and then adjust according to your actual response. After spraying, you can put on underwear after 5 seconds without affecting the effect.
Q2.Why do delay sprays have no effect after use?
There are two situations: one is that too much was used, causing excessive numbness, so use half the amount next time; the other is that the waiting time was not long enough and the ingredients were not fully absorbed. If there is still no sensation after adjustment, it may be due to individual differences in absorption, and it is recommended to switch to another type or consult a pharmacist.
Q3.Do external long-lasting liquids help with erections?
No. External long-lasting liquids address the issue of sensitivity, not erectile hardness. If you have difficulty achieving an erection, this type of product is ineffective, and erectile function needs to be evaluated. The product instructions also state that it is ineffective for patients with impotence.
Q4.Can delay sprays be used every day? Will they cause dependence?
It is not recommended to use it every day. It is a temporary auxiliary product, and frequent use may cause local skin tolerance, gradually reducing the effect. There is currently no evidence that external delay sprays cause physiological dependence, but psychological dependence is worth noting.
Q5.How can you tell whether a delay spray you bought is genuine?
Prioritize products with an anti-counterfeiting verification code, and scan the code to verify immediately after receiving it. Check whether the packaging printing is clear and whether the batch number and shelf life are complete. Be cautious of products priced significantly below the average market price; external products have a relatively high risk of counterfeiting.
