How Does A Self-Tanner Work? In short, a self-tanner works by containing an active ingredient called dihydroxyacetone (DHA), derived from sugar cane, that reacts with the amino acids in the dead skin cells on the surface of the skin to darken it, mimicking a tan.
The darkening effect is only cosmetic and occurs on the surface of the skin. It does not provide sun protection and may cause skin irritation or an allergic reaction for some individuals. It is important to choose a product suitable for your skin type and follow instructions carefully.
Detailed Guide On How a Self-Tanner Work
A comprehensive guide on how a self-tanner works is the following:
Application of self-tanner to skin
Before applying a self-tanner, it’s necessary to exfoliate the skin to remove dead skin cells and ensure an even application. This can be done using a gentle scrub or exfoliating mitt.
When applying self-tanner, it’s best to use gloves or a mitt to avoid streaks and ensure even coverage. Apply the product evenly to the skin, starting from the ankles and working your way up.
Once the self-tanner has been applied, allow it to dry completely before getting dressed or going to bed. This typically takes 10-15 minutes, but the exact time may vary depending on the product.
To achieve a deeper color, you can reapply self-tanner as desired. It’s essential to wait until the previous application has dried before applying additional layers.
The reaction of DHA with amino acids in dead skin cells
The active ingredient in self-tanners is called Dihydroxyacetone (DHA), which reacts with the amino acids in the dead skin cells on the surface of the skin.
The reaction produces a pigment called melanoidins, which gives the skin a darkened appearance.
It’s crucial to note that the reaction only occurs on the surface of the skin and does not affect living skin cells. The color produced by a self-tanner is cosmetic and temporary.
The resulting darkening effect mimics a tan
The darkening effect produced by the reaction of DHA with the amino acids in dead skin cells mimics the appearance of a natural tan.
The color produced by a self-tanner typically lasts from 5 to 7 days, depending on the product and individual skin type. To maintain the color, reapply the self-tanner as needed and avoid exfoliating the skin.
Regular maintenance of the self-tan is necessary to maintain the desired color.
The time frame for the reaction to occur
The time frame for the reaction to occur depends on several factors, including the type of self-tanner, the skin type, and the desired color.
Some self-tanners produce results within hours of application, while others may take several hours or overnight to develop. The color will continue to darken over the next 24 to 48 hours after application.
Explanation of darkening effect as cosmetic and not a chemical reaction
The darkening effect produced by a self-tanner is a cosmetic change and not a chemical reaction.
The cosmetic change is temporary and will gradually fade as the dead skin cells naturally exfoliate.
It’s key to understand that a self-tanner does not provide sun protection and that a broad-spectrum sunscreen with a high SPF rating should be used to protect the skin from the sun’s harmful UV rays.
Choosing the Right Self-Tanner for You
With so many different self-tanners on the market, it can be difficult to choose the right product for your needs. To help you find the right self-tanner for you, consider the following factors:
- Skin type: If you have sensitive skin, look for a self-tanner that is specifically formulated for sensitive skin, as these products will be gentler and less likely to cause irritation.
- Formula: Self-tanners come in a variety of formulas, including lotions, sprays, and mousses. Consider your personal preference and how you like to apply products to your skin when choosing a formula.
- Level of tan: Different self-tanners will produce different levels of tan, so consider the level of tan that you’re looking for when choosing a product.
Achieving the Perfect Self-Tan
Achieving the perfect self-tan involves following certain steps to ensure an even and natural-looking result:
- Preparation: Exfoliate the skin thoroughly to remove any dead skin cells, which can affect the evenness of the tan. Moisturize dry areas such as elbows, knees, and ankles to prevent them from absorbing too much tanner.
- Choice of tanning product: Choose a self-tanning product that best suits your skin tone and type. Products come in different forms, such as sprays, lotions, or mousses, and can vary in intensity.
- Application: Apply the self-tanner evenly, using a mitt to help spread the product and avoid streaks. Pay extra attention to areas that are prone to absorbing more tanner, such as the hands, feet, and face.
- Wait time: Follow the product’s instructions for the recommended wait time before dressing and avoid sweating or getting wet.
- Maintenance: To maintain the tan, reapply the self-tanner every few days, and use a gradual tanning moisturizer to extend the life of the tan.
- After-care: Hydrate the skin regularly to prevent the tan from fading too quickly. Avoid exfoliating or using harsh skincare products that can strip the skin of the tan.
Following these steps and using a high-quality self-tanning product can help you achieve a natural and even self-tan.
The Bottom Line
Self-tanners are a safe and effective way to achieve a sun-kissed glow without exposing yourself to the harmful effects of the sun. By understanding how self-tanners work and how to get the best results from these products, you can achieve a beautiful, natural-looking tan that will have you looking and feeling your best.
