How to apply a self-tanner?

Self-tanning products work like a dye: they chemically react with and tint the dead cells on the skin's surface to give it that much-desired tanned colour. As a result, before applying a self-tanner, it is recommended to use an exfoliating product (peeling, grain scrub, exfoliating glove, etc.) to help remove dead skin cells and ingrown hairs, which contribute to uneven tanning . Indeed, skin that has not been exfoliated beforehand will make the application of the self-tanner less easy and the result would then not be uniform.

This action is particularly crucial around various joints (elbows and knees), where the skin is thicker, to prevent self-tanning product from accumulating in these areas. Moreover, considering that the duration of the tan also depends on the renewal of skin cells, it is better to exfoliate to maintain a longer-lasting tan.

It is thus recommended toperform an exfoliation a few days before application to achieve smoother skin, thereby optimising the product's performance and allowing the self-tanner to adhere better to the skin. However, it is important to note that certain treatments (AHA, BHA, retinol, grain scrubs, etc.) should not be used just before applying a self-tanning product and certainly not after, to avoid affecting the colour and reducing the lifespan of the tan.

Shaving is a form of mild physical exfoliation of the skin. Aside from removing "unwanted" hair, this means it can also "scrape off" the top layer of dead skin cells, much like a conventional exfoliation. However, the traditional active ingredients in self-tanning products (erythrulose, DHA, etc.) interact with the corneocytes located in the horny layer of the epidermis to provide a bright and natural tan.

Thus, if you shave or wax, do so at least 24 hours prior to the application of fake tan. Also, try to limit shaving sessions when you are wearing self-tanner for a long-lasting and even tan. The same applies to hair removal, whether it's with wax, threading, an electric epilator or hair removal cream.

Conversely, can we apply self-tanner to hairy areas?

Some believe that hair can interfere and compromise the achievement of a natural and even fake tan. However, it is not necessary to shave or wax. For a better result, opt for the use of an applicator mitt.

Elbows, ankles, knees... these dry areas of the body need to be particularly well moisturised to prevent self-tanning products from concentrating too much in these creases, causing the fake tan to appear darker than elsewhere, resulting in a less natural look. However, on the day of applying the self-tanner, avoid moisturising your skin. Indeed, the application of a moisturising cream can create a barrier that affects how the active self-tanning ingredients react with skin cells, thus preventing the self-tanner from fully and evenly developing.

In addition to self-tanning agents, our body self-tanning gel contains aloe vera (INCI: Aloe Barbadensis Leaf Juice Powder) for its moisturising properties and turmeric extract (INCI: Curcuma Longa Root Extract) for its antioxidant virtues.

Although DHA and erythrulose are generally safe, it is recommended to test a small amount of the self-tanner on an area of your body before a broader application. If side effects such as redness or irritation occur, immediately cease using the product.

After preparing your skin, you can now apply a self-tanner to your clean and completely dry skin. It is advisable to apply the self-tanner in the evening, as it takes about six hours to see the result. Although there are different ways to apply a self-tanner, including doing it bare-handed, using a velvety applicator mitt transforms the tanning process. Efficient and practical, it allows for covering larger body areas more quickly and achieving a more natural result. It also helps to absorb any excess product, thus reducing the risk of a uneven finish in case of heavy-handed application.

If you use your hands to apply your self-tanner, thoroughly wash your hands and nails with water and soap to prevent your palms from turning orange.

Apply a "generous" amount of product onto the glove, and completely and evenly cover the skin without rubbing. Start from the lower part of the body or face and gradually move upwards. Distribute the product through light and long vertical movements, and by sections (legs > arms > chest > back). Remember to spread the self-tanner over all exposed areas, extending it to your wrists, the backs of your hands, your ankles, and your feet for a more natural effect.

Our self-tanning products that dry quickly are safe from transferring onto clothes and pillows. However, when you apply the body self-tanning gel, wait at least 10 to 20 minutes before dressing.

To maintain a fresh tan for as long as possible, hydrate daily. Indeed, hydration is crucial for a more even and long-lasting result, preventing the skin from drying out and flaking.

Although it can mimic the sun-kissed complexion of natural melanin tanning, theself-tanner alone provides no sun protection. A study has shown that the tan achieved with DHA only provides a sun protection factor (SPF) of 3, which is far from sufficient. To protect the skin from the harmful impact of UVA and UVB rays, apply a broad-spectrum sunscreen every day with an SPF of 30 or more.

All these tips can assist you in achieving a natural-looking tan. However, this does not guarantee a flawless result. Uneven patches may still appear. Self-tanning requires practice to master.
