The Science Behind Self Tan

Science behind self tanWhat is DHA?

The active ingredient in most self tan is DHA (Dihydroxyacetone).

DHA is a colourless sugar that interacts with the dead cells located in the stratum corneum of the epidermis. As the sugar interacts with the dead skin cells, a colour change occurs. This change usually lasts about five to seven days from the initial application.

How does DHA work?


Caribbeantan products contain specially formulated active ingredients. One of these ingredients is DHA (Dihydroxyacetone – natural sugar cane derivative). When applied to the skin, DHA causes a chemical reaction with the skin to produce a tan much like the sun, but without the UVA and UVB damage to the skin. According to the American Academy of Dermatology, the most effective products available are sunless or self-tanning lotions that containing dihydroxyacetone (DHA) as the active ingredient.

Is it safe?

Absolutely! All Caribbeantan ingredients have been through extensive testing. Only about 1% of the population is allergic to DHA.

Can I tan naturally after applying Caribbeantan?

To avoid premature skin ageing from the sun, we recommend not going into the sun without protection on your skin.

How long does it last?

Caribbeantan lasts between 4 to 10 days, depending on your skin type and how well you maintain it.  Check out our Tanning Tips for the ways to maintain your tan.

What to consider when choosing a product?

Choosing the appropriate shade is extremely important since the skin type is extremely relevant in the tanning process. Never apply a darker shade on a fair skin. You should also consider if you prefer an instant tan or a gradual tan when selecting from our self tanning range.
