Myth or reality: preparing your skin for the sun – a useful habit or a myth?

Yes… provided we clearly define what we mean by ‘preparing’. 

• If the aim is to protect the skin from the sun, the answer is no. 

• On the other hand, if we’re talking about helping the skin cope better with UV-induced oxidative stress, the verdict becomes more nuanced. Several studies show that certain carotenoids, taken over several weeks, can modulate the skin’s response to UV radiation. For example, a randomised trial observed an improvement in certain parameters related to UVA-induced pigmentation after 12 weeks of supplementation (1). Recent reviews confirm this trend: certain supplements (carotenoids, polyphenols, botanical extracts) show potential as oral photoprotection. However, at this stage, the evidence remains mixed and still limited (2). 

Preparing the skin may therefore be worthwhile as part of a holistic approach, but it remains a complementary strategy rather than a form of protection in its own right (2).

1. The first limitation concerns timing. Studies show effects after several weeks, not after a few days. A last-minute treatment is therefore unlikely to be effective (1).

2. The second limitation lies in the over-interpretation of the results. An improvement in certain biological markers does not mean you won’t get sunburnt, nor does it guarantee protection against skin damage.

3. The third limitation, linked to the previous one, is probably the most significant: a false sense of security. Feeling prepared may lead to greater exposure to the sun or to neglecting standard protective measures. However, prevention relies on a set of complementary measures, of which sun protection remains central (5).

4. Finally, this approach does not take individual factors into account: skin type, skin sensitivity, medical history or photosensitising treatments.

Before looking into preparing your skin, it is worth revisiting what research considers to be truly effective in limiting the impact of UV rays. Rather than relying on a single approach, sun protection is based on a combination of complementary measures, some of which take effect beforehand, whilst others act at the time of exposure. 

Myth or reality?

Preparing your skin for the sun is therefore neither a myth nor a miracle cure. It is based on a sound intuition: that you can support your skin in advance to help it cope better with intense environmental stress. And, on this point, the scientific literature provides some interesting insights, particularly regarding carotenoids and antioxidants (2). However, this idea becomes misleading when interpreted as a form of ‘protection’: no preparation, however rigorous, can replace external photoprotection mechanisms.

What sun preparation actually achieves

Under certain conditions, particularly when started several weeks before exposure, sun preparation can help to strengthen certain skin defence mechanisms. This is mainly achieved by supporting the antioxidant systems, which help the skin to better manage some of the oxidative stress induced by UV radiation (1)(2). It can also help the skin adapt more gradually to exposure, particularly when returning to the sun after winter. It is therefore less about preparing the skin to tan and more about better supporting the skin in the face of a harsh environment, in line with a holistic approach to skincare.

What it does not guarantee

This point is essential, and often misunderstood. Preparing the skin for the sun does not protect against sunburn, skin burns, or the cumulative effects of ultraviolet radiation. Nor does it prevent photoageing, pigmentation spots or even DNA damage linked to excessive exposure (5). Above all, it does not significantly alter the risk in the event of prolonged exposure without suitable protection. It is precisely this confusion that fuels the misconception that a single product is sufficient, whilst the literature emphasises the need to combine several forms of protection (2)(5).

Food for thought

What if the question were not “how do we prepare our skin for the sun?”, but rather: “why do we seek to compensate for exposure that we could, in part, avoid?” The notion of preparation can sometimes reflect an implicit desire to expose ourselves to more sun, based on the idea that the skin would be better equipped. However, science does not support this view. On the contrary, it urges us to rethink our relationship with the sun by prioritising gradual and sensible exposure, fully incorporating protective measures, and viewing supplements and skincare products as supports, not as solutions. Preparing one’s skin, in this context, becomes a logical step. But to believe that this preparation is sufficient in itself is to harbour an illusion. 

Changing our approach to tanning means understanding that it is nothing more than a protective mechanism against UV rays. As some UV rays are classified as carcinogenic, deliberately tanning is tantamount to exposing ourselves to foreseeable damage to the DNA of our cells, which can lead to skin cancer. Deliberate tanning is therefore an activity to be avoided. If you want a healthy glow, self-tanning is the way to go.

Organic Urucum dietary supplement

Rich in carotenoids, particularly bixin, Urucum is traditionally used in seasonal skincare routines. This plant-based microalgae is prized for its natural pigment content, which helps to enhance the colour and radiance of the complexion. As part of a course of treatment, Urucum forms part of a holistic approach aimed at supporting the skin ahead of periods of sun exposure, particularly as part of a beauty routine designed to promote a healthy glow. It is not a sunscreen and does not replace sun protection measures. To maximise the effectiveness of Urucum, it is best to start the course several weeks before sun exposure, but it is never too late. Take 2 to 4 tablets a day, swallowed with a large glass of water, until the jar is finished. You may continue taking it for the duration of your sun exposure. Not recommended for pregnant or breastfeeding women, or for smokers. Do not use if you are allergic to annatto (roucou).

Rather than seeking to prepare the skin for sun exposure, at Aroma-Zone we favour an approach that aims to preserve its long-term health. This involves simple steps: limiting UV exposure, protecting yourself effectively when it is unavoidable, and avoiding the pursuit of a tan as a goal in itself. In line with this, we prefer to help you achieve a healthy glow without the sun, using suitable skincare products that respect the skin’s natural balance. This approach allows you to combine a radiant complexion with safety, without compromising your health.

“What is the difference between strengthening the skin and protecting it effectively? The question reveals an ambivalent attitude towards the sun. UV radiation is classified as a definite carcinogen. Tanning is a defence mechanism against this damage. It would therefore make sense to adopt a strategy of avoiding UV rays, and thus tanning. Yet many people still choose to sunbathe and would like to do so whilst minimising the risks… This is completely illogical. Given the risk of cancer, people with fair skin should avoid exposure when the UV index exceeds 3, and should wear protective clothing and apply sun cream to exposed areas when exposure is unavoidable. If you enjoy the sensation of the sun on bare skin, without wanting to tan, keep an eye on the UV index – and generally speaking, the lights are green before 10 am and after 5 pm in our part of the world!"

Dr Reyhan Amode, dermatologist and member of the Aroma-Zone College of Dermatologists

Preparing your skin for the sun should never lead to deliberately increasing the length of time you spend in the sun. Targeted dietary supplements and antioxidants are no substitute for appropriate sun protection or physical measures (clothing, shade). Extra caution is recommended for fair or sensitive skin, or in the case of treatment that causes photosensitivity (5).

Rather than trying to prepare your skin as you might prepare a plot of land, it is more accurate to think in terms of gradual adaptation. The skin is not a material that you strengthen once before exposure: it is a living organ that reacts continuously to its environment. What makes the difference, therefore, is not just what you do before summer, but how you expose your skin over time. In practical terms, prioritising short, repeated and gradual exposure remains one of the most effective ways to support your skin. This approach allows for gradual adaptation, which is very different from sudden and prolonged exposure.
