Tanning with vegetable oils - is it enough?
Natural sun protection has become a hot topic in recent years. Some people seek simpler cosmetic ingredients, others want to better understand what they use, and some simply want to try making their own summer skin care at home.
It is at this time that information often appears about plant oils and their supposed ability to protect skin from the sun. Most commonly, raspberry seed oil , carrot oil , coconut oil , or shea butter are discussed.
However, there are many inaccuracies regarding the SPF of plant oils. Values differ among articles, some are based on outdated studies, and others are merely repeated internet shortcuts lacking broader context.
That doesn't mean plant oils have no place in summer skin care. It's just important to understand their limitations and use them with reasonable expectations.
Why is natural sun protection such a popular topic
It makes sense. Plant oils are familiar to people, are commonly used in cosmetics, and many of them provide nourishment, soften the skin, and help it cope with summer stress.
There is also a growing tendency to replace conventional sunscreens with 100% natural alternatives. But this is where caution is necessary.
Current knowledge does not confirm that plant oils alone can reliably substitute for standard sun protection. Some oils may partially absorb UVB rays, but generally, they don’t provide stable or proven protection in the same measure as you would expect from a regular sun product.
What is SPF
SPF, or Sun Protection Factor, denotes the level of protection against UVB radiation, the type that causes sunburn.
For example, if your skin would burn in 20 minutes without protection, a product with SPF 15 theoretically increases that time about fifteen times.
In practice, however, this depends on the intensity of the sun, amount of product applied, sweating, swimming, skin sensitivity, and regular reapplication.
The difference between UVA and UVB radiation
For sunbathing, it's important to consider both types of UV radiation. UVB is mainly associated with sunburn. UVA penetrates deeper into the skin and contributes to premature aging.
Most plant oils provide limited protection from UVB rays, while their effectiveness against UVA rays is insufficient or unclear.
Why is it difficult to determine SPF for plant oils
SPF in conventional sun products is measured in labs under tightly defined conditions. For plant oils, the situation is trickier.
- quality of raw material,
- processing method,
- oxidation,
- concentration,
- storage,
- oil age.
Therefore, SPF numbers for plant oils should be taken as indicative, not as a guarantee of protection.
The most commonly used oils for natural sun care
Raspberry Seed Oil
Raspberry Seed Oil is one of the most frequently cited oils in connection with natural sun care. Extremely high SPF values are often claimed, but these have not been consistently confirmed.
In cosmetics, it is used for caring for stressed skin and can be a nice part of summer oil blends or after-sun treatments.
Carrot Oil
When it comes to carrot oil , the term is often confusing. Sometimes it refers to carrot seed oil, other times to a root macerate.
Carrot oils are used in cosmetics to care for sun-exposed skin and as a part of summer formulations. When working with essential oils, always stick to recommended dosages and do a patch test.
Coconut Oil and Shea Butter
Coconut Oil and Shea Butter are staples in homemade cosmetics. They nourish the skin well, help prevent dryness, and are often used in body butters or after-sun balms.
Their SPF is quite low, so they are not enough for standalone sun protection during prolonged exposure.
Avocado and Olive Oil
Avocado Oil and Olive Oil are also associated with natural skin protection.
Both oils are rich, contain fatty acids, and are used in many cosmetic recipes.
They have a place as nourishing ingredients in summer cosmetics, but not as a full replacement for sunscreen.
How to use plant oils safely
A more sensible way is to use plant oils as part of a broader skincare regimen, not as the sole protection.
- combine with mineral UV filters,
- apply after sun exposure,
- protect skin physically as well,
- do not overestimate indicative SPF values.
Storage and oxidation of oils
Plant oils are sensitive to light, heat, and air. Improper storage causes them to oxidize, alters their properties, and gradually reduces quality.
- store them in well-sealed bottles,
- keep away from direct light,
- store in cool places,
- do not use old or rancid oils.
Mineral UV filters
If you want to create your own summer cosmetics, a safer way is to combine plant oils with mineral UV filters, such as zinc oxide or titanium dioxide . However, even with homemade production, keep in mind that you cannot precisely determine the final SPF without laboratory testing.
What to take away from this
Plant oils can be a very pleasant part of summer skin care. They help with nourishment, hydration, and comfort for sun-stressed skin.
However, it is wise not to overestimate their SPF and not rely on them as your only protection.
If you want to try your own summer care, start simple and in small quantities. You can find raw ingredients, recipes, and tools for homemade cosmetics at Ekokoza. And if you are unsure about choosing or procedures, contact us.
