Naturally prepare your skin for the sun: your guide to a gentle summer approach

When the days get longer and the first outdoor terraces fill up, your skin isn't always ready to go from winter grey to May UV. Naturally preparing your skin for the sun doesn't mean slathering on self-tanner or using complicated skincare routines. It means giving it back the comfort, suppleness, and hydration it lost during winter, so it can welcome the sun's rays without feeling tight, red, or dehydrated. In this guide, you'll see why this preparation really makes a difference, what simple steps to adopt from May onwards, which vegetable oils to choose based on your skin type, and how basic. makes products in Lausanne that align with this philosophy: few, well-chosen ingredients, no smoke and mirrors. The goal isn't to tan more, it's to better enjoy summer.

Why naturally preparing your skin for the sun changes everything

Skin emerging from winter is thinner, drier, and less elastic than in spring. According to a review published by the American Academy of Dermatology, the skin barrier loses up to 25% of its water content during the cold months, and this dehydration persists for several weeks after heating ends. The result: when you expose yourself to the sun without transition, your skin reacts faster. Increased dryness, redness, feelings of tightness, or even small areas of flaking: these are not signals to ignore.

Naturally preparing your skin for the sun means giving it the conditions to absorb light without suffering. This involves three simple things: deep rehydration, strengthening the hydrolipidic film, and reintroducing essential fatty acids. Properly prepared skin tans more evenly, retains its glow longer, and better resists micro-aggressions related to heat (chlorine, salt, friction from light clothing).

Warning: preparation does not mean protection. Cosmetic preparation NEVER replaces adequate sun protection. It prepares the ground, that's all. For UV protection, we are talking about a different type of product, chosen according to your phototype and exposure duration.

Some figures to put it in context

• Hydrated skin loses up to 40% less water during moderate sun exposure compared to dehydrated skin (source: International Journal of Cosmetic Science).
• 4 to 6 weeks: this is the average time needed to observe a real change in the quality of the skin barrier after introducing vegetable oils into a routine.
• 70% of respondents in a 2024 Mintel study say they experience skin discomfort during the spring-summer transition.
• Cold-pressed vegetable oils retain up to 95% of their unsaturated fatty acids, compared to only 60% for refined oils.

The 3 pillars of skin ready for the sun

Good preparation rests on three main axes. No need to stack ten products: aiming accurately is largely sufficient. Here's how to build a simple, natural, and effective routine, to start 4 to 6 weeks before the first serious exposures.

1. Deep rehydration

Hydration first comes from within (water, water-rich fruits and vegetables, infusions) and then through the stratum corneum. At this stage, we aim to boost water retention in the epidermis. Organic aloe vera gel is an excellent starting point: it penetrates quickly, leaves no greasy film, and provides water and polysaccharides that retain moisture. Applied in the morning to slightly damp skin, it perfectly prepares the skin for the next steps.

2. Restoring the hydrolipidic film

Comfortable skin in the sun is skin whose hydrolipidic film functions correctly. This natural film, composed of sebum and sweat, acts as a barrier. To support it, we rely on cold-pressed vegetable oils, rich in fatty acids (omega 6, omega 9) and fat-soluble vitamins. One to two drops in the evening are enough — no need to apply a thick layer.

3. Providing antioxidants

UV rays generate free radicals that accelerate skin aging. Certain vegetable oils (argan, macadamia, apricot) are naturally rich in vitamin E and carotenoids, which help the skin better manage this aggression. This is called topical antioxidant support: it does not replace sun protection, but it intelligently complements it.

Which vegetable oils for which preparation: the table

Not all vegetable oils are equally suitable depending on your skin type. Here is a comparative table of the most relevant oils for naturally preparing your skin for the sun, based on their fatty acid composition, their comedogenic index, and their affinity with each skin type.

Vegetable oil	Ideal skin type	Comedogenic index	Key benefit for summer
Organic sweet almond oil	All skin types, including sensitive and baby skin	2 (low)	Soothes, softens, relieves tightness
Organic jojoba oil	Combination to oily	2 (low)	Regulates sebum, leaves no greasy film
Organic macadamia oil	Dry to very dry	2 (low)	Deeply nourishes, rich in palmitoleic acid
Organic apricot kernel oil	Dull, combination skin	2 (low)	Brightens, rich in carotenoids
Organic hazelnut oil	Oily, combination with imperfections	2 (low)	Tightens pores, purifying
Organic avocado oil	Dry, mature	3 (moderate)	Restorative, rich in vitamin E
Organic argan oil	Combination to mature	0 (none)	Powerful antioxidant, protective

In practice, many people alternate or mix two oils depending on the area of the face and the season. An organic sweet almond oil on the body after showering, an organic argan oil on the face in the evening: this is already a very effective routine for approaching summer.

The basic. method — preparing your skin for the sun in 4 simple steps

At basic., we manufacture our natural cosmetics in Lausanne, with short formulas (often less than 10 ingredients), PETA certified vegan, and refillable packaging designed to last. Our approach to preparing skin for the sun follows the same logic: few products, simple steps, effective results. Here's how we apply it daily.

Step 1: Hydration base with aloe vera gel

In the morning, on clean and slightly damp skin, apply a small amount of organic aloe vera gel. Its fresh texture penetrates instantly, without stickiness. This is the foundational step that prepares the skin to receive the rest of the routine.

Step 2: 2 drops of targeted vegetable oil

Choose the oil according to your skin type (see table above). A few drops are enough: warm it between your palms, then gently pat it onto your face and neck. Evening is the ideal time, as the skin naturally regenerates between 11 PM and 4 AM.

Step 3: Nourish the body after showering

After each shower, take advantage of still damp skin to apply a vegetable oil to your arms, legs, and stomach. This simple gesture helps retain water in the stratum corneum and restore suppleness to areas most exposed to the sun. Organic macadamia oil is particularly suitable here: it melts instantly, is not greasy, and deeply nourishes.

Step 4: Don't forget key areas

Three areas are systematically overlooked: the eye contour, lips, and hands. Finish with a touch of oil around the eyes (gently patting), a natural lip balm, and a small amount of hand balm. These areas are the first to show signs of skin poorly prepared for heat.

This method takes 3 minutes in the morning, 3 minutes in the evening. No miracle product, no 12-step ritual: just regularity, simple formulas, and properly made in Lausanne. This is what we call, at basic., doing a job well done.

Common mistakes to avoid when preparing your skin for the sun

The "more is better" logic doesn't work in natural cosmetics. Here are the most common mistakes we observe and how to correct them.

Mistake 1: Starting too late

Starting the day before your vacation is useless. Skin needs at least 4 to 6 weeks to absorb a new routine and restructure its hydrolipidic film. The right window to start: between late April and mid-May, which is now if you are reading this article in spring.

Mistake 2: Exfoliating just before exposure

Many believe that exfoliation prepares the skin. It's the opposite: exfoliation just before exposure weakens the skin barrier and increases sensitivity to UV. If you exfoliate, do so at least 48 hours before prolonged exposure, and no more than once a week.

Mistake 3: Confusing preparation and protection

Preparing your skin does not exempt you from using appropriate sun protection. No vegetable oil has a sufficient protection factor to replace a sunscreen. Preparation is complementary, never a substitute.

Mistake 4: Stacking products

Three well-chosen products are better than ten stacked routines. Skin needs simplicity to assimilate. As we say at basic.: few, well-chosen ingredients are already a lot. This philosophy aligns with the skinimalism trend which is gaining traction in 2026.

Mistake 5: Choosing an oil unsuited to your skin type

Oily skin will become saturated with avocado oil. Very dry skin will remain unsatisfied with hazelnut oil. The table above is there to guide you: take the time to choose.

And after exposure: extending the benefits

Preparing your skin is already half the battle. The other half is post-exposure repair. After a day in the sun, the skin needs water and soothing. Our complete guide to natural after-sun oils details the right evening gestures: lukewarm shower, fresh aloe vera gel (to keep in the fridge in summer), then nourishing oil.

FAQ — naturally preparing your skin for the sun

When should I start preparing my skin for the sun?

Ideally, you should start 4 to 6 weeks before your first prolonged sun exposures. In French-speaking Switzerland, this corresponds to late April or early May for June-July holidays. A regular routine over this period allows the skin barrier to strengthen.

Which vegetable oil should I choose to prepare my skin for the sun?

It depends on your skin type. For sensitive skin or all skin types: sweet almond oil. For combination to oily skin: jojoba or hazelnut oil. For dry skin: macadamia or avocado oil. For a universal antioxidant effect: argan oil. The table in this article details each option.

Does vegetable oil protect against UV rays?

No. No vegetable oil offers sufficient sun protection to replace a sunscreen. Cosmetic preparation enhances skin comfort and resistance, but it does not protect against UVA and UVB. For protection, a specific product with an appropriate SPF rating is necessary.

Should I exfoliate before sun exposure?

Not immediately before. Exfoliating just before exposure weakens the skin barrier and increases sensitivity. If you exfoliate, do so at least 48 hours before exposure, and no more than once a week during the summer period.

Can I apply a vegetable oil in the morning under sunscreen?

Yes, provided you leave a few minutes between the two applications. The oil penetrates quickly, and the sunscreen then acts as a protective layer. This layering works well with light oils like argan or jojoba.

How many drops of vegetable oil should I apply daily?

Two to four drops are enough for the face and neck. For the body, half a dropper per area (arms, legs) is plenty. The basic rule: if your skin is still shiny after 5 minutes, you've applied too much.

Is aloe vera gel suitable for all skin types?

Yes, organic aloe vera gel is suitable for all skin types, including the most sensitive and reactive. It is one of the most universal skincare products available. It is particularly appreciated in summer due to its freshness and non-sticky effect.

Should I continue the routine during holidays?

Yes, ideally you should maintain the routine throughout the summer, adapting it: fewer layers, more freshness. In the morning, keep the aloe vera gel and set aside overly rich oils. In the evening, return to the oil routine for repair.
