How to choose sunscreen for your skin

A sunscreen left forgotten in the drawer does not protect the skin. Therefore, knowing how to choose sunscreen is not just about looking for the highest SPF: it is about finding a comfortable formula, suitable for your routine and easy to reapply when necessary.

The choice can seem confusing amidst numbers, symbols, textures, and promises. In practice, there are few criteria that truly make a difference: protection against UVA and UVB, SPF, finish, water resistance, and compatibility with your skin. The best sunscreen is, above all, the one you will use consistently.

Key points to remember

• Choose broad-spectrum protection for both UVA and UVB.
• For daily use, SPF 30 is a starting point; SPF 50 provides an additional margin during greater exposure.
• The texture should suit your skin type and how you like to finish your routine.
• Apply a generous amount and reapply after water exposure, intense perspiration, or friction.
• Sunscreen does not replace shade, clothing, or other sensible sun exposure habits.

What to look for in a sunscreen

SPF: the number doesn't tell the whole story

SPF stands for Sun Protection Factor and refers primarily to protection against UVB rays. In simple terms, the higher the SPF, the greater the margin of protection when the product is applied in the recommended amount.

For a daily routine with regular exposure, an SPF 30 may be adequate. If you spend a lot of time outdoors, have direct exposure during commutes, engage in physical activity outside, or are looking for an extra margin, SPF 50 is generally the most practical option. SPF 50 does not allow for applying less product nor does it eliminate the need to reapply.

More important than choosing between SPF 30 and 50 is using a sufficient amount. A very thin layer significantly reduces the actual protection obtained.

UVA protection: look for broad spectrum

UVA rays are present throughout the year and pass through clouds and glass. They can contribute to visible signs of skin aging, such as changes in tone and loss of uniformity. UVB rays are more associated with redness caused by the sun.

On the packaging, look for references to UVA and UVB protection or the term “broad spectrum.” In Europe, the UVA symbol inside a circle is also a useful indicator: it means that the UVA protection meets the standard defined to be balanced with the indicated SPF.

How to choose sunscreen for your skin type

Your skin type does not determine the level of protection you need. It does, however, determine the texture and finish that will make daily application more pleasant.

Dry or dehydrated skin

A creamy or moisturizing formula may fit better into your routine. Humectant ingredients, such as glycerin or hyaluronic acid, help provide comfort to the skin's surface. If your skin tends to feel tight, a very light, alcohol-based fluid might not be the most comfortable option.

Even so, you are not required to look for a very rich sunscreen. If you already use a moisturizer you like, you might prefer a light sunscreen on top. The balance depends on the layers you use in the morning.

Oily skin or skin that gets shiny throughout the day

Fluids, gel-creams, and invisible or matte finishes are usually more comfortable. Look for descriptions like “dry touch” or “light finish,” but remember that these terms are sensory: a formula might be matte on one person and luminous on another.

If you wear makeup, let the sunscreen settle for a few minutes before the next application. A comfortable texture tends to reduce the urge to apply too little.

Sensitive or reactive skin

The simpler the routine, the easier it will be to understand how your skin reacts to each product. Prefer fragrance-free formulas if you know that fragrance is uncomfortable for you and introduce new products gradually.

“Mineral” does not automatically mean gentler, just as “organic” does not automatically mean less suitable. Tolerance is individual and depends on the complete formula, not just a single UV filter. If you have persistent reactions or specific concerns about your skin, talk to a healthcare professional.

Skin with uneven tone or a tendency for visible marks

Consistent UVA protection is especially relevant when you want to maintain a more uniform tone. A tinted sunscreen can be a practical option, especially if you like to replace foundation with light coverage. In addition to visually evening out the skin, a formula with pigments can help make the routine easier to maintain.

The limitation is simple: the shade needs to match your skin tone. If it doesn't, a non-tinted sunscreen, applied generously, remains an excellent base for your routine.

Mineral and organic filters: what is the difference?

UV filters can be mineral, such as zinc oxide and titanium dioxide, or organic, also known as chemical filters. Both can offer effective protection when present in a well-developed formula and used correctly.

| Type of filter | Potential pros | Aspects to consider |
|---|---|---|
| Mineral | Can leave a more protective feeling and is common in tinted formulas | Can leave a white residue, especially on darker skin tones |
| Organic | Allows for very light, transparent textures that are easy to spread | Some formulas may cause eye discomfort for sensitive individuals |
| Hybrid | Combines different filters to balance protection and sensory feel | The experience always depends on the final formula |

There is no universal answer. If you hate the heavy feeling of some mineral sunscreens, an organic or hybrid formula may encourage daily use. If you prefer a creamier texture or a tinted finish, a mineral formula might make more sense.

It is also worth checking the full label. At Unnamed Cosmetics, the transparency of the INCI list and the explanation of ingredients allow you to better understand the role of each component in the formula, without relying solely on highlighted words on the front of the packaging.

Texture, water resistance, and real-life routine

A morning routine has to fit into real life. If you leave early, work in an office, and spend little time outdoors, you might prefer a light texture that works well under makeup or on its own. If you are going to the beach, exercising, or sweating a lot, look for water resistance and choose a formula that is comfortable to reapply.

Water resistance does not make the product permanent. After swimming, drying your face or body with a towel, or sweating intensely, it is advisable to reapply. It is also useful to reapply during prolonged exposure, even without entering the water.

For the face, think of sunscreen as the final step of your morning routine: cleanse, apply the care you need, moisturize if it makes sense, and protect. At night, there is no need to use sunscreen.

How to apply sunscreen correctly

Effectiveness depends as much on application as it does on the formula. For the face and neck, use a generous and even amount. The two-finger rule—two lines of product along the index and middle fingers—is a popular reference for the face and neck, although the size of the face and the texture of the product may vary.

Don't forget the ears, hairline, neck, décolletage, and the back of your hands when exposed. For the body, apply before going out and spread without rushing to ensure no areas are left uncovered.

If the idea of reapplying over makeup seems impractical, simplify: opt for light makeup on days with higher exposure, take the sunscreen with you, and find a format you can tolerate throughout the day. The best technique is the one you can repeat.

Common mistakes that make choosing harder

Choosing solely by SPF is a frequent mistake. A high SPF without UVA indication does not meet the need for broad-spectrum protection. Another mistake is buying an uncomfortable texture thinking it is “stronger” and then ending up not using it.

It is also common to use sunscreen only in the summer. Daily exposure does not disappear because the sky is cloudy, and a consistent routine is simpler than deciding every day if it is worth applying.

Finally, do not rely solely on the sunscreen in your makeup or a moisturizer with SPF, unless you can apply the necessary amount without compromising the finish. Often, a dedicated sunscreen makes this step clearer and easier to adjust to your level of exposure.

Choosing well means finding a sunscreen with UVA and UVB protection, an appropriate SPF, and a texture you actually enjoy using. When protection fits naturally into your morning, it ceases to be just another complicated step and becomes a simple daily care gesture.
