Do you apply sunscreen every morning—or are you one of those people who skip this step because it feels sticky, leaves a white cast, or ruins your foundation? You're not alone. Facial sunscreen is the most neglected step in a routine, even though it's probably the most important.
Good news: in 2025, you no longer have to choose between protection and makeup. Here's everything you need to know to find a facial sunscreen that suits your skin—and your routine.
Why apply facial sunscreen even in winter?
This is the question we hear most often. And the answer is simple: UVA rays are present year-round, in all weather, even behind glass. They are the main culprits behind premature skin aging—wrinkles, dark spots, and loss of firmness.
UVB rays, on the other hand, are more intense in summer and cause sunburn. But both types of rays damage the skin deep down, invisibly and cumulatively.
Applying SPF 50 facial sunscreen every morning is the most effective anti-aging step there is. Before serum, before moisturizer, before anything else.
Sunscreen under makeup: what makes all the difference
For a long time, sunscreen had a terrible reputation in the makeup world: greasy texture, shiny finish, foundation that slides, and a mask-like effect on the skin. All of that is true of beach sunscreens—formulated to withstand water and sand, not for everyday use at the office.
A facial sunscreen designed to be worn under makeup belongs to a different category. It absolutely needs to have:
- A dry, matte finish A good facial sunscreen doesn't leave a greasy film on the surface. It absorbs quickly and leaves a natural finish—neither shiny nor powdery. This makes it possible to apply foundation, BB cream, or powder on top without it sliding or pilling.
- A lightweight, non-sticky texture The texture should be fluid, almost serum-like. If you have to forcefully spread it, the formula isn't suitable for the face.
- No white cast A white cast is the hallmark of poorly formulated mineral filters (zinc oxide, titanium dioxide). Modern chemical filters, such as Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, used in Sun-ell, are invisible on all skin tones.
-
A formula without controversial ingredients Some sunscreens contain controversial ingredients such as oxybenzone, parabens, or PEGs. Always check the INCI list before buying.
Can you use facial sunscreen as a primer?
Yes, as long as you choose the right formula!
A primer has two functions: smoothing the skin’s texture and helping makeup last. A facial sunscreen with a dry finish can do both if it:
- Absorbs in less than 60 seconds
- Leaves an even finish (neither too matte nor too dewy)
- Does not contain heavy silicones that create a barrier between makeup layers
Sun-ell was designed with exactly this in mind. Its lightweight texture absorbs quickly, leaves a natural, non-greasy finish, and works as a makeup base without the need for an additional primer. One less product in your routine, and more sun protection.
Which facial sunscreen should you choose for your skin type?
Normal to dry skin
Look for a formula with hydrating ingredients such as hyaluronic acid, avocado extract, and glycerin. A slightly pearlescent finish (not greasy) may work well. Avoid formulas with denatured alcohol listed first in the INCI list.
Combination to oily skin
Prioritize a matte finish and a non-comedogenic texture. Chemical filters are generally better tolerated than mineral filters for this skin type. Make sure the formula does not contain heavy, occlusive oils.
Sensitive or reactive skin
Choose mineral filters (zinc oxide) or hybrid formulas. Avoid synthetic fragrances and potentially irritating ingredients. Always test on a small area before daily use.
Acne-prone skin
Must be non-comedogenic. Lightweight, water-based formulas are the best allies. Salicylic acid in your routine (such as Pure-lyn), combined with a suitable sunscreen, can even improve your skin’s condition over the long term.
How often should you reapply facial sunscreen?
For daily use in the city, one application in the morning is enough. If you spend time outdoors, reapply every 2 hours. On the face with makeup, use a sunscreen spray or SPF powder to reapply without ruining your foundation.
The recommended amount for the face: 2 fingers (index and middle fingers). This is the amount used in clinical studies. Less than this, and the actual SPF is lower than the level shown on the packaging.
What we put in Sun-ell, and what we leave out
Sun-ell SPF 50 is formulated for daily use on the face, under makeup. Here's why it works:
What it contains:
- Broad-spectrum UVA/UVB filters: optimal protection without a white cast
- Vita Avocare avocado extract: an upcycled moisturizing active ingredient, +250% hydration in 14 days
- Sunflower oil: nourishing without an occlusive effect
Free from controversial ingredients:
- Free from oxybenzone and octinoxate — two controversial filters banned in Hawaii because of their impact on marine ecosystems
- Free from sulfates, parabens, PEGs, phthalates, and formaldehyde
The result: a texture that absorbs in 30 seconds, a natural non-greasy finish, and compatibility tested with makeup.
In summary: how do you choose a facial sunscreen?
- SPF 50 minimum for daily use
- Dry or natural finish if you apply makeup on top
- Non-comedogenic if your skin is combination to oily
- No white cast for all skin tones
- Moisturizing ingredients to prevent long-term skin dryness
- Free from controversial ingredients — always check the INCI list
Sunscreen is the only skincare product whose benefits for skin aging have been scientifically proven. It deserves a permanent place in your routine—not just in summer.
