In this article, we will discuss why sunscreen is necessary for oily skin, how to choose and use it correctly.
Why sunscreen is important for oily skin
1. UV radiation and sebum hyperproduction.
Ultraviolet rays (UVA and UVB) damage the skin by breaking down collagen and elastin, leading to premature wrinkles and loss of elasticity. Oily skin, despite increased sebum production, is not protected from these processes.
Furthermore, studies show that UV radiation stimulates the sebaceous glands to increased activity. In 2013, the Journal of Investigative Dermatology published data demonstrating that UVB rays increase sebum synthesis by 20-30%.
2. Photoaging: An Invisible Process.
It is generally accepted that oily skin ages more slowly (according to the source: Zouboulis et al., 2008). This is partly true – increased sebum secretion does create a natural lipid barrier. However, UVA rays penetrate deep into the dermis, destroying collagen and elastin fibers. Clinical studies confirm that people with oily skin after 30 often develop deep wrinkles in the T-zone - exactly where the sebaceous glands are most numerous.

3. Post-acne and hyperpigmentation.
Solar radiation aggravates inflammatory processes by activating pro-inflammatory cytokines. UVA rays contribute to the darkening of post-inflammatory spots, and UVB rays provoke an inflammatory cascade, aggravating acne.
Dermatologists unanimously agree: abandoning SPF on oily skin is the main reason for the long-term persistence of post-acne.
4. Risk of actinic keratosis.
People with oily skin who neglect sunscreen are 1.5 times more likely to develop actinic keratosis, a precancerous skin condition (data from the American Academy of Dermatology, 2020).
How to choose a sunscreen
When choosing a sunscreen for oily skin, it is important to follow several rules so that the product is not only effective, but also as comfortable as possible.
1. Texture.
Products with oily formulas, creams containing petroleum jelly and lanolin, as well as thick SPF balms are not recommended for oily skin. Products containing petroleum jelly and lanolin can clog pores in acne-prone skin.
Ideal texture:
- Fluids (water-gel base);
- Emulsions with dimethicone (provides a mattifying effect);
- Dry touch formulas (absorb excess sebum).

2. SPF and protection spectrum.
| Index | Recommendation for oily skin |
|---|---|
| SPF | 30-50 (according to the European Association of Dermatologists, an SPF of at least 30 is recommended for everyday use) |
| UVA protection | PA++++ ≈ PPD ≥16 * |
| Filter stability | Tinosorb S, Mexoryl XL (non-degradable in the sun) |
3. Key ingredients.
Essential components that should be included in an SPF for oily skin:
- Niacinamide (4-5%) – reduces sebum secretion, reduces the visibility of pores;
- Zinc oxide (ZnO) – mattifies and has an anti-inflammatory effect;
- Hyaluronic acid – normalizes the skin’s moisture balance without increasing the activity of the sebaceous glands.
The following may also be included in the composition of the products:
- Perlite – absorbs sebum;
- Salicylic acid (0.5%) – prevention of comedones.

4. Filters: chemical or physical
Physical filters, also known as mineral filters, are suitable for sensitive skin, but can clog pores due to titanium dioxide nanoparticles and leave a whitish tint.
Chemical filters (octinoxate, oxybenzone) are more easily and quickly absorbed, but can sometimes cause irritation.
The optimal choice for oily skin are hybrid formulas with zinc and modern photostable filters (Tinosorb M).
How to use sunscreen for oily skin
1. Correct application
- Apply SPF cream 15-20 minutes before sun exposure to allow it to be absorbed and begin to work;
- Use 2 mg of product per 1 cm² of skin (for the face - about 1/4 teaspoon).
- Don't forget to apply SPF to the neck, décolleté and ears.
2. Renewing protection
- Renew SPF every 2 hours in active sun;
- If the skin is oily, use matting wipes before reapplying.
3. Combining with care and makeup
- Cleansing - before applying SPF, use a delicate gel or foam;
- Moisturizing - apply creams with a non-greasy texture or serum;
- Makeup - after applying SPF and before using cosmetics, wait 10 minutes. Foundation can be applied over sunscreen, but it is better to choose products with a mattifying effect.
4. What to do if SPF cream "rolls"?
- Use a primer before applying SPF;
- Choose quickly absorbed textures;
- Avoid silicone bases if they do not suit your skin.
For oily skin, sunscreen is not just cosmetics, but a therapeutic and prophylactic agent. Modern formulas with sebum-regulating ingredients not only protect against UV rays but also normalize sebaceous gland function, prevent post-acne, and slow down photoaging. For those with oily skin, we recommend our mattifying sunscreen SPF 50. It has a mattifying effect and can be used as a makeup base.
