Index

Shiny skin a few hours after washing your face is a common problem. Sometimes blackheads, visible pores, and pimples also appear.

The temptation is to wash more often or use highly degreasing products. But this isn't always the right choice.

Oily skin needs simple, regular care, not aggressive treatments.

Why skin becomes oily: the most common causes

Sebum is a natural substance that helps protect the skin. When the sebaceous glands produce too much of it, the face can appear shiny, especially on the forehead, nose, and chin.

The most common causes are:

  • Genetics: Some people naturally have increased sebum production.

  • Hormones: especially during puberty, but also at other stages of life.

  • Cosmetic products: Some formulations may be too heavy or cause clogged pores.

  • Stress: may contribute to worsening blemishes in some people.

  • Environmental factors: Heat and humidity can make the shine more noticeable.

Oily skin isn't necessarily a result of poor hygiene. Constantly washing your face doesn't address the underlying cause of sebum production and can irritate the skin barrier.

The role of hormones

Androgens affect the activity of the sebaceous glands. This is one of the reasons why oily skin is common during adolescence.

Even in adulthood, skin changes related to hormonal changes can occur.

If the appearance of acne is sudden, severe, or associated with other symptoms, it is helpful to talk to a doctor.

Impure skin: meaning and differences from oily skin

La oily skin It is recognized above all by the abundant production of sebum and by its shine.

The expression unclean skin, instead, is commonly used to describe skin with blackheads, clogged pores and other imperfections.

They're not exactly the same thing.

A person can have oily skin without developing acne. Likewise, acne can appear even on skin that doesn't appear particularly shiny.

Frequent lucidityComedones and inflammatory lesions
High sebum productionPimples, papules or pustules
Pores that may appear noticeableIn the most serious cases, nodules and risk of scarring

If you mostly have shine and a few blackheads, a proper skincare routine may be enough.

If deep, painful, or persistent lesions appear, don't rely solely on cosmetics.

Skincare for oily skin: what to use morning and night

A good one skincare for oily skin It doesn't necessarily have to include many products.

To get started, focus on three essential steps: cleanse, moisturize, and protect from the sun.

1. Gentle cleanser

Wash your face with a cleanser suitable for oily skin, usually in the morning and evening.

Choose formulas that cleanse without leaving your skin feeling tight.

There's no need to look for very aggressive products: excessive cleansing can cause irritation and dryness.

2. Toner: is it really necessary?

Tonic is optional.

It may be pleasant to use, but it is not essential to properly cleanse your skin and does not permanently tighten pores.

If you want to include it in your skincare routine, choose a well-tolerated formula, avoiding ingredients that cause burning or irritation.

3. Light moisturizer

Even oily skin needs hydration.

A light cream, preferably non-comedogenic, can help keep the skin barrier in good condition without weighing down the face.

Gel or fluid formulations may be more comfortable for those who don't like rich creams.

4. Salicylic acid for blackheads and clogged pores

Salicylic acid, also known as BHA, is an ingredient used in skin products for blackheads and blemishes.

It can help reduce the buildup of dead skin cells in pores.

If you've never used it before, start with moderate frequency, following the product directions and observing how your skin reacts.

Don't combine it immediately with several other exfoliants: you may increase the risk of irritation.

A serum with salicylic acid can be helpful when blackheads are the main problem.

5. Clay mask: an optional help

A clay mask can temporarily absorb some of the surface sebum and make the skin less shiny.

However, it is not a necessary treatment and does not replace essential products.

If you use it, follow the times indicated on the package and stop applying it if you experience irritation.

Sun protection is also important for those with oily skin.

Choose a broad spectrum product with SPF 30 or higher, suitable for the face and comfortable to wear.

If you have blemishes, you can look for lightweight, non-comedogenic formulas. Sunscreen also helps limit the darkening of pimple marks.

A light SPF 50 face sunscreen can be particularly practical for everyday use.

What to do immediately if your skin is very shiny

If your face already appears greasy after a few hours, don't automatically increase the number of washes.

Try this organization instead:

In the morning: gentle cleanser, light cream if needed, and sunscreen.

During the day: Avoid rubbing your face constantly. If necessary, use a face wipe without rubbing.

In the evening: Remove makeup, sunscreen, and impurities with a proper cleanser, then apply a moisturizer.

If your skin becomes red, burning, or peeling, reduce potentially irritating products and seek professional advice.

Impure skin: useful natural remedies and precautions

Aloe vera, green tea, and tea tree oil are often recommended for blemishes.

However, evidence regarding their effectiveness is limited or variable, and not all natural remedies are suitable for all skin types.

In particular:

  • Aloe vera: Some formulations may have a soothing effect, but can still cause reactions.

  • Green tea: Some ingredients derived from green tea are studied in cosmetics, but home compresses do not have guaranteed results.

  • Tea tree: Essential oil may irritate or sensitize the skin, especially when used neat.

Avoid applying lemon, baking soda, or harsh DIY mixtures to your face.

If you have persistent acne, natural remedies should not replace appropriate treatments.

Diet and oily skin: how important is it?

Diet isn't the only cause of oily skin.

Some studies suggest an association between high-glycemic foods and worsening acne in certain people. However, the evidence doesn't suggest that eliminating a single food automatically solves the problem.

For general well-being, it is helpful to maintain a balanced diet, with vegetables, fruit, whole grains and adequate protein sources.

You don't need drastic diets to manage facial shine.

Even one healthy lifestyle can contribute to the overall well-being of the skin.

Mistakes that can make oily skin worse

Some habits can irritate the skin or promote the appearance of blemishes.

Above all, avoid:

  • Too frequent washing and aggressive detergents.

  • Strong scrubs for inflamed pimples.

  • Continuously squeeze blackheads and pimples.

  • Changing many products at the same time.

  • Skip removing makeup before bed.

  • Using cosmetics that cause irritation or clogging of pores.

  • Exposing yourself to the sun without adequate protection.

The solution is not to completely eliminate sebum, but to manage the skin without damaging its protective barrier.

How long does it take to see improvements?

It depends on the problem and the products used.

The feeling of clarity can also change rapidly with a suitable cosmetic formulation.

Blackheads and pimples, on the other hand, may require several weeks of consistent treatment.

If you use an active product, follow the directions and don't increase the number of applications just because you don't see immediate results.

How to understand if the products work

Observe over time:

  • the frequency of new pimples;

  • the presence of blackheads;

  • the tolerability of the products;

  • the appearance of redness, burning or dryness;

  • clarity throughout the day.

Don't evaluate a skincare product solely based on its immediate mattifying effect.

When to see a dermatologist

Oily skin, by itself, is not necessarily a medical condition that needs to be treated.

However, it is advisable to consult a dermatologist when:

  • deep or painful pimples appear;

  • scars begin to form;

  • imperfections persist or worsen;

  • the products used cause significant irritation;

  • acne causes emotional distress;

  • you suspect that the skin changes are associated with a hormonal problem.

A dermatologist can distinguish simple blemishes from acne that requires specific treatment.

In summary

To manage the oily and impure skin you don't necessarily need many products.

The foundation is gentle cleansing, combined with hydration and sunscreen. Salicylic acid can be helpful for blackheads, while toners and masks are optional.

Avoid harsh products and give your skin time to respond to treatments.
