Looking for the difference between physical and chemical sunscreens ? Choosing a sunscreen is no longer a secondary step in your skincare routine; it's essential for protecting your skin from damage, pigmentation, stretch marks, and premature aging. With so many types on the market, this question is important: what's the difference between physical and chemical sunscreens? And which one is truly best for your skin?

In this guide, we explain the real differences between the two types, helping you choose the most suitable one according to your skin type, lifestyle, and the climate in Saudi Arabia, with practical recommendations from Lafeminette.


Why does choosing sunscreen require awareness of the different types?


The role of sunscreen in protecting the skin: Sunscreen not only prevents tanning, but also protects the skin from:

  • deep pigmentation
  • Cell damage caused by ultraviolet radiation
  • Early appearance of fine lines

Regular daily use is the real difference between healthy skin and skin that becomes stressed over time.

The impact of the climate in Saudi Arabia on the need for protection: Strong and continuous exposure to the sun in Saudi Arabia makes choosing a suitable sunscreen essential, especially with the UV index being high most days of the year, even in winter or inside a car.


What is physical sunscreen?

How does physical sunscreen work on the skin's surface?

Physical (mineral) sunscreen acts as a reflective shield, forming a layer on the skin's surface that reflects UVA and UVB rays away from the skin instead of absorbing them.

Features of physical sunscreen

  • Gentle on the skin
  • Suitable for sensitive skin
  • Its effect begins immediately upon application.
  • Less likely to cause an allergic reaction


Disadvantages of physical sunscreen

  • It may leave a slight white residue.
  • Some formulations are thicker
  • It needs to be well distributed on the skin


Physical or chemical sunscreen? | Discover the difference and the best types


What is chemical sunscreen?

How does it absorb ultraviolet rays?

Chemical sunscreen works by absorbing ultraviolet rays and converting them into harmless heat within the layers of the skin, which is then eliminated by the body.


Features of chemical sunscreen

  • Light texture and fast absorption
  • It leaves no white residue
  • Suitable for use under makeup


Disadvantages of chemical sunscreen

  • It may cause an allergic reaction in some skin types.
  • It needs 15–20 minutes before sun exposure.
  • Not always suitable for very sensitive skin


Which is better, physical or chemical sunscreen?

According to skin type

  • For sensitive skin: Physical therapy is often the safest option.
  • Oily skin: Chemical or combination formulations
  • Dry skin: physical or moisturizing formula
  • Combination skin: Depends on texture and comfort after use


According to your daily use

  • For prolonged sun exposure: physical or hybrid
  • For everyday use within the city: Mild chemical
  • Under makeup: chemical or invisible formula


There is no such thing as "absolutely the best"; the best option is the one that suits your skin and does not cause it discomfort.


Best sunscreen for sensitive combination skin

Sensitive combination skin needs a sunscreen that balances light hydration and shine control without causing irritation. The best option is a sunscreen with the following formula:

  • Lightweight and fast absorption
  • Perfume and alcohol free
  • Non-comedogenic

It is preferable to choose a sunscreen with an SPF of 30–50 that has a comfortable texture, does not leave a greasy layer on the T-zone, and does not cause dryness of the cheeks.


Sunscreen for sensitive and dry skin

Dry, sensitive skin needs double protection, from the sun and from moisture loss and the effects of climate. Therefore, sunscreen is recommended:

  • Rich in moisturizing ingredients
  • Supports the skin barrier
  • It relieves the feeling of tightness after sun exposure.

Using a sunscreen specifically formulated for this type helps reduce irritation and keeps skin smooth all day, especially in hot and dry weather.


Best sunscreen for pigmentation

For skin suffering from pigmentation or melasma, sunscreen is not an option but a daily necessity. The best sunscreen for pigmentation is the one that:


  • Provides high protection against UVA and UVB rays
  • It prevents the darkening of existing spots.
  • Suitable for sensitive skin and does not cause irritation

Daily adherence to sunscreen reduces the worsening of pigmentation and enhances the results of any brightening routine.


Best natural sunscreen and whitener

It is important to clarify that sunscreen does not whiten the skin instantly, but it does:

  • Prevents skin darkening
  • Maintains natural skin tone
  • It supports long-term color uniformity

The best “whitening” sunscreen is one that protects against the sun and contains gentle ingredients that support skin radiance, without making unrealistic promises.


Best sunscreen for sensitive and oily skin

This type of skin needs sunscreen:

  • Very light
  • Non-greasy
  • It does not clog pores.

Liquid or gel formulations are often the best option, ensuring that the product is free of irritants that may increase oil secretion or cause redness.


Best sunscreen for dry skin

Dry skin benefits from sunscreen:

  • With a comfortable creamy texture
  • Supports all-day hydration
  • Prevents sun-induced peeling

Using a suitable sunscreen reduces chronic dryness and maintains a healthy and radiant appearance of the skin.


What is the right sunscreen for sensitive skin?

The sunscreen suitable for sensitive skin is the one that:

  • It contains gentle ingredients
  • Perfume and alcohol free
  • Tested on the most sensitive skin possible

The most important thing is how your skin responds to it, so it is always advisable to try a small amount before regular use.


What is the best medical sunscreen for sensitive skin?

Medical sunscreen for sensitive skin usually consists of:

  • With a well-thought-out formula
  • Designed to reduce irritation
  • Suitable for extended daily use

“Medical” does not necessarily mean that it is heavy, but rather that it is designed to protect the skin without affecting its natural balance.


What is the best sunscreen with foundation for sensitive skin?

The best option is sunscreen:

  • light
  • fast absorption
  • It doesn't cake under makeup.

It can be used as a smooth base before foundation, protecting the skin without affecting the makeup's staying power or appearance.

  • Suitable for sensitive skin

The main difference between physical and chemical sunscreens lies in their method of protection. Physical sunscreens reflect ultraviolet rays at the skin's surface, while chemical sunscreens absorb them into the skin. Choosing the most suitable type depends on skin type and sensitivity. Sensitive skin tends to prefer physical sunscreens, while normal or oily skin prefers lighter chemical or combination sunscreens. Trusted products like Laviminate are recommended.


Frequently Asked Questions (FAQ):

Yes, provided it is mild and non-comedogenic, and the skin is thoroughly cleansed at the end of the day.

Yes, some hybrid formulations combine physical and chemical components for a better balance between protection and texture.
