What is the optimal amount of facial cleansing?

How Often Should You Cleanse Your Face?

The frequency of facial cleansing treatments depends on your skin type, its needs, and the cleansing method used. Regular skin cleansing helps maintain a healthy appearance, prevents imperfections, blackheads, and excess sebum. In most cases, it is recommended to perform manual facial cleansing every four weeks, as this is linked to the skin’s natural renewal process, known as keratinization.

What is Keratinization and Why Is It Important?

Keratinization is the process in which skin cells gradually move from the deeper layers of the epidermis to the surface, where they eventually shed. A full skin renewal cycle takes approximately 28 days, though it may take longer for older or very dry skin. Performing a cleansing treatment at regular intervals helps remove accumulated dead skin cells and prevent clogged pores, improving overall skin condition.

Cleansing Frequency Based on Skin Type

Oily and Combination Skin
People with oily or combination skin often experience excess sebum production, clogged pores, and breakouts. In this case, facial cleansing can be done every 3-4 weeks to prevent skin problems and control oil production.
Dry and Sensitive Skin
Dry skin is more delicate and prone to irritation. Excessive cleansing could lead to further dryness and damage to the skin’s protective barrier. It is recommended to cleanse less frequently, approximately every 6-8 weeks, using gentle methods like enzymatic or ultrasonic cleansing.
Normal Skin
Normal skin that does not have major issues with imperfections can be cleansed every 4-6 weeks, depending on individual needs and home care. Regular cleansing helps maintain skin balance and prevent blackheads from forming.
Acne-Prone Skin
Acne-prone skin requires a more individualized approach. Cleansing treatments should be performed carefully, ideally in consultation with a dermatologist or cosmetologist. Over-cleansing can worsen inflammation, so it is essential to determine the appropriate frequency with a professional.

Types of Skin Cleansing and Their Impact on Frequency

Manual Cleansing – This traditional method removes blackheads and impurities. Due to its intensity, it is recommended to perform manual cleansing every 4-6 weeks to allow the skin time to recover.
Ultrasonic (Cavitation) Cleansing – A gentler method using ultrasound waves. It can be performed more frequently, even every 2-4 weeks, especially for sensitive or dry skin.
Chemical Cleansing (e.g., Acids) – Cleansing with AHA, BHA, or PHA acids supports exfoliation. The frequency depends on the type of acid used and the skin’s tolerance, usually every 4-6 weeks.

Benefits of Regular Facial Cleansing

Improved Absorption of Active Ingredients – Cleansed skin free of dead cells and impurities better absorbs skincare products.
Reduced Blackheads and Imperfections – Regular removal of excess sebum and dead cells helps keep pores clean and reduces the appearance of imperfections.
Enhanced Skin Texture and Tone – Cleansing helps smooth the skin and even out its tone.

In my opinion

The optimal frequency of facial cleansing depends on your skin type and the cleansing method used. For manual cleansing, it is recommended to perform the procedure every four weeks, in line with the skin’s natural renewal cycle. Oily skin may require more frequent treatments, while dry and sensitive skin may need them less often. Regular cleansing helps maintain healthy skin, improving texture, tone, and the skin’s ability to regenerate.
