When To Use & Apply Salicylic Acid Serum In Your Skincare Routine?

In the world of skincare, salicylic acid is a star ingredient renowned for its exceptional ability to combat acne, control sebum production, and unclog pores. But to get the most out of your salicylic acid serum, it’s important to know when to use a salicylic acid serum in your routine. Applying it at the right time of day, morning or night, can enhance its benefits while ensuring your skin remains healthy and protected. Here’s a detailed guide to help you understand when to apply salicylic acid serum and how to incorporate it effectively.

AM Application Of Salicylic Acid Serums

Using salicylic acid in the morning can help start your day with clear, fresh skin. When applied correctly, it works throughout the day to keep pores clean, reduce breakouts, and control oil production. Benefits of morning use include:

• Preventing oil build-up during the day
• Minimising breakouts caused by environmental stressors
• Smoothing skin texture before makeup application

How To Apply Salicylic Acid Serum In The Morning?

• Step 1: Begin with a hydrating, gentle face wash to gently remove excess oil and impurities from the previous night.
• Step 2: If you use a toner, ensure it’s alcohol-free and non-drying.
• Step 3: Apply a few drops of the salicylic acid face serum on clean, dry skin. Focus on oily areas or blemish-prone zones such as the T-zone.
• Step 4: Follow with a lightweight, non-comedogenic day cream to keep skin hydrated and balanced.
• Step 5: This is the most important step. Salicylic acid can make your skin more sensitive to the sun, so finish with a broad-spectrum sunscreen (SPF 30 or higher) to protect your skin from UV damage.

• If your skin is dry or sensitive, you might want to apply salicylic acid only a few times a week in the morning.
• Avoid layering it with other strong actives like retinol or AHAs in the same routine.

PM Application Of Salicylic Acid Serums

Night-time is when your skin repairs and regenerates, making it an ideal window for active ingredients like salicylic acid to work more deeply. Using the serum at night can help remove the day’s buildup of oil, dead skin, and pollutants. Benefits of night use include:

• Encouraging skin renewal while you sleep
• Preventing clogged pores from accumulating overnight
• Enhancing exfoliation without exposure to sun or pollutants

How To Apply Salicylic Acid Serum In The Evening?

• Step 1: Use a makeup remover or cleansing oil followed by a gentle cleanser to thoroughly clean your skin.
• Step 2: Apply a calming or hydrating toner to soothe the skin.
• Step 3: Gently apply the salicylic acid serum on targeted areas or across the entire face, avoiding the eye area.
• Step 4: Apply a nourishing night cream or moisturiser to help restore hydration and support the skin barrier.

• Avoid combining salicylic acid with retinol in the same night routine unless recommended by a dermatologist, as it may increase irritation.
• If using other exfoliants like glycolic acid or lactic acid, alternate them with salicylic acid on different nights.

Frequency Of Use

Whether used in the morning or evening, begin with two to three applications per week. Gradually increase the frequency based on how your skin responds. If dryness, peeling, or redness occurs, reduce usage and apply a rich moisturiser to soothe the skin.


So, when to use salicylic acid serum - AM or PM? The answer depends on your skin type, lifestyle, and overall skincare goals. Morning use can help prevent breakouts during the day and prep your skin for makeup, while night-time application allows the serum to deeply cleanse and support overnight renewal. Whether you include it in your morning or evening routine or alternate between both, consistency is key to seeing results. With the right timing and technique, salicylic acid can become a powerful ally in your journey to clearer, smoother, and healthier-looking skin.
