Lactic Acid

Lactic acid is a gentle alpha hydroxy acid (AHA) commonly used in skincare to exfoliate the skin while helping maintain hydration. It works by loosening the bonds between dead skin cells, allowing them to shed more evenly and reveal smoother, brighter-looking skin underneath.

Unlike stronger exfoliating acids, lactic acid is known for its balance between effectiveness and comfort. This makes it a popular choice for people who want visible skin refinement without excessive dryness or irritation.

Shop lactic acid skincare online to support smoother texture, improved radiance, and a more even-looking complexion—especially if your skin feels dull, rough, or congested.

What is Lactic Acid?

Lactic acid is an AHA derived from fermented sugars. In skincare, it is used primarily as a chemical exfoliant, meaning it removes dead skin cells without physical scrubbing. Its larger molecular size compared to some other acids allows it to work closer to the skin’s surface, making it generally milder and more suitable for regular use.

Many formulations combine lactic acid with hydrating and barrier-supportive ingredients to help maintain comfort while improving skin clarity.

Benefits and Features of the Welzo Lactic Acid Collection

Lactic acid products are designed to improve skin texture while supporting hydration. They are often chosen by those who want exfoliation without the harshness associated with stronger acids.

• Smoother skin texture: Helps reduce roughness and uneven surface buildup.
• Improved radiance: Encourages fresher-looking skin by removing dulling dead cells.
• Supports hydration: Lactic acid can help attract moisture, unlike more drying exfoliants.
• Gentler exfoliation option: Suitable for those new to chemical exfoliation.

If your routine focuses on maintaining a balanced complexion, you may also explore products within the complexion category to complement exfoliation with tone-evening coverage and finish.

Why is Lactic Acid Important?

As skin naturally renews itself, dead skin cells can accumulate on the surface, leading to dullness, uneven texture, and clogged pores. Lactic acid helps support the natural exfoliation process, allowing skincare products to absorb more effectively.

This is particularly helpful for those dealing with dryness or flakiness. If dehydration is a concern, pairing exfoliation with routines designed for dry skin skincare can help maintain comfort while improving smoothness.

Best Products in Lactic Acid

Lactic acid is available in a variety of formats, making it easy to tailor exfoliation to your skin type and routine preferences.

• Lactic acid toners: Ideal for light, regular exfoliation.
• Lactic acid serums: Offer more targeted resurfacing benefits.
• Lactic acid cleansers: Provide mild exfoliation during cleansing.

For gentle cleansing before exfoliation, products such as micellar water skincare can help remove makeup and impurities without disrupting the skin barrier.

How to Use Lactic Acid?

Lactic acid is typically used in the evening, as exfoliation can increase skin sensitivity to sunlight. Start slowly, especially if you are new to chemical exfoliants.

• Cleanse: Begin with a gentle cleanser to remove surface impurities.
• Apply lactic acid: Use according to product instructions, avoiding overuse.
• Moisturise: Follow with a hydrating cream to support the skin barrier.

During daytime routines, protecting freshly exfoliated skin is essential. Using a daily product from the sunscreen skincare range can help reduce the risk of UV-related sensitivity.

Side Effects or Interactions of Lactic Acid

Lactic acid is generally well-tolerated, but mild tingling or temporary redness can occur, especially when first introduced.

• Sensitivity: Patch test before full use, particularly on reactive skin.
• Over-exfoliation: Avoid combining with multiple exfoliating products at once.

If your skin is easily irritated, focusing on barrier support with products like ceramides can help maintain balance while exfoliating.

Different Types of Lactic Acid Available

Lactic acid products vary in concentration and formulation. Lower concentrations are typically used for daily or frequent exfoliation, while higher strengths are reserved for weekly treatments.

Some routines alternate lactic acid with other exfoliating ingredients depending on skin needs. For those managing blemishes or congestion, alternating carefully with options such as salicylic acid skincare may be considered, provided the skin tolerates it.
