When it comes to skincare, lactic acid is a well-known name among beauty enthusiasts. This ingredient can make skin soft, radiant, and improve its texture effectively. However, not everyone fully understands lactic acid and how to use it safely and optimally. Today, Goldskin will explore the benefits, uses, and ways to effectively incorporate lactic acid into your skincare routine in a detailed and easy-to-understand manner.

What Is Lactic Acid? And the Chemical Structure of Lactic Acid

Lactic acid is a type of alpha-hydroxy acid (AHA) known for its ability to exfoliate and improve skin hydration. Its molecular formula is C3H6O3, with a hydroxyl group (OH) and a carboxyl group (COOH) in its chemical structure. This structure enables lactic acid to dissolve in water and penetrate the skin, helping to remove dead cells and promote skin renewal.

Lactic acid is considered a gentler option compared to other AHAs, such as glycolic acid, making it suitable for those with sensitive or easily irritated skin.

How Lactic Acid Works on the Skin

Effects On The Stratum Corneum

Lactic acid works directly on the stratum corneum, loosening the bonds between dead skin cells, thus removing them gently. This helps the skin become smooth and reduces the risk of clogged pores, which can lead to blackheads and hidden acne.

Stimulates New Cell Production

In addition to exfoliating, lactic acid stimulates new skin cell production, helping to reduce wrinkles and improve skin texture. According to research from the Journal of Dermatological Science, regular use of lactic acid can increase skin cell turnover by up to 25%, allowing the skin to recover faster and stay healthier.

Benefits of Lactic Acid for the Skin

Lactic Acid And Its Exfoliating Power

Lactic acid is known for its gentle exfoliating ability without causing strong irritation, removing dead cells and accumulated dirt on the skin’s surface. This not only brightens the skin but also allows other skincare products to absorb more effectively.

Analysis Of How Lactic Acid Removes Dead Cells And Improves Skin Texture

When applied to the skin, lactic acid softens the stratum corneum and breaks the bonds between dead cells. A 2020 clinical study showed that after using lactic acid for eight weeks, skin softness increased by up to 40%, helping the skin become smoother.

Enhances Hydration And Softens Skin

One of lactic acid’s unique features is its ability to retain moisture in the skin. Unlike glycolic acid, lactic acid not only exfoliates but also attracts and retains moisture, making the skin soft and smooth. According to research from the American Academy of Dermatology, skin treated with lactic acid increased moisture levels by up to 30% after four weeks of continuous use.

The Role Of Lactic Acid In Maintaining Moisture And Improving Skin Elasticity

Lactic acid not only softens the skin but also improves elasticity by stimulating collagen production. Regular use of lactic acid products can help reduce wrinkles and increase skin firmness.

Brightens And Evens Skin Tone

Lactic acid can reduce pigmentation and improve uneven skin tone. This process occurs as lactic acid removes dead cells containing excess melanin and promotes new skin cell renewal. According to a clinical study, using lactic acid at a 10% concentration for six weeks helped fade dark spots and brighten the skin by up to 20%.

Strengthens The Skin Barrier

Research from the Journal of Dermatological Science shows that lactic acid also helps strengthen the skin barrier, enabling it to resist harmful environmental factors and prevent water loss through the skin. Lactic acid helps retain essential lipids in the skin, enhancing overall skin health.

How to Use Lactic Acid Safely and Effectively

Choosing The Right Concentration For Each Skin Type

• Sensitive skin: Start with a concentration of 3-5% to avoid irritation.
• Normal and combination skin: A concentration of 5-10% can yield noticeable results.
• Thick and oily skin: Higher concentrations, between 10-12%, can be used, but watch the skin’s reaction closely.

Skincare Routine And Steps For Using Lactic Acid

1. Cleansing: Use a gentle cleanser to remove dirt.
2. Toner: Balance the skin with an alcohol-free toner.
3. Apply lactic acid: Apply a moderate amount to dry skin and wait 5-10 minutes for absorption.
4. Moisturizing: Use a moisturizer to lock in moisture and protect the skin.

Combining With Other Products Like Vitamin C, Niacinamide

Lactic acid can be combined with niacinamide to soothe and nourish the skin. However, be cautious when using it with vitamin C due to differences in pH levels. The best practice is to use lactic acid in the evening and vitamin C in the morning for optimal effectiveness.

Frequency And Timing Of Lactic Acid Use

Lactic acid should be used in the evening to allow the skin time to recover and avoid sun exposure. Start with 2-3 times per week and gradually increase frequency as the skin adapts to the product.

Recommendations From Dermatologists

According to dermatologist Nguyen Thuy An, “Lactic acid is an excellent choice for those looking to improve skin texture and moisture. However, be sure to use it in the correct dosage and always pair it with sunscreen during the day.”

Important Tips When Using Lactic Acid

Protect Skin From Sun Exposure, Combine With Moisturizing

• Sunscreen: Always apply sunscreen with SPF 30 or higher when using lactic acid to protect the skin from UV damage.
• Moisturize: Use products containing hyaluronic acid or ceramides to restore the skin barrier and retain moisture.

Using lactic acid correctly offers significant benefits for the skin. However, always listen to your skin’s needs and adjust usage frequency to achieve the best results. If you have any questions, leave a comment so Goldskin can help you find the most accurate answer.
