How to Use Lactic Acid for Skin? A Beginner’s Guide


Beautiful and radiant skin is something we all desire and there are countless skincare products and treatments available to help us achieve that goal. One such skincare ingredient that has gained popularity in recent years is lactic acid.

If you’re new to the world of skincare and wondering how to use lactic acid for your skin, you’re in the right place. In this beginner’s guide, we’ll explore the benefits of lactic acid for skin, its various uses, and how to incorporate it into your skincare routine.

What is Lactic Acid?

Lactic acid is a type of alpha hydroxy acid (AHA) derived from fermented milk and other sources. It falls into the category of chemical exfoliants, which are known for their ability to remove dead skin cells, unclog pores, and promote a smoother and more youthful skin. Lactic acid is milder than some other AHAs like glycolic acid, making it an excellent choice for individuals with sensitive/dry skin or those new to chemical exfoliants.

Lactic Acid Skin Benefits

Here are the ways in which lactic acid benefits your skin:

1. Exfoliation: Gently exfoliates the skin’s surface, helping remove dead skin cells and promote cell turnover. This process can lead to a brighter and more even-toned complexion.

2. Hydration: Unlike some other exfoliants that can be drying, lactic acid has the added benefit of moisturizing the skin. It helps improve the skin’s natural moisture barrier, making it suitable for those with dry or dehydrated skin.

3. Improved Texture: Regular use of lactic acid can help reduce the appearance of fine lines, wrinkles, and rough skin texture, leaving your skin looking smoother and more youthful.

4. Skin Brightening: Lactic acid can also help fade dark spots, hyperpigmentation, and acne scars, resulting in a more even and radiant complexion.

5. Acne Management: Lactic acid has antibacterial properties that can be beneficial for individuals with acne-prone skin. It can help unclog pores and reduce the formation of acne lesions.

Lactic Acid Uses for Skin

Here are the ways in which you can incorporate lactic acid in your skincare routine:

1. Peels: Lactic acid peels, which are typically administered by dermatologists or skincare professionals, involve applying a higher concentration of lactic acid for skin to address specific skin concerns. These peels can provide more dramatic results but should be done under professional supervision.

2. Serums: Lactic acid serums are popular for at-home use. They contain a lower concentration of lactic acid and can be applied daily or as directed. These serums are suitable for beginners looking to introduce lactic acid into their skincare routine gradually.

3. Moisturizers and Creams: Some moisturizers and creams are formulated with lactic acid, making it easy to incorporate into your daily skincare routine. These products provide both exfoliation and hydration.

4. Cleansers: Lactic acid cleansers are another option for gentle exfoliation during your daily cleansing routine. They are a good choice for those with sensitive skin.

Tips to Use Lactic Acid for Your Skin

Follow these tips for best results:

1. Patch Test: Before using lactic acid for face, perform a patch test on a small, inconspicuous area of skin to ensure you don’t experience any adverse reactions.

2. Start Slowly: If you’re new to lactic acid, begin with a product that has a lower concentration (around 5-10%) to avoid over exfoliation. Gradually, increase the frequency and concentration as your skin becomes accustomed to it.

3. Follow Instructions: Always follow the instructions provided with your lactic acid product. Some products are meant to be applied at night and it’s crucial to wear sunscreen during the day as lactic acid can increase your skin’s sensitivity to the sun.

4. Be Patient: It may take a few weeks to see noticeable results, so be patient and consistent with your skincare routine.


Lactic acid is indeed a valuable addition to your skincare routine, offering a range of benefits for your skin. Whether you’re looking to achieve smoother, brighter, or more hydrated skin, lactic acid can help you achieve your skincare goals. 
Just remember to start slowly, follow the instructions, and be patient in order to enjoy the lactic acid skin benefits. With the right approach, you’ll be on your way to healthier, more radiant skin in no time.
