If you’ve dipped your toes into the vast ocean of skincare products, you’ve probably come across two buzzy ingredients: lactic acid and hyaluronic acid. These acids are not just for chemists to geek out about; they can make a significant difference in your skincare routine.
But, which one should you choose? Let’s dive into the world of acids and find out what makes lactic acid and hyaluronic acid unique.

The Basics: Lactic Acid
What is Lactic Acid?
First things first, lactic acid is not the stuff that makes your muscles ache after a strenuous workout – that’s lactic acid too, but we’re talking about skincare here! Lactic acid is an alpha hydroxy acid (AHA) derived from sour milk or fermented fruits and vegetables. Don’t worry; the lactic acid used in skincare products doesn’t smell like spoiled milk!
How Does It Work?
Lactic acid is a gentle exfoliant. It works by dissolving the ‘glue’ that holds dead skin cells together, helping them slough off more easily. This exfoliation process leaves your skin looking brighter, smoother, and more youthful. It’s like a mini spa day for your face!
Skin Benefits of Lactic Acid
- Exfoliation: Lactic acid helps remove dead skin cells, improving skin texture and promoting cell turnover.
- Hydration: Unlike some other exfoliants, lactic acid also has a hydrating effect. It helps your skin retain moisture, making it a great choice for those with dry or sensitive skin.
- Hyperpigmentation: Lactic acid can lighten dark spots and hyperpigmentation over time, leaving your skin looking more even-toned.
- Fine Lines and Wrinkles: It can also help reduce the appearance of fine lines and wrinkles, giving you that youthful glow.
Who Should Use Lactic Acid?
Lactic acid is generally safe for most skin types, including sensitive skin. However, if you have extremely sensitive skin, it’s a good idea to do a patch test first and start with a lower concentration. Always remember to follow up with sunscreen, as exfoliated skin can be more sensitive to the sun.
The Basics: Hyaluronic Acid
What is Hyaluronic Acid?
Hyaluronic acid, often lovingly abbreviated as “HA,” is a naturally occurring substance found in our skin, joints, and eyes. In skincare products, it’s often synthesized in the lab, so don’t worry, no one’s squeezing it out of their joints for your face cream!
How Does It Work?
Hyaluronic acid is a humectant, which means it attracts and retains moisture. It’s like a sponge for your skin, holding up to 1000 times its weight in water. When applied topically, it hydrates the skin by drawing in moisture from the environment and the deeper layers of your skin.
Skin Benefits of Hyaluronic Acid
- Intense Hydration: The most significant benefit of hyaluronic acid is its ability to provide deep hydration, leaving your skin plump and supple.
- Reduces Fine Lines and Wrinkles: By hydrating the skin, it can temporarily reduce the appearance of fine lines and wrinkles.
- Soothes Irritation: HA is gentle and can help soothe irritated or inflamed skin.
- Compatibility: It’s generally suitable for all skin types, from dry to oily.
Who Should Use Hyaluronic Acid?
Hyaluronic acid is a skincare superhero that’s safe for almost everyone. If you have dry or dehydrated skin, it’s a must-have. But even if your skin is on the oily side, don’t dismiss it. Hydration is essential for all skin types, and hyaluronic acid can provide just that without making your skin feel greasy.
Lactic Acid vs. Hyaluronic Acid: The Face-Off
Now that we’ve introduced our contenders, let’s see how lactic acid and hyaluronic acid stack up against each other in the ring of skincare.
- Lactic Acid: Primarily an exfoliant, it focuses on removing dead skin cells and improving skin texture.
- Hyaluronic Acid: A hydration powerhouse, it’s all about locking in moisture and keeping your skin plump and dewy.
2. Skin Type Compatibility
- Lactic Acid: Generally suitable for most skin types, but those with sensitive skin should start with lower concentrations.
- Hyaluronic Acid: Universally compatible and a must for dry or dehydrated skin.
- Lactic Acid: Usually found in serums, toners, and chemical peels. Best used at night due to its exfoliating properties.
- Hyaluronic Acid: A common ingredient in moisturizers, serums, and even sheet masks. Can be used day and night for hydration.
- Lactic Acid: Offers smoother, brighter, and more even-toned skin with consistent use. Ideal for those dealing with acne scars and uneven skin texture.
- Hyaluronic Acid: Instantly plumps and hydrates the skin, reducing the appearance of fine lines and giving a dewy complexion.
5. Sunscreen Alert
- Lactic Acid: Exfoliated skin can be more susceptible to sun damage, so sunscreen is a must when using lactic acid.
- Hyaluronic Acid: No sun sensitivity concerns here, but you should still wear sunscreen daily for overall skin protection.
Can They Coexist in Your Skincare Routine?
Absolutely! Lactic acid and hyaluronic acid can be best buddies in your skincare regimen. Here’s how to incorporate them:
- Morning Routine:
- Cleanse your face.
- Apply a hyaluronic acid serum to hydrate your skin.
- Follow up with sunscreen to protect your skin from UV rays.
- Evening Routine (2-3 times a week):
- Cleanse your face.
- Apply a lactic acid serum or toner to exfoliate.
- Let it sit for a few minutes.
- Apply a hyaluronic acid serum to lock in moisture.
- Finish with a moisturizer.
Remember, it’s crucial to introduce new products gradually to avoid overwhelming your skin. Start with a lower concentration of lactic acid and, if needed, work your way up.
