Lactic Acid for Dry Skin

The Science Behind Lactic Acid's Hydrating Properties

Lactic acid isn't just the culprit for your sore muscles after a hard day at the gym, it's also the savior of dry skin! Let's demystify lactic acid and see how it makes your skin glow.

Lactic acid is an alpha hydroxy acid (AHA) that has a molecular structure that allows it to easily penetrate the surface of the skin and deeply moisturize. Not only does lactic acid remove dead skin cells, it also promotes cell turnover, making your skin look smoother and younger. Even better, lactic acid strengthens the skin barrier function, helping to lock in moisture and prevent water loss.

Imagine your skin is like a dry sponge, and lactic acid is that timely rain, making the sponge soft and elastic again. Scientists have also found that lactic acid can stimulate the production of natural moisturizing factors (NMFs) in the skin, and these small molecules are the key to skin hydration!

How to Incorporate Lactic Acid into Your Skincare Routine

Now that we know the amazing L-lactic acid benefits, the next step is how to incorporate it into your daily skincare routine.

First, don’t rush to put all lactic acid products on your face. Take your time and work your way up. Beginners can start with a low-concentration lactic acid product, such as a toner or serum with 5% lactic acid. Gently pat it onto your face after cleansing at night, then apply moisturizer. Lactic acid is a night owl, and using it during the day may make your skin more sensitive to the sun, so it’s best to use it at night. Next, gradually increase the frequency of use, from twice a week to daily, but always observe your skin’s reaction. If your skin starts to feel red, swollen or stinging, it means you need to slow down and give your skin some time to adapt. Finally, don’t forget to use sunscreen during the day. Although lactic acid can make your skin look brand new, it will also make it more vulnerable to UV damage. In short, lactic acid is like a gentle skincare mentor. As long as you treat it with patience, it will definitely bring you unexpected surprises!

Potential Side Effects and Precautions When Using Lactic Acid

  • Of course, although lactic acid used in cosmetics is good, it is not for everyone to use casually. First of all, lactic acid may cause slight tingling of the skin, especially for those who have never used AHA products. Therefore, it is best to test it behind the ear or on the inside of the wrist when using it for the first time to ensure that there is no allergic reaction before using it on the face.

  • Secondly, lactic acid makes the skin more sensitive to sunlight, so you must use sunscreen during the day. Sunscreen with SPF30 or above is a good choice.

  • Also, although lactic acid can remove dead skin cells, excessive use may cause damage to the skin barrier, redness, swelling, dryness and other problems.

  • Therefore, when using lactic acid products, you must pay attention to the appropriate amount and proceed step by step. For those with particularly sensitive skin or skin diseases, it is best to consult a dermatologist before use to ensure safety.

  • Finally, pregnant and breastfeeding women should also consult a doctor before using lactic acid products to ensure safety for themselves and their babies.

In short, although lactic acid is the "star" in the skin care industry, we also need to treat it with caution to maximize its effectiveness. Remember, skin care is a long-term battle, and patience and carefulness are the key to victory!
