lactic acid and niacinamide

Can You Mix Niacinamide and Lactic Acid?

Although both lactic acid and niacinamide are beneficial to the skin, can they be used in the same skincare routine? Read on to find out.

It is an alpha hydroxy acid that exfoliates the skin to minimize the signs of aging, such as fine lines and dark spots. Vitamin B3 in the form of niacinamide has been shown to enhance skin look by minimizing fine lines and wrinkles while also reducing redness and hyperpigmentation.

Can you use lactic acid and niacinamide together as part of the same skincare routine? Yes, which is great news. But it’s important to apply them in a way that ensures the highest efficiency of both products. To do this, you must allow at least 30 minutes between putting niacinamide on top of the lactic acid.

Let’s take a look at why you may want to include lactic acid and niacinamide into your skincare regimen.

Lactic Acid

AHA lactic acid, which is one of the less well-known AHAs, is generated from soured milk and sugars from fruits. Because of its bigger molecular size, it is difficult to penetrate too deeply into the skin, causing irritation to the skin. It will act on the skin’s outer surface, clearing it of dead skin cell build-up and pollutants that can clog pores and cause the skin to become congested.

It also has unique humectant properties, which means it can help to increase the skin’s natural moisture factor. Because of this, the skin has the potential to defend itself from environmental aggressors and free racial damages, such as pollution and UV rays.

This multi-talented skin component can seal moisture into the skin’s surface, minimize the appearance of pores, and target any difficulties with dark spots and hyperpigmentation that could be present on the skin. When you maintain the lipid barrier of the skin moisturized, you’ll notice that your skin will stay in the best condition.

Niacinamide has the additional benefit of helping to control sebum production in the skin, which means that people with all skin types will benefit from including this talented humectant in their daily routine.

Benefits of Lactic Acid

Lactic acid is an alpha hydroxy acid (AHA) obtained from milk and vegan sources such as sugarcane. It works by softly exfoliating dead skin cells and boosting cell turnover. The following are just a few of the benefits of lactic acid:

  • Lactic acid exfoliates dead skin cells, which helps to reduce the appearance of dark spots, hyperpigmentation, and uneven skin tone, as well as enhance the overall clarity of the skin.
  • A 12 percent concentration of lactic acid has been demonstrated to boost epidermal and dermal firmness and thickness, which may help reduce the appearance of fine lines and wrinkles.
  • Lactic acid also has the additional advantage of binding water to the skin, which increases hydration on the skin’s surface layers.
  • Given the bigger molecule size of lactic acid than glycolic acid (another alpha hydroxy acid), lactic acid is less irritating and hence more suitable for those with more sensitive skin.

When using lactic acid products and other AHAs, it is critical to use a broad-spectrum sunscreen with an SPF of 30 or higher to protect your skin from the sun’s rays. This is because AHAs can cause your skin to become more sensitive to the sun.

Benefits of Niacinamide

Niacinamide is a type of vitamin B3 that offers a variety of skin-friendly benefits.

  • Niacinamide increases collagen synthesis and the production of proteins like keratin, involucrin, and filaggrin, which helps to enhance the appearance of skin firmness and elasticity while also reducing the appearance of wrinkles and fine lines.
  • If you have hyperpigmentation, blotchiness, sallowness, or discoloration on the face, niacinamide is an excellent ingredient to use because it can help reduce the look of these disorders by inhibiting melanin (pigment) formation.
  • Niacinamide increases skin barrier function by decreasing transepidermal water loss and boosting ceramide synthesis, free fatty acids, and cholesterol levels in the skin. A robust skin barrier helps in the retention of moisture and the protection against environmental irritants.
  • Niacinamide is an anti-inflammatory that has the ability to control sebum/oil production in the skin as well as reduce the appearance of pores, making it an excellent choice for those who have oily or acne-prone skin. This 8-week research discovered that a 4 percent niacinamide gel was just as efficient in treating acne as a 1 percent clindamycin gel.
  • Because of the antioxidant properties of niacinamide, you’re also preserving your skin from environmental stresses that can cause aging over time.
  • Niacinamide promotes cell turnover, which results in brighter and more attractive skin.

Can Lactic Acid and Niacinamide Be Used in the Same Skincare Routine?

How to use lactic acid and niacinamide together? While niacinamide and lactic acid can both be used in the same skincare routine, there are several procedures that must be followed to get the optimum results. When it comes to mixing niacinamide with lactic acid, it all basically comes down to pH, which quantifies how acidic or basic a solution is.

The pH scale ranges from 0 to 14, and water has a pH of 7.0, which is considered neutral. The pH of our skin typically ranges between 4.7 and 5.75. Exfoliating acids such as lactic acid are typically formulated with a pH of 3-4, while niacinamide products are typically prepared with a pH ranging from 5.0 to 7.0.

Because lactic acid and niacinamide have pH ranges that are distinct from one another, you’ll need to give some time between using these actives if you wish to utilize them in the same skincare routine.
