Nighttime skincare routines are often designed to help the skin repair and renew itself. As we sleep, the skin enters a regeneration phase, making evening treatments especially important for people with mature skin, dull complexion, or fine lines.

One DIY ingredient that frequently appears in natural beauty routines is baking soda (sodium bicarbonate). Some people claim it can exfoliate the skin, brighten the complexion, and reduce the appearance of dullness overnight.

But does baking soda really improve skin health, especially for aging skin? Let’s take a closer look at the potential benefits, risks, and safer ways to approach nighttime exfoliation.

What Is Baking Soda in Skincare?

Baking soda is an alkaline compound commonly used in cooking and household cleaning. In skincare, it has been used in DIY treatments as a physical exfoliant, meaning it helps remove dead skin cells from the surface of the skin.

When used in small amounts, its fine particles can temporarily smooth the skin by clearing away surface buildup.

However, dermatologists caution that baking soda can be too harsh for regular facial use, especially on delicate or mature skin.

Why Nighttime Is Important for Skin Renewal

The skin naturally repairs itself while you sleep. During the night:

• Cell turnover increases

• The skin barrier begins to repair itself

• Skincare ingredients penetrate more effectively

Because of this process, nighttime routines often include cleansing, hydration, and gentle exfoliation to remove dead cells and improve skin texture.

For mature skin, exfoliation can help address:

• Dullness

• Uneven skin tone

• Fine lines

• Rough texture

But the key word is gentle.

Possible Short-Term Benefits of Baking Soda for Skin

Some DIY beauty enthusiasts use baking soda occasionally for surface exfoliation.
