Vitamin C Is Too Harsh for You? This Is What Dermatologists Recommend Instead for Dark Spots

Licorice root contains glabridin and liquiritin, which tackle dark spots from two different directions. Glabridin stops melanin from forming. Liquiritin breaks down melanin that has already formed. Along with Glycyrrhizin and Licochalcone A, they fade existing dark spots and prevent new ones, without the irritation that traditional vitamin C causes on sensitive skin. Results take 8 to 12 weeks but are well sustained and safe for daily use.

Introduction

You tried a vitamin C serum. But your skin started stinging, went red, and the dark spots stayed exactly where they were. So you stopped. It does not mean your skin cannot fade dark spots. The problem is that vitamin C, in its most effective L-ascorbic acid form, does not suit most sensitive skin types.

This is where Licorice root is what dermatologists increasingly recommend for sensitive skin dealing with hyperpigmentation. It works on dark spots through a completely different pathway, at a pH your skin actually tolerates, with anti-inflammatory benefits. Continue reading to learn more about licorice root extract and why dermatologists recommend this over vitamin C.

Why Vitamin C Does Not Work for Every Skin Type?

Vitamin C in its most effective form, L-ascorbic acid, needs a very low pH level, around 3.5, to stay stable and absorb into the skin. Now your skin has its own natural pH, which sits between 4.5 and 5.5. That is the slightly acidic range your skin needs to stay balanced, healthy, and protected. The problem is the gap between 3.5 and 4.5. When something significantly more acidic than your skin's natural environment is applied, your skin reads it as a threat rather than a treatment.

For skin that is already reactive or barrier-compromised, that level of acidity triggers a stress response. The result is stinging, redness, and sometimes a worsening of the very dark spots you were trying to treat, because the irritation itself signals your skin to produce more melanin.

What Is Licorice Root and How Does It Work on Dark Spots?

Licorice root has been used in skincare for centuries. What is interesting is that modern science has confirmed exactly why it works. Licorice root comes from the plant Glycyrrhiza glabra. It contains several active compounds, but four of them do the most work on dark spots.

Glabridin

Glabridin targets tyrosinase, which is the enzyme that tells your skin to produce melanin. When tyrosinase activity slows down, your skin produces less excess pigment.

What makes it stand out is how selective it is. It goes after pigment specifically, without interfering with how your skin cells function otherwise. In vitro studies, which are lab tests on skin cells, have shown glabridin to have a skin-lightening effect up to 16 times greater than hydroquinone, one of the most widely prescribed skin-lightening agents, without the harsh side effects.

Liquiritin

Most brightening ingredients only prevent new pigment from forming. Liquiritin does the other job. It breaks down the melanin that has already built up in your skin and helps disperse it. While glabridin stops new spots from forming, liquiritin fades the ones already visible.

Glycyrrhizin

This is the primary anti-inflammatory compound in licorice root. It reduces redness and calms reactive skin conditions like eczema and rosacea. That is why licorice root extract feels gentle, even on the most sensitive skin types.

Licochalcone A

An antioxidant with mild antibacterial properties, licochalcone A is useful if you deal with both dark spots and breakouts. It reduces the bacteria that trigger acne, which reduces the post-inflammatory hyperpigmentation that those breakouts leave behind.

All four of these compounds work on dark spots without disrupting how your skin naturally functions. That is what makes licorice root so well-suited for sensitive skin.

If you want licorice root working alongside vitamin C in one stable, sensitive-skin-friendly formula, Kayura's Karma Boost Vitamin C and Antioxidant Serum brings both together. It contains glabridin-rich licorice root extract as part of its phyto-blend, paired with 3-O Ethyl Ascorbic Acid, plus niacinamide, resveratrol, and vitamin E. All four antioxidants are delivered through a liposomal and micellar system, which means they are wrapped in molecules your skin can actually recognize and absorb into the deeper layers. You won't find this unique combination in any other serum.

What Does Licorice Root Do for Sensitive Skin?

Dark spots do not appear without a trigger. And this trigger is almost always inflammation. It occurs due to a breakout, sun exposure, friction, or a product reaction. The inflammation signal tells your skin to overproduce melanin as a kind of protective response. The result is the dark spot that stays long after the original irritation has healed.

Here is what licorice root does for sensitive skin instead:

Works on the Root Cause

Licorice root's antioxidant compounds reduce oxidative stress triggered by UV and environmental exposure. Oxidative stress is what sets off the inflammatory cycle that causes dark spots to form repeatedly. By reducing that trigger, licorice root does not just fade existing marks. It stops new ones from forming.

Calms Inflammation

Most brightening ingredients either calm the skin or fade pigmentation. Licorice root does both at the same time. Glycyrrhizin actively reduces inflammation, while glabridin and liquiritin work on the pigmentation underneath.

Keeps Skin Hydrated

Glycyrrhizic acid, one of the naturally occurring compounds in licorice root, helps your skin hold onto moisture and reduces water loss over time. This is why licorice root feels comfortable with daily use. It never strips or dries the skin the way some brightening actives do over repeated use.

Reduces Breakout-Related Pigmentation

Licochalcone A has antibacterial properties that reduce the acne-causing bacteria responsible for breakouts. Fewer breakouts mean fewer instances of post-inflammatory hyperpigmentation.

How to Use Licorice Root in Your Routine?

Small details in how you apply it make a bigger difference in the result you get from using that skin care product. Here's the routine you can follow:

• Cleanse first. Any leftover sunscreen, makeup, or daily buildup blocks actives from absorbing. Start clean so licorice root can actually reach the skin it needs to treat.
• Apply to damp skin. Do not wait for your face to fully dry after cleansing. Damp skin absorbs actives faster and more evenly.
• Press in, do not rub. Use your fingertips to gently apply and press the serum into your skin. Rubbing creates friction, which triggers the same inflammation that causes dark spots.
• Moisturize straight after. Apply your moisturizer while the serum is still slightly damp on your skin. This locks the active in and gives your barrier the hydration it needs.
• SPF every morning, no exceptions. UV exposure triggers new melanin production daily. Without SPF, you are fading spots that keep coming back.

Kayura's No Rays, Thanks Mineral Sunscreen SPF 50 PA++++ contains Nut Grass extract alongside 15% non-nano zinc oxide, which makes it one of the most well-paired morning steps for anyone actively treating pigmentation.

The Takeaway!

Licorice root is not the fastest ingredient for dark spots. But for sensitive skin, it is the most reliable one. No stinging. No flare-ups. No setbacks that undo weeks of progress. Give it 2 to 4 weeks and your skin tone starts to even out. By weeks 6 to 8, existing spots begin to visibly lighten. At 10 to 12 weeks, you start seeing the kind of clarity that actually holds.

Kayura's clinically tested sensitive skin range is built around exactly this kind of gradual, supported recovery. Every formula is fragrance-free, non-comedogenic, and made for skin that needs results without the irritation. Explore Kayura's sensitive skin range and find formulas built for your skin!
