Licorice: The Complete Nopal Life Guide

Glycyrrhiza glabra: Licorice and its botanical components

Licorice (Glycyrrhiza glabra) is a traditional plant from the Fabaceae family whose roots contain a remarkable diversity of botanical compounds. In cosmetics, it is glabridin that attracts the most attention from formulators. This flavonoid represents a significant portion of the isoflavonoids in licorice extract and is traditionally valued for helping to enhance the appearance of skin radiance and uniformity, as well as for its soothing comfort and antioxidant action. Licorice also contains glycyrrhizic acid, a botanical compound known for its soothing action on sensitive skin. This botanical richness explains licorice's place among the active ingredients of choice in routines dedicated to skin radiance and uniformity.

Licorice and the appearance of spots

Appearance spots — linked to sun exposure, hormonal variations, or marks left by previous imperfections — correspond to areas where the complexion appears darker and uneven. Licorice glabridin is traditionally valued for helping to reduce the visible appearance of these spots and promote a more even-looking complexion. It is especially prized for helping to improve the appearance of localized areas, without altering the skin's natural tone. To support this appearance-enhancing effect, combining it with gentle exfoliating active ingredients like AHAs (glycolic acid, mandelic acid) helps to reveal smoother and brighter-looking skin. Licorice is thus part of a global cosmetic approach to radiance and uniformity, an essential complement to good photoprotection.

Licorice and comfort: a leading botanical soother

Beyond its benefits for skin radiance, licorice is a highly valued botanical skin soother. Glycyrrhetinic acid, one of its molecules, is traditionally recognized for helping to soothe the appearance of redness and sensations of discomfort. For marks left by previous imperfections, often accentuated by repeated discomfort, licorice is valued for helping both skin comfort and the appearance of complexion uniformity. This dual dimension makes it a particularly interesting active ingredient for skin that easily shows marks.

Mistakes to avoid when using cosmetic licorice

Licorice is a highly valuable active ingredient, but certain mistakes can limit its benefits. The first mistake is expecting results in a few days: the appearance of the complexion evolves gradually, and visible effects on spots are generally noticeable after 4 to 8 weeks of daily use. Any premature interruption compromises the appearance outcome. Second mistake: neglecting sun protection. Without SPF, UV rays continuously affect the skin and negate the appearance benefits of licorice. A minimum SPF 30 applied every morning is essential. Third pitfall: using overly high concentrations, thinking that the more concentrated it is, the more effective it is. Beyond 2% glabridin, the risk of discomfort increases without a proportional gain; formulations at 0.5-1% are the most well-documented. Fourth mistake: applying licorice products to severely damaged skin or wounds. Fifth point: do not confuse cosmetic licorice with edible licorice — when applied externally at cosmetic concentrations, the effects of oral use are not a concern.

Formulations and combinations for an even-looking complexion

To get the most out of licorice in cosmetics, formulation and active ingredient combinations play a crucial role. Glabridin is a fat-soluble active ingredient: it must be integrated into the oil phase of the formulation or in a suitable solubilizing system to ensure its stability and dispersion. Light emulsion serums are the ideal vehicle for combining it with complementary active ingredients. Niacinamide (vitamin B3) is licorice's partner of choice: it helps to unify the appearance of the complexion, provides a soothing action, and improves the appearance of skin texture. Azelaic acid is also a good complement for promoting a clear complexion. For stubborn appearance spots, combining it with a retinoid (retinol or retinal) at night helps to reveal fresher-looking skin. Nopal Life pure prickly pear seed oil, rich in vitamin E and beta-carotene, can be applied as a complement to provide comfort and antioxidant protection. Consult the Nopal Life skin guide for complete spot care protocols.

Nopal Life Routine for an Even and Radiant Complexion

A radiance and uniformity routine incorporating licorice revolves around a consistent morning and evening approach and essential SPF. In the morning, after gentle cleansing, apply a serum containing glabridin and niacinamide to clean skin. Allow it to penetrate for 2 to 3 minutes before applying a light moisturizer, then a minimum SPF 30 — without UV protection, all the appearance benefits of licorice are lost. In the evening, after thorough makeup removal, apply a gentle exfoliating serum (mandelic or glycolic acid at a low concentration) two to three times a week to help reveal radiance. On other evenings, a nourishing treatment like pure prickly pear seed oil as a final step restores skin comfort and provides beneficial nighttime nourishment. Once or twice a week, a licorice and pink clay mask helps to unify the appearance of the complexion without aggression. This protocol, followed regularly for 8 to 12 weeks, helps to reveal a more even and radiant-looking complexion.
