Licorice serum

Choose the licorice serum category based on your goals: brightening and dark-spot reduction, pH balance for sensitive skin, or simple hydration. Consider the brand’s reputation and the formulation type—whitening serums, dark-spot targeted serums, or pH‑balancing formulas—and how they fit with your current routine. Look for well-known options from brands like aichun-beauty, acwell, uncover, and Active, which offer different licorice-based therapies. Also check for key actives such as licorice extract, arbutin, or vitamin C, and always patch-test before regular use.

pH balancing ensures the serum matches your skin’s natural acidity, protecting the barrier and improving ingredient absorption. A licorice serum labeled for pH balancing, often targeting a mild pH around 5.5, helps reduce irritation while making whitening or brightening actives work more effectively. If you use other acidic or alkaline products, space their use and apply licorice serum first, then moisturize and sunscreen to maintain a stable routine.

Yes—beginners should start with a single light licorice serum once daily to test tolerance. Experienced users can layer with moisturizer and sunscreen or pair with compatible actives, introducing one new product at a time. Apply after cleansing and toning, and prefer a daytime application with sunscreen to protect your skin while it adjusts to the formula.

Patch testing and proper layering are essential before regular use. Do a 24- to 48-hour patch test on a small area; if no irritation occurs, apply after cleansing and toning, then seal with moisturizer. In the daytime, follow with sunscreen, and avoid combining with strong acids or irritants in the same routine to minimize risk of irritation.

For targeted dark spots, choose a licorice serum labeled for whitening or one that includes arbutin. Examples include Licorice Root Dark Spot Serum from uncover and an alpha‑arbutin–containing option from Active. For overall brightening, try Licorice Root Whitening Facial Serum from aichun-beauty. Match the choice to your goal: spot correction versus a more uniform glow.

Licorice serums generally suit many skin types, but pick a formula aligned with your skin’s needs, such as sensitive, dry, or oily skin. Store the product in a cool, dry place away from direct sunlight; keep the bottle tightly closed and use within the opened period indicated on the packaging. If you notice irritation or unusual changes, discontinue use and consult a dermatologist.
