Which one is right for you?

Choose Avobenzone if…

Choose a comfortable broad-spectrum sunscreen; avobenzone is one possible UVA filter.

You want a lightweight chemical sunscreen
UVA protection without white cast
Daily wear under makeup

Choose Licorice Root Extract if…

Consider as an optional pigment ingredient; independent clinical evidence is limited.

Mild uneven tone
Sensitive skin that dislikes stronger pigment actives
Modest expectations

Often combined

Can you use both?

Sunscreen is essential when treating dark spots. Apply licorice first, then sunscreen.

Botanical pigment-targeting mixture

What it does

Provides UVA coverage within tested sunscreen formulas.

Some licorice-derived compounds are studied for uneven pigmentation.

Best for

Sunburn; Melasma; Wrinkles and Fine Lines

Melasma; Uneven Skin Tone

Studied concentrations

Choose by broad-spectrum SPF and water-resistance claims, rather than filter percentage alone.

Extracts are not standardized; the cited small study used a liquiritin cream.

When to use

Each morning and before sun exposure.

On the schedule specified for the product or prescribed treatment.

Time to results

Protection with correct application; prevention continues over time

Usually assessed over 8–16 weeks

Irritation

Can sting the eyes or irritate some skin; stop for a persistent rash.

Botanical extracts can cause allergy or stinging; check the complete formula.

Sensitive skin

Choose a simple formula and test a small area first. Individual tolerance matters more than an ingredient’s reputation for being gentle.

Choose a simple formula and test a small area first. Avoid actively inflamed or broken skin unless the product is specifically directed for it.

Available

Prescription or cosmetic status depends on the active, formula and country; check the label.

Sunburn

A tested broad-spectrum sunscreen protects against UV exposure; avobenzone supplies UVA coverage.

Flat tan patches with soft irregular edges across the forehead and upper cheek of an adult with light skin, the surface completely smooth.

Melasma

Broad-spectrum sun protection supports pigment care; it does not clear melasma alone.

Wrinkles and Fine Lines

Regular sunscreen helps prevent further photoaging.

Inflamed acne on light skin. The spots sit in a patch of pink, and the ring of redness around each one is easy to see. A few have a yellow-white head, and the skin between them is dry and flaking.

Strengths and forms

Concentrations

Avobenzone is a UVA filter with a U.S. monograph maximum of 3%. Its performance depends on the full sunscreen formula, not the percentage alone.

3%

U.S. sunscreen ceiling

A permitted maximum. This number is not the product’s SPF or a stand-alone measure of UVA protection.

Choosing a strength: Choose a finished, tested broad-spectrum sunscreen rather than a target avobenzone percentage.

Higher strengths: More of one filter is not a substitute for tested UVA and UVB protection or correct application.

Formula matters: Avobenzone needs an appropriate stabilized formulation and complementary UVB protection. Do not add raw filters to skincare.

Licorice root extract contains multiple compounds, including liquiritin and glabridin. Whole-extract percentages do not reveal the dose of these individual compounds.

Choosing a strength: Look for the named extract or purified compound and evidence for the finished product.

Higher strengths: There is no established universal percentage range or proof that higher whole-extract concentrations improve pigmentation.

Formula matters: A small study of liquiritin cannot establish a recommended strength for every licorice extract, species, or formulation.

Safety and sensitive skin

Common reactions

Can sting the eyes or irritate some skin; stop for a persistent rash.

Botanical extracts can cause allergy or stinging; check the complete formula.

When to stop

Stop for persistent burning, swelling, blistering or a new rash. Seek urgent care for breathing difficulty or a severe allergic reaction.

Important limits

Do not use a cosmetic product as a substitute for diagnosis of an unexplained, changing or persistent skin problem.

Pregnancy

Sunscreen use is encouraged in pregnancy; avobenzone is generally considered acceptable. Mineral filters are an alternative if you prefer.

Data are limited; ask the clinician managing your pregnancy.

How it works

In the skin

On the skin. The finished product delivers avobenzone in a particular vehicle.

Entering skin. Below 500 Da, but sunscreen works in its surface film. Human studies show some absorption; size alone does not establish absorption, harm or protection.

Conversion. No activation step is established as necessary for its intended topical role.

Skin response. Absorbs UVA energy; stability and combination with UVB filters determine the finished product’s protection.

Additional effects. Proposed pathways do not establish a measured depth of delivery or clinical benefit beyond the studies cited.

On the skin. The finished product delivers licorice root extract in a particular vehicle.

Entering skin. No single molecular mass. The 500 Da guideline cannot be applied to this whole ingredient family or mixture.

Conversion. No activation step is established as necessary for its intended topical role.

Skin response. Compounds such as liquiritin and glabridin have different pigment-related actions; they are not interchangeable extracts.

Product examples

Avobenzone

Jack Black Intense Therapy Lip Balm SPF 25 — Avobenzone paired with octinoxate, which destroys it. Real UVA protection is likely well below the label.
Supergoop! PLAY Lip Balm with Acai SPF 30 — Properly photostabilized, so better UVA cover than Jack Black's — and fragranced, while selling itself as clean.

Common questions

Avobenzone:What should I choose avobenzone for?

Choose a comfortable broad-spectrum sunscreen; avobenzone is one possible UVA filter.

Avobenzone:How strong is the evidence?

A randomized trial supports regular sunscreen use for photoaging prevention, not avobenzone alone. An FDA absorption study measured systemic exposure under study conditions; absorption alone did not establish harm.

Licorice Root Extract:What should I choose licorice root extract for?

Consider as an optional pigment ingredient; independent clinical evidence is limited.

Licorice Root Extract:How strong is the evidence?

A 20-woman split-face study tested a specific liquiritin cream for four weeks with sun protection. It does not establish that all licorice extracts treat melasma or rosacea.
