Lumen Skin FAQs
15 answers for common beauty questions. Open chat if you need something that isn’t listed here.
What is Lumen Skin?
Lumen Skin makes barrier-first skincare for humid climates — lightweight textures, fragrance-optional formulas, and clear ingredient notes. We are not a medical provider.
Is the serum safe for sensitive skin?
Our Calm Barrier Serum is formulated without fragrance and essential oils and is suitable for many sensitive-skin routines. Patch test on the inner arm for 24 hours. If you have a diagnosed condition, ask a dermatologist before use.
What’s the difference between the gel and cream cleanser?
Gel cleanser is a low-foam daily wash for normal to combination skin. Cream cleanser is richer and better for dry or air-conditioned skin. Both are pH-balanced and rinse clean without a tight feel.
Which products are fragrance-free?
Calm Barrier Serum, Cream Cleanser, and Mineral SPF 40 are fragrance-free. The Citrus Mist and Body Silk contain a light scent — listed on each product page.
Can I use niacinamide with your vitamin C?
Yes. Use vitamin C in the morning after cleansing and before moisturizer/SPF. Use niacinamide serum at night, or both in the same routine if your skin already tolerates them. Introduce one new active at a time.
Do you ship to Japan?
Yes. Japan orders usually arrive in 5–10 business days after dispatch. Import duties may apply and are the customer’s responsibility when not collected at checkout.
Which countries do you ship to?
Singapore, Malaysia, Indonesia, Thailand, Philippines, Vietnam, Hong Kong, Taiwan, Japan, and South Korea. We do not ship aerosols or liquids over 100ml by air to every destination — checkout will block unsupported carts.
Can I return an opened bottle?
Unopened products can be returned within 30 days. Opened products can only be returned if defective or if we sent the wrong item — contact us within 7 days with a photo. For hygiene reasons we can’t accept opened returns for change-of-mind.
How do I build a simple routine?
Morning: gel or cream cleanser → serum → moisturizer → SPF. Night: cleanser → serum → richer cream if needed. Chat can suggest a kit based on dryness, oiliness, or sensitivity — not for diagnosing skin disease.
Are you cruelty-free and vegan?
We are cruelty-free. Most products are vegan; the Lip Treatment contains beeswax and is labeled as such on the page.
What is your shelf life after opening?
See the PAO symbol on each pack (usually 6M or 12M). Store away from direct sun. Discard if color or smell changes unexpectedly.
Do you offer samples?
Orders over SGD 60 include 2 deluxe samples while stocks last. We can’t honor specific sample requests in chat when inventory is low.
Can pregnant customers use your products?
We don’t give medical advice. Ingredients are listed on each page — please check with your doctor. We avoid retinol in the core line; always verify the full INCI list for your situation.
How long does shipping take in Singapore?
In-stock SG orders usually arrive in 1–3 business days. Same-city express is available at checkout before 2pm on weekdays.
When should I talk to a human?
Ask for a human for allergic reactions, customs holds, wholesale, or refunds for defective opened products. Routine and ingredient questions are usually handled in chat from this FAQ.
Still stuck?
Open the chat — this agent should answer from this Help Center. If it needs billing, legal, or account changes, ask it to hand off to a human.
