FAQ

Genuine products, and why buy from us

Q1. How do I know products from this store are genuine?

Email mediicosmetics@gmail.com with your order number and we will check the item for you.

Q2. I saw the same product cheaper somewhere else. Why buy from the official store?

Products sold outside the authorized channel may well be genuine, but we cannot vouch for them: we do not know how they were stored, how long they have been sitting in transit or in a warehouse, or whether the batch was prepared for the Hong Kong market. Buying from the official channel means you know exactly what you are getting: Korea-direct batches, proper storage from factory to your door, bilingual HK labelling, a real 14-day return policy, and local customer service that answers within a business day. That protection is part of what the price covers.

Q3. This store is new to Hong Kong. Why should I trust you?

Fair question. The brand is not new: OxygenCeuticals started as a professional line used in aesthetic clinics before it became available to consumers. The Hong Kong store is new, so we would rather show you than tell you. We are Medii Technology HK, with a real office in Tsim Sha Tsui East (Office 502, 5/F, Tower 1, South Seas Centre, 75 Mody Road), and an in-person returns option if you prefer to deal with us face to face. Ask us anything before you order.

Q4. Is it worth the price?

Use our product guide or email us with your skin type and current routine. We will recommend honestly, including when a product is not the right fit.

Q5. Will it actually work for my skin?

Use our product guide or email us with your skin type and current routine. We will recommend honestly, including when a product is not the right fit.

Q6. What makes OxygenCeuticals different from other Korean skincare brands?

OxygenCeuticals started as a professional brand: its formulas were used in aesthetic clinics before they became available to consumers. This heritage matters because the efficacy standard was set by professional-use requirements, not consumer marketing.

The brand's core technologies (oxygen delivery, ACELL-300 complex, Ceutisome encapsulation) are not common in mass-market Korean skincare. They represent a more technical approach to how actives are formulated and delivered.

In terms of texture, everything is designed to be clinic-functional in Hong Kong conditions: lightweight enough to wear in humid summers, effective enough that you notice the difference.

Delivery

Q7. Where does my order ship from, and how long does delivery take?

Items stocked in Hong Kong ship from our HK warehouse via SF Express and typically arrive within 2-3 business days. A small number of items in the full catalog are imported to order through OxygenCeuticals' official US distribution; these are marked on the product page and take 7-14 days. You will receive a tracking number once your order is dispatched. Deliveries pause during Typhoon Signal No. 8 or above and black rainstorm warnings, and resume the next working day.

Q8. Is there a free shipping threshold?

Yes. Free shipping on orders over HKD $400. For orders below that, a flat HKD $30 SF Express delivery fee applies. We deliver to every district and outlying island (Cheung Chau, Lamma, Peng Chau, Discovery Bay, South Lantau) at the same flat rate.

Q9. Do you ship outside Hong Kong?

We sell within Hong Kong only. OxygenCeuticals is distributed market by market through authorized regional distributors, and Medii Technology HK is the authorized distributor for Hong Kong. Because each market has its own authorized distributor, we do not ship internationally or to Mainland China.

Payment

Q10. What payment methods do you accept?

We accept:

Credit and debit cards (Visa, Mastercard, American Express, UnionPay)
Apple Pay and Google Pay
Shop Pay
PayPal

More local options (FPS, AlipayHK) are coming soon. All payments are processed securely at checkout; we never see or store your card details.

Returns

Q11. What is your return policy if I change my mind?

Email mediicosmetics@gmail.com with subject Return Request and your order number. Include the product and whether you prefer mail-in or in-person return.

Q12. What if my order arrives damaged, or the wrong item arrives?

Email photographs and your order number to mediicosmetics@gmail.com within 48 hours of delivery.

Using the products

Q13. I have sensitive skin. Are these products safe to use?

Several products in the OxygenCeuticals range are specifically designed for sensitive and reactive skin:

Couperose Fluid: formulated for redness-prone and reactive skin. Fragrance-free.
Skin Barrier Ato Cream: skin-irritant patch tested, suitable for sensitive skin including post-procedure use.
Cryogenic Activator: Primary Irritant Patch Tested (PIPT), suitable for all skin types including sensitive skin.
Moisture Aqua Serum: alcohol-free, suitable for sensitive skin.

As with any new skincare product, we recommend a patch test before first use, particularly if your skin is currently reactive or compromised.

Q14. I have oily or combination skin. Will these products work for me?

Yes. The OxygenCeuticals range is particularly well-suited to combination and oily skin. Most formulas are fluid or water-based, designed to deliver hydration without heaviness.

Hong Kong skin tends to be oily on the surface and dehydrated underneath (externally oily, internally dry). The Moisture Aqua Serum and Acell-300 Fluid address exactly this pattern: hydration that absorbs cleanly without sitting on top of the skin.

Q15. What order should I use these products in?

A general routine using OxygenCeuticals products:

Morning:

Purifying Foaming Wash (or your existing cleanser)
Cryogenic Activator (mist, 15-20cm from face, allow to absorb)
Serum or fluid: Moisture Aqua Serum / Acell-300 Fluid / Couperose Fluid (depending on skin type)
TP Sun Guard SPF50 (final step before going outside)

Evening:

Purifying Foaming Wash (or your existing cleanser)
Cryogenic Activator (optional, effective as a prep step any time of day)
Serum or fluid
Skin Barrier Ato Cream (if using, as final step)

For intensive steps (Ceutisome Hydrating Fusion Shot, i-Fill Ceuti-Shot programme), follow the included instructions; these are used 2-3 times per week, not daily.

Q16. What is an ampoule, and how is it different from a serum?

An ampoule is a more concentrated version of a serum, used as a short intensive course rather than a daily staple. In our range, Ceutisome Hydrating Fusion Shot and i-Fill Ceuti-Shot are ampoule-format products: use them 2-3 times a week or as a programme, in the same routine position a serum would sit (after mist or toner, before cream).

Q17. Can I use multiple OxygenCeuticals products together?

Yes. The products are designed to work as a system. The Cryogenic Activator specifically functions as an absorption primer that improves how the skin takes up whatever is applied next. If layering two serums or fluids, apply from thinnest to thickest texture, and allow each step to absorb before the next.

Q18. How do I use the Cryogenic Activator correctly?

Hold the bottle 15-30cm from your face and mist evenly. Allow 30-60 seconds to absorb before applying the next product. Do not rub in. It can also be used throughout the day as a refreshing mist: over makeup, at your desk, after time outdoors.

Q19. Are OxygenCeuticals products suitable for use after aesthetic procedures (laser, IPL, chemical peel, etc.)?

The brand has a professional post-procedure heritage and several products are commonly used in post-treatment protocols at clinics.

Products suitable for post-procedure use include:

Cryogenic Activator: used in professional oxygen facial protocols, calming and refreshing
Skin Barrier Ato Cream: designed for compromised and post-procedure skin
Couperose Fluid: suitable for post-treatment redness and reactivity
Moisture Aqua Serum: alcohol-free, lightweight, non-irritating

Always follow the specific aftercare instructions given by your clinic. If in doubt about introducing any new product after a procedure, check with your practitioner first.
