Which Megadose® is best for me?

Head to our Shop menu to show the best products for your specific skin concern. You can also filter products by Category or Concerns from our Collection Page. Still unsure? Email us at help@onelogy.com, or Chat with us and our of our experts will curate a routine for you.

How do you activate Megadose®?

Activating your Megadose® is as easy as 1-2-3. For a visual guide, view our How it Works page.

1. Unscrew the cap of your 4EVERBTL* and fill with water. Screw cap back on.
2. Peel-off the blister's individual seal and place one tablet in the palm of your hand.
3. Add 5 to 10 drops of water and mix with your fingers until the tablet is fully dissolved .
4. Apply on clean skin like any serum! Finish off with a moisturizer to lock it in.

*One free reusable dropper bottle is provided with every order of Megadose®. Already have one? Simply remove it from your cart before checking out.

What type of water can I use to activate Megadose®?

Any type of drinking water! Our team generally prefers to use filtered or mineral water, but tap water also works great if you're already comfortable washing your face with it.

Can I use something else to dissolve Megadose®?

Yes! You can also use your favorite water-based products (mist, lotion, serum, cream...). Keep in mind thick formulas might slow down dissolution time or require extra mixing. Oil-based or highly lipophilic products are to be avoided. Pure oils will not work.

Is Megadose® suitable for sensitive skin?

Yes! All our products are dermatologist tested and formulated to be suitable for all skin types, especially sensitive skin. We conduct 3 separate sensitivity tests with 50 subjects for each product.

If you have questions about your specific skin type or a particular product, reach out to our licensed expert team at help@onelogy.com.

Is Megadose® vegan and cruelty-free?

Yes, we love our furry friends. We're both Leaping Bunny and Vegan Certified. We also vet and only work with vendors who uphold the same standards.

Is Megadose® clean, natural and organic?

Honestly, we hate the word "Clean" and despise "No-No lists". They have become overused marketing concepts that lack true standardized definitions.

At Onélogy, we trust science. For each product, we determine the best option against factors such as effectiveness, bio-availability and environmental impact. This means we use a combination of naturally-derived or synthetic ingredients and even pharma-grade raw materials (meaning 99%+ purity vs 95% for cosmetic grade) depending on the formulas.

To learn more about specific ingredient details, please visit the Ingredient List section on each product page, our Ingredients Page or reach out to us via Email at help@onelogy.com or via our Chat Support if you have skin allergies or sensitivities to certain ingredients, fragrances or dyes.

Is Megadose® safe for pregnancy and breastfeeding?

All formulas are safe to use while pregnant or breastfeeding except for any Megadose® containing a Retinoid, a derivative of vitamin A (like Retinol, Retinal, HPR). Please refer to the Directions on each product's individual page before purchasing. We advise those who are pregnant or lactating to consult their physician prior to using a new skincare product.

If you have questions about a particular product, reach out to our licensed expert team at help@onelogy.com or our Chat Support.

Is Megadose® safe with gluten, soy or nut allergies?

Yes, our products do not contain gluten, soy or nuts. Please consult your primary care doctor if you have any questions around your health.

Do you use any fragrance, dye or essential oils?

In order to make our products suitable for most, we decided to not include any fragrance, dye or essential oil in our products; which are known potential allergens. Some of our Megadose® tablets are colored; this is due to the natural color of their active ingredients in raw form.

How do I layer Megadose® in my skincare routine?

Megadose® is just like your typical skincare serum, only delivered in an initial tablet form before it's activated. We recommend using Megadose® as the treatment step of your skincare routine. This means it should go after cleansers, mists, toners, essences and before your moisturizer, face oils and sunscreen.

Can I mix different Megadose® tablets together in one use?

Depends! With a less-is-more and consistency-over-quantity philosophy in mind, our products are designed to deliver effective daily doses gentle enough for sensitive skin. If you feel confident in what your skin can tolerate and which combinations of actives to avoid, absolutely! Otherwise reach out to our licensed expert team at help@onelogy.com or in our Chat Support, we’re happy to recommend a tailored routine for you.We always recommend doing a small patch test before mixing any tablets together.

How many Megadose® tablets come per box?

Each regular size Megadose® contains 32 tablets (~ about one month supply with one daily application).

Where is Megadose® manufactured?

All Megadose® products are developed and manufactured at a pharmaceutical lab in France. Oui Oui!

Does Megadose® have an expiry date?

As long as tablets remain sealed in their original individual blister, they can be stored for up to 10 years! To make sure you get peak potency out of each tablet, we do recommend using it within 3 years. Once the individual seal is removed, the tablet should be used within a couple days and the same day once activated.

What happens if I accidentally eat a tablet?

As an extra safety measure, all our products are evaluated for cases of accidental ingestion and we found that there is no indication of serious hazard. Consult your physician in case of abnormal symptoms. Just don’t eat it. Keep it out of reach of children and pets.

Is your packaging recyclable or biodegradable?

Megadose® blisters are made in aluminum foil and are fully recyclable in your regular aluminum recycling stream. 4EVERBTL™ is meant to be refilled and reused. However, If you decide you don’t need it anymore, the bottle is readily recyclable after rinsing. Make sure you keep the cap on when throwing out. Paper components are 100% recyclable and biodegradable. It is composed of FSC certified paper, bio-lamination and bio-coating.

For more details, please see our Recycling Guide.
