FAQ

What’s Freeze-drying technology?

Freeze-drying, is the force behind Megadose® advanced performance. It’s one of the most effective methods to maintain the ingredients’ original structure over long periods of time, meaning they get to work with full power when delivered to your skin. This method has been used for 50+ years by the outer-space and pharmaceutical industry to create vaccines, preserve perishable materials and make their transport easy.

What makes Megadose® better than traditional skincare?

The concentrated nature of Megadose® allows it to work more efficiently for your skin with less everything. By removing water, we removed the need for preservatives, bulky packaging and any extras your skin or the Planet don’t need (but a liquid formula does!). Megadose® tablets are formulated with dermatologists, developed and produced with a pharma lab in France to deliver science-backed performance paired with the highest level of safety and quality control. Take your routine to-go, wherever and whenever you need without the TSA-headache. Yes, you can actually take Megadose® to Space. Now you just have to figure out how to get there.

What type of water should 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.

Do I have to use water to dissolve Megadose®?

Nope! You can use your favorite hydrating water-based product — mist, toner, essence, serum or lotion. 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.

Can I mix different Megadose® tablets together?

Yes...with caution! You can mix any Megadose® tablet together beside our HPR-Retinoid 0.3%, which should be applied on its own layer. We recommend layering them at first use, to ensure there is no irritations. Keep in mind less-is-more: we suggest using a maximum of 2 different tablets per routine (AM &/or PM) that target your top 2-3 skin concerns to avoid any dilution effect or irritation when using too many actives at the same time.

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.

    perfect for me and the hubby

    I started using this and then my husband wanted in when he saw the change on my skin texture after a few days!! We've both been on our 3rd month now and we're super happy with the results. The hubby gets so many compliments on his skin from our friends (which never happend before)!! I'll be trying the Alpha Arbutin to try to get rid of my acne scars.

    yes yes and yes

    It's effective, sustainable and easy to use. You get used to the process after a couple time doing it, to find the right amount of water you like. I struggle with clogged pores/oily skin and it's been effective so far after finishing my first pack. I'm receiving my refill soon so we'll see if it improved even more!

    my aging skin loves it!

    This serum has become my secret to bring back radiance to my skin. It works great when combined with the Peptides one thanks to the nice customer service recommendation! I do Niacinamide in my morning routine and Peptides at night.
