FAQ

WE’VE DONE OUR RESEARCH

Will the serum work for sensitive skin?

PlusMinus

Yes. A3O™ was designed to be a smarter, more stable alternative to Vitamin C — with none of the irritation, stinging, or sensitivity many people experience with traditional actives. It’s tested safe for sensitive skin and post-procedure use.

How often should I use the serum?

PlusMinus

Apply A3O™ Elemental Serum morning and night to clean, dry skin. A3O™ is gentle enough for daily use — even for sensitive skin.

For optimal absorption and hormonal support, we recommend taking Inner Dose™ in the morning with food. That said, it’s safe to take at any time that works for your routine.

Why pair the serum with a supplement?

PlusMinus

For optimal results, pair with our Inner Dose™ Daily Skin Supplement to target aging from the inside out. You can also layer with your favorite moisturizer or SPF.

WHO ARE YOUR PRODUCTS FORMULATED FOR?

PlusMinus

Elm is designed for real skin — including sensitive, aging, hormonal, or inflammation-prone. Our formulas are clinically tested to work across a wide range of tones, textures, and needs.

WHEN CAN I EXPECT TO SEE RESULTS?

PlusMinus

Most users begin to notice visible changes in clarity and tone within 2–4 weeks, with continued improvement over 8–12 weeks. Consistency is key — internal triggers of aging take time to regulate.

Can I take this at any time of day?

PlusMinus
