Where It Fits in Your Routine
There are no ingredients known to conflict with our peptides. One rule keeps everything working:
Example Routines
Morning Routine
Face wash → Face Tonic → Sunscreen
Optional: add vitamin C or hyaluronic acid between Face Tonic and sunscreen
Night Routine
Face wash → Face Tonic → Moisturizer
Optional: add retinol serum or other products
Using both tonics? Face Tonic and Hair Tonic together take under 60 seconds a day.

Good to Know
Morning or night?
Either works, and both is fine. Consistency matters more than timing.
Can I put moisturizer over it?
Yes, and you should if moisturizer is part of your routine. Tonic first, 30-60 seconds to absorb, then moisturizer or anything else.
Do I rinse out the Hair Tonic?
No. It is a leave-in. Apply, massage it in, style as usual.
What about sensitive skin?
Our formulas contain no parabens, sulfates, silicones, or artificial fragrances. As with any new product, patch test a small area first, and check with a dermatologist if you have a known skin condition.
How long does a bottle stay good?
Use within 6 months of opening. For external use only. Avoid contact with eyes and discontinue if irritation occurs.
