Introduce Your First MaryenB Serum
A simple start makes it easier to observe your skin response. You do not need to introduce every active ingredient or all six formulas.
Start with one main concern
Compare the cosmetic appearance goals and complete ingredient lists. Check the current product label, consider your experience with active skincare, and choose one formula to introduce. No formula is guaranteed to suit every skin type.
Before full-face use
Try it on a small area of skin before first use, following the product label and its frequency restrictions. A small-area test does not guarantee that irritation will not develop later. Keep the rest of your routine familiar and do not introduce a second new active serum at the same time.
Follow the selected formula’s start
- ANC5 or ANC10: a small amount, starting 2–3 times per week.
- TNA5: 1–2 pumps, starting once daily and adjusting only while comfortable.
- NTZ20: 1–2 pumps, starting once daily or 2–3 times per week.
- RNT: 1–2 pumps, evening only, starting 2–3 nights per week.
- VNC15: a small amount, starting once daily in the morning or evening.
Apply to clean, dry skin and follow with a moisturizer. Use sunscreen during the daytime; RNT directions specify broad-spectrum sunscreen every morning. RNT is not for use during pregnancy or nursing, or while planning pregnancy.
Observe before increasing
Increase use only while your skin stays comfortable. Stop use if irritation occurs. Burning, strong redness, or severe discomfort is a reason to pause, not to add another serum.
Keep skin comfort first
Try it on a small area of skin before first use. Introduce one new serum at a time and keep the rest of your routine simple. Apply to clean, dry skin, then follow with a moisturizer. Use sunscreen during the daytime. Avoid contact with eyes. If your skin feels uncomfortable, stop using it. Do not use an active serum on irritated or compromised skin.
MaryenB products are cosmetics for caring for the appearance of your skin. Feel and results vary from person to person. Results and tolerance vary. Follow the current product label.
