A lightweight toner that gently exfoliates without disrupting the skin barrier - it leaves the skin feeling clean and refreshed instead of sticky and stripped (commonly associated with BHA-based toners)

SMELLS LIKE

Nothing

How do I use this toner?

After cleansing, apply over clean face and neck with a cotton pad or fingers. Do not rinse. Always apply SPF during daytime.
Tip: This toner contains a high concentration of salicylic acid, suitable for sensitive skin, but it is always recommended to start slowly when adding an exfoliant to your skincare routine and increase frequency of use once your skin is acclimated.

When should I use this toner in my skincare routine

This toner should be applied after cleansing and before serums and moisturizers. This allows the toner to effectively exfoliate and prep your skin for the next steps in your routine. Tip: Layer products in order of thickness (from thinnest to thickest).

Can I use this toner everyday?

Yes, FSA2.0 can be used daily even if you have sensitive skin. However, it is always recommended to start slow with exfoliants and increase frequency of use based on skin tolerance.
To maximize tolerance, we recommend using a hydrating serum + moisturizer after the toner and avoid using exfoliants (AHA, BHA, retinol) on the same day.
If you're not sure about your skin tolerance yet, limit initial use to once or twice a week, gradually increasing frequency to every other day, then everyday once your skin is acclimated. Always apply SPF during the daytime.

Is it safe to use this toner on sensitive skin?

Yes, most people with sensitive skin can use this toner safely.
This toner is formulated with flavonoids to help combat any inflammation while optimizing for deep exfoliation. It has also been tested on sensitive skin under dermatologist supervision as part of clinical RIPT to ensure compatibility with all skin types. However, given the high concentration of the active, we recommend patch testing before starting use and starting slow, increasing frequency of use as your skin gets acclimated.

Can this toner be used with other actives (vitamin C, retinol/retinoids etc.)?

Yes, this toner can be paired with other active ingredients depending on your skin tolerance. To maximize skin compatibility:

  • Start slow and observe how your skin reacts, increasing frequency of use once your skin is acclimated.
  • Avoid using exfoliants (AHA, BHA, retinol) on the same day (alternating nights is recommended).
  • Hydrate before and after active steps to lock in the benefits of the chosen active and protect the skin barrier.

If you’re unsure about pairing active treatments, please consult a dermatologist.

When will I start seeing results after using this toner?

Everyone’s skin is different but based on clinical testing, it is normal to notice benefits (skin hydration and smoothness) immediately and more in as little as 2 weeks. Other longer term benefits like improvement in skin texture and reduction in blemishes may take longer (4 weeks).

Is this cleanser suitable for acne-prone skin?

Yes, 2% salicylic acid is recommended for acne-prone skin. This toner helps unclog congested pores while removing excess sebum and dead skin cells to help prevent blemishes and breakouts.

Can I use this toner with other acne treatments?

Yes, but be cautious when combining products, especially if you're using other active ingredients like benzoyl peroxide or retinol. Overuse of actives can lead to irritation.
It's a good idea to introduce products gradually and monitor how your skin reacts.

Is this toner suitable for dry skin?

Yes, this toner is formulated without alcohol (a common ingredient used as the primary solvent in toner formulas that disrupts and dehydrates the skin barrier) and with flavonoids that act as anti-inflammatory agents to help combat irritation.
This formula has also been tested on dry skin under dermatologist supervision as part of clinical RIPT to ensure compatibility with all skin types.
However, it’s always recommended to properly hydrate the skin after using active-based products to lock in the benefits of the chosen active and protect the skin barrier. Tip: Use a rich moisturizer instead of lightweight gel-based creams after exfoliating to minimize discomfort and maximize skin compatibility.

Is this serum safe to use during pregnancy?

Yes, this serum is considered as safe to use during pregnancy or while breastfeeding. However, if you’re uncertain about using any new skin care product or ingredient, please consult your physician.

How to use

After cleansing, apply over face and neck with a cotton pad or fingers. Do not rinse. Always apply SPF during daytime.
