Product Description

Product Description:

Experience the pinnacle of skincare innovation with our highest concentration vitamin C metabolite (25%), blended with an elegant organic rose hips hydrosol to combat visible signs of dermal aging, particularly targeting blotchy, uneven skin tone.

This serum boasts an easy-spreading, lubricious texture, ensuring smooth application and prolonged absorption.

Harnessing the potency of a very high concentration of vitamin C metabolite, this formulation effectively fades aging blemishes and pigmentation blotches, restoring skin's natural radiance.

During initial applications, users may notice a gentle sensation of skin warmth, indicative of the serum's active efficacy.


  • Fast acting on key skin receptors
  • Organic rose hips hydrosol
  • Well tolerated vitamin C metabolite
  • Noticeable, visible improvement

Skincare Concerns:

Targeted Skin Type: Uneven pigmentation, age spots, blotchy, and unresponsive skin are C 25 SERUM targets.

Skincare Concerns: Note that any vitamin C topical can quickly generate skin receptor fatigue. Over frequent application will reverse visible benefits. The skin should be ‘surprised’ by this metabolite.

Very high concentrations as found in C 25 SERUM applied one evening per week (observe and adjust) seems to work best.

Aging or youthful skin with uneven pigmentation and blemishes cannot be exfoliated to a more even tone or address unsightly age spots. Where it has lost its vitality and responsiveness new approaches are necessary.

There are ways to recover depleted skin and we encourage you to learn more about skin recovery at REFERENCE TOPICS find especially these topics: REPAIR MODEL and the TRAINING MODEL.

How To Use:


  • Apply C 25 SERUM once or twice (1x-2x) per week, evenings (observe and adjust).
  • After two weeks a second active may be introduced.
  • Do not exceed 1x per week if a second active is in play. We recommend the use of A 0.5 DROPS / A 0.5 SERUM or A 1.0 DROPS / A 1.0 SERUM once per week.
  • Minimize other leave-on products, too. Avoid makeup, moisturizers and sunblock.
  • Use only very mild products and very infrequently exfoliate. Exfoliation often increases visible pigmentation spots.
  • Discontinue entire regime for 7 days every month. Let skin rest, cleanse and leave-on REVIVE only.
  • TIP: Use REVIVE as a cleanser and a leave-on moisturizer to help keep visible blemishes in check.


  • Apply C 25 SERUM (1x-2x) per week, evenings.
  • After two weeks you may add any 302 active.
  • CERAMIDE SERUM or PRO HYA + would be excellent choices to use twice per week with C 25 SERUM.
  • If you have three actives in play, limit every active to once (1x) per week application.
  • NEVER have more than three actives in play during a week. Limit every active to once per week to keep skin fresh and not saturated if three are in play.
  • Minimize other products, especially makeup and moisturizers, avoid sunblock chemistry. Use REVIVE as cleanser, alternate with other cleanser, like 302 CLEANSER. Use REVIVE as moisturizer, too, especially if skin is unstable.

For your skin if these conditions exist:

  • Exfoliating acids usage is infrequent
  • Benzoyl peroxide free for 30 days
  • Not inflamed or visibly unstable
  • Sensitive but not visibly unstable
  • Light to average makeup usage

Not for your skin if these conditions exist:

  • Inflamed, unstable skin
  • Frequent exfoliation
  • Unusual oral medications causing skin instability (i.e. chemo, cortisones, thyroid meds) may cause erratic skin behavior.

Recommended frequency of use:

  • One to two times (1x-2x) per week (observe and adjust)
  • After one month discontinue current active(s) regimen and allow skin to rest for a 7-10 days before resuming. This will allow skin reactions further out to be fresh and not weakened by over frequent or prolonged application periods.


Note: two or three cleansers are recommended to be cycled through per week for best skin results.

  • Any 302 Skincare Cleanser or FACE & BODY BAR

Additional actives while using C 25 SERUM:

  • Do not introduce another active for 2 weeks.
  • Do not apply a second active more often than 2x per week.
  • You could have a third active in play.
  • Three actives per week = apply once per week (maximum).
  • If you have two or more actives in play AND are exfoliating frequently YOU WILL cause skin instability.

Additional leave-ons acceptable:

  • CALMING MIST: CALMING MIST recommended if two or more actives in play.
  • REVIVE, anytime
  • REMEDY (small pea sized amount for entire face)


  • Exfoliation
  • Scrubs
