Smoother, clearer skin with pores that look smaller.

Your skin feels rough to the touch, your pores look bigger than you would like, and old blemishes leave your tone uneven.

Active Serum lifts away built up surface cells, refines texture and minimizes the look of pores, so skin looks smoother, clearer and more even toned. It works through botanical exfoliants from sugarcane, bilberry and white willow bark, plus arbutin to even the look of tone, in one lightweight serum. It is the brand's cult classic for good reason.

Who It Is For

Congested skin, visible pores, rough texture, small bumps, uneven tone and sun damage, on any skin type, including skin that flushes easily.

Acne Safe

What You Will See, and When

Skin feels smoother within the first few uses. No timeline is published, so give it eight to twelve weeks of consistent use to judge tone and texture.

How to Use

Shake well before each use. Morning and night after cleansing, mix three drops of Active Serum with five drops of Retexturing Activator in your palm, or one to two drops with one pump of Hydra-Cool Serum if that is your pairing, then smooth evenly over face and neck. A slight cooling tingle is normal. In the morning, finish with sunscreen as your last step.

The Science

Hydroxy acids loosen the bonds that hold dead cells to the skin's surface, so skin looks smoother and reflects light more evenly. Alpha hydroxy acids work on the surface; beta hydroxy acids are oil soluble, so they reach into pores. This formula sources its acids botanically, from sugarcane and bilberry on the alpha side and white willow bark on the beta side.

Arbutin is a plant derived molecule that slows tyrosinase, the enzyme that starts pigment production, which is how it helps even the look of tone over time.

Questions

Is the tingle normal?Yes. A slight cooling tingle as it goes on is expected and fades quickly.
Morning or night?Both, mixed each time with Retexturing Activator or Hydra-Cool Serum, whichever your routine pairs it with. In the morning, finish with sunscreen.
What does it feel like?A light, fast absorbing serum that leaves skin smooth.

Why a Routine Made for You Works Better

General advice is written for everyone, so it has to assume nothing about you. It can tell you what is safe. It cannot tell you what will work for your skin.

Skin changes when it is challenged just enough, then given time to recover and adapt. That amount is different for every person, and it moves as your skin gets stronger. Ask too much and your skin spends its energy recovering instead of improving. Ask too little and nothing changes. Finding that point for you, and moving it at the right time, is where results come from.

Where that point sits depends on:

  • Your skin: its history, how it reacts, and what it is doing today
  • Your health: hormones, medications, pregnancy and any condition that changes how skin behaves
  • Your lifestyle: sleep, stress, diet, sun, exercise and climate
  • Your routine: what you use now, and what has and has not worked before
  • Your goals: what you most want to change
  • Your expectations and timeline: how soon you want to see change, and what is realistic for your skin
  • Your consistency: how much time and how many steps you will keep up with, because the best routine is the one you actually do
  • Your treatments: what you have had and what you have planned

A skin therapist weighs all of this, builds a routine you can keep, and adjusts it as your skin responds. That is why we guarantee our products when they are part of a routine designed by one of our skin therapists. If you have been reading general advice, bring your questions. We will help you sort out what applies to you and what does not.
