Instant, cooling hydration that visibly calms your skin.

After sun, travel or shaving your skin feels dry, warm and stressed, and you want relief the moment something touches it.

Hydra-Cool Serum floods skin with lightweight hydration and a cooling feel that visibly soothes on contact. Sodium hyaluronate draws water into the surface, vitamin B5 nourishes, and centella and mushroom extract add antioxidant support. It is gentle enough for sensitive skin and layers under anything.

Who It Is For

Every skin type, especially skin that is easily flushed, congested, dehydrated or showing sun damage, and skin recovering post procedure.

Acne Safe

What You Will See, and When

Skin feels cooler and more hydrated immediately. In a controlled study, twice daily hyaluronic acid creams improved skin hydration and elasticity over 60 days.

How to Use

Morning and night after cleansing, smooth one to two pumps evenly over face and neck with your fingertips. If Active Serum is part of your routine, mix one pump with one to two drops of it in your palm and apply them together. Let it absorb before moisturizer, and in the morning sunscreen goes on last.

The Science

Hyaluronic acid holds large amounts of water in the skin. In a randomized, placebo controlled study of 76 women, 0.1% hyaluronic acid creams applied twice daily significantly improved hydration and elasticity over 60 days, and the lower molecular weight forms also reduced wrinkle depth. That study tested hyaluronic acid creams, not this serum.

Centella asiatica's triterpenes (asiaticoside, asiatic acid and madecassic acid) are antioxidants that lab studies link to collagen support and a calmer look in skin.

Questions

Why does it feel cool?A touch of menthol gives it a refreshing, cooling finish.
Can I layer it with other serums?Yes. Use it on its own or under any of your other serums.
Can I mix it with foundation?Yes. One or two drops in your foundation gives a dewy finish.

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.
