Oat Milk PHA Serum


Over-exfoliation is the new plague in skincare. While acids do many wonders for the skin, too much too soon can damage the skin barrier and sensitize the skin.

In today's world, where brands compete for the highest % of acids, EqualRXN took a more holistic approach and created the Oat Milk PHA Serum. Oat Milk PHA Serum is an acid product that builds up the skin barrier instead of damaging it. Containing 5% lactobionic acid, an extremely gentle, hydrating (more than glycerin) yet effective polyhydroxy acid, this milky serum quickly boosts water retention, locks in moisture, and gently exfoliates to give a more refined, even, and glowy skin complexion without any irritation.

The benefits of lactobionic acid are further enhanced with oat milk and snow mushroom polysaccharide to repair, reduce redness, and plump up the skin to reduce the appearance of pores and fine lines, it's truly an all-in-one serum.



Lactobionic Acid (5%) A new generation of ultra-gentle yet effective acid that does more than just to exfoliate - it plumps up the skin, minimizes the appearance of pores, and aids in ingredient penetration.

Oat Milk Complex (2%) Rich in proteins, saponins, and beta-glucan, this complex soothes the skin and builds a healthier skin barrier.

Snow Mushroom Polysaccharide Nutrient-dense polysaccharide forms a protective barrier, locks in moisture, and calms the skin.

Beta Glucan & Saponins A strong inflammation reducer promotes wound healing and acts as an immunomodulator to decrease sensitivity.

Seed Butters 4 types of high antioxidant-containing seed butters nourish and soften the skin.

        Gentle yet effective

        I have sensitive skin and have tried low percentage AHA’s that still burned so I was looking for something to work for my skin. I’m so glad I found this! So gentle and hydrating yet still effective enough to exfoliate and give the skin a beautiful glow. It’s the perfect combination and exactly what I’ve been looking for!

        • What is your skin type? CombinationSensitive

        The perfect serum??

        I have sensitive, combo skin that unfortunately just doesn’t really tolerate vit c, niacinamide, or AHAs. Finding a “glow” serum that works for me has been a trial, but this serum turned out to be such a winner! I use it nightly with a (very) low strength retinol and my skin has honestly never been softer or smoother. Will 100% be rebuying this when I run out!

        I have keratosis pilaris on my face and this does such a nice job of gently exfoliating it! It’s super hydrating as well!
