Oat Milk PHA Serum

30 mL / 1 oz

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 supports the skin barrier. Containing 5% lactobionic acid, an extremely gentle, hydrating (more than glycerin) yet effective polyhydroxy acid, this milky serum hydrates and gently exfoliates to give a more refined, even, and glowy skin complexion.

The benefits of lactobionic acid are further enhanced with oat milk and snow mushroom polysaccharide to calm and visually plump the appearance of the skin. It's truly an all-in-one serum. 


What we love about it

[ SAY “NO” TO OVER EXFOLIATION ] Formulated with 5% lactobionic acid, an ultra-gentle but effective PHA, this serum gently exfoliates the skin to give it a glowy look.  

[ INTENSE HYDRATION ] Containing a whooping ~13% hydration ingredients like lactobionic acid, snow mushroom polysaccharide and glycerin, this serum hydrates, locks in the moisture, and soothes the skin.

[ SUPPORTS BARRIER HEALTH ] Combined with 2% oat milk and 4 different seed butters, this product helps to plump up the skin and support a more durable skin barrier.

[ All-IN-ONE SERUM ] Formulated with ingredients that support each other to target various skin concerns. Oat Milk PHA Serum firms and strengthens the skin to become healthier.

[ GREAT BASE SERUM ] Many ingredients work synergistically with our Oat Milk PHA Serum, such as a vitamin C serum, retinoids, or other acids, like AHAs and salicylic acid. It helps to boost skin hydration and provides controlled and gentle exfoliation.

[ FOR ALL SKIN TYPES ] Ideal for all skin types and suitable for all seasons, this serum is a great serum for calming the skin, blemishes and helps to hydrate dry skin.

      best gentle exfoliant

      After having a terrible reaction to a peel, I don’t think I’ll ever try another exfoliant again! This has always worked for me. It’s never irritating, and always leaves my skin texture so smooth. Love it!

      Great product for skin soothing

      Helped my skin to reduce redness and soothing

      I love this brand!

      I discovered this brand on tiktok because of this serum, and was immediately gravitated towards everything this brand advocates for. This was my first purchase from equalrxn, and I have no complaints. This product instantly adds hydration and glow to my skin, doesn't have a harsh smell, the amount of product that comes from 1 pump is perfect, and the packaging is so cute. Love everything about this brand.

      Holy grail!

      This manages to be gently exfoliating, calming, hydrating and have a great formulation.

      Another great product!

      I don't use it every day but I've been able to use it twice a week with a retinal on all the other days and I haven't experienced any dryness or any issues. I think that's pretty awesome because it's the only exfoliating product that's been able to do that and I tried a bunch that were supposed to be formulated for dry or sensitive skin. I am very impressed with Equalrxn. When they say a product will do something it most certainly does that. Very very effective but mild. I do not have acne, I have some blemishes here and there so people who experience that might want something stronger but I would definitely recommend this product because you don't need something harsh for it to work. Well done and will repurchase.

      Hydrating with gentle exfoliation

      Great product. I was surprised at the instant hydration that sank into my skin. I bought this and the toner together and I think they align to this brand's goal of soothing barrier protecting products.

      Love love love

      I not only use this product religiously, I use their Gumercindo serum at night and their mushroom toner. This is by far my favorite skin care brand.

      Katherine M

      I use this serum nightly in my routine and it make my skin hydrated and helps to keep my acne-prone skin clear. It’s the perfect product! I love how gentle and hydrating it is. It’s truly HG status.
