Amino Acids + B5

Hydration support in its most stripped-back form: The Ordinary Amino Acids + B5 pairs a 17% concentration of amino acids (and their derivatives) with 5% vitamin B5 in one lightweight serum. It's built for skin that feels dry, is starting to show fine lines, or has lost some of its bounce.

What it actually does

• Reinforces the skin's own moisture system. Amino acids occur naturally in the skin's Natural Moisturizing Factors — the brand says topping them up supports the barrier, elasticity and balance.
• Hydrates at and below the surface. The vitamin B5 component delivers hydration while assisting skin repair and, per The Ordinary, acting against irritation.
• Targets dryness, fine lines and loss of firmness — the three concerns this formula was designed around.
• Suits every skin type. Normal, dry, combination and oily are all listed by the brand.
• Minimal formula. Vegan, cruelty-free and gluten-free, free of sulfates, parabens, formaldehydes, phthalates, mineral oil and a long list of other exclusions, with under 1% synthetic fragrance.

How to use

1. Morning and evening, apply a few drops across the face.
2. Before creams — serums go on first, moisturiser seals them in.
3. Expect a tingle. A tingling feeling after applying is normal. If it's stronger than you'd like, mix the serum into another cream or serum at each use to soften it.

Questions

It tingles when I apply it — is that normal?

Yes, The Ordinary notes that a tingling sensation is expected with this formula. If it feels too intense, blend it with your moisturiser or another serum before each application to dial down the strength.

Where does it fit in my routine?

After cleansing (and any toner), before creams — both in the morning and at night. It's a hydrating serum, so it layers comfortably under moisturiser and SPF.
