Introduction to The Ordinary Buffet and Amino Acids + B5
The Ordinary has revolutionized skincare with its transparent formulations, minimalistic branding, and potent ingredients at an accessible price. Two of its most talked-about products are:
The Ordinary Buffet
A multi-technology peptide serum, The Ordinary Buffet is designed to tackle multiple signs of aging, including fine lines, wrinkles, and uneven texture. It features a powerful blend of peptides, amino acids, and hyaluronic acid to deeply hydrate, firm, and revitalize the skin.
The Ordinary Amino Acids + B5
This ultra-lightweight serum is focused on hydration support and strengthening the skin’s natural moisture barrier. It contains a 17% concentration of amino acids and their derivatives, along with 5% vitamin B5, making it an ideal choice for maintaining skin softness and elasticity.
While both serums aim to improve overall skin health, they are formulated to target different concerns, anti-aging vs hydration.
Key Ingredients: What’s Inside?
The Ordinary Buffet
This serum features a cocktail of anti-aging powerhouses, including:
- Peptides: These proteins support skin firmness and elasticity.
- Amino Acids (e.g., Arginine): Enhance skin hydration and repair.
- Copper Tripeptide-1: Known for improving skin renewal and reducing inflammation.
- Matrixyl 3000 & Matrixyl Synthe’6: Advanced peptide complexes that stimulate collagen production.
- Hyaluronic Acid: Delivers deep hydration and plumping effects.
Altogether, the formula contains over 50 active ingredients that help improve tone, texture, and signs of aging.
The Ordinary Amino Acids + B5
Formulated to mimic the skin’s Natural Moisturizing Factors (NMFs), this serum includes:
- 17% Amino Acids & Derivatives: Help maintain skin hydration and resilience.
- 5% Pro-Vitamin B5 (Panthenol): Offers both surface and deep hydration, supports healing.
- Water-based, Alcohol- and Oil-free: Ideal for sensitive or dehydrated skin.
This formula is especially beneficial for dry, tight, or moisture-depleted skin.
Texture & Absorption
The Ordinary Buffet
- Texture: Slightly viscous with a light gel-like consistency
- Feel: May feel a bit tacky upon application, but this dissipates quickly
- Absorption: Absorbs well into the skin, leaving it smooth and nourished
The Ordinary Amino Acids + B5
- Texture: Clear, watery serum with a mildly slick finish
- Feel: Lightweight and virtually weightless
- Absorption: Quickly sinks into the skin with minimal residue, works seamlessly with other products
Both serums are non-comedogenic and suitable for layering with other treatments.
How to Use Them in Your Routine
The Ordinary Buffet
- When: AM and/or PM
- How: Apply after cleansing and before heavier serums or moisturizers
- Best for: All skin types, especially those concerned with visible signs of aging such as lines, sagging, or dullness
Its formulation makes it a multitasking serum perfect for those who want one product to address several skin concerns.
The Ordinary Amino Acids + B5
- When: Morning and evening
- How: Apply a few drops to face and neck after cleansing and toning
- Best for: All skin types, particularly dry or dehydrated skin seeking hydration support
