Quick Answer: Do you need both peptides and antioxidants?
They can work well together. Peptides and antioxidants perform complementary functions. Peptides support skin-signaling pathways associated with a firmer, smoother-looking appearance, while antioxidants help defend skin against oxidative stress caused by free radicals.
Pairing Enspri Peptide Plus, formulated with a combined 20% peptide complex solution, with Enspri Sheer Ceramide, a biomimetic lipid serum with squalene and vitamin E, provides complementary firmness, antioxidant, and barrier support in a streamlined routine.

What Are Peptides in Skincare?
Peptides are short chains of amino acids. In cosmetic skincare, certain peptides are used to support skin-signaling pathways associated with a smoother, firmer, and more resilient-looking appearance. Unlike exfoliating acids or retinoids, peptides do not rely on exfoliation or accelerated cell turnover.
Different cosmetic peptides are designed for different functions. Depending on the peptide and formulation, they may help improve the appearance of fine lines, firmness, elasticity, and surface texture.
What Cosmetic Peptides Can Support
- Skin-signaling pathways associated with a firmer-looking appearance
- A softened appearance of fine lines and expression lines
- Firmer, more resilient-looking skin
- Smoother-looking surface texture
- A gentle, non-exfoliating approach to visible signs of aging
Formulation Focus: Solution Complexes vs. Pure Peptides
Pure peptides are active molecules that may be used at relatively low concentrations depending on the specific peptide and formulation. Enspri Peptide Plus combines two established cosmetic peptide solutions: 10% Matrixyl® 3000 Solution and 10% Argireline® Solution, for a combined 20% peptide complex solution.
What Are Antioxidants in Skincare?
Daily exposure to UV radiation, pollution, and normal metabolic processes can contribute to the formation of reactive oxygen species (ROS), often referred to as free radicals. When reactive species accumulate, oxidative stress can contribute to visible signs of skin aging.
Antioxidants help neutralize reactive species and limit oxidative chain reactions. When an antioxidant such as vitamin E is paired with barrier-supportive lipids and emollients, a formula can provide both antioxidant support and conditioning to help maintain soft, comfortable skin.
Vitamin E
A lipid-soluble antioxidant that helps protect skin lipids against oxidative stress while conditioning the skin.
Biomimetic Squalene
Squalene is a naturally occurring component of human sebum. As an emollient in skincare, it helps support softness, suppleness, and moisture retention.
Grapeseed Oil
Provides lightweight emollient lipids that help condition the skin and complement a barrier-supportive formula.
Jojoba Oil
Rich in wax esters, jojoba helps condition the skin and support a soft, comfortable feel without a heavy finish.
Peptides vs. Antioxidants: What Is the Difference?
Peptides and antioxidants address different aspects of visible skin aging. Peptides are commonly used to support the appearance of firmness, texture, and fine lines, while antioxidants help defend against oxidative stress. Barrier-supportive lipids can complement both by helping maintain moisture and skin comfort.
| Category | Peptides (Peptide Plus) | Antioxidant + Lipid Support (Sheer Ceramide) |
|---|---|---|
| Primary Role | Supports smoother, firmer-looking skin and helps soften the appearance of fine lines. | Provides antioxidant and lipid support while helping reduce moisture loss. |
| Targeted Concerns | Fine lines, expression lines, loss of firmness, and uneven-looking texture. | Dryness, tightness, moisture loss, and everyday environmental stress. |
| Featured Ingredients | Matrixyl® 3000 Solution, Argireline® Solution, Tripeptide-10, Tripeptide-29, and hyaluronic acid. | Squalene, jojoba oil, grapeseed oil, and vitamin E. |
| Formula Texture | Lightweight, water-based serum. | Silky, lightweight lipid serum. |
| Routine Placement | Apply after cleansing and before richer moisturizers or lipid-based formulas. | Layer after lighter water-based serums. |
Why Peptides and Antioxidants Complement Each Other
Peptides and antioxidants do not depend on each other to work. Instead, they address different aspects of visible skin aging. Peptides can support a firmer, smoother-looking appearance, while antioxidants help defend skin against oxidative stress.
Pairing those benefits with barrier-supportive lipids creates a complementary approach that addresses visible firmness, environmental stress, moisture retention, and skin comfort.
Peptide Plus Serum Helps:
- Support firmer, smoother-looking skin
- Soften the appearance of expression lines

Pro Layering Tip: For comfortable layering and to help minimize pilling, apply lighter water-based serums such as Peptide Plus before richer lipid-based formulas such as Sheer Ceramide.
How to Layer Peptides and Antioxidant Lipid Support
When combining these formulas, layer primarily according to texture—from lighter water-based products to richer lipid-based products.
Common Skincare Mistakes to Avoid
- Overcomplicating your routine: Using too many active products at once can make a routine difficult to follow and may increase the potential for irritation.
- Judging peptides only by percentage: Different peptide ingredients and supplied peptide complexes have different recommended use levels. A larger percentage does not automatically mean a better formula.
- Ignoring barrier support: Hydration and barrier-supportive products can complement a peptide-focused routine, particularly when skin feels dry or tight.
- Treating antioxidants as a replacement for sunscreen: Topical antioxidants can complement a sun-protection routine, but they do not replace broad-spectrum sunscreen.
- Expecting immediate peptide results: Visible changes from cosmetic peptide products can vary depending on the formula, skin condition, and consistency of use.
