Cosmetic serums have become popular as an important part of the skincare routine. For the past few years, these have been cherished for their targeted benefits. However, identifying key ingredients and preservatives in the serum that maintain their safety is equally important. Understanding how these compounds work helps ensure the longevity and stability of these skincare magic formulas.
Types of serums
Serums come in various types. We have mentioned a few as per specific skin concerns:
Hydrating serums
Hydrating serums are formulated with humectants such as hyaluronic acid and glycerin. They attract and retain moisture in the skin. They help to plump and smooth the skin's texture, ultimately providing a burst of hydration for a dewy complexion. Dry skin types are especially beneficial in harsh climates or during winter months.
Anti-aging serums
Anti-aging serums contain potent ingredients like antioxidants (vitamins C and E), peptides, and retinoids. These ingredients can combat fine lines, wrinkles, and other signs of aging by promoting collagen production. Anyone concerned with visible signs of aging can benefit from anti-aging serums.
Acne-fighting serums
Acne-fighting serums typically contain active ingredients such as salicylic acid, benzoyl peroxide, or tea tree oil. These ingredients unclog your pores and control excess oil production. Oily or acne-prone skin types can benefit from these serums.
Two important preservatives in serums
Alpha Terpene
Alpha terpenes come from natural sources like plant extracts. They serve dual roles in serums. First of all, they act as antioxidants, shielding skin from environmental stressors like UV rays and pollution. Moreover, alpha terpenes have anti-inflammatory properties that can calm irritated skin and reduce redness along with maintaining serum’s stability. Their presence in serums enhances skin resilience and promotes a healthy complexion.
Gamma Terpene
Gamma terpenes are another class of natural compounds found in essential oils and botanical extracts. They possess antimicrobial properties which can prevent the growth of harmful bacteria and fungi in skin care products. This preservation effect in serums ensures that active ingredients remain potent and safe for extended use. Moreover, gamma terpenes contribute to the serum's shelf life.
