Vitamin C 20% + Aloevera 10% + Hyaluronic Acid 1%

(15 customer reviews)

USD $17.00

A clinical-grade Vitamin C 20 % Serum formulated at pH 3.5 for optimal stability and deep epidermal penetration. This potent antioxidant brightens uneven skin tone, reduces hyperpigmentation, and combats environmental damage by neutralizing free radicals as shown in a 2013 study on topical antioxidants. With added hyaluronic acid and vitamin E for enhanced hydration and synergistic photoprotection, it stimulates collagen synthesis to firm fine lines and improve elasticity. Ideal for addressing melasma, age spots, and photoaging, this fast-absorbing, non-greasy serum is best suited for normal to combination skin.

Description

Vitamin C (L-ascorbic acid) is one of the skin’s most potent antioxidants, crucial for neutralizing oxidative stress caused by UV radiation and pollution, as demonstrated in a 2020 review of topical L-ascorbic acid. While oral intake yields limited dermal uptake, topical application at a 20 % concentration and low pH ensures maximum uncharged molecule penetration through the stratum corneum, producing visible improvements in brightness and texture within weeks.


Key Benefits

  • Antioxidant protection: Scavenges free radicals to prevent collagen degradation and premature aging, supported by clinical data in the Journal of Dermatological Science.

  • Brightening and lightening: Inhibits tyrosinase to reduce melanin synthesis and fade dark spots, confirmed by a 2015 clinical trial.

  • Anti-aging effects: Boosts collagen production by up to 30%, firming fine lines and wrinkles, as shown in a 2002 study on collagen synthesis.

  • Hydration support: Contains hyaluronic acid to draw moisture into the epidermis, reducing transepidermal water loss.

  • Synergistic photoprotection: Works with vitamin E to stabilize ascorbic acid and enhance UVA/UVB defense, based on findings in a 2001 photoprotection study.


Science of Topical Vitamin C

L-ascorbic acid remains the gold standard for topical vitamin C due to its superior biological activity, though its hydrophilicity and instability require careful formulation. By adjusting the pH to 3.5, the serum ensures vitamin C is predominantly uncharged, allowing efficient passage through the lipid-rich stratum corneum. Clinical research reveals that stable, low-pH formulations significantly elevate dermal ascorbate levels and improve photoaging parameters such as rough texture and laxity, as detailed in this 2006 study on skin penetration.


Formulation Details

  • 20 % L-ascorbic acid at pH 3.5 for maximal penetration and potency.

  • 1 % Hyaluronic acid to plump and hydrate.

  • Tocopherol (Vitamin E) to regenerate and stabilize ascorbic acid while providing additional antioxidant support.

  • Ferulic acid to further stabilize the formula and boost photoprotective activity, as outlined in a 2001 antioxidant synergy study.

  • Lightweight base for rapid absorption without greasiness.


How It Works

When applied, the low-pH environment converts L-ascorbic acid into its uncharged form, facilitating stratum corneum permeation. In the viable epidermis and dermis, vitamin C donates electrons to neutralize reactive oxygen species, preserving collagen and elastin fibers, as reviewed in Dermato-Endocrinology, 2012. It also inhibits tyrosinase, the enzyme driving melanin production, leading to gradual fading of hyperpigmented lesions, and acts as a cofactor for pro-collagen hydroxylase, accelerating skin repair.


Suitable Skin Concerns

Particularly effective for:

  • Melasma and hormonal hyperpigmentation

  • Age spots and sun-induced dark marks

  • Uneven skin tone and dull complexion

  • Early photoaging signs: fine lines and rough texture

  • Acne scars and post-inflammatory hyperpigmentation

Optimized for normal to combination skin that tolerates low-pH actives. Dry or sensitive skin types should introduce it gradually.


Usage Guidelines

  1. Patch Test: Apply a small amount on the inner forearm; wait 24 hours for tolerance.

  2. Cleanse: Use a gentle, pH-balanced cleanser.

  3. Apply Serum: Dispense 3–4 drops onto dry skin in the morning.

  4. Moisturize: Follow with a hydrating moisturizer.

  5. SPF: Always finish with broad-spectrum SPF 30+ to protect sensitized skin.

Consistent daily use delivers optimal results in 8–12 weeks.


Packaging and Stability

Encased in an airless, UV-protected bottle to prevent oxidation. Once opened, the serum maintains full potency for up to 6 months when stored in a cool, dark place.

FAQ

What skin types is Vitamin C 20 % Serum best for?
Normal to combination skin types that tolerate low-pH actives. Dry or sensitive skin may start every other day and build up.

Can I use this serum with retinoids?
Yes—apply vitamin C in the morning and retinoid at night to minimize irritation.

How long before I see results?
Improvements in brightness and texture typically appear within 8–12 weeks of daily use.

Is it safe during pregnancy?
Topical vitamin C is generally safe, but consult your healthcare provider before beginning any new skincare regimen.

Can it replace sunscreen?
No; while it enhances photoprotection, always apply broad-spectrum SPF 30+ each morning.
