Signs of skin aging begins in the mid-20s and accelerates into your 30’s
-
Sun damage is the leading cause of premature skin aging -
Sun exposure generates free radicals that break down collagen and elastin -
The effects of prolonged sun exposure can continue to damage the skin for up to 16 hours after exposure. -
Collagen and elastin are vital for maintaining youthful skin
- The skin's ability to produce new skin cells slows down by about 10% each decade
- The average person will lose about 1% of skin thickness per year
AGE 20
- Skin's collagen production declines by about 1% each year.
- The skin's natural exfoliation process slows down, leading to a buildup of dead skin cells and a dull complexion.
- Fine lines and wrinkles may start to appear around the eyes and mouth
- Skin's sebum production may start to decrease, leading to dryness and an increased risk of fine lines and wrinkles
AGE 30
- By age 40, our skin's elastin production will have declined by about 1% each year.
AGE 40
- Our skin's sebum production will have decreased by about 25%.

Why Your Skin Needs Vitamin C (L-Ascorbic Acid):
- Vitamin C is the most abundant antioxidant in the skin.
- Antioxidants help the skin repair the damage caused by our environment that may lead to fine lines, wrinkles, dull skin, and uneven skin tone.
Therefore, vitamin C should be applied topically.
- Stimulates the production of new collagen and elastin
- Helps repair and reverse the damage caused by sun exposure
- Strengthens the skin barrier, protecting it from harmful free radicals
How Phyto-C Peels Away the Competition
Not all Vitamin C Skincare Formulas are equally effective:
- Ascorbyl Palmitate,
- Magnesium Ascorbyl Phosphate
- Sodium Ascorbyl Phosphate
- Tetrahexyldecyl Ascorbate are all common forms of vitamin C, however, they do not have the same antioxidant benefits that L-Ascorbic Acid has.
Many Vitamin C skincare products fail to deliver desired results because it is difficult to stabilize.
Companies use Vitamin C derivatives that are more stable but less effective such as:
Silicone-based formulations compromise effectiveness
Effective Vitamin C Formulations Must Meet 3 Criteria:
-
The correct form of Vitamin C: L-Ascorbic Acid -
The ideal pH level (3.2 - 3.5) -
Concentration between 15% and 20% - Lower concentrations may not sufficiently address signs of aging
- Higher concentrations can cause irritation without added antioxidant benefits
