- Ginkgo Biloba
- Ginkgo Biloba increases blood flow to the scalp and can accelerate hair growth rates. Better blood flow means more nutrients are available for the hair production process.
- Gotu Kola
- Gotu Kola is especially good at improving elasticity and reduce sagging. It boosts antioxidant activity, strengthenings the skin and increases blood circulation.
- Glycolic Acid
- (AHA) Glycolic Acid (AHA) exfoliates by loosening the “glue” that adheres dry, dead skin to healthy skin, and then dissolves away the dead skin. It is a superior form of exfoliation for mature skin because there is no rubbing or pulling the skin. There is also little to no peeling or sloughing sections, and limited redness or irritation after use. Skin is brighter, younger, softer, with few lines and wrinkles, and it glows like younger skin. In-office micro-needling with Glycolic Acid greatly reduces acne scars. (1) Glycolic Acid also promotes collagen production. Several at-home Glycolic Peel products are available.

- Grape Seed Extract
- Grape Seed Extract prevents breakouts and calms existing breakouts. Contains very high antioxidant levels to protect the skin against UV damage.
- Grapeseed Oil
- Grapeseed Oil is highly beneficial for both skin and hair. For hair, it is an outstanding moisturizer for brittle and dry hair. It soothes dry scalp skin. Regular Grapeseed oil scalp massages remove follicle-shrinking DHT. DHT is a hormone that accumulates on the scalp and can cause hair loss. Grapeseed Oil is nourishing to the skin and contains building blocks for collagen production. High in Polyphenols, Vitamins C, D, E and Omega 6, it treats dry skin, wrinkles, discoloration, and aging. Choosing an organic product is especially important when selecting a grapeseed oil.
- Green Tea
- Green Tea feeds and moisturizes the skin, calms irritation and is an excellent antioxidant. Topical Green Tea application can calm the irritation that aggressive topicals such as Retinol cause. Drinking green tea has anti-aging benefits from polyphenols. It can reduce sun damage, decrease collagen breakdown and increase cell regeneration.
