What are the key ingredients?
Jan Marini Skin Research C esta Serum is formulated with a potent blend of antioxidants, vitamins, and peptides that work together to improve the texture and tone of the skin.
One of the key ingredients in this serum is ascorbyl palmitate, a stable form of vitamin C that is known for its antioxidant properties. Vitamin C is a powerful antioxidant that helps to protect the skin from environmental damage, such as UV radiation and pollution. It also helps to brighten the skin and improve its overall tone and texture.
Another important ingredient in this serum is DMAE (dimethylaminoethanol), which is a natural compound that helps to firm and tighten the skin. DMAE has been shown to improve the appearance of sagging skin and reduce the appearance of fine lines and wrinkles.
The serum also contains hyaluronic acid, which is a powerful humectant that helps to hydrate the skin and improve its elasticity. Hyaluronic acid can hold up to 1000 times its weight in water, making it an excellent ingredient for improving the hydration levels of the skin.

What ingredients should I look for in Skincare?
Antioxidants
We’ve been hearing for years that antioxidants ARE the best anti-aging ingredients. Antioxidants protect the skin from free radicals, the unstable molecules that contribute to the formation of premature wrinkles and fine lines on the skin.Antioxidants can also helps fade spots, even out skin tone, and boost radiance.But our favorite Vitamin C serum is Carrot & Stick The Defence Serum. It contains 3 distinct types of Vitamin C that work together to help fight free radical damage. We recommend using it every morning.
Peptides
As you age, your body’s production of collagen and elastin slows down. These two proteins are responsible for your skin’s structural support. As a result, the skin loses its natural plumpness and smoothness.While collagen is necessary for maintaining youthful-looking skin, the collagen protein is too large to absorb into the skin topically. That’s why applying skin care products that contain collagen won’t provide the anti-aging benefits you’re looking for.This is where peptides come into action. Peptides are the building blocks of protein, and they are easily absorbed into the deeper layers of skin due to their smaller size.If you’re looking for a peptide serum, recommend Carrot & Stick The Repair Serum. It contains 7 plant-based peptides to promote plumper and smoother-looking skin. It also has skin-loving ingredients like hyaluronic acid and niacinamide.Retinol
Retinol is the go-to anti-aging ingredient recommended by dermatologists and skin experts. Retinol is clinically proven to minimize the appearance of fine lines and wrinkles, improve uneven skin tone, restore skin firmness, and shrink the appearance of enlarged pores.The only downside? Retinol can often lead to side effects like skin dryness, peeling, and irritation. Look for products that contain Hydroxypinacolone Retinoate, an ingredient that provides the same benefits of retinol but without the irritation. One that we recommend is this retinoid oil serum.What is the texture like?
Jan Marini Skin Research C esta Serum has a lightweight, silky texture that absorbs quickly into the skin. It is non-greasy and does not leave a residue on the skin, making it an excellent choice for use under makeup or other skincare products.
The serum has a slightly citrusy scent, which is due to the high levels of vitamin C in the formulation. However, the scent is not overpowering and dissipates quickly after application.
What is the return policy?
Jan Marini Skin Research offers a 30-day return policy for all of its products, including C esta Serum. If you are not satisfied with your purchase, you can return it within 30 days for a full refund or exchange.
