Works for

3-o-ethyl ascorbic acid
May help

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: 3-o-ethyl ascorbic acid.

3-o-ethyl ascorbic acidKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.3–1.9%
Anti-aging
Side benefit · Adenosine, 3-o-ethyl ascorbic acid
Works well

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

AdenosineKey activeEffect: HighMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~1–1.45%
3-o-ethyl ascorbic acidEffect: LowA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.3–1.9%
Moisturizing
Side benefit · Caprylic/capric triglyceride, Adenosine + 1 more
Works

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: caprylic/capric triglyceride, caprylyl glycol.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~3.1–4.7%
AdenosineKey activeEffect: MediumMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~1–1.45%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.1–0.35%
Anti-oxidation
Side benefit · 3-o-ethyl ascorbic acid, Adenosine
May help

This product contains antioxidants (3-o-ethyl ascorbic acid) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

Product summary

"Dr. Althea - Gentle Vitamin C Serum" is effective for: Evens skin tone, Moisturizing, Anti-aging and Anti-blemish

Ingredient callouts

  • A good concentration of Niacinamide (3.50% - 5.30%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
  • Adenosine 0.30% - 0.70%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
