What the product description says
“Niacinamide 5% (or vitamin B3) to minimise hyperpigmentation and even skin tones and texture.”
Source: BY TERRY

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~3.7–5.6%
Ascorbic acidUnder-dosedThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.05–0.15%

What the product description says
“Plumps, protects, nourishes, regenerates, smooths, and evens skin.”
Source: BY TERRY

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: arginine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: arginine, caprylic/capric triglyceride.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.

What the product description says
“Peptides (5%) - the perfect youth-boosting actives - to improve skin elasticity and stimulate collagen production for firmer, smoother skin and a curved oval.”
Source: BY TERRY

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: tetradecyl aminobutyroylvalylaminobutyric urea trifluoroacetate.

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.

Product summary

"BY TERRY - Hyaluronic Global Serum" is effective for: Evens skin tone, Moisturizing, Anti-aging and Anti-blemish

Ingredient callouts

  • A good concentration of Niacinamide (3.70% - 5.60%). 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.
  • This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.05% - 0.15%) it cannot have a noticeable benefit for the skin.
  • Humectants (hyaluronic acid 0.10% - 0.35%, sodium acetylated hyaluronate 0.10% - 0.45%, hydrolyzed hyaluronic acid 0.10% - 0.45%, sodium hyaluronate 0.30% - 0.75%, arginine 0.35% - 0.85% and glycerin 4.60% - 6.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
