Editorial verdict

The By Wishtrend Pure Vitamin C 21.5 Advanced Serum is a potent serum lauded by reviewers for its significant brightening effects and ability to diminish hyperpigmentation and acne scars. Its high concentration of pure Vitamin C makes it particularly effective for addressing dullness, uneven skin tone, and signs of aging. However, this potency also means it can be irritating for sensitive skin types, necessitating a gradual introduction to the routine. Users consistently emphasize the importance of proper storage, specifically refrigeration, to prevent oxidation and maintain its efficacy. Despite the potential for a less-than-pleasant scent, many consider the visible improvements in skin clarity and radiance to outweigh these minor drawbacks, making it a highly regarded product for those seeking a robust Vitamin C treatment.

What people love and don't

Based on ~6 reviews

The By Wishtrend Pure Vitamin C 21.5 Advanced Serum is a highly concentrated vitamin C serum designed to brighten skin, improve uneven skin tone, and address hyperpigmentation. Reviewers often note its effectiveness in delivering visible results, though some experience irritation due to its high potency, and it requires careful storage to prevent oxidation.

The good

Effective for brightening and evening skin tone

Reviewers consistently observe a brighter complexion and a more even skin tone after using this serum. This is attributed to the high concentration of L-ascorbic acid, a potent form of Vitamin C.

"My skin just looks more glowy. Vitamin C helps with collagen production and I found my fine lines on my forehead were definitely less pr"

Reduces hyperpigmentation and acne scars

Many users report a noticeable reduction in dark spots, post-acne marks, and other forms of hyperpigmentation, contributing to clearer-looking skin.

"The serum targets discolorations such as post-acne dark spots."

Improves skin texture and reduces fine lines

Some reviewers note an improvement in skin texture, with a smoother feel and reduced appearance of fine lines, suggesting anti-aging benefits.

"Vitamin C helps with collagen production and I found my fine lines on my forehead were definitely less pr"

Quick absorption and non-sticky finish

Despite its potency, the serum is praised for its thin, watery texture that absorbs quickly into the skin without leaving a sticky residue.

"Like Wishtrend claims, this serum is thin and watery, and absorbs quickly. It is also not sticky at all like they claim."

The trade-offs

Potential for irritation, especially for sensitive skin

Due to its high concentration of pure Vitamin C, some users, particularly those with sensitive skin, experience tingling, redness, or dryness, indicating a need for cautious introduction.

"If you have sensitive skin, it’s best to do a patch test first, or start with a serum that has a lower concentration of Vitamin C to avoid irritation."

Susceptible to oxidation

Reviewers highlight the instability of Vitamin C, noting that the serum can oxidize quickly if not stored correctly, such as in a refrigerator, leading to a diminished efficacy.

"Vitamin C can also easily break down when exposed to light or air. I often hear about it oxidizing. Luckily, I haven’t had that happen with the Wishtrend Pure Vitamin C 21.5% Advanced Serum I am have been using the last few months. To prevent oxidation, you should also keep it refrigerated."

Unpleasant scent for some

A few reviewers mention an artificial orange juice-like smell that they find off-putting, potentially due to certain ingredients in the formulation.

"Unfortunately, the smell may put you off. Despite the lack of ascorbic acid, it does smell like artificial orange juice, possibly because of the presence of castor oil and natto gum."

Reach for it if

Reviewers with dull skin, acne scars, uneven skin tone, and those seeking anti-aging benefits for their skin. It is recommended for normal to oily skin types.

Skip it if

Individuals with sensitive skin should approach this high-concentration vitamin C serum with caution, as it may cause irritation.
