Review: Wishtrend 21.5 Pure Vitamin C Advanced Serum

Or dreamy skin rejuvenation part two, part one being the gooey snail cream

Vitamin C serums seem to be the main competitor for retinol. Studies have shown whitening, brightening, and collagen production effects with consistent use. Bloggers are singing massive praise! When you search on google you are immediately met with this summary:

The antioxidant properties of vitamin C (ascorbic acid) and its role in collagen synthesis make vitamin C a vital molecule for skin health. Dietary and topical ascorbic acid have beneficial effects on skin cells, and some studies have shown that vitamin C may help prevent and treat ultraviolet (UV)-induced photodamage.

All good news right? Is this the new miracle step you need in your routine? Will you finally fade all of that acne scarring and fine lines?

Possibly! Keep in mind vitamin C is fickle. It’s expensive, expires quickly, and requires some extra care. Don’t use retinols, AHAs, or other chemical exfoliators while using vitamin C serum. They may work together in a routine but make sure you research, research, research! You must wear sunscreen at all times from up-ed sensitivity with use. Is it all worth it? Let’s see how one does.

Wishtrend’s Pure Vitamin C 21.5 Advanced serum is described as:

Pure Vitamin C21.5 Advanced Serum has been transformed to have even greater hydration and absorption without the stickiness. It conditions and restores balance to replenish and retain moisture in the skin with the optimal 21.5% of pure vitamin C.

Okay, there actually isn’t much information into what this serum actually promises on the purchasing page. Instead, they just list comparisons to the old formula so I’m going to nab the claims from the Vitamin C20 page.

Proved Effectiveness.

Original Pure Vitamin C20 Serum not only offers whitening, exfoliation and pore care effect, but also helps smooth the rough area on your skin, caused by spots or acne breakouts, when used regularly or long term. After using the serum, research shows positive result on skin condition.

Out of 2075 respondents :

• 97.91% said, Skin looked brighter and more defined complexion.

• 96.00% said, The serum reduced unwanted skin pigmentation and blemishes.

• 92.20% said, Positive skin improvement after first usage.

• 86.52% said, The serum smoothen out uneven texture.

Those are a lot of promises, but nothing too unusual for what vitamin C is suppose to offer the skin. You receive a 30ml bottle for $25 USD. The bottle comes closed with a separate dropper lid. It must be stored in the fridge and in low light (hence the brown bottle)! Light, heat, and exposure to oxygen make the active ascorbic acid deteriorate quicker. The better you store this, the longer it will last.

Ingredients: Hippophae Rhamnoides Water (70%), Ascorbic Acid (21.5%), Sodium Lactate, 1,2-Hexanediol, Sodium Hyaluronate, Panthenol, Cassia Obtusifolia Seed Extract, Allantoin, Xanthan Gum, Ethyl Hexanediol

Ingredients have been minimized from the original Vitamin C 20 serum, narrowed down from 29 to a key 10 ingredients. For sensitive skin types, this is a great improvement! Less worry for an extra potential allergen 😀  CosDNA does not flag of these as for potential acne or irritation but not all of ingredients have ratings. The worst things listed are for safety, sodium lactate (4) and ethyl hexanediol (3).


1) After cleansing, at the last step of your basic care, apply an adequate amount to the face, dividing up the portions and applying each small portion to different areas. Lightly tap the area to help absorption.

2) Gently massage the whole face using your palms about 2-3 times to ensure full absorption.

Following the given directions alone, you might not see any results. Why? PH matters in order to make this work! Ideally, use a ph balanced cleanser and follow with a ph balanced toner. Wait for the toner to dry completely before applying the serum.

At this point you can choose to apply the serum in two ways: 1. apply 1 – 2 drops on each section of the face (cheek, forehead, etc.) to apply a thin layer on the face, wait 15 – 20 minutes, and apply other serums and moisturizers on top. OR 2. apply 3-4 on each section for a thicker layer on the face, wait 15 – 20 minutes, remove excess serum with water or toner, and continue with your moisturizing routine.

I usually used method two. It only takes 15 minutes for you skin to absorb the vitamin C and since the serum is quick to expire there is no need to save precious drops. On first use, there will be a light tingling sensation, but it will disappear over time as your skin adjusts to the serum. There is a light stickiness and scent but nothing too strong. If you leave the serum on the stickiness with stay. Be careful about how much you put on if you are not going to wash the excess off, it can potentially stain your skin orange.

Note: My brows were filled in differently (arched in the before, straight in the after) and I am not lifting them in either photo

After 3 months of use, I love this. I use it once-every-other-day in the evening and it has yet to turn completely bad (but the color has darkened). My skin looks fresher and plumper! My skin feels firmer and absorbs moisturizers better! Now, I’m using it in combination with my snail serum (pictures repeated in that review too) so the lessening of wrinkles could be attributed to both but when I tested it without the snail cream the effects are still noticeable.

If you are thinking about it, absolutely give Wishtrend Vitamin C 21.5 a try. Even after a week long vacation without it I was ready for it to be back into my routine. It adds a bit of extra time and care in your routine but the effects are worth the price to pay!
