What is the professional Biodroga Skin Booster 15% Vitamin C Serum?
This 50 ml bottle is the professional back-bar size of Biodroga Medical Institute Skin Booster 15% Vitamin C Serum. The formula centers on 3-O-ethyl ascorbic acid, a stable vitamin C derivative. It holds this derivative at a 15% concentration and pairs it with tranexamic acid.
Estheticians use it both as a serum step within a facial and as a source bottle. From that bottle, they portion out client take-home samples. For this reason, its size goes well beyond the small retail bottle.
Key benefits
- Facial-ready brightening step: the stable vitamin C is formulated to help skin look more even and radiant, suited to layering into a treatment protocol.
- Targets the look of uneven tone: tranexamic acid works alongside the vitamin C to support a more balanced-looking complexion, including redness-prone areas.
- Doesn’t skip hydration: sodium hyaluronate keeps the formula from feeling drying under other treatment steps.
- Economical at volume: the 50 ml fill brings the per-application cost down for a serum used in most facials.
Key ingredients
According to the product’s published ingredient list, 3-O-Ethyl Ascorbic Acid sits at the core of the formula. This stable vitamin C derivative has a concentration of 15%.
In addition, Tranexamic Acid works alongside it to help address the look of unevenness and redness. Sodium Hyaluronate then adds a layer of hydration, so the serum doesn’t feel stripping. Finally, the formula carries no added fragrance.
How to use the Skin Booster 15% Vitamin C Serum
- Cleanse and tone skin as the first steps of the service.
- Then apply a few drops to face and neck as a dedicated serum step in the treatment sequence.
- Massage in fully before moving to the next product layer.
- Afterwards, follow with moisturizer to close out the service.
- When dispensing a portion for home use, remind the client to wear daytime sunscreen, standard practice with any vitamin C serum.
Who the professional 15% Vitamin C Serum is for
This bottle suits estheticians who build vitamin C into their standard facial sequence. It also suits those who like to send clients home with a sample poured from the same bottle used in-treatment. Rather than stocking a separate retail SKU for that purpose, they pour from one bottle.
Retail size vs. professional size
At 50 ml, this professional back-bar bottle costs less per application than the 15 ml retail bottle. The saving applies once the serum is a regular part of the treatment menu. However, the smaller retail size better suits a client who only wants their own bottle for home use.
