Frequently Asked Questions

What actives do TSA serums contain?

It depends on the line. Anti-aging serums contain Encapsulated Vitamin C 5%, Matrixyl 3000 Peptides 3%, and Orchid Stem Cells 2%. Anti-blemish serums contain Encapsulated Vitamin C 5%, Azeloglycine 5%, Licorice Extract 1%, and Tranexamic Acid 2%. Anti-acne serums contain Niacinamide 3-5%, Salicylic Acid 2%, and Nelpure 2%.

Why is Vitamin C encapsulated?

Vitamin C is one of the most unstable active ingredients in skincare; it oxidizes on contact with air and light, losing its effectiveness before reaching the skin. Encapsulation protects it until the exact moment it penetrates the skin, ensuring that the 5% concentration reaches its target intact.

What is Matrixyl 3000 and why is it in anti-aging serums?

Matrixyl 3000 is the gold standard of anti-aging peptides. It sends direct signals to skin cells to produce new collagen and repair wrinkles from within. In combination with Vitamin C, which provides the necessary fuel to synthesize that collagen, and Orchid Stem Cells that reconnect the cellular network, they form the complete regenerating system of the Ageless Lift line.

What is Tranexamic Acid used for in anti-spot serums?

Tranexamic Acid effectively inhibits melanin transfer, the process that generates dark spots, with excellent tolerability, even on sensitive skin. In serums for hypersensitive skin in the anti-spot line, Vitamin C is replaced by Niacinamide for greater tolerability.

Does the anti-acne serum contain Salicylic Acid?

Yes. 2% Salicylic Acid unclogs pores from within, dissolves accumulated sebum, and prevents the formation of new comedones. It works in conjunction with Niacinamide, which reduces inflammation, and Nelpure, which controls bacterial growth.

How long does the serum last once opened?

We recommend finishing the container within 3 months of opening to maintain the encapsulated active ingredients, especially Vitamin C, at their maximum potency.

Can I use the serum during pregnancy?

Yes, with one exception. Serums containing Tranexamic Acid (hyperpigmentation line) are not recommended during pregnancy or breastfeeding. The rest of the TSA serums do not contain retinoids and are safe. We recommend showing the INCI list to your doctor.

When in the routine should serum be applied?

After cleansing and before moisturizing. First, the lighter, more concentrated products, then the denser ones that seal in the active ingredients.

Serums are where true skin transformation happens. Their concentrated texture and high proportion of active ingredients allow them to penetrate deeper layers where conventional creams cannot reach and where real changes in firmness, tone, and clarity occur.

At The Spanish Alchemist, each serum is formulated with high-concentration encapsulated actives that are protected from the environment until the exact moment they penetrate the skin. The Ageless Lift line combines 5% Encapsulated Vitamin C, 3% Matrixyl 3000 Peptides, and 2% Orchid Stem Cells to stimulate collagen synthesis, repair wrinkles, and firm contours. The Even-Tone Glow line combines 5% Vitamin C, 5% Azeloglycine, 1% Licorice Extract, and 2% Tranexamic Acid to inhibit melanin production and even out skin tone. The Bye Breakouts line combines Niacinamide, 2% Salicylic Acid, and Nelpure to control breakouts, unclog pores, and reduce inflammation without compromising the skin barrier.

Each line is available for oily/combination, dry, and hypersensitive skin. Formulas for hypersensitive skin are adapted for maximum tolerability, fragrance-free, with soothing actives and adjusted concentrations.

Produced in daily batches and shipped within 48 hours from our laboratory in Alicante. Finish the container within 3 months of opening for maximum results.
