Arencia - Vitamin C Booster Shot, Pure Vitamin C

3-O-Ethyl Ascorbic Acid at 50,000ppm — Stable Vitamin C

That Stays Potent The most common reason Vitamin C serums fail is oxidation before results appear. 3-O-Ethyl Ascorbic Acid does not oxidise the way pure L-Ascorbic Acid does. The potency on day one is the same as on day sixty — and because it's pH-independent and non-irritating at this concentration, it can be used daily from the first application without the gradual introduction that pure Ascorbic Acid serums require.

Triple Brightening Mechanism — Vitamin C + Glutathione + Niacinamide

Most brightening serums address one step of the melanin pathway. This formula addresses all three simultaneously: the Vitamin C complex inhibits Tyrosinase at the production stage; Glutathione shifts melanin synthesis toward lighter phaeomelanin; Niacinamide blocks melanosome transfer to the skin surface. For UK skin managing post-acne marks, sun spots, and general uneven tone, the triple-mechanism approach delivers results that single-active brighteners cannot match.

Fragrance-Free, Alcohol-Free, Silicone-Free — Genuinely Sensitive-Skin Compatible Vitamin C serums are one of the most fragrance-contaminated skincare categories — because fragrance masks the metallic scent of Ascorbic Acid at high concentrations. By using a stable, odourless ester derivative, Arencia eliminates the need for fragrance masking entirely — delivering a formula that sensitive, reactive, and barrier-compromised UK skin can tolerate from the first use.

Gel-Cream Texture — Works Under SPF and Makeup The lightweight olive oil-derived gel-cream absorbs completely within seconds, leaving no residue and no barrier preventing sunscreen from adhering. This is the Vitamin C format for AM use under daily SPF — precisely when antioxidant protection against UV and pollution-induced free radical damage matters most.

Adenosine + Vitamin C — Brightening and Anti-Ageing in One Step Vitamin C (collagen synthesis stimulation + antioxidant protection) combined with Adenosine (direct collagen and elastin production stimulation) delivers measurable anti-ageing benefits alongside brightening results. For UK skin managing both pigmentation and early fine lines, this removes the need for a separate anti-ageing serum alongside a brightening one.

Step 1 — Cleanse and Tone

Apply after cleansing and toning, before moisturiser and SPF. The serum step is optimised on clean, product-free skin.

Step 2 — Dispense a Small Amount

A small amount (approximately a 5p coin in size) is sufficient for the entire face. The gel-cream formula spreads easily and goes further than it appears.

Step 3 — Press Gently into the Skin Press into the skin using fingertips rather than rubbing — the pressing motion encourages absorption. Focus on areas of concern: cheekbones, forehead, and any localised dark spots or hyperpigmentation.

Step 4 — Allow to Absorb (60 seconds) Allow to absorb fully before applying the next step — typically 30–60 seconds.

Step 5 — Apply SPF (AM) or Moisturiser (PM) In the morning, always follow with broad-spectrum SPF 30 or higher. Vitamin C provides antioxidant protection against UV-induced free radical damage — but not UV protection itself. SPF is non-negotiable after morning Vitamin C use to prevent new pigmentation forming while the formula fades existing marks.

Starting Protocol: If new to Vitamin C serums, begin every other day for 1–2 weeks before increasing to daily use.
