KELVS Lactic Acid 5% Serum | Lactic Acid & Hyaluronic Acid | Smooth Skin Texture & Even Tone
About This Serum
KELVS Lactic Acid 5% Serum is a gentle yet highly effective chemical exfoliant formulated with Lactic Acid 5% and Hyaluronic Acid 1% to resurface, brighten, and deeply hydrate the skin in one step. Unlike physical scrubs that can cause micro-tears, Lactic Acid dissolves dead skin cells at a chemical level — revealing smoother, clearer, more even-toned skin underneath without any abrasive friction.
Precisely pH-balanced at 3.5–3.8 for maximum exfoliating efficacy, and paired with Hyaluronic Acid to counteract any dryness, this serum is the ideal solution for anyone dealing with rough texture, dullness, dark spots, or an uneven complexion.
Why Lactic Acid 5%?
Lactic Acid is an Alpha Hydroxy Acid (AHA) derived from milk. It is widely considered the gentlest AHA available — making it the ideal entry point into chemical exfoliation, especially for sensitive or dry skin types. At 5% it delivers effective surface exfoliation without the aggressive irritation that higher concentrations can cause:
- ✅ Dissolves dead skin cell buildup for instantly smoother texture
- ✅ Unclogs pores and prevents blackhead formation
- ✅ Fades dark spots, hyperpigmentation and post-acne marks
- ✅ Stimulates natural skin cell turnover for a fresher complexion
- ✅ Reduces the appearance of fine lines and rough patches
- ✅ Gentler than Glycolic Acid — suitable for dry and sensitive skin
Why Hyaluronic Acid 1%?
Chemical exfoliants can sometimes leave skin feeling dry or tight — which is exactly why we paired Lactic Acid with Hyaluronic Acid at 1%. Acting as a powerful humectant, it immediately draws moisture into the freshly exfoliated skin, keeping it plump, comfortable, and hydrated throughout the process. The result is exfoliation without compromise — smooth and bright, never dry or stripped.
pH 3.5–3.8 — The Critical Factor for AHA Efficacy
AHAs like Lactic Acid are only effective within a specific low pH range. Our formula is precisely calibrated at 3.5–3.8 — the scientifically established optimal range for Lactic Acid to exfoliate effectively while remaining safe for skin. This is a detail many generic serums get wrong, resulting in products that are either too weak to work or too harsh to tolerate. KELVS gets the balance right.
- ✅ Smooths rough, uneven skin texture with regular use
- ✅ Brightens dull complexion by removing dead skin cell buildup
- ✅ Fades dark spots, hyperpigmentation and post-acne marks
- ✅ Unclogs pores and refines skin surface
- ✅ Deeply hydrates while exfoliating — no dryness or tightness
- ✅ Reduces the appearance of fine lines and rough patches
- ✅ Gentler than Glycolic Acid — suitable for sensitive and dry skin
- ✅ Precisely pH-balanced for maximum efficacy and safety
⚠️ Important: Lactic Acid increases skin sensitivity to UV radiation. Always apply a broad-spectrum SPF 30 or higher every morning when using this serum. We recommend starting with nighttime use only and gradually introducing morning use as your skin adjusts.
How to Use
- Cleanse your face thoroughly and pat completely dry
- Apply 2–3 drops of serum onto your fingertips
- Gently press and pat into face and neck — avoid the eye area
- Allow the serum to absorb for at least 10 minutes before applying other products — this gives the acid time to work at its optimal pH
- Follow with your regular moisturizer to seal in hydration
- Begin with nighttime use only — 2 to 3 times per week — and increase frequency gradually as your skin adjusts
- Always apply SPF 30+ every morning without exception when using any AHA serum
- Visible improvements in skin texture and tone typically appear within 3–4 weeks of consistent use
Frequently Asked Questions
Q: What is Lactic Acid and how does it work on skin?
Lactic Acid is an Alpha Hydroxy Acid (AHA) that works by breaking down the bonds holding dead skin cells together on the surface of the skin. This process — called chemical exfoliation — allows dead cells to shed naturally, revealing the fresher, smoother skin underneath. Unlike physical scrubs, it exfoliates evenly across the entire skin surface without causing irritation or micro-tears.
Q: Is Lactic Acid suitable for sensitive skin?
Yes — Lactic Acid is actually the gentlest of all AHAs, making it the preferred choice for sensitive, dry, or first-time exfoliant users. Its larger molecular size means it penetrates the skin more slowly and evenly than Glycolic Acid, resulting in effective exfoliation with significantly less risk of redness or irritation. We still recommend starting with 2–3 times per week and patch testing before full use.
Q: Can I use this serum every day?
We recommend starting with 2–3 times per week at night to allow your skin to adjust to chemical exfoliation. Once your skin has built up tolerance — usually after 3–4 weeks — you can gradually increase frequency. Daily use is possible for some skin types but is not necessary to see excellent results.
Q: Why does pH matter so much for Lactic Acid serums?
AHAs like Lactic Acid are only active and effective within a low pH range of approximately 3–4. At higher pH levels, the acid becomes neutralized and stops exfoliating. Many budget serums are formulated at the wrong pH, making them ineffective despite listing Lactic Acid on the label. KELVS precisely calibrates this serum at pH 3.5–3.8 to ensure you are getting a product that actually works.
Q: Can I use this serum with other KELVS serums?
Yes, but with care. Avoid using Lactic Acid on the same night as other strong actives like Retinol or high-concentration Vitamin C as this can cause irritation. It pairs well with the KELVS Hydration Serum or Niacinamide Serum on alternate nights. Always apply Lactic Acid first on clean dry skin, wait 10 minutes, then layer other products.
Q: Do I absolutely need to use sunscreen with this serum?
Yes — this is non-negotiable with any AHA product. Lactic Acid increases your skin's sensitivity to UV damage by removing the outermost protective layer of dead skin cells. Using this serum without daily SPF will worsen pigmentation, cause sunburn more easily, and undo all your brightening results. Always apply a broad-spectrum SPF 30 or higher every single morning.
Q: How is this different from a physical scrub?
Physical scrubs use abrasive particles to manually remove dead skin cells, which can cause micro-tears, uneven exfoliation, and irritation — especially on sensitive or acne-prone skin. Lactic Acid chemically dissolves the bonds between dead skin cells, allowing them to shed evenly and gently across the entire skin surface. The result is smoother, more even exfoliation without the risk of physical damage.
