SkinCeuticals Glycolic 10 Renew Overnight

Is SkinCeuticals Glycolic 10 Renew Overnight right for you?

• If you have rough skin texture, dullness, or uneven tone — 10% glycolic acid at clinical strength is one of the most proven corrective actives available without a prescription.
• If you want a combined exfoliating and moisturising night treatment — the cream base provides hydration while the AHAs work overnight.
• If you are concerned about fine lines caused by sun damage or reduced collagen — glycolic acid stimulates dermal collagen synthesis in addition to its exfoliating action.
• If you are an intermediate skincare user ready to step up from a basic moisturiser — this is an effective upgrade that introduces meaningful exfoliation with a manageable side-effect profile.
• Not recommended for very sensitive skin, active rosacea, or anyone currently using prescription retinoids without clinical guidance.

How SkinCeuticals Glycolic 10 Renew Overnight works — the science

At 10% concentration in a leave-on overnight formulation, L-Glycolic Acid provides a meaningful chemical exfoliation that goes beyond what any rinse-off cleanser can achieve. Applied and left on skin overnight, the acid has time to thoroughly disrupt desmosomal bonds across the stratum corneum, accelerating the shedding of accumulated dead cells and revealing fresher epidermis with improved light-reflectance — the physical basis of skin "glow."

Crucially, glycolic acid at therapeutic concentrations does more than exfoliate. Research demonstrates that it upregulates dermal fibroblast activity and stimulates Type I and Type III collagen synthesis in the dermis — the same collagen fibres responsible for skin firmness and elasticity. The addition of 2% Phytic Acid (an antioxidant from rice bran) tempers any irritation potential and provides complementary brightening action by chelating the metal ions that catalyse free radical formation and melanin oxidation.

What you will notice — and when

Immediately — A warming sensation on application; skin looks smoother and more radiant by morning after the first use.

Week 1–2 — Skin texture becomes noticeably refined; fine surface lines look softer; pigmentation may begin to lighten.

Month 1+ — Established improvement in skin tone, texture, firmness, and radiance; fine lines visibly reduced; skin feels denser and more resilient.

How to use SkinCeuticals Glycolic 10 Renew Overnight

1. Apply in the evening only — this is a night treatment.
2. Cleanse and dry skin thoroughly before application.
3. Apply a thin, even layer to the face and neck, avoiding the eye area.
4. Do not layer additional moisturiser on top — this cream is hydrating enough on its own.
5. Always use broad-spectrum SPF 30 or higher every morning — glycolic acid significantly increases photosensitivity.

Key ingredients & what they do

Ingredient	What it does for you
10% Glycolic Acid	Clinical-strength AHA — exfoliates accumulated dead skin cells, stimulates collagen synthesis, and improves skin texture, tone, and radiance
2% Phytic Acid	Antioxidant and brightening agent from rice bran — chelates metal ions that drive pigmentation and free radical damage; calms potential irritation from glycolic
Hydrating cream base	Provides overnight moisture alongside the exfoliation — no need for a separate night moisturiser

Dr. Bangalee's clinical perspective

Dr. Bangalee Recommends

"The Glycolic 10 Renew Overnight is one of the most cost-effective treatments in the SkinCeuticals range — 10% glycolic in a well-formulated leave-on cream delivers results that previously required clinical intervention. I use it in maintenance protocols between peel sessions and for patients who want visible texture and tone improvement but aren't yet ready for retinol. The Phytic Acid addition is smart — it broadens the corrective effect while reducing the irritation that sometimes limits glycolic adherence."

What our patients say

"I wake up with genuinely different skin after using this — smoother, brighter, and my pores look smaller. It's the one product I tell all my friends about." Lindiwe, Umhlanga	"I have sun damage from years of outdoor work and my skin tone was very uneven. After two months of this overnight cream the improvement is significant — my skin looks years younger." Warren, Ballito	"Dr. B recommended this as an alternative to retinol which I was struggling to tolerate. It's been transformative — smoother, clearer skin with no flaking or redness." Refilwe, Morningside

Frequently asked questions

Question	Answer
Can I use this with retinol?	Not on the same night — using two strong actives simultaneously increases irritation risk. Alternate nights (glycolic one night, retinol the next) is a common protocol; always confirm with your treating practitioner.
Will it cause peeling?	Mild flaking is possible in the first 1–2 weeks as the skin adjusts. This is normal. If significant peeling or redness occurs, reduce frequency to every other night initially.
Is sunscreen really necessary the next morning?	Absolutely essential. Glycolic acid significantly increases UV photosensitivity — using this product without morning SPF will accelerate the very sun damage you are trying to correct.
Can I use it if I am having clinical peels?	Pause this product for 5–7 days before a chemical peel treatment. Resume once the skin has fully recovered. Confirm timing with Dr. Bangalee.
Is it safe during pregnancy?	High-concentration leave-on AHAs are generally avoided during pregnancy as a precaution. Consult your obstetrician or GP before use.
